PRIOR APPLICATION

[0001] The present application claims the benefit of priority to U.S. Provisional Application No. 61/798,062 filed on March 15, 2013, which is hereby incorporated herein by reference in its entirety.

FIELD OF THE DISCLOSURE

[0002] The subject disclosure relates to a system and method for transferring passengers between a water vessel and the water.

BACKGROUND

[0003] Water sports such as diving and snorkeling are very popular today. Many people enjoy diving and snorkeling from a boat in order to distance themselves from land or explore various underwater locations, such as coral reefs, shipwrecks, underwater sanctuaries, and the like. The act of entering the water from a boat and entering a boat from the water, however, can be an awkward, cumbersome and a rather unpleasant experience. This is particularly true for the novice or inexperienced diver. Inexperienced divers may be unable or unwilling to enter the water by jumping off of or falling away from either the boat or diving platform. Use of ladders can be also be cumbersome if not impossible, with diving or snorkeling equipment, such as flippers. BRIEF DESCRIPTION OF THE DRAWINGS

[00015] The subject disclosure describes, among other things, illustrative embodiments of a passenger transfer system to allow for rapid and unobtrusive transfer of passengers between a water vessel and the water.

[00016] One embodiment of the subject disclosure is related to a water vessel including an elongated planar member. The elongated planar member includes a sliding surface that extends between a first end and a second end. The first end is attachable to an interior portion of the water vessel. A relatively low friction surface is positioned along the sliding surface to allow for slideable transportation of a person between an interior portion of the water vessel and water along the elongated planar member and into the water. A towline provides a lifting force that is advantageous to retrieve the passenger from the water towards the interior portion of the water vessel along the sliding surface.

[00017] Another embodiment of the subject disclosure includes a process including deploying an elongated planar member having a relatively low friction sliding surface. The deployed elongated planar member extends between an interior portion of a water vessel and a surface of the water. A towline is extended from an interior portion of the water vessel into the water along the elongated planar member. The towline allows a passenger to be attached to one end of the towline. The towline is drawn toward the interior portion of the water vessel thereby drawing a person attached to the towline from the water. In particular, the person is drawn gracefully along the sliding surface and into the interior portion of the boat.

[00018] Yet another embodiment of the subject disclosure includes a passenger transfer system. The passenger transfer system includes an elongated planar member having a sliding surface extending between a first end and a second end. The first end of the sliding surface is attachable to an interior portion of a water vessel. A relatively low friction surface is positioned along the sliding surface. The sliding surface allows for slideable transportation of a person between an interior portion of the water vessel and the water along the elongated planar member. A towline is also included to provide a lifting force usable to retrieve the passenger from the water towards the interior portion of the water vessel. [00019] Passengers are able to enter and exit a water vessel, for example, by way of an inclined sliding surface extending from an interior of the water vessel to the surface of the water upon which the vessel floats. The sliding surface can be treated with a relatively low friction treatment in order to promote sliding of passengers along the inclined sliding surface. One end of the inclined sliding surface accessible from the interior of the water vessel is generally positioned at a height above the surface of the water upon which the water vessel floats. Gravity acts to draw passengers on the inclined sliding surface, away from the boat and towards the surface of the water along the incline sliding surface. An opposite end of the incline sliding surface can extend at least partially into the water, such that a passenger is allowed to slide gracefully into the water without experiencing any trauma as would be experienced in a sudden drop. A retrieval system can include a towline deployed into the water and accessible by a passenger when in the water. The towline can extend along a length of the incline sliding surface from a first end within the boat to a second end within the water. Upon grasping or otherwise attaching to the towline, the passenger can be drawn up along the incline sliding surface from the water to a position inside the boat.

[00020] In the following detailed description, reference is made to accompanying drawings, which form a part thereof, and within which are shown by way of illustration, specific embodiments, by which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention.

[00021] The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented to provide what is believed to be the most useful and readily understood description of the simple principles and conceptual aspects of the present invention. In this regard, no attempt is made to show structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention. The description taken from the drawings make apparent to those skilled in understanding how several forms of the present invention may be embodied in practice. Further, like reference numbers and designations in the various drawings indicate similar concepts for the different embodiments. [00022] FIG. 1A illustrates a top a planar view of a boat 100. The boat includes passenger seating 102 and the helm 104 or pilot station to allow for piloting the boat 100 between locations. The boat 100 also includes a motor 106 to facilitate transportation of the boat 100 between such locations. The boat 100 can include in the most general sense any watercraft. In the illustrative example the boat includes a passenger deployment/retrieval system 107 having an inclined sliding surface, or slide 108, extending away from a rear portion of the boat 100 and into the water 110 in a position away from the boat 100. One end of the inclined sliding surface 108 is accessible from a position within an interior of the boat such as the deck 112, allowing passengers to access the inclined sliding surface from within the boat 100.

[00023] In some embodiments, as shown, a platform 114 such as a bed or a seat can be positioned within the boat 100, e.g., above the deck 112 and abutting the end of the inclined sliding surface 108 that is accessible from within the boat 100. The illustrative embodiment also includes a towline 116 extendable along at least the length of the inclined sliding surface 108, extending from the end of the incline sliding surface 108 positioned in the water 110 to a position, e.g., the deck 112, within the interior of the boat 100. In at least some embodiments the towline 116 can be operated by a winch 118 or hoist system. Such a winch 118 can be operated manually, e.g., by way of a cranking mechanism or automatically, e.g., by way of a motor. One end of the towline 116 is accessible by the passenger and can include a harness 120 or other suitable attachment feature to facilitate attaching the passenger to the towline 116 during periods of retrieval of the passenger from the water into the boat.

[00024] FIG. IB illustrates a top planar view of the boat 100 with the slide portion 108 of the passenger deployment/retrieval system portrayed in a stowed

configuration. In some embodiments the incline sliding surface 108 can be adapted to pivot about a hinge 122. In some embodiments, a longitudinal axis of the hinge 122 can extend in alignment with an edge of the boat 100 such that the incline sliding surface 108 can pivot about the hinge 122 between a deployed position in a stowed position. In the illustrative example the hinge 122 is aligned at an end of the platform 114 abutting a proximal end of the inclined sliding surface 108 closest to the boat 100. In at least some embodiments, an opposite or distal end of the inclined sliding surface 108 is unattached or otherwise free, allowing the distal end of the inclined sliding surface 108 to pivot into and out of the boat 100. Namely, the sliding surface 108 can be raised towards the boat 100 allowing the inclined sliding surface 108 to fold back into the interior portion of the boat 100 as may be convenient or otherwise necessary for transportation of passengers between locations.

[00025] FIG. 2A illustrates a partial cross sectional elevation view of a rear portion of the boat 100 shown in FIG. IB. As can be seen from the illustration, the slide 108, when in a stowed position, rests in a horizontal position above the deck 112. In the illustrative example the slide 108 rests on the platform 114. It is understood that in at least some embodiments, the slide 108 could rest along the deck 112 itself, or along some other surface of the boat 100. An end of the hinge 122 is visible at a back end of the platform 114. In at least some embodiments, the boat 100 includes a door 124 or gate structure. The door 124 can be closed during periods when the passenger deployment/retrieval system 107 is not in use, e.g., during transportation of the boat 100. It is conceivable that the passenger deployment/retrieval system 107 can be used as additional seating or storage surface when in a stowed configuration as shown.

[00026] The slide 108 includes a seating area 128 suitably positioned for passenger seating when the slide is in a stowed position. The seating area 128 can be positioned along a side of the slide 108 opposite to the sliding surface 130. In the illustrative embodiment, the slide includes a substantially planar member having the sliding surface 130 on one side and the seating area 128 along the other side. It is understood that the seating area 128 can be a simple flat surface, a contoured surface, e.g., to accommodate one or more seated passengers, or a combination thereof. The seating area 128 can be formed from the same material as the supporting material of the slide 108. Slide materials can include one or more of metals, woods, plastics, fiberglass, composites and combinations thereof. The seating area of such materials can be smooth or patterned, e.g., with a stippling, engravings, etc.

[00027] In at least some embodiments, the seating area 128 can include a second material 130 positioned between the slide 108 and a seated passenger. The second material 130 can offer material properties that are similar to and/or differ from material properties of the slide 108. For example, a rigid slide 108 can be outfitted with a flexible material 130 offering cushioned seating for passengers. Flexible material can include foam rubber, upholstery, and the like. Alternatively or in addition, a smooth slide 108 can be outfitted with a second material 130 having a rough surface. The rough surface can provide a relatively high coefficient of friction to discourage sliding of seated passengers along the seating area 128, e.g., while the boat 100 is moving. The second material 130 can include one or more of a laminate, a paint, a framed structure, a solid structure.

[00028] In some embodiments, the slide 108 can be formed as an assembly including a door or gate. Thus the door or gate will be positioned in a closed configuration for passenger safety automatically when the incline sliding surface is configured in the stowed position. When the incline sliding surface is pivoted to the deployed position, the door or gate, attached to the inclined sliding surface, will be open allowing transport of passengers there through. For example, the door or gate can be configured to face toward the surface of the water along in underside of the slide 108 so as not to interfere with transport of passengers along the slide 108 in its deployed configuration. Once again, returning the slide 108 to its stowed position can automatically position the door or gate to its closed and secured position.

[00029] FIG. 2B illustrates the passenger deployment/retrieval system 107 in a deployed configuration. In the illustrative example the door 124 is hinged along a vertical axis. In operation the door 124 is swung open to allow the slide 108 to pivot around its hinge 122 extending through the open door 124, away from the back of the boat 100 and into the water 110 as shown. When deployed an end of the slide 108 can be configured to float upon the surface 126 of the water, and/or to extend beneath the surface 126 of the water. In the illustrative embodiment, the slide 108 end extends just slightly below the surface 126 of the water forming an angle #with a horizontal plane of the surface of the water. The upper and of the slide 108, e.g., at the hinge 122, is positioned at a height h above the surface 126 of the water. One or more parameters can be varied to control the angle θοί the incline slide 108, the length of the slide 108, in the height of the vessel end of the slide 108 above the surface 126 of the water. In some embodiments the angle #is selected to be relatively low. A low angle allows for graceful entry of passengers into the water, e.g., at relatively low velocity and graceful retrieval of passengers from the water, e.g., without too much lifting force is to cause discomfort. In some embodiments, the angle Θ is less than 45 deg. In other embodiments, the angle Θ is less than about 30 deg. In still further embodiments, the angle Θ can be less than 20 deg. 10 deg. or less. It is understood that in at least some embodiments, the slide 108 can be deployed to relatively steep angles, e.g., greater than 45 deg. or even greater than 60 deg.

[00030] One or more of the angle Θ, the height and the length of the slide can be controlled to provide a preferred entry velocity and/or transit or slide time of a passenger when in use. Namely, a relatively steep angle generally results in a greater entry velocity of passenger entering the water by way of the slide 108. A sliding surface 130 of the slide 108 can be configured to control an entry velocity. For example, a slippery sliding surface 130 presents a relatively low coefficient of friction, e.g., in a limiting sense, approaching a frictionless surface. Conversely, a sliding surface 130 presenting a less slippery surface, e.g., having a greater coefficient of friction, would tend to reduce the entry velocity of a passenger, all else being equal.

[00031] In some embodiments, a coefficient of friction can be controlled by one or more of a choice of slide surface material, a coverage pattern of the slide surface material, a configuration of the slide surface material, e.g., smooth, textured. In some embodiments, a surface can be varied, e.g., by varying a surface pattern or configuration of the slide surface according to one or more of passenger protocol, e.g., young versus elderly, passenger preference, e.g., daredevil versus cautions, environmental conditions, and the like. Variations of the surface configuration can be controllable by a mechanical means, e.g., introducing one or more of bumps or ridges upon variation of a mechanical system. Alternatively or in addition, variations of the surface configuration can be controllable by application of an actuating force, such as an electrical voltage. Application of an electrical voltage to a piezoelectric surface can vary the surface between a relatively smooth and a roughened surface according to a value of the applied voltage.

[00032] The towline 116 can be deployed generally along the length of the slide 108 in order to retrieve passengers from the water. In at least some embodiments, the winch 118 or hoist system is positioned within the boat 100 such that the towline 116 extends above the sliding surface 130 of the slide 108. At a transition between the proximal or upper portion of the slide 108 and the abutting end of the platform 114 can be configured to prevent undue stress and/or friction on either the passenger or the towline. For example the hinge 122 can include a radius, e.g., a rounded or barrel shape, and/or be recessed entirely or partially below the sliding surface 130.

Alternatively or in addition, abutting ends of the slide 108 and the platform 114 can be rounded or otherwise curved, and so forth. Accordingly, the towline 116 can come into contact with at least the hinge 122 or portions of the slide 108 and/or the platform 114 in the vicinity of the hinge 122. Such a configuration is advantageous in maintaining the towline 116 in close proximity to the sliding surface to provide a towing force that is generally directed parallel to the sliding surface.

[00033] It is understood that in at least some embodiments, the towline can be configured substantially parallel to the sliding surface 130, without necessarily contacting either the sliding surface 130, the slide 108 or the platform 114. For example, the winch 118 can be positioned at a greater height than illustrated in FIGs. 2A and 2B. At some winch heights, the towline 116 can be substantially straight, e.g., above and parallel to the sliding surface 130 of the slide 108 when deployed. In some embodiments, the winch height can be even greater such that the towline 116 forms a greater angle with respect to the surface 126 of the water than the slide 108. Such greater angles can facilitate pulling passengers along a the slide during passenger retrieval, while pulling the passenger towards an upright position as they approach the proximal or upper portion of the slide 108.

[00034] As illustrated, the winch can include a motor 132 operable to retrieve or extend the towline 116. An actuator 134 can be provided to control operation of the motor 132. For example, the actuator can be used to turn the motor 132 on or off. Alternatively or in addition, the actuator can be used to operate the motor in a preferred, or between different directions, e.g., retrieval or extension. In at least some embodiments, the actuator can be used to control performance of the motor, e.g., by adjusting one or more of a speed or a clutch or other safety mechanism to yield or otherwise remove a towing force upon detection of a snag. Thus, if a passenger becomes caught up or otherwise snagged during retrieval, the clutch can operate to remove the towing force at least until the passenger is freed.

[00035] It is also understood that the winch mechanism 118 can operate the towline 116 by means of a towline guide. Towline guides can include one or more of a boom or other suitable extension, a pulley, and the like to provide a preferred operational angle and/or position to the towline 116 during operation. For example, the winch 118 can be configured as illustrated in FIGs. 2 A and 2B, with the inclusion of a boom that extends at least partially over the platform 114. The towline 116 extends over or through the boom, e.g., by means of a pulley, positioned between the winch 118 and the slide surface 130.

[00036] Although the slide 108 is illustrated as a single member, it is understood that the slide can be configured from more than one members. The slide can be a relatively heavy structure, being configured to support the weight of one or more passengers during operation with a measured overdesign. Alternatively or in addition, the length of the slide 108 can be relatively long depending upon the aforementioned design criteria, e.g., the height, angle and so forth. Accordingly, movement of the slide 108 about a single hinge 122 as shown can require application of a significant amount of force. Deployment can be human assisted, e.g., by lifting the distal end of the slide from the stowed position over the deck 112. The slide 108 can be pivoted allowing gravity to facilitate deployment, e.g., allowing the slide 108 to drop into the water. Other resistive features, such as slow-close hinges, can be used to prevent sudden movement by applying a resistive force during operation.

[00037] It should be appreciated that retrieval of the slide could be quite challenging, depending upon certain factors, such as the length of the slide, its weight, deployed angle and so forth. In at least some embodiments, a control mechanism is provided to facilitate positioning and/or movement of a slide. Referring next to FIG. 3A, a portion of a vessel 300 is illustrated. The vessel 300 includes a passenger deployment and retrieval system 307 including a slide 308. The slide is configurable between a stowed position and a deployed position. In a deployed position, the slide 308 extends from a proximal end accessible from the vessel 300 and a distal end positioned on or at least partially under the water line 326. In the illustrative embodiment, the slide 308 includes an elongated rigid member that pivots about a hinge 322. A cable 309 is provided between the slide 308 and a winch mechanism 319. The cable 309 is attached to the slide 308, e.g., towards a distal end of the slide 308, as shown. The winch mechanism 319 applies a force 321 to the cable, causing the slide 308 to pivot about the hinge 322. In at least some embodiments, one or more of a boom 325, a pulley 331 or similar guiding device can be provided between the winch mechanism 319 and an attachment point 323 where the cable 309 is attached to the slide 308.

[00038] In some embodiments, the cable 309 can remain attached during deployment and use. In other embodiments, the cable 309 can be attached to the slide 308 selectively during periods of retrieval and/or deployment, or otherwise left detached from the side 308, e.g., during use by passengers in disembarking and embarking the vessel 300 by way of the slide 308. The particular configuration of the winch 319, cable 309, boom 325 and pulley 331 are merely examples of one possible configuration. Numerous other configurations are envisioned using one or more pulleys, and/or one or more booms, winches and so forth.

[00039] In some embodiments, the same winch 319 can be used to raise and lower the slide 308 and to retrieve passengers from the water 310. A detachable coupling can be attached to the slide 308 during operation of the slide. The detachable coupling can be detached from the slide 308 and attached to a harness device, such as those disclosed herein, for retrieving one or more passengers from the water. In other embodiments, multiple winches can be used.

[00040] It is also conceivable that in some embodiments, a motor mechanism 327 (shown in phantom) can be applied to one or more of the slide 308 and the hinge 322. In the illustrative embodiment, the motor mechanism 327 provides a driving force to rotate the slide 308 about the hinge 322. A gear train, or other suitable drive mechanism can be used to transfer force from the motor mechanism 327 to one or more of the slide 308 and the hinge 322. In some embodiments, the motor mechanism 327 provides sufficient torque to rotate the slide 308 about the hinge 322 without requiring the cable 309 and winch 319. [00041] Although the slide 308 has been disclosed as a single member extending between the proximal and distal ends, in some embodiments, the slide 308 includes an assembly of more than one slide segments. For example, the slide 308 illustrated in FIGs. 3A and 3B can include two or more segments. A first slide segment can extend between the proximal end and a slide joint. A second slide segment can extend between the slide joint and the distal end of the slide 308. In some embodiments, the slide joint can be positioned midway between the proximal and distal ends such that each slide segment is approximately the same length. Alternatively, the slide joint can be positioned closer to one or the proximal or distal ends such that the slide segments are unequal in length.

[00042] The slide joint can be a pivotal joint, e.g., formed using a second hinge. The slide joint can also be a slideable joint in which one segment slides with respect to the other. In some embodiments, the slideable joint allows the slide 308 to extend and retract telescopically, For example, a linear drive mechanism, such as a chain drive, a belt drive, or a gear drive such as a worm gear drive, can be driven by the motor mechanism 327 to extend and/or retract the slide 308. In some embodiments, e.g., telescoping embodiments, the pivotal hinge 322 disclosed herein is unnecessary, although a pivotal hinge can still be provided to provide fine adjustment, or to allow for variations in deployed position, e.g., according to wave motion, the vessel position, etc.

[00043] FIG. 4 is a partial cross sectional elevation view of another embodiment of a boat 400 having a passenger deployment/retrieval system 407 in a deployed configuration. In this example a towline 416 can be operated manually without a winch or hoist. For example a boat operator and or passengers positioned within an interior portion of the boat 400 can manually draw the towline 416 into the boat, thereby retrieving a passenger from the water to the interior portion of the boat 400.

[00044] A harness 450 is illustrated at a distal end of the towline 416. The harness 450 is shown as extending into the water 410, beyond a distal end of a slide member 408. This configuration allows a diver to grasp or otherwise engage the harness 450, without having to extend any portion of their body out of the water 410. Once engaged, the towline 416 can be drawn in the direction indicated to draw the diver onto the distal end of the slide member 408 and up a sliding surface of the slide member, into the boat 400.

[00045] FIG. 5 shows a side elevation schematic diagram of another embodiment of a portion of a passenger deployment/retrieval system 507. A distal end or outer edge 517 of the slide 508 that extends into the water during deployment can be treated or otherwise outfitted with one or more features. For example, the outer edge 517 of the slide 508 can include a safety feature, such as having a rounded edge 521 or profile. Materials can be chosen for the end or outer edge 517 of slide 508 to further promote safety and comfort. For example, the end or outer edge 517 of the slide 508 can be treated or otherwise formed of a relatively soft flexible material 521.

Examples of such materials can include, without limitation, rubber, foam rubber, plastics, gels, fabrics and so forth. Such end treatments 521 serve to protect divers in the water as they approach the slide 508 for retrieval into a boat. Such end treatments 521 can also serve to protect passengers from within an interior portion of the boat, e.g., when the slide is in a stowed position. A blunt, rounded and/or soft end portion 521 does not pose a hazard for passengers within the boat.

[00046] In at least some embodiments, one or more weights 523 are attached to or otherwise incorporated into the slide 508. The weights 523 can serve to retain the slide 508 in a preferred proximity to a surface of the water. For example, the weights 523 can promote submerging of the distal end 517 during deployment. Preferably, the weights 523 alone or in combination with other features can promote a neutral buoyancy of the distal end of the slide 508 slightly below the waterline. Such neutral buoyancy acts to retain the distal end of the slide 508 at a relatively constant depth during deployment to present a consistent position of the mounting surface. Such consistency in positioning of the mounting surface, e.g., the distal end of the slide 508, promotes safety by removing injury hazards that would otherwise occur with a mounting surface that shifts in elevations, e.g., due to relative motions of the water surface and the boat.

[00047] FIGs. 6 A and 6B are, respectively, top and bottom views of an embodiment of a slide assembly 607 of a passenger deployment/retrieval system. An inclined sliding surface 629 of a slide 608 can include a relatively low friction treatment. Such treatments can include one or more of polishing, painting or glazing, and application of an attachable surface layer or laminate, either alone or in combination. Low friction materials can include fiberglass, plastics, woods, metals, ceramics, porcelains, non-stick surfaces, such as polytetrafluoroethylene (PTFE), e.g., Teflon®, paints and the like.

[00048] In the illustrative example two hinges 622a, 622b are shown positioned at a proximal end 627 of the slide 608 that abuts the interior portion of the boat. Along a distal end 617 of the slide 608 extending away from the interior portion of the boat other treatments and/or components can be included to provide various performance advantages. For example one or more weight elements 625a, 625b (generally 625), such as metals, e.g., lead can be provided to control a buoyancy of the slide 608. Alternatively or in addition one or more float elements 623a, 623b (generally 623), such as foams, plastics, hollow cavities, and the like can be formed within or otherwise attached to the underside of the inclined sliding surface to further control buoyancy.

[00049] In at least some embodiments, the slide 608 includes one or more through apertures extending from the sliding surface 629 to a bottom surface 631. In the illustrative embodiment, the slide 608 includes an array of aperture disposed towards a proximal end of the slide. The apertures 635 can allow a current of the water to pass through that portion of the slide 608 extending below the waterline, without applying an undue force on the slide 608. The apertures 635 can be confined to that portion of the slide expected to be below the waterline, e.g., the lower quarter portion.

Alternatively or in addition, such apertures can be provided over a greater area up to and including the entire sliding surface 629. The apertures 635 generally result in a lighter slide 608 facilitating operation between a stowed and deployed positions. Generally, care should be taken with any apertures to provide a smoothed or otherwise rounded profile to avoid unnecessary friction or binding to passengers moving along the slide 608.

[00050] In at least some examples buoyancy can be controlled such that the end of the inclined sliding surface extends slightly below the surface of the water at substantially all times when deployed. Such positioning allows a passenger approaching from within the water to align himself/herself with the top surface of the inclined sliding surface without having to lift his/her body out of the water. Such controlled buoyancy can be combined with hinges that allow flexing along the abutting edges between be inclined sliding surface and the platform and/or deck of the boat. The as the deck or platform of the boat moves relative to the surface of the water, e.g., during surface swells or ripples, the end of the inclined plane remains at a preferred position on or slightly under the surface of the water. The angle Θ as shown in FIGs. 2B and 4 would naturally change in such an arrangement.

[00051] FIGs. 7A through 7E are, respectively side elevation views of various stages of deployment of a diver 702 from a boat 700 into the water 710 according to an embodiment of a passenger deployment retrieval system. FIG. 7A shows a diver 702 seated on a platform 714 from a position within an interior portion of the boat 700, while the slide 708 is deployed extending away from the boat 700 and into the water 710. FIG. 7B shows the diver 702 positioned at an upper end of the slide 708 with a body alignment to promote sliding along a sliding surface of the slide 708 from the interior of the boat 700 and into the water 710. FIG. 7C shows the diver 702 in a position sliding along the sliding surface of the slide 708. FIG. 7D shows the diver 702 entering the water 710 along the slide 708. FIG. 7E shows the diver 702 within the water 710 after having been successfully deployed from the boat 700.

[00052] FIGs. 8 A through 8E are, respectively side elevation views of various stages of retrieval of a diver 702 from the water and into the boat 700 according to an embodiment of a passenger deployment retrieval system. FIG. 8A shows the diver 702 approaching the slide 708, from a position within the water 710, an end of the slide 708 at the surface of the water 710. FIG. 8B shows the diver 702 after having attached himself/herself to a towline 716 and position his/her body for sliding along a sliding surface of the slide 708 from the water 710 and into the boat 700. FIG. 8C shows the diver 702 being drawn by the towline 716 up the incline sliding surface from the water 710 towards the interior portion of the boat 700. FIG. 8D shows the diver 702 at least partially onto the platform 714 within the interior portion of the boat 700. Space FIG. 8E shows the diver 702 safely within the interior portion of the boat 700 and detached or otherwise removed from the towline 716. [00053] FIG. 9A is schematic diagrams of one embodiment of a passenger harnesses assembly 800a usable during retrieval of a diver from the water using the passenger deployment/retrieval system. In the illustrative embodiment, the harness assembly 800a includes two loops 802a' , 802a" (generally 802a) or rings are positioned at opposing ends of an elongated frame member 804a. The elongated frame member 804a can include a coupling 806a, e.g., at a midsection of the frame member 804a, between the two loops 802a. The coupling 806a can be used to attach the passenger harness 800a to an end of the towline 816a. In operation a diver can position their arms through the rings 802a. The rings 802a can be flexible, e.g., fabric, leather, rope, plastic, rubber and the like. Alternatively the rings 802a can be rigid, e.g., wood, metal, plastic, fiberglass, ceramic. In at least some embodiments, the rings can be padded, e.g., having a soft coating, such as a foam or foam rubber, applied to a rigid and/or semi-rigid ringed substrate. When the towline 816a is drawn into a boat the diver is drawn comfortably along an inclined sliding surface, being carried upward by the rings 802a. When safely within an interior portion of the boat, the diver removes his/her arms from the rings 802a in order to detach from towline 816a.

[00054] FIG. 9B is schematic diagrams of another embodiment of a passenger harnesses 802b usable during retrieval of a diver from the water using the passenger deployment retrieval system. In the illustrative embodiment two hooked members 802b' , 802b" (generally 802b) are positioned at opposing end of an elongated frame member 804b. The elongated frame member 804b includes a coupling 806b, e.g., at its midsection, between the two hook members 802b. The coupling 806b can be used to attach the passenger harness 800b to an end of the towline 816b. In operation, a diver can position his/her arms into the open areas of the hook members 802b, for example, engaging the hooks 802b under his/her arms, or at their elbows. When the towline 816b is drawn into the boat the diver is drawn comfortably along the incline sliding surface by the hooks 802b. When safely within the interior portion of the boat, the passenger removes his/her arms from the interior regions of the hook members 802b to detach from towline. [00055] FIG. 9C is a schematic diagram of yet another embodiment of a passenger harnesses 802c usable during retrieval of a diver from the water using the passenger deployment/retrieval system. In the illustrative embodiment an elongated frame member 804c includes a handle portion 802c, as in a handle of a water ski towline. The handle 802c is supported by the frame member 804c and attached to a coupling 806c at the midsection, e.g., to form a triangular structure, as shown. The coupling 806c can be used to attach the passenger harness 800c to the towline 816. In operation a diver can grasp onto the handle 802c with his/her hands, arms, legs, feet, etc.. When the towline 816c is drawn into the boat the diver is drawn comfortably along the incline sliding surface by the handle 802c. When safely within the interior portion of the boat, the passenger simply releases the handle 802c to detach from towline 816c.

[00056] FIG. 9D is schematic diagram of yet another embodiment of a passenger harnesses 800d usable during retrieval of a diver from the water using the passenger deployment retrieval system. In the illustrative embodiment, the passenger harness 800d includes a wearable vest assembly 810d. The wearable vest assembly 810d includes a coupling 806d that can be used to attach the passenger harness 800d to a towline 816d. The coupling 806d can be a quick release coupling 807d. In operation a diver wearing the vest assembly 810d can be attached to the towline 916d. When the towline 816d is drawn into the boat the diver is drawn comfortably along the incline sliding surface by the vest assembly 810d. When safely within the interior portion of the boat, the diver simply removes the vest assembly 810d to detach from towline. In some embodiments, the vest assembly 810d includes one or more fasteners or clasps 814d to enclose the vest assembly 810d about the diver's upper body.

[00057] It is understood that certain configurations of the passenger deployment and retrieval systems are configured for high volume and/or rapid deployment and/or retrieval of multiple divers. In some embodiments, the various slides 108, 308, 408, 508, 608, 708 disclosed herein can be dimensioned or otherwise sized to

accommodate more than one passenger at a time. For example, any of the various slides can extend for a width between the proximal and distal ends that is sufficient to accommodate more than one diver traversing the slide at the same time, e.g., double wide, triple wide, and so forth.

[00058] Alternatively or in addition, it is also understood that the various harness portions and/or towlines disclosed herein can be configured to accommodate multiple passengers at the same time. For example, multiple towlines can be used, one for each passenger. In other embodiments, one towline can be used to accommodate multiple divers at the same time. Referring next to FIG. 9E, a serial harness assembly 900a is shown in which more than one harness assemblies 902a are fastened or otherwise attached at different lengths along a common towline 916a. In the illustrative embodiment, each harness 902a' , 902a" has a respective coupling 906a', 906a" coupled at its respective position along the towline 916a. In a like manner, additional harnesses can be attached at other lengths along the towline 916a.

Although a triangular harness 902a is shown, it should be understood that any of the harnesses disclosed herein or equivalent thereto can be used. At least some of the harnesses can differ from others in one or more of size, shape, configuration, material, and the like.

[00059] FIG. 9F illustrates a parallel or shunt harness assembly 900b in which more than one harness assemblies 902b' , 902b" are fastened or otherwise attached at a common length along a towline 916b. In the illustrative embodiment, each harness 902b' , 902b" has a respective coupling 906b' , 906b" coupled at its respective position along the towline 916b. The harness assembly 900b includes a spacer or separator, such as an elongated frame member 905b having a longitudinal axis that is transvers to the towline 916b. The first harness 902b' is attached to one end of the elongated frame member 905b by way of the respective coupling 906b' . Likewise, the second harness 902b" is attached to another end of the frame member 905b by way of the respective coupling 906b". In a like manner, additional harnesses can be attached at other positions along the frame member 905. Although a triangular harness 902b is shown, it should be understood that any of the harnesses disclosed herein or equivalent thereto can be used. At least some of the harnesses can differ from others in one or more of size, shape, configuration, material, and the like. In at least some embodiments, one or more of the serial harness assemblies can be combined with the shunt harness assemblies in a composite harness assembly.

[00060] FIG. 10 is a planar view of a boat 1000 deploying a number of divers 1002 to support a community diving event. Beneficially, the passenger deployment and retrieval systems and techniques disclosed herein allow for rapid, non-traumatic deployment of any number of divers 1002 from an interior portion of a boat 1000 into the water, and rapid, non- traumatic retrieval of those returning divers 1002 from the water into the interior portion of the boat 1000. Such rapid deployment and retrieval of divers 1002 can be beneficial for relatively large numbers or groups of passengers, such as excursion groups for group diving and/or snorkeling events. In the illustrative embodiment the group dive uses a common mechanically assisted air delivery mechanism 1010. Such a mechanism can be positioned in a flotation device 1012, such as inflatable raft, providing breathable air into a number of hoses 1014 outfitted with breathable regulators 1016 to allow divers 1002, including inexperienced divers 1002 to enjoy a diving experience without the need for scuba training or certification.

[00061] In at least some embodiments, construction of the water vehicle is relatively simple and relatively easy to operate, thereby allowing for a scalable, cost effective operation. In some instances it can be applied to existing boats by way of a retrofit kit. Namely, the upfront investment costs for an excursion operator are not excessive. The vessel can be operated with sufficient numbers of passengers to keep the cost-per-passenger at an acceptable value compared to other excursions, and additional vessels can be procured as needed, depending upon demand.
