[0025] In one embodiment, the body is composed of a corrugated paper-based material including multiple corrugated flutes. In one embodiment, one or more gaps disposed between the multiple flutes may be filled with a pulp material. In one embodiment, the pulp material is made up of paper residue (e.g., paper dust or shavings) that results from the machining, cutting, or other processing of the surfboard template. In one embodiment, the pulp may include the paper residue combined with a water-resistant paper coating.

Advantageously, the introduction of the pulp into the body serves to fortify and strengthen the materials of the corresponding surfboard template.

[0026] In one embodiment, a surfboard template includes a ring-shaped frame including multiple layers or sheets of corrugated paper. In one embodiment, a first layer (or set of sheets) are arranged to create a first extended portion or surface. A body including an extended portion or arm may be arranged such that the extended portion (or step portion) of the body is disposed on the extended portion of the first layer of frame. In one embodiment, the body is nested into the first layer of the frame such that the one or more step portions of the body is disposed on corresponding extended portions of the first layer of the frame. In one embodiment, a second layer of the frame is disposed on the body and the first layer of the frame, such that the extended portion of the body is stacked or sandwiched between the first and second layers of the frame.

As shown in Figure 4A, the frame 410 may include a first set of layers (or sheets) 413 arranged to form first stepped portion 413A. In one embodiment, the body 420 may be disposed or nested within an inner cavity of the frame 410 such that a portion of the body 420 (e.g., the extended portion shown in Figure 4A) is disposed on the first stepped portion 413 A of the frame 410.

[0033] As shown in Figure 4B, a second set of layers (or sheets) 414 of the frame 410 may be arranged such that second stepped portion 414 is disposed on top of the extended portion of the body 420. In one embodiment the first layer and the second layer of the frame 410 sandwich at least one extended portion of the body 420 to couple the body 420 in place within the frame 410. In one embodiment, the frame 410 may include multiple sections or stackable layers (e.g., the first layer 413 and the second layer 414) that may be arranged to sandwich or secure one or more extended portions of the body 420 between the layers or stacks. In one embodiment, the multiple layers of the frame 410 may be coupled to one another using any suitable approach, such as bonding, gluing, etc.

[0034] In one embodiment, the watercraft template 400 may be finished and laminated as used as a blank for fabricating a watercraft board according to desired specifications. Advantageously, the watercraft template 400 may be completely composed of sustainable recyclable paper having desired rocker specifications added during the coupling or bonding process.

In one embodiment, the portions 722A, 722B of the body 720 are folded or otherwise arranged to enclose the frame 710 within the body.

[0038] Figure 8 illustrates a side view of an example watercraft template 800 including a frame 810 enclosed within a body 820, according to embodiments of the present disclosure. In one embodiment, the watercraft template 800 may be fabricated according to the steps describes above with respect to Figures 6 A, 6B, 7A, and 7B. In one embodiment, the rolled frame 810 may be further processed (e.g., sanded, machined, etc.) to have an outer rail according to desired specifications associated with a watercraft board.

[0039] According to embodiments of the present disclosure, a sandwiched assembled frame and body create a watercraft template or blank that is an alternative to foam blanks, and can be machined and processed to form a watercraft board. In one embodiment, the watercraft board (e.g., a surfboard) includes an outer rail portion fabricated according to the methods and techniques described herein. In one embodiment, a watercraft template and fabricated watercraft of the present disclosure allows a surfer to ride a board with a completely sustainable body or core that is comparable in strength and weight to industry standards. Advantageously, the watercraft template and resulting watercraft board are more sustainable and less toxic to the environment, and to the exposure of the machinist, as compared to conventional foam boards.

[0040] In implementation, the watercraft template includes a body composed of a paper-based material in a honeycomb configuration that enables the option of a transparent or see-through design that allows light to pass through the watercraft board. In one

embodiment, a watercraft template may be shaped using a sandwiched blank as an alternative to a foam core. In one embodiment, the watercraft template may be shaped either by hand or by a computer numerical control (CNC) shaping machine that machine shapes various details into the template. In one embodiment, in fabricating the watercraft board from the watercraft template, the watercraft board may be coated with a coating material, such as fiberglass resin or epoxy resin. In one embodiment, an additional center corrugated stringer may be added during fabrication of a watercraft board for rocker and stability. In one embodiment, a watercraft template fabricated in accordance with the description relating to Figures 1-8 may be used to design a watercraft board having any desired shape, thickness, and rail specifications.

[0041] It is to be understood that the above description is intended to be illustrative, and not restrictive. Many other implementations will be apparent to those of skill in the art upon reading and understanding the above description. The scope of the disclosure should, therefore, be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
