Document Type and Number:
Japanese Patent JP3115613
Kind Code:
B2
Abstract:
The boat has a flap (1) forming a part of its V- or spoon-shaped bow and being unfoldable therefrom. This flap is supported by means of projections (9a,9b) arranged on both of its sides on swivel joints (13a,13b) set back into the inside of the boat with respect to the inner wall of the bow. Upon pivoting the flap (1) out of the bow opening (15), the flap is swung away from the bow wall portion with the uncovering of an interspace (2) between the flap and the bow wall portion which latter lies underneath the bow opening (15). The flap outside wall can be urged underneath the surface of the water and can be fixed in its position. The flap (1) is designed as a buoyant member, and when serving as a working or recreational platform, etc., can be folded back into the bow of the boat in such a way that the hydro- and aerodynamic properties as well as the esthetic appearance of the bow are not impaired. The boat according to this invention can thus be utilized, without restriction of its full functional ability, as a rescue boat, salvage boat, pleasure boat, and speedboat. The configuration of the flap (1) acting as a buoyant member makes its use possible without impairing the stability of the boat; in the unfolded condition, this configuration even enhances the capsizing stability of the boat. Furthermore, the design of the boat hull is such that the stern engines, when a curve is traversed, do not leave the water (4), and the boat exhibits a very high capsizing stability.
