Abstract
Disclosed herein is a bow ramp for a water vessel (boat) wherein the bow ramp is configured to rotate/pivot to an open position to allow passage from within a hull of the vessel to a shore. The bow ramp is operated in combination with shore penetrating spikes which penetrate a shore or seabed (riverbed, lakebed, etc.) and include a user-actuated spike rotation mechanism which allows a user to move the water vessel further up a shore or alternatively away from a shore.
Claims5
A door system for a boat, the system comprising:
- a vessel having a hull configured to float on the surface of water, the hull comprising a bow and a stern;
- the bow having a bow ramp having:
- a proximal end pivotably attached to the hull at a bow ramp/hull pivot, and a distal end having a bow ramp/spike pivot adjacent thereto;
- a user-actuated bow ramp lift mechanism connected between the bow ramp and the hull, the bow ramp lift mechanism configured to mechanically manipulate the bow ramp about the bow ramp pivot from a closed position to an open position, to mechanically exert force upon the bow ramp in an upward and in a downward direction;
- at least one spike pivotably attached to the bow ramp at the bow ramp/spike pivot;
- a user-actuated spike rotation mechanism independently operable from the bow ramp lift mechanism, the spike rotation mechanism configured to mechanically manipulate the spike about the bow ramp/spike pivot in a forward and in a rearward direction;
- and
- a remote control actuator for each of the user-actuated bow ramp lift mechanism and the user-actuated spike rotation mechanism.
