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 shore-engaging spike rotation mechanism which allows a user to move the water vessel further up the shore or alternatively away from the shore.
Claims5
A door system for a boat, the door 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 substantially planar bow ramp having a proximal end pivotably attached to the hull at a bow ramp/hull pivot, and a distal end;
- a user-actuated bow ramp lift mechanism attached between the bow ramp and the hull configured to mechanically manipulate the bow ramp about the bow ramp pivot from a closed position to an open position;
- at least one shore-engaging spike pivotably attached to the bow ramp at a bow ramp/spike pivot near the distal end of the bow ramp;
- a user-actuated shore-engaging spike rotation mechanism separate from the user-actuated bow ramp lift mechanism, the user actuated shore-engaging spike rotation mechanism configured to mechanically manipulate the user actuated shore-engaging spike about the bow ramp/spike pivot;
- and
- a remote control actuator for each of the user-actuated bow ramp lift mechanism and the user-actuated shore-engaging spike rotation mechanism.
