Patents Act 1990 COMPLETE SPECIFICATION INNOVATION PATENT BOAT BOW BOARDING LADDER The following statement is a full description of this invention, including the best method of performing it known to me:- 0 BOAT BOW BOARDING LADDER
O
Most conventional boat boarding ladders attach to the side or the rear of the boat. To allow a person to board the boat it is necessary for the side or rear of the boat to be presented to the landward side of the boat. This can create difficulties if it is necessary to keep the boat motor running to hold the boat against wind or current.
00 o The invention has been designed to provide a method of boarding the boat from the bow thus S allowing the propellor to remain in deeper water. The invention allows a person to disembark from the boat, e.g. when coming into a beach or boat ramp while still keeping the propellor in the deepest possible part of the water.
The invention is attached to the towing ring of the boat by means of a bolt or similar securing device and can be raised or lowered as required. In the lowered position the lower struts, which are bent to the configuration of the boat hull, sit snugly against the boat hull suitably protected by a rubber or similar cushioning material. The weight of the person using the ladder creates a downward thrust on the mounting ring, which is arguably the strongest part of the boat, countered by an upward pressure of the struts against the hull. Once aboard the ladder is raised to sit under the bow sprit and is secured in place by a rubber or similar retaining strap across the bow sprit or around the forward bollard.
The invention may be removed from the towing ring and stowed in the boat or may be left in place whilst the boat is underway. The protruding struts, when the boat is underway, have a negligible effect on hull performance. The mounting bracket at the towing ring may also include a towing ring or winching ring which allows the device to remain on the boat when being winched onto a trailer.
A roller may be incorporated at the centre of the lower rung of the ladder thus creating a bow sprit for a boat not supplied with one. As many or as few rungs may be added to the ladder as is necessary to allow convenient boarding.
The boat may be boarded from either the port or starboard side of the bow sprit.
The device eliminates the necessity for deck hardware thus relieving stress on the deck or bow rails as occurs with fixed deck mounted ladders or rope ladders. The invention can be made from stainless steel tube, however other materials or shapes may also be used. The struts may also be joined by a web material thus forming a cradle which sits against the leading edge of the bow when the ladder is down in the boarding position.
The invention may be better understood by reference to the illustrations of embodiments of the invention attached. Figure 1 is an elevation of the boat bow boarding ladder in its down boarding position. Figures 2 and 3 are elevations of the ladder in its up or stowed position.
Claims (2)
- 3. A boat boarding ladder which may be removed or retained in position whilst the boat is underway. 00
- 4. A boat boarding ladder which allows the boarding of a boat whilst maintaining 0 the boat propulsion device in the deepest possible part of the water and which allows the motor to continue to run without danger of injury from the propellor to persons boarding or disembarking the boat. A boat boarding ladder which attaches to one of the strongest parts of the boat thus relieving strain on more vulnerable mounting points on the boat. DANIEL JOHN McAULIFFE October 4, 2004
