A multihull variable aspect surf rescue boat comprises four component assemblies to form a modular component system comprising:
1. structural tubular frame chassis and frame payload platform that support and contain occupant(s) and cargo,2. plurality of adjustable modular flotation control assemblies that control the vessel's buoyancy and steerage,3. plurality of telescoping tube strut assemblies that vary the vessel's overall length to beam ratio and control the craft's attitude, center of buoyancy and center of gravity,4. propulsion and control assembly to propel and guide the vessel.;Component assemblies 1, 2 and 3 are constructed to minimize the vessel's wetted surface subject to lifting and rotation forces of waves and reduces the skin friction and water resistance. Component 2 provides the operator with improved control of buoyancy. Component 3 provides the operator improved control of the surf rescue boat's geometry, center of buoyancy and center of gravity. |

1. Variable aspect surf rescue boat comprising:
a) a main body having a chassis and frame made of multiple tubes and frames, each secured to an adjoining assembly with tubes that lock into a position relative thereto with chassis receiving tubes radiating from the chassis centerline thereby transferring loads and forces between the adjustable tube strut assemblies, the propulsion and control assembly, the payload platform assembly, and the flotation starling control assemblies. b) a plurality of adjustable tube strut assemblies, each having at least one first member tube with a proximal end and a distal end forming a length there between, said proximal end securable to a flotation control assembly or a chassis receiving tube; and having at least one second member tube having a proximal end and a distal end, said proximal end that may manually be inserted into said first member tube so that the assembly may extend or retract independently to vary the invention's length overall to beam on center ratio (OAR); and having a locking mechanism at either end, c) a plurality of modular adjustable flotation starling control assemblies, each flotation control assembly having at least one flotation starling hull with one or more internal voids and watertight tubular penetrations for the insertion of flotation starling control riser posts that fit snugly inside the flotation starling tubular penetrations held in place by a top and bottom control plate, control riser post, control riser top and keel plate and a tube strut control bracket in such a way as to lock said starlings, plates, posts and flanges together as a unified whole. d) a propulsion and control assembly having one or more parallel rails rail mounted on trestle posts that connect to the chassis and frame payload platform assembly upon which ride carry at least two wheeled trucks each having a locking slot and pin to selectively immobilize one or both trucks upon which are mounted at least one seat and one oar rig component. |
