Cycling Hull with Slow-Relative-Motion Hydrodynamics

Abstract

Device ( 1 ) creates slow-relative-motion hydrodynamics in a cycling hull ( 10 ) when multiplicity of hull sections ( 11 ) moves between multiplicity of rotatable end waterline turnabouts ( 20 ) and multiplicity of rotatable keel turnabouts ( 30 ). When device ( 1 ) moves across water, multiplicity of hull sections ( 11 ) cycles via connection to pivotable connection ( 12 ), which pivots about multiplicity of rotatable end waterline turnabouts ( 20 ) and multiplicity of rotatable keel turnabouts ( 30 ). This puts cycling hull ( 10 ) in motion. Since the bottom of multiplicity of rotatable keel turnabouts ( 30 ) is lower than the bottom of multiplicity of rotatable end waterline turnabouts ( 20 ), the portion of cycling hull ( 10 ) moving between multiplicity of rotatable end waterline turnabouts ( 20 ) and multiplicity of rotatable keel turnabouts ( 30 ) also travels the full draft of device ( 1 ). As there is no relative motion between the water and multiplicity of hull sections ( 11 ) as it cycles along the keel line set up between first keel turnabout with axle ( 31 ) and second keel turnabout with axle ( 32 ), so there is slow relative motion between the water and multiplicity of hull sections ( 11 ) as they cycle between multiplicity of rotatable end waterline turnabouts ( 20 ) and multiplicity of rotatable keel turnabouts ( 30 ). The slow relative motion can be quantified as the product of dividing the vertical distance between the waterline and the keel line by the horizontal distance between rotatable end waterline turnabouts ( 20 ) and rotatable keel turnabouts ( 30 ), which produces a percentage of the overall speed of device 1 as it moves across water.

I claim: 
     
         1 . A cycling hull with slow-relative-motion hydrodynamics, comprising:
 (a) a multiplicity of rotatable end waterline turnabouts having a first end waterline turnabout with axle and a second end waterline turnabout with axle,   (b) a multiplicity of rotatable keel turnabouts having a first keel turnabout with axle and a second keel turnabout with axle, said multiplicity of rotatable keel turnabouts being aligned horizontally with and inboard of said multiplicity of rotatable waterline turnabouts in a substantially vertical orientation with the bottom of said multiplicity of rotatable end waterline turnabouts being situated higher than the bottom of said multiplicity of rotatable keel turnabouts,   (c) a forked frame for securing said multiplicity of rotatable end waterline turnabouts and said multiplicity of rotatable keel turnabouts, and   (d) a cycling hull having a multiplicity of hull sections and a pivotable connection by means of which said multiplicity of hull sections can cycle about said multiplicity of rotatable end waterline turnabouts and said multiplicity of rotatable keel turnabouts,   
       whereby a cycling hull, while cycling across water, creates a gradual descent for its hull sections as they move from first water contact toward full draft placement at the keel line and a gradual ascent for its hull sections as they move from full draft placement at the keel line toward last contact with the water.
