SMALL-SIZED HIGH-SPEED TWO-SEATED BOAT-HYDROCYCLE Russian patent published in 2005 - IPC

FIELD: shipbuilding; recreation and sports craft.

SUBSTANCE: proposed boat-hydrocycle has hull, reversible steering gear and motion control unit connected with engine and with reversible steering gear; driver and passenger seats are located on either side from CL at level close to WL. Boat-hydrocycle control unit is located between seats and is made in form of joy stick kinematically connected with rudder and with control system kinematically coupling the engine and reversible gear control. Control system is made in such form that when joy stick is inclined to "forward" from neutral position, reversible gear is shifted to "ahead running" position and engine revolutions increase in proportion to shift of joy stick and when joy stick is inclined to "sternward" from neutral position, reversible gear is shifted to "astern running" position and revolutions of engine increase also in proportion to shift of joy stick; joy stick is so connected with rudder that when it is inclined to one side, boat-hydrocycle turns to the same side and vice versa.

EFFECT: enhanced seaworthiness of boat; enhanced stability at abrupt maneuvers; possibility of performing abrupt dynamic braking due to use of reversal mode.
