ROWING-SAIL MOTORBOAT Russian patent published in 2020 - IPC B63B35/71 

FIELD: shipbuilding.

SUBSTANCE: invention relates to small-size shipbuilding, namely for sport, tourism, rolling stations, ship boats, patrol, rescue and transport vehicles. Rowing-sail motorboat comprises hull, paddles, transverse bulkhead, anchors, abbreviated spaces, filled with foam plastic, for engine plate, in the wide displacement hull the central keel-ski is inserted with a pull-out relative to inscribed board keels-skis so that these keels-skis are connected in single-hull vessel of ovoid shape. On axes with shock-absorbing elements to outer walls of side keels-skis there are skid carriages, at the beginning of central keel-ski, rudder-shoe, and in ends of side keels-skis hingedly flaps with brake pads in end. Said armament is three-staysail: nose staysail and two side staysails with common boom on swinging mast in form of swinging academic paddle installed in steppe on deckhouse roof and pipe to which pilot seat is fixed on yoke with possibility of rotation, and in the middle part of this pipe there is a smoke fume tube with a plate suspended to it for cooking of boiling water, food and heating, besides, on the upper part of the pipe on the clamp hingedly installed are the rear and front hatches of the cabin with possibility of rotation in vertical and horizontal planes with sail trimmer wiring with ends of hatches on top of pipe. Steering wheel of aviation type is installed on axis of rudder-skate by means of coiled spring with possibility of deviation to itself, from left, to right and turn to the left and to the right and is connected by means of rope wiring with flaps of side keels-skis and rotary motors in recession. Pneumatic wheels are installed on their studs in threaded holes in walls of shutter-rudders of rudder-skate in pairs, cantilever. Hull is equipped with a fodder attachment with longitudinal transverses, and the fore part – nozzle, on which there is a detachable anchor with a trailing standard connector to the car, at the same time two wheels are fixed on the water to the fodder implements at the level of longitudinal crosswise lines.

EFFECT: higher speed, protection of fore part from mechanical effects, higher, seaworthiness, stability, water quality, habitability, finishing motor-cycle in trailer with anchor, eliminating splashing of rower during rowing with double-bladed paddle in wide and high-flying boat.
