The present invention relates to a winged boat comprising a main body including a passenger space and a closed space at an edge, buoyant wing parts protruding from both sides of the main body, disposed in a front and a rear area of the main body, and each including a wing body protruded from a side of the main body; a buoyant space formed inside the wing body in a closed state; a water storage part disposed in an opposite direction to the main body with respect to the buoyant space and having an opening and closing part at a lower portion and an inlet formed at an upper portion, and a buoyancy control part provided in an opposite direction to the buoyant space with respect to the water storage part and adjusting buoyancy of the wing body by controlling an amount of water stored therein.

An elliptical powered watercraft includes a buoyant platform, a paddle wheel, pedals operatively connected to the paddle wheel, and a skeg, a fin, or a rudder operatively connected to a steering device, such as handlebars or a steering wheel. An operator propels the elliptical powered watercraft by balancing on the buoyant platform, generating rotational movement with the pedals to deliver power to the paddle wheel, and steering the elliptical powered watercraft by turning the skeg, the fin, or the rudder with the handlebars or the steering wheel.

The drive module buoyancy body is either made as a solid material, inflatable or as a hollow body with inflatable air chambers inside, which includes a seat and a shaft mounted in a front portion and extending in a direction transverse to the longitudinal direction of the buoyancy body. Paddle wheels are mounted at the ends of the shaft. A profile is articulated to the shaft in its center so as to be able to pivot about its lower end region, which profile extends upwards from the shaft and in which a crankshaft with a drive wheel is mounted at the upper end region of the profile. The cranks of the crankshaft can be optionally equipped with pedals for a foot drive or crank handles for a hand drive. By driving the cranks, the paddle wheels are driven by a roller chain or a toothed belt, the profile (7) being able to be engaged in a pivoted position for foot drive and being able to be engaged in a position different therefrom for manual drive.

A drive module for submersible autonomous vehicles is disclosed. The drive module includes a propulsion element configured to engage and rotate against a surface, a motor configured to drive the propulsion element, and a controller configured to cause the motor to drive the propulsion element. The drive module also includes a housing configured to be removably, releasably coupled to the exterior of a submersible autonomous vehicle. The motor and the controller are disposed within the housing.
