Abstract: A vessel having an elongate base frame with a transverse tubular member adjacent each end of said base frame. The vessel also has elongate buoyancy members extending substantially parallel to a longitudinal axis of the base frame adjacent opposite sides thereof. The elongate buoyancy members are movable between respective extended and retracted positions relative to the base frame by support beams telescopically located within respective ends of a respective tubular member. The vessel also has a drive system to selectively move the elongate buoyancy members between the extended and retracted positions. The vessel also has a mobile transportation unit. The transportation unit includes an elevation mechanism to move the vessel between a raised position with retracted buoyancy members for road transportation and a lowered position with extended buoyancy members. The mobile transportation unit is detachable from the vessel when in the lowered position.
