A watercraft comprising a hull, a roof, a support including a first end coupled to the roof and a second end positioned within the hull, and an actuation assembly coupled to the support. The support is moveable between a first position and a second position in response to activation of the actuation assembly. The support extends into the hull a first distance in the first position and a second distance in the second position. The second distance is larger than the first distance.

A foldable watersports tower for a boat includes a pair of legs configured to mount to the boat, at least one leg actuator operable to move the legs between a raised configuration and a lowered configuration, a cross-piece extending between the legs, a roof operably mounted to the legs, and a roof actuator operable to move the roof with respect to the pair of legs, wherein the at least one leg actuator and the roof actuator are configured such that the roof maintains a substantial contact attitude as the pair of legs are moved between the upright and the lowered configurations.

Described herein are watercraft comprising a hull comprising a first hull assembly, and a second hull assembly opposite the first hull assembly and parallel to the first hull assembly; and a frame configured to couple the first hull assembly to the second hull assembly. In some embodiments, the first hull assembly comprises a first quarter hull coupled to a second quarter hull, and the second hull assembly comprises a third quarter hull coupled to a fourth quarter hull. In some embodiments, the first and third quarter hulls are substantially reflectively duplicative of the second and fourth quarter hulls. In some embodiments, the first hull assembly is substantially reflectively symmetrical to the second hull assembly. Various embodiments may further include a roof comprising one or more energy harvesting arrays thereon. The roof may be movable, in various embodiments, between a closed configuration and an open configuration.

An apparatus (100), including: a support assembly (200), the support assembly including: a lower endcap (240), an upper endcap (252), a strut (242), a lower pivot joint (244) between the lower endcap and a lower end (248) of the strut, and an upper pivot joint (254) between the upper endcap and an upper end of the strut (246). The support assembly is configured to selectively move an upper structure (400) relative to a motor vehicle (500) between an upper position via rotation at each pivot joint which increases a distance (270) between respective endcap centroids (272, 274), and a lower position via rotation in an opposite direction at each pivot joint which decreases the distance (276) between the respective endcap centroids.

A boat tower and cover arrangement includes a boat tower assembly that includes a pair of frames each having a pair of side frame portions and a cross-frame portion and an intermediate frame member extending between one of the side frame portions of the first frame and one of the side frame portions of the second frame and defining an interior space, a cover assembly that includes a cover frame member movable between first and second positions, and a cover operably coupled to the cover frame member, and a drive arrangement that includes an actuator including a motor operably coupled to the cover frame member for moving the cover frame member between the first and second positions, wherein at least a portion of the motor is located within the interior space of the first intermediate frame member.
