A system for attaching accessories to a boat that is moveable between a first, stored configuration and a second, expanded configuration. The system includes a boat, a first leg frame member, a second leg frame member, an attachment device, a first support member, and a second support member. The first leg frame member has a proximal first end attached to the boat such that a portion of the first leg frame member is pivotable relative to the boat. The second leg frame member has a proximal second end attached to the boat such that a portion of the second leg frame member is pivotable relative to the boat. The attachment device is mounted to the first leg frame member and the second leg frame member. The first support member is attached to the first leg frame member and the second support member is attached to the second leg frame member.

The present invention comprises a device for acting on water flow as a watercraft moves through the water. The device is generally comprised of a primary plate having two downward angled tabs and a handle. Device is installed on the stern of watercraft, preferably engaged to a prior art ladder. The angular tabs and primary plate delay a portion of the wake from reaching the surface of the water, thereby allowing time for the converging water flow from either side of the watercraft to merge more seamlessly with the wake. This convergence creates a more laminar surf wave.

A boat including first and second seats. The first seat has a first seating surface. The second seat has a second seating surface. The second seating surface may be at a level higher than the first seating surface. The second seating surface may be moveable between a retracted position and at least one raised position.

A boat in which at least a portion of at least one of the port side and the starboard side of the hull is moveable between a first position and a second position. In the first position the moveable portion forms a generally upright portion of the port or starboard side of the hull, and, in the second position, the moveable portion forms a generally horizontal deck surface. A walkway connects a seating area within the boat to an area aft of the seating area, and at least a portion of the walkway is adjacent to the moveable portion of the port or starboard side. A first seat is positioned adjacent to at least a portion of the walkway and a removable seat is configured to be positioned over the walkway and adjacent to the first seat.

The present invention relates to a submersible stern platform (100) equipped with openings for recreation, comprising an opening (150), one or more secondary openings (160) preferably arranged along the vicinity of the opening (150), the opening (150) being reversibly closed by a gate (151) and the secondary openings (160) being reversibly closed by one or more secondary gates (161).

The present invention relates to a stern platform (100) provided with recreation openings, comprising an opening (150) arranged in any position on the platform (100), comprising at least one gate (200) provided with at least one removable element (210) and/or at least one foldable element (220).

A watercraft with a hull assembly and a mat storage system coupled to the hull assembly. The hull assembly may have a mat compartment with the mat storage system configured to move the mat between a stored position, in which at least a portion of the mat is positioned in the mat compartment, and a deployed position. The mat compartment may be positioned beneath at least a portion of a floor of the hull assembly. The hull assembly may have a cover positioned adjacent the mat compartment and moveable between a closed position, in which it covers at least a portion of the mat compartment, and an open position. The mat storage system may have a motor that is configured to move the mat to a stored position.

A movable platform assembly for a boat includes a support structure configured to be connected to the boat, a platform, and a horizontal translation system connecting the platform to the support structure, the horizontal translation system having a pair of main arms rotatable about respective vertical rotation axes, and a pair of main sliders sliding in a transverse direction along a main guide integral with the platform. Each main arm has a proximal end hinged to the support structure and a distal end hinged to a respective main slider. The platform is translatable between a retracted position and an extended position with respect to the support structure.

Sun heats dark continents more than reflective oceans. Air moves onshore from high pressure to low. Creating wind: powering weather and storms—“hurricane-in-a-box-on-water” principles producing electricity in a marine vessel, providing Green Technology for Marine Transportation. Captured and recovered heat, offset by loss of heat, creates differential pressure conditions across multiple rotary engines. Night and day, a working fluid moves from high pressure to low; powering alternators, batteries, domestics, and in-hull electric drive trains, in a unique, lightweight exoskeleton dome shell design vessel. Disclosed vessel design advantages include: high energy collection and living space to vessel length ratio; high strength to weight ratio; high carrying capacity, downwind sailing while producing electricity; modular fabrication and shipping; and sustained hull speed in a vessel harvesting energy from the environment. The longer the vessel: the more it carries: the greater the hull speed: the faster it goes.

Disclosed embodiments provide an apparatus having a submersible seating surface attached to a watercraft. The submersible seating surface may be raised to serve as a table when not in use as a seat. A tension member provides upward force on the seat, allowing it to be easily raised from a lowered position to a raised position. In some embodiments, a tether is used to provide additional security for the apparatus. In embodiments, a hydrofoil cup holder is affixed to the seat to provide additional lift when a watercraft is moving forward, urging the seat upward and out of the water. The hydrofoil cup holder further includes an opening in a top surface of the cup holder to secure an item such as a beverage container. Embodiments may further include a submerged safety indicator to alert nearby swimmers and/or people on the watercraft of the submerged seat.
