Systems for stowing and deploying an accessory on a watercraft are provided. More particularly, systems for providing watercraft, such as pontoon boats (or other watercraft), with deployment mechanisms for deploying marine accessories are provided. Such accessories can be deployed from a recessed location, such as a compartment within or underneath a deck of the watercraft.

A diving equipment organizing apparatus having a housing assembly with a sidewall that extends from a top edge to an end. The end inserts into an aperture that typically serves as a rod holder of a watercraft. A frame assembly has a frame having at least one base connector. Further having a strap assembly, a basket, and at least one hook assembly. The housing assembly further has a hinge assembly having a lower connector, an upper connector, and an actuator. The actuator is rotated to unlock the hinge assembly to permit angling the upper connector to a desired angle with respect to the lower connector. The housing assembly defines a cavity and the end has at least one notch.

A securing assembly is adapted to secure objects to a structure. The assembly includes an attachment mechanism adapted to attach the assembly to an object in use. An elongate rod has a first end and a second end, wherein the first end is connectable to the attachment mechanism and the second end is connectable to an adjustment device. A base is adapted to connect the adjustment device to the structure in use. The adjustment device is operable to adjust a tension between the object and the structure by way of the assembly to secure the object to the structure in use.

A captive beam system is provided. The system includes a beam assembly comprising a beam and channel units at each end. The beam comprising a top surface that, when the captive beam system is installed, faces upward, wherein the top surface establishes a flat resting surface. Each channel unit supports a bracket and a pawl, the pawl is rotatable with respect to the first end of the channel unit. The pawl comprises a support surface that is configured, when the captive beam system is installed, to rest upon a bottom edge of an aperture disposed within a fixed track, wherein a vertical distance between the support surface and the flat resting surface of the beam is about 2.58 inches. An optional upper latch is configured to substantially prevent movement of the beam assembly in a direction along a long axis of an aperture of a fixed track.

A watercraft is provided with a watercraft body and a storage container. The watercraft body includes a hull and a deck. The deck is provided on the hull. The storage container is attached to the watercraft body. The storage container includes an access opening and an annular sidewall. The access opening opens upward relative to the deck. The annular sidewall has an upper end, a lower end and an interior storage space between the upper end and the lower end. The lower end of the annular sidewall defines a bottom opening with a cross sectional area that is larger than a cross sectional area of the upper end of the annular sidewall.

A water-propelled or water-powered unmanned aerial vehicle including a base configured to carry a payload, and at least one nozzle attached thereto. The at least one nozzle is configured to selectively receive pressurized fluid from a source located remotely from the vehicle. The vehicle includes a control system configured to alter or otherwise selectively dictate the flow of fluid through the at least one nozzle and/or the orientation of the at least one nozzle with respect to the base in response to a received control signal for providing controlled unmanned vehicle flight.

A marine hub attaches to a boat pedestal, dock support or other vertical support post, and has removable interchangeable attachment arms that radiate from a main body tube or disk that fits around the support post. The main body tube has a bore with an inside diameter just larger than the diameter of the support post. An adapter ring may be used within the bore of the main body tube for mounting on posts that are smaller, or not cylindrical. Support stub members radiate from the main body tube, and the attachment arms secure to these with quick release pins. The support arms may be used with fishing or boating accessories, beverage holders, or other equipment.

An elevation system includes deck units each including a frame, a movable deck coupled to the frame to be movable in a vertical direction, a sliding unit coupled to the frame to be movable in a horizontal direction, and elevation wires connected to the movable deck and the sliding unit via a direction changing sheave at the frame, a first sheave at each of the deck units and fixed to the frame, a second sheave at each of the deck units and coupled to the sliding unit to adjust a distance between the first sheave and the second sheave, a drive wire extending through the deck units and simultaneously wound around the first sheave and the second sheave of each of the deck units to deliver a driving force to the sliding unit, and a driver pulling the drive wire to cause the sliding unit to be slidably moved.

An underwater base for handling plural underwater vehicles equipped with seismic sensors for recording seismic signals during a marine seismic survey. The underwater base including a storing part configured to store the plural underwater vehicles; an inlet part located above the storing part and configured to control access of the plural underwater vehicles to the storing part; a control part configured to acoustically guide the plural underwater vehicles to the inlet part; and a support part configured to support the control part, the storing part and the inlet part. The storing part is further configured to receive the plural underwater vehicles as the plural underwater vehicles fall from the inlet part into the storing part.

A height adjustable rack apparatus for Jon boats and the like includes a plurality of brackets attached to a boat gunwale, vertical supports extending from the base that are pivotally operable, and a pivotally adjustable rack apparatus supported by the vertical supports. There is no need for screws or clamps to attach the rack to the boat's gunwale. This apparatus is mainly used for duck hunting and fishing.
