A boat includes a dash positioned proximate a windshield at a first non-zero angle. A speaker is mounted under a top surface of the dash at a second non-zero angle. The speaker is positioned to direct sound emanating from the speaker through an opening in the dash and the windshield is configured to reflect the sound emanating from the speaker as reflected sound in an aft direction. The boat may also include an enclosure having a reflective surface positioned within a cavity formed between the deck and hull of the boat. A speaker, mounted within the enclosure, and the reflective surface are configured to reflect sound emanating from the speaker off of the reflective surface and through an opening of the enclosure.

Networkable digital life jackets and associated methods are disclosed. An example life jacket includes a state manager and a swarm manager. The state manager is configured to selectively operate the life jacket in one of multiple operational states of the life jacket based on data obtained from one or more sensors of the life jacket. The swarm manager is configured to form a swarm network including the life jacket and one or more other life jackets.

A recreational watercraft system of interconnectable, inflatable tubes that can incorporate a configurable frame that may be removably affixed at different vertical heights to attachment brackets that are axially strapped around the inflatable tubes. A plethora of accessories are available to accommodate, oars, paddles, masts, motors and the like, depending on what watercraft shape has been assembled. It can be assembled into a canoe, raft, motorboat, sailboat, fishing float etc.

An adjustable frame device for a profiled sail device includes a fixed luff-sided first frame portion and a leech-sided second frame portion. The second frame portion includes a first flexible sail batten and a second flexible sail batten that are movable with respect to one another in a sail-batten longitudinal direction to adjust the frame device, with one of the sail battens serving as a compression batten and the other of the sail battens serving as a tension batten. An adjustable profiled sail device includes a first profiled surface against which air can flow, a second profiled surface against which air can flow, with the first profiled surface and the second profiled surface being spaced apart from one another, and an adjustable skeleton device disposed between the profiled surfaces. The skeleton device includes at least one adjustable frame device.

In one embodiment of the invention, a folding stowable seat for use on a boat is provided that includes a compartment in which the seat is stowed when not in use; a moveable lid attached with a hinged connection to the boat, the lid covering the compartment when the seat is stowed, and a top side of the lid configured for use as a step on the boat for use by boaters, and the lid is raisable about the hinged connection to an upright position to move the seat into a use position; a seat back; a seat bottom; and a movement assembly connecting the seat bottom to the compartment, the movement assembly facilitating movement of the seat bottom from a stowed position contained entirely within the compartment to a use position wherein the seat is at least partially outside of the compartment.

An apparatus and methods according to the present invention provides a human powered catamaran-styled watercraft and methods of configuring and operating the watercraft. The watercraft generally comprises at least one hull in communication with a folding collapsible frame, wherein in the frame comprises a center rack pivotally joining hulls of hull sets to provide for common pivoting of the hulls during articulation of the watercraft, thereby the hulls and frame are in further communication through a at least one pivot pad which provides for slidable pivoting of the hulls during articulation of the watercraft. A method of folding and reversibly extending the watercraft to provide for optimized storage is provided. A method of operation of the watercraft to provide for articulation of the watercraft is provided.

A rod for repelling sharks is disclosed. Magnets are connected to the rod along its length. If necessary, the rod may be extended. Additionally, one or more flotation devices may be connected to the rod to manipulate or adjust the buoyancy of the system, depending on the user's objective(s). The rod is connected to a fishing line once a fish is hooked and is in close proximity to the boat or other structure from which the fisherman is fishing. The weight of the rod and magnets cause the rod to slide down to the end of the fishing line, where the rod will come in contact with the hooked mouth of the fish. As the fish struggles during the fight, the rod creates a protective magnetic field around the fish to deter sharks from engaging the fish.

Networkable digital life jackets and associated methods are disclosed. An example life jacket includes a state manager and a swarm manager. The state manager is configured to selectively operate the life jacket in one of multiple operational states of the life jacket based on data obtained from one or more sensors of the life jacket. The swarm manager is configured to form a swarm network including the life jacket and one or more other life jackets.

Wakeboat hull control systems and methods are provided to monitor the orientation of the wakeboat hull in the surrounding water, and to automatically control wakeboat ballast components to achieve or maintain desired hull orientations. Systems and methods are provided to measure, store, and recall hull orientation. Systems and methods are also provided to enable automated action to improve the safety, automation, performance, convenience, and marketing advantage of wakeboat ballast systems.
