A pontoon boat is provided that includes at least two pontoons running longitudinally beneath the boat and providing buoyancy thereto; a deck framework mounted above and connected to the pontoons; a deck mounted on the deck framework; a recessed deck portion extending downwardly through the deck and the deck framework, the recessed deck portion forming a cavity into the deck including a bottom and side walls forming a basin extending into and beneath the deck; and at least one seat adjacent the recessed deck portion and mounted to the deck.

Embodiments include a retrofit pontoon system including a pontoon, the pontoon having a pontoon body defining a first cavity, a retrofit assembly, the retrofit assembly including a first lateral tube, wherein the first lateral tube is sized to pass through a first aperture formed in the pontoon body and a selectively fillable container, where the first lateral tube is operably coupled with the selectively fillable container, a main tube, where the main tube is fluidly coupled with the first lateral tube, and a pump, the pump being coupled with the main tube such that operation of the pump selectively fills and drains water from the selectively fillable container, where filling the selectively fillable container lowers the profile of the pontoon in the water and emptying the selectively fillable container raises the profile of the pontoon in the water.

The oxygen tank flotation device is a floating structure adapted for use in recreational water activities. The oxygen tank flotation device is adapted for use with respiratory equipment that is required for use during recreational water activities. The oxygen tank flotation device receives and stores respiratory equipment, such as an oxygen tank, in such a manner that the respiratory equipment will float when the oxygen tank flotation device is placed in a body of water. This arrangement allows the respiratory equipment to float near the user when the user is involved in recreational water activities. The oxygen tank flotation device comprises a vessel, a first float, and a second float.

A hydrofoil system provides lift to a motor-powered displacement hull without raising the hull out of the water. The hydrofoil system includes a pair of laterally opposed forward hydrofoil wings positioned respectively on the first pontoon and second pontoon forward a center of gravity of the hull. The forward hydrofoil wings extend laterally inboard and downwards towards each other. The hydrofoil system also includes a pair of laterally opposed aft hydrofoil wings positioned near the stern of the hull on the first pontoon and second pontoon respectively. The aft hydrofoil wings extend laterally inboard towards each other and have an upper surface with convex curvature that extends from the respective first pontoon or second pontoon to an inboard terminal end thereof.

An expansion deck system for vessels includes a frame assembly for positioning between a stationary floor of a vessel and a plurality of pontoons of the vessel. The frame assembly including a first side with a first elongated opening, and a second side with a second elongated opening. One or more sliding deck members are telescopically connected to the frame assembly by one or more sliding rails and transition between a retracted position and an extended position. In the retracted position the one or more sliding deck members are positioned between the floor and pontoons of the vessel, and in the extended position the one or more sliding deck members are positioned alongside the frame assembly.

A floating apparatus for supporting a grill including a substantially rectangular float having an outer rim, a substantially rectangular base disposed within the outer rim, and a cavity disposed within the outer rim above the base. Each of a right grill support and a left grill support of a pair of grill supports has a linear base rod and an upper support attached to a top surface of the base rod. The base rod of each of the right grill support and the left grill support is disposed within the cavity. A plurality of magnets is disposed within a middle segment of the upper support of each of the right grill support and the left grill support. At least one cup holder unit is disposed within the cavity of the float. A portable outdoor grill is removably securable to the plurality of magnets.

A pontoon boat including a thruster system is disclosed.

A pontoon boat is provided that includes a deck and a plurality of pontoons running longitudinally beneath the deck and providing buoyancy to the pontoon boat. The plurality of pontoons include a multi-chine configuration that increases the stability of the pontoon boat and provides handling characteristics similar to that of a hulled boat. The plurality of pontoons may include two outer pontoons and a third pontoon positioned laterally intermediate the outer pontoons. The third pontoon may include a plurality of chines, and each of the outer pontoons may include at least one chine. At least a portion of each of the at least one chines of the outer pontoons may be positioned vertically below the plurality of chines of the third pontoon. The chines on the third pontoon may extend longitudinally further than each of the at least one chines of the outer pontoons.

A docking system for a boat includes spring-loaded bumpers that protrude from the bow of the boat, thereby enabling a boat operator to dock the boat against a vertical structure such as a seawall. Anchors are mounted with respect to the seawall to which ropes may be tied to secure the boat and maintain contact between the bumpers and the seawall. Anchors may be supported above the water level by floats, which automatically adjust the height of the anchors in response to changes in the water level.

A pontoon boat is provided that includes a deck and a plurality of pontoons running longitudinally beneath the deck and providing buoyancy to the pontoon boat. The plurality of pontoons include a multi-chine configuration that increases the stability of the pontoon boat and provides handling characteristics similar to that of a hulled boat. The plurality of pontoons may include two outer pontoons and a third pontoon positioned laterally intermediate the outer pontoons. The third pontoon may include a plurality of chines, and each of the outer pontoons may include at least one chine. At least a portion of each of the at least one chines of the outer pontoons may be positioned vertically below the plurality of chines of the third pontoon. The chines on the third pontoon may extend longitudinally further than each of the at least one chines of the outer pontoons.
