Disclosed herein is an inflatable watercraft barrier in one example having an inflatable perimeter tube. Also disclosed is a diaphragm sealed to the perimeter tube to form the watercraft barrier between a watercraft and the water in which the watercraft barrier and watercraft float. In one example, a portion of the perimeter tube forms a gate portion which is at least partially selectively deflated so as to be denser than water, and therefore rotates about a gate pivot such that the watercraft may enter the watercraft barrier through the gate portion. Also disclosed is a water pump in fluid communication with the watercraft barrier so as to evacuate water from between the watercraft barrier and the watercraft.

An inflatable water-based motorised device docking station is described. The inflatable water-based motorised device docking station includes an inflatable tube configurable to form an open ended area to receive a water-based motorised device; a floor area coupled to a portion of the inflatable tube; and a ballast bag with dump attached to the floor area and configured to stabilise the inflatable water-based motorised device docking station.

A boat lift is attached to piles driven into the earth or to another object. The boat lift is held in horizontal position relative to piles or the object to which it is attached, but vertical movement of the boat lift relative to the object is permitted. The boat lift is connected to the piles by modular units or cube constructs that have a post extending there through. The post has a blade extending from it. The blades are attached at an angle, according to the application, to pile guides that engage piles. The pile guides vertically traverse the piles, permitting the boat lift to move vertically relative to the object, but fixing the horizontal position of the boat lift.

A watercraft float having a deck surface and bottom surface, a watercraft receiving area, a first post having a base, side, and top surface, wherein the first post is positioned on a first side of the watercraft receiving area, a second post having a base, side, and top surface, wherein the second post is positioned on a second side of the watercraft receiving area, and a railing, wherein the railing releaseably engages the two posts, wherein the base of the first post and the base of the second past are engaged to the deck surface, wherein each post is configured so that a user can propel a watercraft onto the float utilizing the post, and wherein the watercraft receiving area is configured to receive a watercraft.

A boat support elevator is presented. The boat support elevator comprises a frame and a plurality of ballasts secured to the frame; each ballast being connected with a tube for managing air volume in each ballast. Also presented a ballast system comprising an air pump, and a plurality of ballasts each secured fluidly connected to the pump through a pressuring port, and comprising a drain port for water to enter and exit the ballasts. According to one aspect, some ballasts are connected to the air pump through a connection to another ballast. Also presented a ballast comprising a top protrusion and a bottom protrusion for minimizing undesired restrained air and water.

One example provides a floating drive-on pontoon port including a plurality of floating sections pivotally coupled together in series with one another to form an articulating port track base and an articulating starboard track base extending longitudinally in parallel with one another, the port and starboard track bases each having a lower surface to be disposed in water and an opposing upper surface to face away from the water. A port transport track extends longitudinally across the upper surface of the port track base, and a starboard transport track extends longitudinally across the upper surface of the starboard track base and in parallel with the port transport track, the port and starboard transport tracks each comprising a series of spaced apart rollers configured to respectively receive, transport, and support a port pontoon and a starboard pontoon of a pontoon during loading, unloading, and storage of the pontoon boat on the pontoon port. A lateral position of the port and starboard transport tracks relative to one another is adjustable to adjust a lateral distance between the port and starboard transport tracks to accommodate pontoon boats of different widths.

A system, adapted to determine that automatic docking of a boat is completed. The system including a control unit including a processor configured to switch a control mode of the control unit to an automatic docking mode; output a control signal for controlling an automatic steering of the boat when the control mode is switched to the automatic docking mode; obtain a vibration that is exerted on the boat, wherein, when the control unit is in the automatic docking mode, the control unit is configured to end the automatic docking mode when the control unit detects the vibration.
