A Method and Apparatus for Wake Enlargement System have been disclosed. By using water pick ups that are mounted or deployable on a boat controlled filling of ballast tanks is possible without the use of pumps.

A system for monitoring a physical change of a marine structure includes a complex optical measuring instrument configured to detect a behavior and structural change of the marine structure by using at least one optical sensor by means of optical fiber Bragg grating.

The present disclosure relates to pontoon shields. The pontoon shields disclosed herein may, for example, protect pontoons from damage and/or enhance the aesthetic appearance of pontoons. The shields may be fashioned from one or more segments of resilient material configured to attach along a longitudinal aspect of a pontoon. The shields may be fashioned from a single segment, or from one or more segments configured to mate with one another. The shields may be attached to a pontoon, for example, via an adhesive, weld, and/or one or more brackets, or other mechanical means.

A system and process is provided to deplete or remove moisture from wood coring in boats by piercing 20 a fiberglass outer skin; forming 30 bores or holes 200 in wood coring to form an exposed portion; processing ambient air 35 to create processed air; pumping or displacing 40 processed air into the bores or holes 200; penetrating 50 an exposed portion 80; with a sealant 100; and filling 60 the exposed portion 80 with a sealant 100.

A robot for cleaning submersed marine structures is provided. The robot has a drive system for traversing the robot over the submersed structure. The robot further has an attachment system for attaching the robot to the submersed structure. The robot further has a cleaning arrangement for removing biofouling from the submersed structure as the robot is traversed thereover. The robot further has one or more flexible detector strips which contact the submersed structure as the robot is traversed thereover. The strips have a plurality of electrodes and are formed from electroactive polymer material which produces electrical signals in the electrodes on deflection of the strips. The signals are indicative of the surface roughness of the submersed structure.

A cleat having an adjustable anchoring system configured to suspend a bumper. The cleat has a first horn located opposite a second horn. A support structure is connected to the cleat. A recess of the support structure has a ridge protruding from a wall surface of the recess. The ridge is configured to deform a portion of rope. A bore of the support structure is configured to receive a fastener. A base has a bore configured to receive the fastener. The bore of the support structure is oriented to align with the bore of the base. The base has two ramps that protrude from a wall surface of a recess of the base. The two ramps form a pocket that can have a protrusion configured to bind a portion of the rope when the fastener is tightened.

A resin infusion repair device and method for repairing a wooden boat deck having a repair area that includes voids between the planking of the boat deck and the as built surface under the boat deck planking. A vacuum cover provides an airtight cover of the repair area. A vacuum suction line is inserted into the vacuum cover. A vacuum pump is connected to the vacuum suction line and provides vacuum suction at the repair area. A resin supply line is inserted through the vacuum cover. A resin supply source is connected to the resin supply line. The vacuum pump provides a vacuum suction that draws resin from resin supply source through the resin supply line and into the repair area so that the voids are all filled with the resin. In a preferred embodiment, the wooden boat deck is a teak boat deck.

A marking machine for sections of vessels, including: a marking device and a gantry. The gantry includes rail wheels, horizontal beams, and upright columns. The horizontal beams include an upper beam, middle beams, and lower beams. The marking device is disposed on the upper beam of the gantry. The marking device includes a trolley and a marking arm. The trolley hangs on the upper beam. The marking arm includes a plumbing arm, a swing arm, a first universal joint, a second universal joint, a first Z-shaped steering knuckle, a second Z-shaped steering knuckle, a telescopic arm, and a penholder. The plumbing arm is fixedly connected to the lower part of the trolley. The first universal joint is disposed on the plumbing arm. The first Z-shaped steering knuckle is connected to the first universal joint.

A buoy includes a turret coupled to a buoyant body using a bearing assembly; a deckhouse disposed on the buoyant body; and a bearing retainer configured to retain the bearing assembly and to releasably attach to the turret. The buoy may also include a locking mechanism having an inner opening in the turret, an outer opening in the buoyant body, and a locking member configured for insertion through the inner and outer openings. In one embodiment, the inner opening is out of alignment with the outer opening during operation of the buoy. The buoy may further include a detachable cover on the deckhouse, wherein the cover is configured to attach to the bearing retainer.

A submersible vessel comprising: an elongated hull; at least one propeller mounted on a forward end of said hull and adapted to move said hull through water; said at least one propeller being of a size and configuration such that when it is rotated at an appropriate speed, it generates supercavitated water flowing from said at least one propeller and thence along an outer surface of said hull so as to diminish friction on the outer surface of said hull and facilitate high underwater speeds.
