A system for use with a Luxury Boat, when the Luxury Boat is in Temporary Dry Storage involves a sensor is configured to sense a trigger signal from a boat-based pump controller indicating that raw water is to be pumped to at least one Auxiliary System and send a signal to a second controller that will cause the second controller to start a pump, external to the Luxury Boat, pumping antifreeze from a reservoir to at least one Auxiliary System on the Luxury Boat in Temporary Dry Storage. An associated method is also disclosed. A system involving a a raw water collar that forms a seal against a hull of a Luxury Boat about a scoop strainer of the Luxury Boat through which raw water can be supplied when the Luxury Boat is in Temporary Dry Storage is also described.

A cooling apparatus for cooling a fluid by surface water includes at least on tube for containing and transporting the fluid in its interior, the exterior of the tube being in operation at least partially submerged in the surface water so as to cool the tube to thereby also cool the fluid. The cooling apparatus also includes at least one light source for producing light that hinders fouling on at least part of the submerged exterior.

A guide plate having depressed portions is provided between an array of heat exchanger tubes, herein after tubes, arranged horizontally side-by-side and a next lower array of tubes arranged horizontally side-by-side, and is positioned with the lowest parts of the depressed portions near crest portions of respective lower tubes. The guide plate conveys a liquid D on outer surfaces of respective upper tubes onto similarly positioned lower tubes even when the tubes move in a right-and-left direction. A falling film heat exchanger installed in a ship, an offshore structure or the like can avoid reduction in heat exchange performance, even when the ship or the like inclines and swings, by substantially evenly distributing and dropping a liquid onto the crests of the tubes and causing the liquid dropped from the tubes located in an upper array to fall onto the tubes located in the next lower array.

Disclosed is a water intake system for a floating vessel in a body of water, which includes within the hull of the vessel an intake compartment for taking in water from the body of water and a distribution compartment for distributing and supplying the water to one or more consumer units within the floating vessel. The intake compartment is arranged below a lowest operational draught of the vessel and has an inlet in a bottom region of the intake compartment. The intake compartment is coupled by a conduit to the distribution compartment for allowing water to flow into the distribution compartment. The water intake system further includes a water lift hose that is connected to the inlet and is extendible below the hull of the vessel.

A boat hull cooling and marine-drive system intended for use in a primary shallow water bottom environment includes a boat hull with an integrated internal engine heat exchanger, marine drive system and steering assembly. The steering assembly incorporates a ring-within-a-ring steering mechanism and an obstacle resistant shoe plate. Stabilizer fins positioned above the shoe plate at a position forward of the spinning propeller allow air and water to exit from the rear of the stabilizer fins away from the spinning propeller

A remote monitoring method, performed at a central location by a controller associated with the central location, for use with multiple remotely located boats is described involving determining, based upon first location information, second location information and tide information, whether a water-fed air conditioner of a first boat or a water-fed air conditioner of a second boat should be shut off or turned back on due to tide-caused depth changes at a first location or second location. A controller for a boat has at least one processor; and programming which, when executed will cause the at least one processor to, when the boat's air conditioner is operating, cause at least a water pump pumping water to the condenser to shut off at a time, based upon a depth at the current location of the boat of less than a specified minimum acceptable depth.
