A vent for use with a film-wrapped watercraft includes a body having a piercing tip at a first end and a hood member at a second end. A guide member extends from the body to an area proximate the piercing tip. The guide member includes a positioning structure proximate the piercing tip. A vent member is positioned under the body. Apertures of the vent member are positioned between a lower edge of the vent member and the hood member. The positioning structure is configured to slidably engage a watercraft wrap and allow the piercing tip to pierce the watercraft wrap. The positioning structure and the piercing tip are configured to guide a portion of the watercraft wrap over the body and under the guide member and the positioning structure.

A do-it-yourself-friendly self-contained marine air conditioning unit, marine air conditioning system, and method for installation is disclosed. The unit includes a seawater cooling circuit, a refrigerant circuit, and a blower assembly. The refrigerant circuit includes a reverse valve connecting a compressor, an evaporator, and a refrigerant tube thermally engaged with a titanium condenser coil. The seawater cooling circuit includes the titanium condenser coil. The titanium condenser coil has a titanium condenser coil outflow and a titanium condenser coil inflow. The blower assembly is mounted in communication with the evaporator, wherein the blower assembly may pull air through the evaporator. This blower is capable of achieving up to 270-degrees of rotation about a single axis. The system also includes a universal controller to allow for optimal integration with existing systems.

A system for providing raw water for cooling of one or more Auxiliary Systems of a Luxury Boat, when the Luxury Boat is in Temporary Dry Storage involves a pump, external to the Luxury Boat, a controller coupled to the external pump and a sensor coupled to a boat-based pump controller on the Luxury Boat. The sensor is configured to sense a trigger signal from the boat-based pump controller indicating that raw water is to be pumped to the one or more Auxiliary Systems and send a signal to the controller that will cause the controller to start the external pump pumping raw water to the Luxury Boat. A related method for controlling raw water supply to one or more Auxiliary Systems of a Luxury Boat, when the Luxury Boat is in Temporary Dry Storage is also described.
