An air-cooling device for a boat includes a plurality of misting modules and a pump. Each misting module comprises a housing that defines an interior space. The housing has a back that is coupled to a sidewall of a boat. A plurality of slots is positioned in the housing and is configured for air to enter the interior space. A plurality of orifices is positioned in a front of the housing. A plurality of fans is coupled to the housing and positioned in the interior space. Each fan is positioned in an associated orifice. A plurality of nozzles is coupled to the front of the housing. The pump is operationally coupled to the nozzles and a source of water. The pump is positioned to pump water through the nozzles to form a mist. The fans are configured to disperse the mist to cool an area proximate to the housing.

A dehumidification system for a marine vessel includes a dehumidifier having a supply and return. The dehumidifier is supported in an interior space of the marine vessel, separated from the outside ambient environment. The supply provides dehumidifier to air through dedicated ducting to one or more locations throughout the vessel. The return includes dedicated ducting that draws air from a return grate located away from any doors on the vessel that are open directly to the outside ambient air. For example, the return grill is positioned in a space below deck. The dehumidification system includes a controller that is positioned near the return grate.

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.
