Watermaker

A watermaker is a marine desalination system that converts seawater into fresh drinking water using reverse osmosis. Charter guests encounter this device on longer voyages or when cruising in remote areas without access to shore water supplies. Operating a watermaker requires engine or generator power and produces limited quantities of fresh water daily, typically 10-50 gallons per hour depending on system size. Understanding water production capacity is important for multi-day cruises, as fresh water consumption for drinking, cooking, and washing is an essential boat resource.
