Desalination for sailboats employs RO technology, where seawater is forced through a reverse osmosis membrane. This membrane allows water molecules to pass through while blocking salt and impurities, producing fresh drinking water on one side and concentrated brine on the other.

Energy Source and Efficiency

Watermakers on sailboats are powered by various sources like the boat’s engine, generators, solar panels, or wind turbines. The choice of power source impacts the system’s efficiency and environmental impact. Sailors often prioritize sustainable options, such as solar panels or wind turbines, to reduce reliance on fuel-based systems and minimize their carbon footprint.

Different product water quality requirements have different requirements for the capacity of the watermaker for sailboat. For example, if you only need to use it for some non-drinking ways, the requirements for it may not be very high. But if it is necessary to obtain fresh water, the quality of the produced water must reach food grade.

How big is your boat? Water makers for boats are usually designed to be compact and portable, so they don’t take up much space, but you still need to consider the space to install them. Seawater desalination equipment with different capacities usually has different fuselage sizes and weights. A small watermaker for sailboat is enough for small boats and personal use.

Capacity is almost the key factor that determines the price of a marine water generator. Equipment with different capacities Generally, the size of the equipment is different, and the design process may also be different. You can make the best choice based on your daily water needs on board.

Energy Supply

Improper handling may completely damage the generator. A water maker with low maintenance must be the ideal choice.
