Demystifying the Operations of Marine Watermakers

Marine watermakers, an indispensable component on sailboats and other sea-bound vessels, serve the critical function of transforming saline ocean water into potable fresh water. But what mechanisms make this transformation possible?

Underlying this ingenious device is the science of reverse osmosis. Central to each marine watermaker is a semi-permeable membrane. This fine film allows the passage of water molecules while hindering larger structures, such as salt.

In operation, seawater is subjected to intense pressure, propelling it through the membrane. This phenomenon, known as reverse osmosis, effectively separates the water molecules from the saline content. The resultant fresh water is accrued and conserved in tanks, ready for consumption and other uses.

Marine watermakers derive their operational energy from varying sources, governed primarily by the unit’s size. Electricity is a common power source, particularly for the larger, more permanent installations. For the smaller, portable models, energy can be harnessed from something as accessible as a car battery.

For those with diesel engines on board, some watermakers are specially designed to run off it, allowing for further equipment integration and efficiency.

It’s worth noting that while reverse osmosis is a relatively energy-intensive process, continued advancements in marine watermaker technology are progressively reducing the power demand, enhancing both the efficiency and environmental impact.

Navigating the Options: Choosing the Ideal Marine Watermaker

Breaking Down the Components of a Sailboat Watermaker

Determining the most suitable watermaker for a sailboat starts with understanding the integral components of this vital device. At its core, a watermaker consists of a filtration system, a pump, a pressure vessel, and a control panel.

The filtration system purifies the intake salt water, removing substantial contaminants before it proceeds to the heart of the operation — the pressure vessel housing the reverse osmosis membrane. This area is where the magic happens, with the high-pressure pump pushing the water through the membrane, effectively separating the salt from the water molecules.

The control panel serves as your interaction point with the watermaker, allowing you to activate the unit and monitor its operation. The advanced models are equipped with digital panels offering real-time insights into the unit’s functioning and alerting you of any issues requiring attention.

Deciphering the Ideal Size for Your Marine Watermaker

Assessing what size of watermaker is befitting to your needs relies heavily on your sailing nature. Are you an occasional sailor indulging in brief jaunts on the local water bodies? A modest, compact unit should serve your freshwater needs adequately, with opportunities to top up your tanks from dockside resources. If, however, you belong to the breed of adventurous sailors drawn to the far reaches of the open ocean, you’d fair better with a larger, robust model capable of delivering higher water output.

A significant factor to consider is the potential headcount aboard. Whether you sail solo, as a couple, or with a group, water consumption needs escalate with every added individual.

Another indispensable factor is your water consumption habits. Do you cherish lengthy, refreshing showers? Do you prefer flushing your boat with freshwater regularly? Do your toilets operate on freshwater flushing systems? Each of these elements pushes your water demand higher, necessitating a more substantial watermaker.

Crunching the Numbers: Marine Watermaker Costs

The market teems with marine watermakers from the economical to the extravagant. Do-It-Yourself enthusiasts swear by self-made watermakers, only incurring the costs of sourcing the components. However, for those less technically inclined, a quality watermaker for a standard cruising sailboat (approximately 40ft) tends to hover in the range of £3000-£5000.

Larger vessels signify larger water demands and, subsequently, costlier watermakers, sometimes until £10,000. Bargain hunters can fulfill their needs without breaking the bank, with second-hand units or smaller, more affordable models available.

Decoding Watermaker Power Consumption

The efficiency of watermakers differs across brands. However, a general estimate suggests that it takes approximately 10 Watt-hours to generate a litre of water (equating to roughly 0.8 Amp-hours from a 12-volt battery).

Deciding on Space Allocation for Your Marine Watermaker

Marine watermakers, despite their invaluable utility, require a fair bit of space, averaging around the size of a small freezer. This can pose a challenge on vessels where space is limited. Thankfully, manufacturers are addressing this constraint by introducing compact units that occupy minimal space, roughly the dimensions of an ordinary coffee maker. These compact models are ideal for smaller boats where space economy is paramount.
