Boating is an exhilarating experience, but access to fresh water can be a significant challenge when you're miles away from the shore. Enter the boat watermaker – a device that can transform seawater into potable water, ensuring a continuous supply of fresh water for drinking, cooking, and cleaning. In this comprehensive guide, we'll explore everything you need to know about boat watermakers, from their functionality to the best models on the market.
What is a Boat Watermaker?
A boat watermaker, also known as a marine watermaker or desalination system, is a device designed to convert seawater into fresh water by removing salts and other impurities. There are primarily two types of watermakers used on boats: Reverse Osmosis (RO) Watermakers and Distillation Watermakers.
How Does a Boat Watermaker Work?
Most boat watermakers use reverse osmosis (RO), where seawater is forced through a semi-permeable membrane that filters out salt and other impurities. A typical RO watermaker includes: Pre-filters, High-pressure Pump, RO Membrane, Post-filters, and Control Panel.
Benefits of Using a Watermaker on Boats
Having a watermaker onboard means you no longer need to rely on marina facilities for fresh water. By generating your own fresh water, you reduce the need for plastic bottled water, thereby minimising plastic waste and your environmental footprint. While the initial investment in a watermaker can be significant, it pays off in the long run by reducing the need to purchase and transport fresh water.

Choosing the Right Watermaker for Your Boat
When selecting a watermaker, consider factors such as boat size, crew, cruising area, and power availability. Calculate your daily water needs and choose a watermaker that can comfortably meet those requirements. Budget considerations are also important, as watermakers range from a few thousand to tens of thousands of pounds.
Installation and Maintenance of Boat Watermakers
While some watermakers can be installed by skilled DIYers, professional installation is recommended to ensure optimal performance and longevity. Regular maintenance includes changing filters, checking for leaks, and sanitising the system to prevent microbial growth. Common issues include low water production, high salinity levels, and strange noises, which could indicate pump issues or air leaks in the system.
Watermakers for Yachts
Yachts typically require higher capacity watermakers due to their size and the number of people onboard. High-capacity watermakers can produce hundreds of gallons per day and often include advanced features like automated operation and remote monitoring.
Portable Watermakers: Pros and Cons
Portable watermakers are compact, lightweight, and can be used in emergencies or on smaller boats where a permanent installation isn't feasible. However, they typically have lower water production rates and may require manual operation, making them less convenient for regular use.
Conclusion
Boat watermakers are invaluable tools for any serious boater or sailor, offering convenience, independence, and a sustainable way to ensure a fresh water supply. By understanding the different types, choosing the right model, and maintaining it properly, you can enjoy all the benefits these systems offer. Whether you're cruising coastal waters or embarking on a long offshore journey, a watermaker can make your boating experience more enjoyable and environmentally friendly.
