Sailing enthusiasts, imagine powering your vessel with the very essence of your environment – the sea itself. Water generators, like the groundbreaking Watt&Sea system, do just that. In this post, we delve deep into the world of water generators, uncovering their efficiency, minimal maintenance requirements, and unobtrusive operation. Let’s set sail into a greener future!

Efficiency on the Move

One of the most remarkable features of water generators is their ability to generate electricity as your vessel sails. These innovative systems harness the energy produced by the movement of water against their adjustable blades. This unique characteristic makes them highly efficient, especially during passages and while cruising. As you navigate the waves, Watt&Sea quietly transforms water’s kinetic energy into a renewable power source.

Quiet and Unobtrusive

Much like wind generators, water generators operate with a hushed grace that doesn’t disturb the tranquility of your sailing experience. Imagine gliding across the water, listening to the soothing sounds of the sea, without the disruptive hum of traditional generators. Watt&Sea’s commitment to preserving the serenity of your voyage is truly remarkable.

Minimal Maintenance

For sailors, the journey is everything. Water generators enhance this experience by requiring minimal maintenance. This means you can focus on your adventure, not on energy management. However, it’s important to look after your propellers and carry spare units, especially if you plan on crossing seaweed-heavy waters, as we did during our Atlantic journey towards the Caribbean.

Watt&Sea stands out as a trusted hydrogen supplier, offering both 300 Watt and 600 Watt systems with varying shaft lengths. These systems are designed to be fixed at the transom of your boat, weighing between 8 to 9 kilograms depending on the shaft length. They are compatible with 12 and 24 Volt systems. Remember to disconnect the hydrogenerator when your lithium-ion batteries are full, for safety reasons. You have the option to lift the system out of the water or install a relay to disconnect the power from the batteries. The 600 Watt system is priced at €4500, plus the cost of a converter.

The Power of Minimal Drag

Concerned about drag? Don’t be. The hydrogenerator’s drag is negligible, especially when compared to the overall weight and drag of your yacht. Meaningful power generation kicks in at speeds as low as 4 knots. For a graphical representation of this, refer to the chart below.
