Hydrogenerators

Marine Hydrogenerators & Renewable Energy Generation Systems for Offshore Sailing Yachts

Technical Marine Supplies supplies a specialist range of marine hydrogenerators and renewable onboard power generation systems designed for cruising yachts, offshore racing yachts and long-distance sailing vessels. Featuring industry-leading Watt & Sea hydrogenerators, these systems enable sailors to generate clean, reliable electrical power while underway, reducing dependence on engine charging and supporting energy self-sufficiency during extended voyages.

Hydrogenerators have become an increasingly popular solution for offshore sailors seeking efficient renewable energy generation. By harnessing the movement of water past the vessel, hydrogenerators convert hydrodynamic energy into electrical power, helping to supply onboard systems including navigation electronics, communications equipment, autopilots, lighting and battery charging systems.

Technical Marine Supplies offers the complete Watt & Sea range, including the Cruising 300, Cruising 600, Racing 600 and POD 600 Hydrogenerator systems, together with a comprehensive range of hydrogenerator accessories and replacement parts. Designed for exceptional efficiency, reliability and ease of use, Watt & Sea products are trusted by offshore cruisers, short-handed sailors, ocean racers and professional sailing programmes worldwide.

The latest generation of Watt & Sea hydrogenerators incorporates advanced brushless technology, improved hydrodynamic design and enhanced corrosion resistance. Available in multiple output capacities and installation configurations, these systems can be tailored to suit a wide variety of vessel sizes and onboard energy demands. For yachts where transom mounting is not practical, the innovative POD 600 offers a discreet under-hull installation with minimal visual impact and excellent electrical performance.

By reducing engine running hours and fuel consumption, hydrogenerators provide a sustainable and environmentally responsible method of generating onboard power. They are particularly well suited to offshore passagemaking, short-handed sailing and renewable energy-focused vessel projects where reliability and energy independence are critical.

As a specialist B2B marine distributor, Technical Marine Supplies supports boat builders, yacht service companies, marine electricians, offshore racing teams and OEM manufacturers throughout the UK and Europe. Our experienced technical team can assist with system specification, integration and renewable energy planning for both new-build and retrofit projects.
