RACING HYDROGENERATORS

Product catalog summary

Overview: The document provides detailed information on Watt&Sea's Racing Hydrogenerators and Windgenerators, highlighting their specifications, performance, and advantages for offshore racing.

Racing Hydrogenerators:

Equipped with a controlled pitch propeller, these hydrogenerators optimize energy output with minimal drag across speeds from 5 to 30 knots.
Available in two versions: Aluminium Racing and Carbon Racing.
Key specifications include a charging voltage of 12 or 24 V, maximum speed of 30 knots, and a leg length of 610 mm.
The hydrogenerators are lightweight, with the aluminium version weighing 8.2 kg and the carbon version 7.7 kg.
They come with a 2-year warranty and are compatible with all battery types, including Lithium.

Racing Windgenerators:

Developed in collaboration with the MACIF Design Team, these windgenerators aim for full autonomy on racing trimarans.
Features include high stability due to a downwind design, high performance, waterproof construction, and a wide wind range with a 'storm mode' for winds up to 50 knots.
The design ensures low drag and safety, with blades positioned to the back for easy handling.
Capable of producing 120W (10A in 12Vcc) at 20 knots.

Conclusion: Watt&Sea's innovations in hydrogenerators and windgenerators offer significant advantages for racing applications, including efficiency, stability, and durability, making them essential equipment for offshore races.

©Jean-Marie LIOT / ALEA / MACIF This new-design wind-generator is under testing since one year in collaboration with MACIF Design Team with the goal to achieve full autonomy on their giant trimaran. We applied our knowledge from well-proven hydrogenerator technology to transpose its efficiency to wind generation. The result is a powerful and lightweight windgenerator. The prototype installed on MACIF trimaran showed great durability during François Gabart’s solo-round-theworld record. Compared to conventionnal wind-generators this new design offers unique advantages for «racing» use : High stability...
