Watt&Sea racing hydrogenerators have radically modify the energy management on board and have become essential pieces of equipment in mythical offshore races like the Vendée Globe or the Route du Rhum. The VOLVO OCEAN RACE has chosen to place its confidence in Watt&Sea, by equipping the Volvo Ocean 65 fleet present on the start line on the 22nd October 2017 !
Racing hydrogenerators are equipped with a controlled pitch propeller, functionning electronically with an independent system. The drag is minimal and the energy output is optimal on a speed range from 5 to 30 knots.
MPPT (Maxi Power Point Tracking) and Step-Up technology
RS485 output for hydraulic pump and pitch regulation
Racing hydrogenerators are equipped with a controlled pitch propeller, such as an "aeroplane propeller".
High speed launch is possible, putting the blades in the feathered position.
Watt&Sea racing hydrogenerators tend to be fixed directly on the boats transom, thanks to the fixation kit included in the pack.
The lifting and immersion is done like with a dinghy rudder.
The effective charge power permits to lift the hydrogenerator up when the batteries are full.
Operations are facilitated by premium quality equipment purchased : a low friction ring multiply the effort, and Harken clam-cleat maintains the hydro in the good position.
