Hydrogenerators Cruising

A good management of the energy on board is the key point to sail in total serenity, regardless the consumption of the on-board electronics or other electrical appliances. Watt&Sea’s hydrogenerators propose an energy self-sufficiency solution on board of cruise or race boats, in the respect of the environment.

Stemmed from ocean racing research, the first Watt&Sea hydrogenerator gets started in 2008 with the objective of an optimal output associated to a negligible drag, letting the boat sail with a positive energy while loading the batteries. Our hydrogenerator has since then being improved taking into account users’ comments, so that we are proposing today an even more reliable and efficient product.

Validated on all seas around the globe, they are the most powerful, reliable and lightest available on the market.

Fastening on the transom…

Watt&Sea’s hydrogenerators are usually fastened on the transom of the boats thanks to the fastening kit supplied (adapted to straight and vertical transom). The lifting up and down are similar to a rudder blade’s handling. The charge power being so important, it allows to lift the hydrogenerator up when batteries are fully loaded.
Handling makes it easier thanks to high quality steering : an Antal low friction ring to divide the effort plus a Harken cam cleat to maintain the unit in its position.


… or straight under the hull !

New model POD 600 to be fastened straight under the hull !

Tested since 2014 by a few privileged sailors, this version has been able to demonstrate those useful advantages :

  • invisible
  • no complicated handling up and down
  • easy start-up
  • electrical output is the same compared to classic models

Racing Hydrogenerator

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.

Variable pitch propeller

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.


Fastening on the stern…

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.
