Wind Power / Towed Turbines

WIND POWER

Maintaining your batteries in an acceptable state of charge when mains power is not available or on a swinging mooring, then an alternative power source is freely available - WIND.

Wind chargers enable your batteries to be \\\'topped up\\\'.
This is particularly important when the boat is left unattended for long periods.

When long distance sailing, a wind charger can provide a significant amount of power.  Thus engine alternator charging is reduced and fuel usage is minimised.

The size of a wind charger required, is largely determined by the size of boat and the electrical power required.

If, for example, you are a weekend sailor and need to top up an engine battery, then a low output wind charger will suffice.
However, if you have long passages, then a higher output wind charger will be required.

TOWED TURBINES

Typically, sailing at 5/6 knots, a water turbine will generate 5 amps continuous current, 120 amps per day, which would maintain state of charge and probably meet the daily loads required.

A water turbine is mopre likely to be suited for long distance sailing.
