| A word about wind turbines..We cruised on a 30 foot sailboat since 2005 with a 400 watt wind turbine..until 2008 it was our only charging other than the diesel..At anchor it was pretty good at supplying our power needs as long as we were in places like the Bahamas ,the more southern Atlantic islands or in the Caribbean.. On down wind trips (most of our trips ) it did not give us enough as the boat speed reduced the apparent wind.. If you use one pay attention to the height as it has to be high enough to be sure there is no chance of the blades hitting anyone..Remember that it will be increasing your wind resistance while underway and the net gain will be very low if any.. In 2008 we added a 50 watt solar. From that point on the wind turbine only ran at night or on foggy days up north..Except for when we are running the radar we always have power and the batteries hardly ever get as low as 50% dod. If you have the option of mounting the turbine were you moor the boat and use the panels all the time that is mrecommendationon.. i think even a 400 watt turbine is too much stress for a 20 foot boat and too much weight too high up.
