so I suppose people do install them on sailboats, its just that I've never seen one this size....I always see the Air X or the Air Breeze units that run about 400 watts and about a 50" diameter blades.
Thanks for any and all comments.
Apart from structural issues you might want to consider gyroscopic and aero acoustic issues. These will be the limiting factors.
The problem with wind turbines on sailboats is where we typically mount them. If we could practically mount them on top of the mast
they would perform much better and have a more effective duty cycle.
In the dirty air near the deck
smaller wind turbines will start producing power at lower apparent wind speeds. They do of course lack the top end power of a larger unit.
There is also the aesthetics to consider. Would the larger turbine look suitable. This is purely subjective but is what drives many peoples acceptance of something different.
We are actually considering adding several smaller wind turbines in place of our large fourwinds. Heterdynoing can become an issue.
