Fourwinds II unattended -- how much wind?
I have a sailboat that we use on weekends and 1-week vacations. I keep it moored in a place where the average wind speed is 11 knots, so using a wind generator makes sense. (Also it has a 6x1.5 foot solar panel on the davits that charges 2 large house batteries.)
I like the Fourwinds II -- have seen it on other boats at anchorages and it seems to spin quietly, and it has enough of a blade radius (blade-swept area) to be effective.
I work quite a distance from where it is kept, so I worry about any high winds damaging it, and maybe breaking a blade and shaking my boat apart with vibration after that. (I have a friend living nearby, but I don't want to call on him too many times to tie it up.)
Question: How much wind can the Fourwinds II (with speed limiter) really stand? Can I leave it spinning in anything but the well-advertised hurricane?
