10 or 11 feet should not be a problem with a Travelift suitable to haul your boat. You might have to remove the generator
from the pole but the pole should not be a problem. Mine is about 12 feet above the water
and I just take the generator
down when I haul. My boat is 39 feet. A wind generator
needs as solid a mount as possible, a pin and sleeve set-up might rattle a bit when the wind
gets up and the generator starts really spinning. You will not be able to guy this short section to prevent movement as the generator has to have the top 3 or four feet clear so that it can turn with the wind
. Go with the permanent mount. You can check out my set-up in the pictures section of this site.
