I am about to buy an older Seafarer 22 sailboat and one of the many things that I am going to do it rework the power set-up on the boat. I want to install a small wind turbine to help with charging the battery bank. Would installing the turbine atop the mast be a poor idea? I thought that being up-high, it would be out of the way of people as well as get a better flow of wind yet I am worried about the weight. The turbines weight between 17-30 pounds.

hi,
I also have a seafarer 22. My concern with placing the wind turbine at the top of the mast is accessibility. if there is a malfunction, accessing the turbine would be problematic.
good luck,
ug

Personally I think that's an awful idea - not only would maintenance access be difficult, it would look hideous and it would be hard to sail: besides the weight, the added wind resistance at the top of the mast would heel the boat excessively.

A friend of mine put a windmill on his Cal20 by mounting a pole on the transom, which puts the blades away from the sailor and still allows easy access. He rigged a system so he can unplug and easily remove the turbine when he wants to race or just play - works pretty well. You might look at that idea.
