Bill,
I can guarantee that a wind tubine that will fit on a boat will not produce 1500W at 3 mph wind speed. The problem is that people that are promoting something will say things that sound different than they really are.
Here's an example: my car gets 35mpg, and it goes over 100mph, but it does not get 35mpg at over 100mph.
It can be difficult to figure out what is really true about or even old products. Your best bet is to listen to what people here have posted about wind power generation in the last week. Both Myles and Mike have already discussed this concept in detail.
Fair winds,
Eric
