How to build a wind generator for a sailboat?
Does anyone have good plans for a small 24″ three blade wind generator ?
Hi,
You can try this set of plans :

But it will be good if you spray a protecting coating on it for make it marine grade.
The following steps were taking directly out of that DIY guide I offer to those who would like to run their homes on wind power safely, reducing their monthly utility bills or even selling power back the electrical companies.
“This manual is based on using a 260 VDC, 5 A continuous duty Treadmill Motor with a 6 inch threaded hub. These motors are available for under $50 from most motor surplus stores. We are getting about 7 amps in a 30 mph wind. In other words, it is a simple, cheap little machine to get you started. ”
“ASSEMBLY
1.Place the motor on top of the square tubing & bolt it in, using the two 5/16” x ¾” bolts.
2.Place the diode on the square tubing, about 2” behind the motor, & screw it into position using the self-tapping metal screw.
3.Connect the black wire coming out of the motor to the positive incoming terminal of the diode (Labeled AC on the positive side).
4.Connect the red wire coming out of the motor to the negative incoming terminal of the diode (Labeled AC on the negative side).
5.Center the tail over the square tubing, at the back end. Clamp your tail onto the side of the square tubing.
6.Using 2 self-tapping screws, screw the tail in place.
7.Place each blade on the hub so that all the holes line up. Using the ¼” bolts & washers, bolt the blades to the hub. For the inner three holes, use two washers per bolt, one on each side of the blade. For the outer three holes, just use one washer next to the head of the bolt. Tighten.
8.Hold the end of the shaft of the motor (which comes through the hub) firmly with pliers, & turn the hub counterclockwise until it tightens & stops.
9.Screw the nipple tightly into the floor flange using a pipe wrench.
10.Clamp the nipple in a vice so that the floor flange is facing up & level.
11.Place the square tubing (and everything that is on it) on top of the floor flange & move it so that it is perfectly balanced.
12.Through the holes of the floor flange, mark the square tubing at the point of balance.
13.Drill these two holes using a 5/32″ drill bit. You will probably have to take off the hub & tail to do this).
14.Attach the square tubing to the floor flange with two sheet metal screws.
For a longer life span of your wind generator, you should paint the blades, motor sleeve, mount & tail.”
Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at www agua-luna com on the subject. I also offer online & on-site workshops, seminars & internships to help others help the environment.

At equilibrium a sail boat is moving with nearly the speed of wind. A wind generator cannot work in this situation.

I would not attempt to build a wind generator for use on a sailboat.
It has been my experience that the marine environment is so harsh that building something that can withstand it would be very difficult and also quite expensive. I would bite the bullet and pull out my wallet for a professionally designed and manufactured unit. I don’t see these for sale very often, but you might save quite a bit if you could find one second-hand - say from someone that was no longer cruising.
