Advice Needed, Installing Fourwinds II

I am the proud owner of a used Fourwinds II wind generator. Now how do I mount it on our Beneteau 50? I'm thinking about using the typical 3-legged method, where 1 leg is vertical, the 2nd goes foreward, and the 3rd goes across the stern. Where do I get the brackets for the deck (2 of them) and for the transom (1 large one)? And where can I get the stainless poles that go into the brackets? (And the fittings that tie the legs together. And backing plates for the deck brackets.)

Am I missing something here? Or will this be reasonably easy. Any other advice welcome.

Regards

I bought a used fourwinds 2 for my previous boat, and the pole mounting was very simple to do. I followed the very clear instructions to the letter and never had a problem with the mounting in five years. As I recall I bought all pipe and fiittings from a large local hardware store that specialized in industrial surplus.

Do you have or have you ever wanted to install an arch in the back of your boat?... It seems by the time you are done with this installation, you'll add enough tubing and such around your cockpit that you may - for slightly more $$ - be able to have an arch that can contain the wind generator, bimini, radar and - some styles - dinghy davits even... Just a thought; since you will end up spending money on a mount anyway.

Isn't it fun to spend others' $$$?.. Let me tell you what "you" need....

SailnDive,

We do have dinghy davits. Not sure about all the weight, with a dinghy and all. Here's a picture with my son's 8' sailing dinghy on them. What do you think, considering an 11' inflatable with engine?



Regards

When I was doing research on my boat following the purchase, I discovered that a radar arch was an option. The B461 and B50 are very similar in dimensions, it may be worth finding out what it looked like. These are typically pretty beefy (like the sportfishing tuna towers) and should work well if they came with a davit attachment as far as handling the weight is concerned.

Even if you don't purchase through Beneteau, if you know what the general design looks like, you can have a marine welder (the sportfishing folks again) can manufacture one for you to your liking. You don't necessarily have to have the davits integrated, you can continue to use your existing set up; arch can accommodate that. I would move the bimini to be a part of the arch, though - not only does it look better but has a lot less clutter.

It seems we have the same (Marshall design, I believe) davits: I cannot deploy my swim ladder when the inflatable (a 10.8') is hanging on the davits - I think this is a safety concern in case of MOB situation. One of my upcoming projects is to convert the (existing) ladder into a folding one so that it clears the dinghy when swinging down and into the water. Should be a simple project (famous last words )

Cheers!

Sailndive

One thing to keep in mind, is the fourwinds has a propellor wingspan, or at least it did on mine, of about 60" and the blade speed could hit some insane mph's. You don't want to have that unit spinning anywhere near where people would routinely be climbing.

Yes, I tell the crew that if there's a MOB to just cut away the dink. (We can always get it later.) I like your idea better. Please let me know how it goes.

Very true. It's needs to be up high. I think the manual might have something about that. IIRC they wanted the shortest adult to be able to reach the blades (for tying off). And it needs to be a certain amount higher than the tallest person. I'll probably err on the side of it being higher. High speed spinning things scare me. (At least there's no strobe around to camoflage the spinning motion.)

...and, be careful with fishing rods, boat hooks, MOB poles anywhere near it My windbugger chewed up the tip of an expensive trolling rod with a very impressive fish on... the fish kept getting larger and larger over the years...

Did you end up getting this all straightened away?
I'm interested in the Fourwinds II wind generator and would like your take on it's output when the wind is not that strong.

Warm Regards,
Extemp.
