View Full Version : Anchor winch modification
Hi,
I'm currently sailing as captain on a schooner, and am working on a proposal to upgrade her anchor winch. She's a traditional type, carrying two 550 Lbs. kedge anchors on catheads. Both anchors use 3/4" chain which is stowed in deck boxes.
The anchor winch is a horizontal shaft mounted on the aft side of the bitt posts, with gypsy heads at each end. The actuator is a plain old teeter-totter rig.
I dislike this rig a lot. I hate how long it takes to range out two shots of chain on deck, and how dangerous it is to dump it all on the run when you let go the cat stopper.
I'd like to get rid of the gypsy heads, and replace them with wildcats. I'd also like to have a brake on the wildcat, so that the anchor can be released under control. That accomplished, it's possible to put the chain rode in a proper chain locker below decks, which improves stability and is easier on the deck (all that chain weighs a lot).
So, here's the questiion. Has anyone ever seen a modification like this, or know of a winch like it. We don't have room on deck for a vertical capstan, which is the only alternative to the teeter totter; we need to be able to get at least four people on the winch, and two of them had better be healthy specimens.
As a final question, does anyone know of a source of raw castings of 3/4" chain wildcats? Either iron or bronze would be fine. Or know of a machine shop in New England that has a big enough CNC milling machine , and enough imagination to undertake making a wildcat from blank?
And would anyone like to trade a 350-400 Lbs kedge with folding arm for one of our 550's? (If this looks an odious commercial offer, please delete it.)

Paul Luke can fix your gypsey problem. It just needs to be on a cone so it can be friction braked. Very safe to let out under brake control.
Like you, I don't really like the teetertotter and always imagined a worm gear alternative so'd would crew could either march around or crank.
Final thought. If there's the verticle space and a lack of sheets to foul a surpluss coffee-grinder with brakable gypsey under a drum is a super solution. You might have to locate the unit abeam or a tad abaft the foremast.
G'luck

Paul Luke sounds like a great lead.
However, FYI

New Found Metals should be removed from the above list. They haven't done custom casting for several years now, since the EPA forced them to shut down their foundry operation. These days they supply bronze and stainless ports and a few other stock items made in China. Port Towensend Foundry now has most of NFM's old patterns, along with thousands more I believe.

Thanks for the ideas. The tapered brake on the wildcat might work. I'd been thinking in terms of a disc brake, but will have to figure it out.
Last time I was at Paul Luke, they did not have a foundry. They supply patterns to a foundry that does the actual castings, and then finish the raw castings. I think that Spartan does the same. If they have a foundry there at Robinhood, I didn't notice it.
I don't think that the stop (ratchet) pawls on a coffee grinder are heavy enough for this service. We are talking about a 550 Lbs anchor and rode that weights over 500 Lbs per hundred feet. Aside from that, I can't see how you'd get more than two people on a coffee grinder. Two people can't lift that amount of weight in a reasonable amount of time between aweigh and hooked on the burton.
The problem with a capstan is that they need a clear circle around them for the sailors to walk the spikes around. A 90' schooner just doesn't have that kind of space. Maybe if we cut down the bitts, and put the capstan right behind the bitts. But then they'd have to step over the bowsprit butt every time they walked around, in addition to stepping over the chain.
Too bad, because years ago I got a very nice two-speed capstan with a wildcat off an old drydock in Staten Island that was about to be towed to sea and sunk. Although the wildcat wouldn't run backward, and it didn't have a brake.
Well, anyway, thanks for the ideas.
