The only bad news isn't all that bad. You'll need to spend a bit more money
for 3/8 chain. That would also include a 10mm in a European Windlass. I have a Vetus Alex III 10 mm on my CSY 33
and it's a serious weapon. Other boat has a free fall SL that is much slower. I would want if I had my choices:
1. Electric Up and down and it should be fast!
2. Controls on the fore deck
and the helm
. I had both deck switches and a wired remote
and a toggle at the helm
on the CSY
and there were times I used them all.
3. A manual option so you can ratchet the chain back up by hand. I've done it twice. I don't know of any that don't but I would consider how easy it is to be a factor. None will be as good as the Sea Tiger
in manual mode.
You'll want to maximize the free fall. The last boat didn't have as much room as I would have liked and the chain would cone up and then the gypsy loses it's bite. Then you go below and knock the cone down and continue. After enough times of this I just stopped half way up and went below and knocked it down and the restarted. Seemed to be less frustration.
My guess is the hole patterns will be close but not exact. You may be better off to patch the holes and make new ones if you have something solid to attach to. You really do want a very very solid attachment point. You may want to extend outboard
above or below the deck to make a really solid attachment. I would avoid a "box" type arrangement as they won't be very strong.
Each unit will tell you how perpendicular the chain needs to be coming in but it must exit straight down as the weight of the chain in free fall keeps the chain on and in the gypsy. If not the chain jumps up and the gypsy slips. It makes noise
and the instinct to reach out and grab it can be a dangerous move.
