I put one in my 336. Search the photo forums for "windlass". There are lots of ideas in there, and my installation as well.I built a very sturdy wood frame in the anchor locker to support the windlass, then gelcoated it white.Then, I bought a piece of aluminum tubing to run from the windlass, through the floor of the anchor locker, down to the space underneath the vee berth, where there's enough room for a chain rode to stack. I glassed this tube in to make the anchor locker watertight.I bought a windlass with a capstan, mounted it on the wood frame and cut a hole in the anchor locker door for the captstan to stick up through. If I had it to do over, I would have passed on the capstan and mounted the whole thing down inside the anchor locker on the constructed frame. The capstan has been very useful (going up the mast is a breeze now) but dealing with the modifed anchor locker door was a huge hassle. Not worth it.In the 35.5, there might be a little room just forward of the vee-berth bulkhead, if so you won't have to have a tube running by where your toes should go. The 336 is quite a bit smaller in front.Others have done well using PVC pipe instead of aluminum for the hawsepipe. I thought that the chain might damage the PVC, but I think that PVC has been proved by others to be servicable.Oh yeah, I had to drain the chain locker to the bilge, Hunter just thought this area was lost space and didn't do this.Good luck, it's a big job, and you'll end up with lots of new skills. Figure the windlass will be half the cost if you buy from a good source (Imtra on eBay comes to mind). The rode and electrical cables will constitute most of the remaining cost.Paulsv Escape Artisth336
