You might make it with a short rode
I just installed (last year) an electric windlass on my '79 H33. The anchor locker is plenty big enough, however, you're going to need to use a large tapered block to counteract the "slope". Another possible problem is that the rode then stores in the forepeak and there isn't very much room in there. I'm using thirty feet of 5/16" chain followed by two hundred feet of 5/8" nylon. I have to have someone below and hand-pack it into the forepeak so it will all fit. I'm giving serious consideration to shortening my nylon to one hundred feet, since I rarely anchor in anything more than ten or fifteen feet deep.Another suggestion, I found that a battery and battery box will fit forward of the windlass in the anchor locker. Just attach a small solar panel on the anchor locker cover, and you have a self suffient windlass system.
