Good idea to put in a windlass. I really liked mine. I felt that the bulkhead was strong, and used large (thick) stainless backing straps to spread out the load. On my brother's Cat 36 the bulkead was less well attached (go figure), so I put two large teak pieces, then the stainless backing straps. No engeneering calculations, just looking at the way the bulkhead on the 34 was solid and well tabbed to the hull. I think that 2nd Wish and I have similar pieces, I just wanted to add a bit of room on the front end for an anchor snubber - which worked well for me. I made up a cardboard mock-up to be sure it fit my anchor locker. Yes, in addition to the up and down switch, I also put in a rocker switch at the helm station. Easy to do when installing the unit. I found it useful, but most of the time I went forward anyway. I chose not to put in a dedicated battery to save weight. My batteries were in the area forward of the dinette, so large wire (forget size now, sorry) made it work. Never had a problem, but might if I was out for an extended time? Hope these thoughts help. Good luck with your project.
