Thanks guys. Teeing off of the vanity drain works. In my case I thought that, since I do not have fresh water heads, taking the water supply off of the head intake would also provide a way to help keep that line clear of stagnant sea water, which is a problem with that head. If I understand you correctly, the windless "shelf" is 2" thick fiberglass? I would not have thought it was that thick. I'm wondering if there is a windless back-up plate molded into the fiberglass as with the stanchions. What is the hole distance right or left of the windless that is a good measurement to miss any back-up plate that may be there? Also, how do you get access to the underside of that "shelf"? I would imagine from the V-berth? I haven't checked yet, but my assumption is that the windless lines run up from under the v-berth and should be accessible to run the water and electric lines.
