M_Boats: M15 Electrical System

I'm still trying to figure out the proposed electrical system in my boat, so I had a couple of questions for the gang. First, can someone tell me the stock layout of the components in an M15, i.e.. battery, switch panel, wire buss? Also, any interior lights, electronics or other components would be helpful. Second, is it possible to put to much weight forward in an M15? The smallest marine deep cycle battery (80 amps) seems to weigh about 50 pounds. I was thinking of putting the battery in the foremost locker just forward of the ballast bulge. I was planning on keeping my second anchor, chain and rode, 30-40 pounds, in that locker also. Maybe the answer to my first question will solve this issue. Thanks, Rick Langer M15 #337
