Larry, I agree having the battery forward of the mast works perfect for me. I think 2 batteries would be overkill for my purpose since I don't do a lot night sails. I only use mine mostly for depth gauge and knot meter. I can go a long time between recharges. But hey, whatever floats your boat (better trimmed). I am a "get in and go" kinda of guy so I don't worry about going faster, just going is good for me.

According to Jerry and the speed guys, the rule of thumb on both the M17 and the M15 is get the weight as far forward as possible. You want to have the transom out of the water as much as possible for good boat speed, as it causes drag. 3 inches seems like a lot, but you're carrying a lot of battery weight there. Are you using an electric motor? If you don't have an outboard hanging on the transom, that would explain the difference in trim. I wouldn't think you'd want to move the weight much further back than the mast support.
