I'm wondering what sort of battery systems people are running; specifically what type of battery, what capacity, and where are you putting it?

For buoy racing our only electrical needs are keeping the TackTick hull transmitter charged and we plan to use solar or AA's for that.

For offshore we will need to power nav lights (LED), a small GPS, and it looks like a fixed mount VHF too (which we don't plan to use much)....all for 2-3 nights. May add a tiller pilot too for occasional use.

I've still got to work out the current draw, but want to get some ideas of what others are doing.
