I use a motorcycle battery for around the bouys, just charging tacktick, vhf, then I switch to two 12 volt tractor size batterys for cruising, off shore. tiller pilot takes a lot of draw and I do some overnight races. I charge those off my mercury 5 hp outboard with alternator

:: Nothing special here.

:: Integral batteries/solar for buoy racing.

:: Larger central battery for longer stuff. When I bought

:: that had decent capacity... it still weighs far more
:: than I'd like.

:: Not LEDs yet either.

:: This is an area I can improve upon.

:: :: 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
