Its in the forward V-Berth under the boards on Starboard
I have a pretty small battery and just charge it 2 times a season ,I finish a lot of races in the dark and as the nav light only draw 30 watts i have never had and issue.
Uhhh, it could be anywhere
If the boat's ever been raced seriously it'll likely be under the port bunk as far forward and toward centerline as possible, and the engine will generally be stored under the starboard bunk with the power unit forward.
Battery up front like that will be dog slow compared to a position roughly over the keel and balancing out the engine.
Keep weight low, keep weight out of the ends of the boat
