I dont think you need a deep cycle battery at all.

I dont think you need 2 batteries.

I think you need one quite small battery, like a 55 amp hour one. I dont know what they call them in the USA. But one small, good battery. Walmart or some other large auto store brand battery should be fine.

I just looked up a thing and it said Group 29 is 115 amp hours. I really dont think you need anything like that whatsoever. I suggest HALF that size.

For your overnight trips , as you say, take a camping lantern etc. If you sail overnight and the battery gets low just bung on the engine for a bit and charge it
