Worse yet, it is stored all winter with no charger,,,
Clearly this is the worst situation you can subject a battery to, so whatever I choose needs to be super resilient.
Thanks!

I would be looking at a dual purpose AGM battery with the highest CCA and AH capacity. The main reason I recommend AGM is their rate of discharge is half of that of a flooded Battery at only 3% per month as compared to a flooded (lead /acid) at 6-7% per month. Since you have no way to trickle charge this would be a good benefit to you in my opinion. They can also take the pounding a boat gives better and are completely maintenance free. Optima and Duracell are two brands of AGM I have used with excellent success.
