I suppose that I could do some calculations and research to see how to
charge it off the boat's 12 volt supply. Have you any thoughts on this
please.

Suspect you'll have to go to 120 vac and their charger. The newer ones
are 36v, 3 12v in series

Rethinking, it might be possible to charge them directly.

They're looking pretty good; much improved over the old ones I'd seen.
