I run a NUC and a few other things off a 125W elcheapo $20 bestek(?) inverter off the house battery.
Sure it gets converted twice but the juice is cleaner in the end.
And consider DIYing a big house battery. The cells are cheap now. I built a 1200Ah LFP bank just because it fit nicely in the compartment. Then throw some solar at it.
And for backup, just get a large spinning external and plug it in occasionally to sync a copy. Put it back in the Tupperware for cold storage.
Sailing pleasure vessels take advantage of hurricane winds when traversing distances.
Not so much in close proximity usually, though racing sailboats certainly will.
