I need to equip a sailing boat for battery charging for a single
long haul trip of about 35 days.

Anyone care to comment on the Honda Generator idea?
Any other good ideas that I haven't considered or flaws in my
logic?

*If* you decide on a petrol generator shoving out 120v or 240v,
make sure the accompanying battery charger is a modern multi-stage
charger, capable of outputting up to 14.4v (for lead acid). Only
at this voltage will you be able to re-charge reasonably quickly.
Once the batteries are up to 70% or so, the modern chargers will
sense this and cut the charge voltage to 13.6v or so to prevent
battery overheating.

Many older chargers will only output 13.6v, and at this voltage
you will require hours of running to top up the batteries. Fine
when you're at the dockside . . .

Most petrol gennies which output a nominal 12v, will limit their
outpput voltage to 13.6 or less, so that won't help.

Drive that boat a bit faster with your main diesel!
