only one i knew who used genset underway was kharmaseas, the formosa 41 converted to electric motor...without concern as to how to charge motor while underway. he used 2 honda 2 kw generators. he had no solar nor wind generating capabilities.
most of us use engine in darkness to recharge batts as well as for making way.

Re: Honda Genset While Underway?
I do it all the time but not beating to windward. On a reach, if the oil level is kept high then 15 or so degrees of heeling wont trip the low oil level switch.
Works for me in any case. I probably generate under sail at least 6 hours/month in pretty sloppy conditions when coasting N.S.W. OZ.
