I've been looking at true sine wave inverters on eBay. 300 watts for about
$150. Could be good for the laptop as well.

Not likely. Your "cheap square wave inverter" is probably a "modified
square
wave" as well. I haven't had much luck with the typical hand tool NiCd
chargers with these inverters.

I use a 19.2 v Sears drill to raise the sail on my Nonsuch 26 and find
that the 75 watt 115 v charger does not function on the output of my
cheap square wave inverter. Would it work with a "modified square wave"?

Thanks for your interest, I guess I'll have to wait till I have shore
power since "true sine wave" inverters cost more than the drill, Dick
