Hmmm. I just checked the Hunter website and it says the Hunter 27 waterline length is 23'7". But that's just a minor detail... It doesn't change the general results much.
Ah, yep I see. I was going on the numbers published by Sail in their little write up, they've got the hull length that Hunter lists as the LWL and don't make mention of the LWL from the Hunter spec. Either way, its still got a pretty good water line for its LOA, of course all that changes once you start heeling or loading it down. I seem to remember a few years ago them selling a Hunter 26 that was the same boat but with an outboard instead of an inboard and some pretension to trailering, but I may be fuzzy on that. I do remember sailing our old '77 27 into St. Augustine coming back from the Bahamas and one of the brand new Hunter 27s sailing by us and asking us where we'd been (the Q flag was up and we had clearly been 'out there' for a while.)
But we're obviously on the same page. BTW, the Elco drive certainly looks sturdy, I wonder how much that unit weighs. There's a picture on the ELCO 27e brochure that is linked to the Hunter 27 spec page on the Hunter US website.
It looks like a serious little drive doesn't it! I'd really like to get a look inside that case.
