The biggest disadvantage of this one is that you have to buy a Hunter!!
OK, just having fun, sailboats are very personal with regards to taste, but remember, I was able to convince Compac to install electric in a new 27!! And to me there is nothing like the traditional look of a sailboat with a real bowsprit.

There are also a couple to catamaran companies with electric/hybrid options.

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.

I love it when you lay it out for us. I'd like to throw in a few points
however. The Catalina 30 actually has a shorter waterline, its listed as
25', while the Hunter 27 has a full 27' waterline and the Hunter's
displacement is listed as about 7,600 lbs, while the Catalina weighs in

at

10,200. The current Hunter 27 really isn't in the same class as the older
Hunters of that length or the Catalinas. Its more of a stretched 25

footer

than a roomy cruiser.

Those other numbers won't dramatically affect what usually works out to a
lot of factors like how the boat is loaded, the condition of the

batteries,

and the weather and sea conditions. I wouldn't put it past them to be
quoting range and speed that assume you're sailing down hill:)

I would assume, but take this with a grain of salt, that Hunter and Elco
would have this set up very well optimized and worked out. They've both

got

extensive experience and complete control over every component so they
should be able to make a good show of things. We'll know as soon as

someone

on the list buys one, any takers?

David,

I ran some quick numbers to see if 20 miles at 6kts is reasonable from

that

battery bank.

214Ah @ 72V = 15.4kWh
80% depth of discharge = 12.3kWh usable...

So I would believe 20nm @ 4.5kts from specific info that you posted

from

Hunter. That is very good performance from an electric conversion of

this size....

Of course, these are all estimates based on experience collected here

and

with other electric conversions. Hunter's results may vary, the only
effective way to find out is to put one of their 27e's through its

paces.

Let's hope that someone here buys one and gives a detailed performance

and

efficiency report.

Fair winds,
