To make this worst IIRC, some have full keels, other a CB version! Altho the CB may not be a true Herreshoff design, but another persons take the hull etc and make it a CB. I'm also recalling a gaff vs marconi mainsail option too.
Look like nice little daysailers. Reality is, 20-25K for one, not bad when you look at a M36 for what, half a mil! talk about ouch! or a mil+ for the 42 or 52 versions. Have not seen a price for the 28 or 29' version........
