Dose anyone know anything about the sailing quality's of the 7.5M triple keel Achilles. I know their were only 3 of them molded and I think WHY? Why were more of them not produced. I know Chris Butler said he was sorry he didn't give more headroom in the 24; which is essentially what he seemed to do with the 7.5M a little longer a little higher. Dose anyone know anything about this boat?
