The original design was 16'. There was a turbo edition that was 18' with a taller stick. At that time there was also a sport edition that had a 14 beam and a short rig, for the cruising minded with slip requirements. But then the standard boat became the 14' beam with the taller rig. This was described first as being able to raise the hull earlier and therefore faster than the wider beam (described to me as think of a large A-Cat), with a second benefit of fitting in a slip.

They will build you just about any config you want, but the standard for OD remains the 14' beam with tall rig.
