Yeah, VoN. That's it. Looked at one (yellow hull) in Joisey. A little too
small for us. Don't they have more shear line than a 21?

Yes, they do... I have heard varying reports on this. One is that they bent the
hull mold with a chain hoist to make the VoN model. Another is that they padded
the mold around the transom with three chunks of plywood & some wax paper.
Probably only Roger Macgregor knows the truth. But anyway, the hull sections,
the rig, and most of the deck (they changed the cabin trunk a bit too) are the
same.

MacGregor is for sure not the only boat builder to do this. Lots of other
builders too. The Santana 23 has been reincarnated three or four times, always
with the same hull.
