Very shallow beam, (don't really see it!) - no side supports at the cabin sides.

Lots of similarity to the Ariel of 20 years earlier - looks like heavier buttocks, to keep her from squatting. But the beamless interior is very interesting. Did you knock on the sides? They'd have to be solid, wouldn't you say? Otherwise typical Alberg. I have to wonder how it is done? maybe a single post really can act like a keel stepped mast. Do the shroud-plates come thru the deck?

Numbers say only 78 of these were built.

Hard to imagine any boat near the size of an Ariel with less than 3/16" wire.
Wonder how the general construction quality compares between the two?
