Interesting. I'm familiar with the history too. Friendships had a great reputation for seaworthiness, even back in the day. The one I know of that sank was an original I think, but racing in blustery conditions with topsails set iirc. I think the replicas that I've seen have about the same rig as the old ones, mine did.
You remember Schneider Pennant Sloops? My first keelboat was a 20' model built around 1961. I loved it.
