Back when, I made up a model of the fitting (using the one from 338) to the specs in the Manual and sent it off to Bristol. I got the new casting back and it turned out it was much wider that what Pearson had put there. Not that I couldn't have figured it out befor...

Because I had taken the moth-eaten original, bent the sides back out. They were bent in, I thought, by bolts, and bondoed the corrosion smooth. It was corroded on the side of the zinc. Anyway I assumed too much.

Ended up I had a bit of fairing to do on the keel.

Anyway, it says on the specs in the Manual the rudder shoe was for the Coaster and the Vanguard as well. Somehow, the original fitting on 338 had narrower scantlings. It wasn't all the fault of corrosion. You might want to get some owners to caliper the shoe befor you go into production. It just might be possible the shoe (on 338) came from one of the other Alberg.

What an assumption that would be:
That all Albergs have the same keel angle!!!
