These are the tall rig standard draft and will give you a starting point. Try emailing Gerry Douglas at Catalina for the standard rig deep draft

Best spec in that linked 1979 review is the boat's PRICE PER POUND. US$2.21

I thought I had checked out every page of that site...but usually it is about fixing leaky windows & busted rudder post stuffing box repairs instead of actual performance numbers...
NCL - I own hull #511. STD rig, deep keel, w/ original Atomic4. Oh, I see those numbers are with a folding prop...I also have added the 3 blade 10 x 7.4 Indigo prop..although with no offense to its designer Tom Stevens, I probably would not do so again if I hadn't gotten such a good deal on it....a 12 x 7 2-blade which was stock on my boat or even a 12 x 6 might be adequate with much less sailing drag. Anyway..I digress...I do not race the old girl & I get another 150 RPM with the Indigo prop.
What do you own?
Go the CA!

Polars from an old square rigger?
Since people are asking how I drew that (!) no, I did NOT make that up.
Google Sail Polars.
There it is...
