I would say a 150% would be your first and primary racing sail, the extra power of the sail is well worth the rating loss of 3-6 seconds per mile. The 36T is a heavy boat and needs the drive to move in light to mid-strength air. Beating or power reaching in 15 knots of wind will put a BIG smile on your face. I would advise contracting with a local sailmaker for a racing sail, string or tapes IMHO, expect to pay $4500-5500. Use someone who will come out and measure the boat, if you have furling gear installed you can't count on the standard spec dimensions. Don't expect to roller reef the sail and race the resulting mess, get two reefs in a dacron main, that will cover you to the low 20's, the 36T is a very stiff boat (or do you have a mini-keel?).
Anyhow, if you get your boat even reasonably dialed in, you should be able to do a horizon job (they have horizons on the lake?) any day on a Catalina 36, regardless of who is driving it...
Certified...in several regards...
