Larry The rudder on the 15 is plenty big enough. Alina was a Montgomery 17 that had a slightly different foil shape; I don't think it was longer at all. If so it wasn't something anyone should worry about. M_15s and M_17s in stock form have won the SCA Cruiser Challange many times. Bob Hughston, Larry wrote:
Re: "Big Rudder" on the M-15. Where do I find a big rudder for an M-15? I hope somewhere in the Sacramento Valley or San Francisco Bay area. Can this rudder be hand made at a home shop? ---Larry (wannabe M-15 owner) Hughston <larry.hughston@dgs.ca.gov>

"Alina" has a Jerry-Montgomery-modified rudder . . . I think deeper and more foil-shaped . . . And a carbon-fiber boom . . . She must be the fastest M17 sailing . . .

Hi, Doug!
I don't have the sweet spot figured out; John or Jerry or some of the others could give you a much better answer, but Miss T's mast is significantly raked aft more than Busca's and she knocks Busca's socks off to weather, even with reduced sail and the windage of a bimini.
The 17's big rudder is important as a lifting foil and takes some of the load off the keel which, not being a deep fin loses out some in efficiency.
At some point you can over-do it though, and end up with a loss in performance.

Tod,
I agree with your 10 deg opinion altho it could easily be 15 deg in some conditions.
What is this about loading some weather helm into the equation - I always thought a slight weather helm to neutral was best to avoid rudder drag!
Are you saying that give all other trim to be optimum that a moderate weather helm helps you point better than a light weather helm?
Thanks
Doug
