M_Boats: M-15 mast rake

Just out of curiosity, is mast rake a static setting, or should it be changed with the wind conditions? BTW, I though the SCA review missed the mark with the rudder comment. Otherwise it was a good review. steve Steve R. M-15 #119 Lexington, KY Jerry Montgomery wrote: ... I always thought the 15 had a terrific rudder. I guess I never read the review, but maybe the boat that they used was in a poor state of tune; blown-out sails or a mast that was raked too much. ...
