San Juan sailing IIRC has a all womens 1 weekend or a week once or twice a yr in about June or July. That program sells out fast! I saw it lst yr in the 48N yearly listing of schools, and it was sold out before the article came out IIRC. My wife had thought about that one. There is also a fellow in Everett that does class's. I know a couple of people that have done that one.
Neptune sailing club in Kirkland is another. Not sure how good they are today, I took lessons as a teenager in the 70's thru them via the Kirkland parks dept.
There is a dryland class Feb 23rd at north seattle comm college put on by Lattitude sailing that tenuki linked above. Spouse plans to be there again this yr. Luved the program last yr.
She drives me boat,
I drives me dinghy!
