Other RC Sailing forums with greater usage
Please don't think by the level of traffic here in the Sailing section of this forum that there just aren't many folks interested in RC Sailing online.
If you head over to the American Model Yachting Association's website http://www.amya.org
and check the Model Yachting links page (linked from the home page) you will find links to some forums with over 1000 members and folks from every stage of the hobby, rank beginner to many times national champions in several different classes.
There are folks talking about multi-hull RC sailboats and hydrofoil RC Sailboats, International classes sailed around the world and in your neighborhood, folks who love to design and BUILD boats more than race them, and folks who love to race them more than build them.
