David,
At Coasters Harbor we have a fleet of Rhodes 19s and Shields that are owned by the Navy and supported by the Morale, Welfare and Recreation (MWR) committee. We give training with both ground school and on the water instruction. People then take a written and practical sailing test and are issued qualification cards they show when they want to rent boats. Look on the
CHNYC web site and on the left menu click on sail training and the submenus. We post training material there.
Our costs are listed in the marina brochure available at that link.
