From Wikipedia: The STV St. Lawrence II (Sail Training Vessel) is a 72-foot (22 m) brigantine designed for youth sail training and is operated by a crew of 14-19 year-olds. It was designed in 1952 by Francis MacLachlan and Mike Eames, designed for the sole purpose of youth sail training. The hull was built in 1953 in the Kingston, Ontario shipyards, with the rest of the ship finished by local craftsmen, Kingston sea cadets and enthusiastic amateurs. When the St. Lawrence II first started out she was affiliated with the Royal Canadian Sea Cadets Corps St. Lawrence, but eventually her program was opened to any participants ages 12-18 for a summer training cruises.
The St. Lawrence II's home port is Kingston, Ontario. The ship sails mostly in the Great Lakes and the St. Lawrence River, but sometimes will venture as far as New York City. The success of the St. Lawrence II was the inspiration for the construction and launch of her Toronto-based sisterships STV Pathfinder (in 1962) and TS Playfair (in 1973), with both training vessels also being designed by Francis A. MacLachlan.
