"St. Lawrence II" was designed in 1952 by Francis MacLachlan and Mike Eames expressly for youth sail training. Gord Workman and Grant MacLachlan were also key figures in the development and initial fund raising of what is today the longest running youth sail training organization in the world.

The hull was built at Kingston Shipyards in 1953 and she was finished by local craftsmen, the Kingston Sea Cadets, and enthusiastic amateurs, many donating their time. Originally attached to the "Royal Canadian Sea Cadets Corps St. Lawrence", her program was soon opened to other youth groups and now any teen, 13 to 18 years of age, can apply to join her crew for a summer training cruise.

The ship is built of all welded steel to very high safety standards, with an overall length of 72 feet, a deck length of 60 feet, a beam of 15 feet, and a draft of 8.5 feet. The rig is that of the traditional brigantine with square sails on the foremast and for-and-aft sails on the main. The total area of her working sails is about 2,500 square feet. She is also powered with a 125 horsepower diesel engine which will give her 8 knots under power. Electricity is supplied by a 12.5 kilowatt diesel generator. Navigation and communication equipment include GPS and VHF radio. There is accommodation for 25 officers and trainees in three cabins, separated by watertight bulkheads and doors.

In almost half a century afloat, the "St. Lawrence II" has shown her flag from Lake Huron to the north-east Atlantic seaboard, proudly representing Kingston and Canada in a number of exciting Tall Ship gatherings and special maritime events. The greatest of these adventures were "OPSAIL'64", "OPSAIL'76" and "OPSAIL'92", all in New York City, for the grandest of gatherings of tall ships from around the world. For her 1976 voyage to New York, "St. Lawrence II" had the privilege of accompanying her sister ships "Pathfinder" and "Playfair" of Toronto, down the St. Lawrence River, through the Bras d'Or Lakes, and on down the east coast. The "St. Lawrence II" was also at the 1984 gathering of tall ships in Quebec City to mark the 450th anniversary of Jacques Cartier's exploration of the St. Lawrence River. Later that year she led the fleet for the sailpast into Kingston Harbour.

Brigantine Inc. is committed to developing character through the adventure af tall ship sailing, and nurturing a sense of responsibility in all youths who serve on the decks of the "St. Lawrence II".
