The A Scow is an American scow-hulled sailing dinghy that was designed by John O. Johnson as a racer and first built in 1901.[1]

The A Scow design was developed into the V38, by Victory by Design, LLC in 2005.[2]

Production

The design was initially built by Johnson Boat Works in White Bear Lake, Minnesota United States , but that company closed in 1998 and production passed to Melges Performance Sailboats, who continue to build it.[1][3][4][5]

Design

The A Scow traces its origins back to a Johnson-designed prototype in 1896. Over time the class has changed and evolved into essentially a one design class today. At 38.00 ft (11.58 m) length overall, the design is the largest scow raced today and is one of the largest dinghies produced.[1]

The A Scow is a racing sailboat, with the early versions built from wood and the more recent ones built predominantly of fiberglass. It has a fractional sloop with a masthead spinnaker. The hull is a scow design with a raised counter, vertical transom; dual spade-type rudders controlled by dual tillers and dual retractable centerboards. It displaces 1,850 lb (839 kg) and carries no ballast.[1]

The boat has a draft of 4.00 ft (1.22 m) with a centerboard extended and 1.00 ft (0.30 m) with both retracted, allowing beaching or ground transportation on a trailer.[1]

For sailing the design is equipped with an asymmetrical spinnaker of 1,200 sq ft (110 m2), flown from a retractable bowsprit.[1]

The design is raced with a crew of at least five sailors and normally has a total of six or seven crew members to help balance the boat.[5]

Operational history

The boat is supported by a national class club, the National Class A Scow Association, which regulates the class and organizes races.[6] The A Scow is mostly raced on lakes in the midwestern United States.[1]

A film was made about racing A Scows, The Ultimate Ride, by racer Peter Crawford.[7]

A review in Sailing World in 2006 by Gary Jobson, wrote, "these boats sail best when heeled more than 20 degrees, and in a breeze, it takes a lot of courage to do this. The boat rocks up and you feel as if you're about to be catapulted out of the cockpit. But a subtle tug on the tiller, a slight ease of the main and spinnaker sheets, and zingo, you're sailing at 25 knots. There's no crew weight limit, so depending on the wind strength, 5 to 7 crew can be piled on the rail with sailors rotating on or off in between races."[7]
