The Mobjack is a doublehanded dinghy that was developed by a sailor and gunsmith, Roger Moorman, at Virginia's Fishing Bay Yacht Club in 1954. Moorman roughly based the Mobjack's hull on the hull of the Thistle but built it in plastic (i.e. fiberglass) as part of the postwar revolution in production materials. Five years later, the Mobjack-which had earned favor for its self-bailing capability-boasted membership up and down the East Coast and into the Midwest. Sailed without a trapeze, the boat initially required a crew of three, until the 70s when the single trapeze was accepted. The boat is 17 feet long (5.2m), with a shallow draft, and accommodates as many as eight people. It is still raced in Delaware and on the Long Island Sound and, especially, at home on the Chesapeake Bay, where it has not gone out of active racing in almost 50 years.
