The Irwin 37 Competition, frequently referred to in racing circles as the "OneTon Momma," represents a pivotal moment in Ted Irwin’s design career where the pursuit of IOR (International Offshore Rule) silverware converged with the brand's reputation for voluminous accommodations. Launched in 1973, this model was a departure from the centercockpit cruising focus of the standard Irwin 37, featuring an aftcockpit configuration, a highaspect masthead sloop rig, and a deep fin keel. While the cruising variant was often rigged as a ketch for ease of handling, the Competition was built as a focused OneTonner, intended to compete in prestigious offshore events like the Southern Ocean Racing Conference (SORC). The boat famously served as Ted Irwin’s personal racing platform, most notably with his yacht La Pantera, which secured second overall in the 1974 St. PetersburgtoMexico Race.
