The Open 5.70 stands as a definitive bridge between the high-octane world of performance dinghy racing and the stability of a fixed-keel sportboat. Designed by the esteemed Jean-Marie Finot of Groupe Finot, the vessel was originally brought to life by Phileas Boats in France before gaining significant traction in the North American market through Open Sailing Inc. and later production by Hobie Cat. The design philosophy was centered on creating a boat that could plane easily, remain manageable for a crew of two or three, and be simple enough to trailer behind a standard vehicle. Its 18.7-foot hull is characterized by a powerful beam carried well aft and a modern, square-top mainsail configuration that signals its racing pedigree. Unlike traditional keelboats of its size, the Open 5.70 lacks a heavy, deep-displacement feel, opting instead for a lightweight fiberglass sandwich construction that favors "surfing" over "plowing."
