The Searunner 37 is a seminal design in the history of multihull voyaging, representing the pinnacle of Jim Brown’s "Searunner" series of trimarans. Conceived in the late 1960s and refined through the 1970s, the 37 was designed specifically for bluewater cruising with a focus on safety, selfsufficiency, and "active" stability. Unlike many modern production catamarans that prioritize internal volume, the Searunner 37 utilizes a narrowv hull form and a central cockpit layout that places the crew at the boat's center of motion. This model was a primary driver of the amateurbuilding movement, as Brown’s detailed plans allowed many sailors to construct oceancapable vessels using coldmolded plywood and epoxy—a method later refined into the "Constant Camber" technique. The 37 is part of a larger family of designs, including the smaller 25, 31, and 34 models, as well as the larger Searunner 40, all of which share the trademark cutter rig and centerboard configuration.
