The Challenger Offshore SV-398 features a patented Duo-Delta Conic hull that provides an unbelievably smooth ride in rough water. Designed and engineered to be rugged, beautiful, functional and family friendly, this model features encapsulated stringers and bulkheads. The unibody construction of the cuddy and cockpit has each component molded separately and then bonded to the hull. Solid offshore engine cradle mounts have been designed to reduce stress on the transom and high-performance instrumentation is standard.
