The new OS 405 replaces the OS 385 and brings with it many significant upgrades, including a single-piece, optically clear, laminated safety glass windshield for an unobstructed view. Also new is the bottom design with 20 degrees of deadrise at the transom, aggressive bow entry and reverse chines. A Yamaha Helm Master EX joystick, autopilot and 4-hp bow thruster come standard, as do twin Stidd helm seats on the bridge deck. The port seat is elevated to improve sight lines and it swivels 180 degrees. Aft, a dinette with facing lunges converts to a berth. The OS 405 is powered by triple 450-hp Yamaha XTO outboards that push the boat to a top speed of 55.1 mph at 6000 rpm. At a cruising speed of 28.5 mpg (3500 rpm) the boat has a range of 317 miles. The OS 405 goes from a standing start to 30 mph in 12.6 seconds. Sipwake interceptors help keep the boat balanced and a Seakeeper 6 gyroscopic stabilizer smooths the roll at rest and slow speeds. Fishing features include a 50-gallon recirculating live well, a refrigerated transom fish box and tackle storage. Other cockpit highlights include a hullside door and two aft-facing seats. An entertainment center comes with an electric grill. One of the biggest upgrades on the OS 405 is below, where the forward cabin has an island berth that converts to a lounging position. The aft cabin is made private with a door. The foredeck has integrated convertible lounges and an optional sun shade.
