Coastwise Corporation recently completed a landing craft design for Katmai National Park and Preserve in Alaska. The vessel is a shallow water roll-on/roll-off (RoRo) passenger and vehicle ferry. This new 65 foot vessel has a beam of 21 feet, travels at eight knots, operates with a crew of two and can carry ten passengers. It was designed to carry full size road graders, loaders, and tanker trucks. The vessel’s aluminum ramp is designed to load these heavy vehicles from un-improved beaches. Designated as a day-boat the ro/ro landing craft will operate June to mid-September and be hauled out of the lake, prior to freeze up. Fully loaded the vessel draws just over three feet of water.
