The SD 35/15 is the smallest of three vessels offered by Shallow Draft Elevating Boats Inc. The 35-foot long and 15-foot wide vessel weighs 33,000 pounds. It drafts only 18 inches at 9,000 pounds deckload, and has a deck load capacity of 15,000 pounds in up to 4-foot sea conditions. A tunnel drive design leaves water bottoms less disturbed - no more dredging. The raised, clear deck space is surrounded by steel handrails and a host of other safety features.
