North American Fiberglass Sea Ox boats were over built to the hilt. The hulls were rock solid glass, and thick, and three-ply and five stringer designs. The Dual Console design had passenger and captain chairs as well as in front walk through design. The 18ft and 20ft Sea Ox dual console designs were a very popular model for many inland waterways, coastal waterways, and near shore ocean boating and fishing.
More coastal offshore fishermen are deciding that an agile dual console boat cannot be beat for combining seaworthiness, convenience
and fish ability. Recognizing this market, manufacturers are offering
some impressive new open water walk-around sportfishers.
One of the most impressive of the bunch are the 180D and 200D dual console designs. Among a field of tough competitors, both the 180D and 200D stand out in two respects: they are relentlessly seaworthy and its eight foot, six inch beam makes them about as much boat as can be legally trailered without special permits.
Sea Ox has built its name, literally as well as figuratively, on its strength since it entered the recreational boat market in 1977. Builder Graham Flanagan, president of North American Fiberglass in North Carolina, said he designed his boats to take on treacherous offshore waters off Cape Hatteras, where he cut his teeth as a young fisherman.
