sentences:  To keep up with the increasing demand for crab in the late 1980's and early 1990's, boats needed to carry more pots (steel box shaped traps that are used to fish for crab).Rather than buy a new boat, the Hansen family decided to have the "Northwestern" extended twice.Originally built at 108 feet (32.9 m) with the ability to carry 156 pots, the "Northwestern" was extended to 118 feet (36.0 m) in 1987 to allow for 200 pots.
