ABSTRACT:
The improved crab pot line hauler's drive motor, sheave and associated line guide means having a common support are mounted as a composite unit on pivotal support bearings that permit the unit to revolve freely about a fixed bearing axis in addressing itself to the incoming line being hauled and that restrain the unit against other bodily motion. Placement of the center of mass of the hauler unit at or closely adjacent to such pivot bearing axis assures its relatively steady orientation in operative relation to the incoming line with minimal line deflection force acting on it to do this. Polar moment of inertia about such bearing axis being also made relatively small by such mounting system, quickness of response of the unit to changing line approach direction is also achieved, a major advantage in stormy weather.
