Abstract
A bitt with a freely rotatable line-handling surface includes a frame having a first side and a second side. The first and second sides of the frame each include first and second ends, and the first and second sides of the frame are substantially planar. The first and second sides adjoin each other at the first ends and define an angle therebetween. The first and second sides of the frame are arranged for being attachable to a surface of a marine vessel at the second ends of the first and second sides of the frame. First and second shafts extend outwardly from the planes of the first and second sides of the frame, respectively. The first and second shafts each have a longitudinal axis. The axis of each of the first and second shafts extends approximately perpendicularly to the plane of the first and second sides of the frame. First and second rollers each have an axis, and the first and second rollers each define a bore along the axis of the respective roller. The bores of the first and second rollers are each arranged for receiving the first and second shafts therethrough. The first and second rollers are rotatably mounted about the first and second shafts such that the first and …
