Abstract
A sailboat swivel base for supporting a block and a rotatable arm includes a central rotatable post for supporting the block and a separate annular bearing system, located axially outwardly of the post, for rotatably supporting the arm against bending movements that would otherwise cause distortion, undue wear, and sloppiness in the base. The separate bearing system comprises annular sets of rotary bearings in the base that confine and support opposite sides of the end of the arm, the bearing sets being carried in annular recesses between the arm and the base.
