Abstract
A roller chock for a boat. The chock includes an elongated base plate that mounts at the edge of a hull. A curved arm extends upwardly and aft to provide a smooth rubbing surface that is aligned with the general direction of a rode or other line. Spaced from the arm is a roller assembly having a top plate with portions extending forward and toward the center of the boat. A roller rotates with the line if it bends around the roller thereby to minimize wear on the line. The plate and the curved arm capture the line.
