A bearing block has a head, a central hub, bearing means facilitating rotation of the sheave about the central hub. The block further has locking means for removably locking a length of high strength, fibrous material, such as cord, to the block for tethering the block to a boat deck or the like. The locking means may be a part of the block head, cheeks, or may be located at the block central hub. Preferred locking means are a plurality of passages for the cord ends to pass through, with set screws in two of the passages for removably holding the cord ends therein. A center portion of the cord length thus forms a loop for tethering the block.
