Low-profile mast base halyard lead blocks are lightweight and can be grouped in a small area at the mast base. Flared cheeks prevent chafe on the halyards.
Over-the-top blocks lead lines aft over cabin houses, coamings, and splashguards. They feature high-load sheaves and come in single, double, and triple configurations.
