There are many commercial uses of our pulley block and tackle products, as well as replacement sheaves, bearings and bushings, such as:
Boat Docks • Boat Lifts • Boat Rigging • Yachts • Model Yachts • Commercial Fishing • Sails and Sail Boats • Trailers • Yachts

Pulleys on a boat are called blocks (as in “block and tackle”).  They are used anywhere you need to change the direction of a pull on a rope, and also to create a mechanica advantage.  Pulleys are used in sailing because of the amount of force that is needed to change the shape of the sails.  For example, to hoist a saile up a mast, the halyward (rope to hoist the sale) will pass through a block at the top of the mast so that while standing on the deck, you can pull down on the rope and the sale will go up.
