Sailing Blocks or pulleys for a sailboat can have single or multiple sheaves such as single blocks, double blocks, triple blocks and quadruple blocks. Sailboat Blocks when fixed to the end of a line are used to gain mechanical advantage. The larger use of sheaves in a configuration, the higher mechanical advantage gained. Blocks are used from small dinghies, to keelboats, sport boats, big boats and Maxis. The three most common alternatives for modern blocks are: plain bearings, ball bearings and roller bearings.
