More information on Blocks & Accessories:
Sailing blocks are one of the most essential pieces of hardware on any racing or cruising sailboat. They can be a single or multiple sheave pulley between cheeks. Lines run through blocks to create purchase systems or change the direction of the rigging or line. From dinghies to keelboats, they are needed to perform many of the necessary tasks of a crew.
Blocks come in many makes and models. Sailing blocks come most commonly in single, double or triple sheave formations. Next, there are traditional or high load blocks, rated by the block's safe working load. Lastly, there are different configurations and attachments for sailing blocks. Beckets, cheeks, fiddles, hexaratchets, ratchets, snatches, loops, dyneema loops all determine how the block might be used. The structure and sheave can also vary widely from ball bearing, aluminum sheave, ratchet, to snatch. From high load to low load applications, sailing blocks perform essential functions on your boat.

Ball bearings provide fast running and smooth trimming of the lines.
Keep your deck organized and optimize your boat for racing or short-handed cruising by leading all lines aft to the cockpit.
Line feeders provide a fair lead over a hard edge like a coach roof.
Lightweight and maintenance free – great for any application not requiring a ball bearing block.
Simple and robust – used when more strength is required and at a more affordable price.
Manual or Automatic ratchets provide holding power to handle loaded lines making for easier trimming.
Replace worn, cracked, or UV damaged sheaves or mast boxes to keep your blocks running smooth.
Snatch blocks can be positioned on the fly and have nearly infinite uses.
