Sailboat Ratchet Blocks
Ratchet blocks significantly improve performance on hand controlled lines. Ratchet blocks allow you to trim and ease sails more easily and with more control. A ratchet block works just like a ratcheting wrench, it allows the sheave to turn in only one direction. Most Ratchet blocks have an on/off feauture to allow them to also work as a free rolling block. New Ratchet blocks from Harken and Ronstan (the Harken Ratchmatic and the Ronstan Orbit Blocks).
About Harken Ratchet Blocks
Harke Carbo Ratchet blocks are 60% stronger and 30% lighter than the classic Hexararchet blocks. he nylon resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Ball bearings, sheave, and sideplates are UV-stabilized with carbon black for maximum protection. Harken Carbo Ratchet blocks are available in 57 and 75mm sizes and have an on/off switch for the ratcheting feature.
Harken Carbo Ratchmatic blocks are load-sending ratchet block that rolls freeling in both directions under low loads and automatically engages the ratchet as loads increase. Shifting between ratchet and light-air modes is seamless with the Automatic Ratchmatic blocks from Harken.

Harken Ratchmatic automatic ratchet blocks are available in 57mm and 75mm sizes.
