Description

Harken 57 mm Ratchet Blocks allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing. It features Harken's Cam-Lock or U-Lock locking systems to lock the shackle in front or side positions, or swivel to keep line from twisting. The Harken 2140 comes with a triple sheave for max 10 mm lines and a camcleat and fairlead to secure and feed the rope when needed.

Comes with swiveling shackle. Use the Harken Triple Block for main and jib sheets on centerboard and keelboats like Lightnings, Dragons, Solings, and J/24s, and for mainsheet systems on catamarans.

Harken Ratchamatic, Carbo Ratchet, and Hexaratchet blocks are lightweight, strong, and run exclusively on ball bearings for fast trimming under any load.

Harken ratchet blocks hold part of the sheet's load, let you trim and ease with complete control, and enable higher trimming speeds. Ratchets make it much easier to hand-hold higher loads by only allowing the sheave to turn in the trimming direction. When you are holding or releasing the load, the faceted sheave grips the line to reduce fatigue and give you more control. Also, ratchets make faster trimming possible because you don't have to hold the full force of the sheet while shifting your grip.

Where should I use ratchet blocks?

Harken Ratchet blocks are great for any system that is normally adjusted by hand, including mainsheets, jib sheets, spinnakers, vangs, and backstays on everything from dinghies to large keelboats. In addition to increasing the loads you can manage without a winch, they reduce shock loading on your hands and your equipment for example, a ratchet block can stop an unanticipated gust from yanking the line through your hands or from putting too much load on your cam cleats. Some dinghies and sportboats even use two Ratchamatic blocks in series for turns less than 90 degrees per ratchet block.

How about holding power?

You can count on the Ratchamatic's powerful sheave geometry to hold your sheet securely, but still provide great trimming? feel?. Plus, you won't tear up your sheet playing the shifts in a blow.
