Do you need a switchable Harken ratchet block or a Harken automatic ratchet block? We look at the difference between the popular pulleys and help you choose which is best for you and your boat.
There are three options available for Harken blocks:
No ratchet - just a simple pulley or block
Switched ratchet block - you are able to flick a little switch to turn the ratchet on and off easily
Ratchamatic/Automatic ratchet block - the ratchet will kick in automatically based on the load going through the block
Why use a switchable Harken ratchet block?
Can we easily adjusted (on or off)
Great if people with different strengths are sailing the same boat
Can we changed for different wind conditions
Why use an Automatic/Ratchamatic Harken ratchet block?
Best for skiffs and trapeze boats where you can't easily switch a ratchet on and off
Great for gybing where the pressure will be released allowing the ropes to freely run through the block
The point of where the ratchet engages can be adjusted using an allen key which comes with the ratchet block
