Harken Ratchet and Ratchamatic Blocks

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

Available Products

Harken ratchet blocks are available in sizes 40mm, 57mm and 75mm from Sailing Chandlery. There are two types, the standard Harken carbo blocks and the new Harken T2 lightweight design.

40mm

57mm

75mm

Let customers speak for us

from 710 reviews
Good price and quality

These are surprisingly difficult to find in chandleries which is surprising as they’re very useful for attaching boat hooks/deck brushes to the handrail. Low tech but good quality.

Good product, prompt delivery

Good product, prompt delivery. I've tried various options for securing the clew to the boom but none are as effective or easy to release as this strap.

ZHIK MICROFLEECE HIKER WETSUIT

Best spring/summer hiking wetsuit.

As per usual the Sailing Chandlery team got these to me in a flash! Amazing service!!!
I have previously used the Superwarm version of this hiker and it was brilliant!
I purchased these as I get far too hot in my winter hikers during the sweaty summer months!
Only used once so far, but were warm enough in 15 degrees C and worked exactly as expected!

Easier than fids in small diameter rope

Good size handle, comfortable grip. I find I have to go down a size in needle than that advised for the rope I’m splicing.
