The Harken 57mm Ratchamatic High-Threshold Engagement (HTE) is our recommended solution for spinnaker sheeting in all senior skiff classes.  

The stiffer spring in this ratchet block delays the point of ratchet engagement, allowing the block to run freely for faster gybes. The HTE has a 15:1 holding power and suits ropes up to 10mm in diameter.

SkiffRopes recommends the 57mm Ratchamatic HTE for:

• 12ft Skiffs
• 14ft Skiffs
• 16ft Skiffs
• 18ft Skiffs
• 49ers
