Harken Carbo Ratchamatic Block HTE 57mm, Double Grip

The Harken Carbo Ratchamatic HTE 57 mm Double Grip (Power3) is a load-sensing ratchet block for strong winds. HTE stands for high-threshold engage: a stiffer spring keeps the block free-running for longer, so the ratchet only engages at higher load. The silver-anodised sheave gives a 20:1 holding ratio – with 100 kg on the sheet you hold just 5 kg.

Features

• Runs freely in both directions at low load
• HTE: stiffer spring, ratchet engages only at higher load
• Clean, seamless transition; engagement load quickly adjustable
• Silver-anodised Double Grip sheave, 20:1 holding ratio
• Sideplates in high-strength, lightweight Carbo composite
• 2x Grip: for big, steady breeze
• The ratchet engages only at higher load, so the old kite sheet runs free for cleaner gybes
