Harken 57mm Ratchamatic® HTE 1.5x Grip Block

Description

Harken 57mm Ratchamatic® HTE Block — Swivel, 1.5x Grip

The 57mm Ratchamatic® HTE isn’t just a block — it’s a performance upgrade for sailors who demand precision and control in dynamic conditions. With Harken’s load-sensing ratchet technology, this block runs free under low loads for minimal friction, then automatically engages as the load increases — no toggles, no hesitation.

The HTE (High Threshold Engage) version is tuned with a stiffer spring, delaying engagement so your sheets run clean during hoists, drops, and acceleration. When the power comes on, the 1.5x grip delivers up to 15:1 holding power, giving you control without killing feel — exactly what you want for sharp boat handling under pressure.

From downwind kite work to mainsheet control in heavy breeze, this block is a favorite among top dinghy and keelboat teams worldwide.
