3T V Sheave — Wide Tulip

Harken 3T V Sheave — Wide Tulip

The Harken 3T V Sheave — Wide Tulip is a premium high-load titanium sheave engineered for performance sailing applications where reliability and efficiency are paramount. It incorporates the same proven bearing set of angled titanium rollers found in Harken's renowned V blocks, delivering incredibly smooth operation under load.

The versatility of this sheave makes it a go-to solution across a wide range of onboard systems. It excels when running lines underdeck, within mainsheet and spinnaker sheet systems, and in drop line configurations. It is equally well suited to rigging clean backstay systems, helping to steady today's slender masts and provide precise control over mast bend.

The wide tulip ("Wide") profile sets this sheave apart from narrower alternatives — it is specifically designed to handle a range of load angles without compromising performance, and is the preferred choice for two-sheet peel maneuvers. This makes it an essential component on race boats where fast, reliable sail changes are critical.

Snap-fit Delrin® side covers require absolutely no tools to remove, allowing fast, straightforward access for routine inspection and maintenance. Delrin® is a registered trademark of E. I. du Pont de Nemours and Company or its affiliates.

At just 174 g, it adds minimal weight while providing outstanding strength and longevity.
