Spinlock's EA Tiller Extensions are telescopic and have an asymmetric grip to fit the hand and support the wrist on or off the wind. This grip enhances control, reduces back pain, improves concentration, and enables the helmsperson to steer from the optimum position for trim and visibility. It comes with a Diabolo Universal, which is preferred by single-handed sailors, because the windsurfing-style universal joint returns the extension to the vertical position when released, making it easy to find. The extension can be released quickly from the tiller for stowage.
The EA/900S comes in silver and is 23 5/8 in. (600mm) and 36 in. (900mm) long when extended.
