Spinlock A-symmetric Extension Silver With E-grip 600-900mm tiller extension with asymmetric grip and extra sleeve grip. Our extensions are designed for the hardest conditions: they help reduce the strain and increase the sheer enjoyment of helming a fast boat. Our Asymmetric extension improves helming performance in three ways: i) more feedback - for accurate and precise control ii) more mobility - maintains the best helming position for optimum trim and visibility iii) less fatigue - correct helming position reduces back pain and improves concentration asymmetric grip fits the hand better and supports the wrist- two handed helming mode lets the arms relax into a more comfortable, elbows-down position. Diabolo version:- Preferred by single-handed yachtsmen. A windsurfing style universal joint returns it to a vertical position when not in use. Fit E-DIABOLO accessory to upgrade a standard EA or EJ extension to this specification. |
