Convert or replace Spinlock tiller extensions with a Universal Joint

  • Spare part for Spinlock tiller extensions fitted with diabolo joints
  • Alternative to the E-JOINT and E-JOINTGP universal joints fitted to EA and EJ tiller Extensions
  • Windsurf style universal joint returns the extension to a vertical position when it is not in use
  • Used by short-handed sailors to keep the tiller extension clear from obstruction while steering by autopilot through manoeuvres
  • Non-mechanical helm feedback preferred by some while hand steering
  • Stiffer E-DIABOLO/J minimises ‘waving’ caused by tiller and boat motion when tiller is in vertical position
  • Used in Mini Transat, Class 40s, Figaro, Open 60s and many other boats that are predominantly tiller steered by autopilot


Diabolo option:

Tiller extensions from the 900 series range are supplied with slimmer E-DIABOLO

Tiller extensions from the 1200, 1600 series range are supplied with ‘jumbo’ E-DIABOLO/J
