Thanks for the response. On the beneteau there are no chains. Purely vectran line.
The vectran line has two eye bolts splice to the end which attaches to the quadrant. The line then heads away from the quadrant at horizontal level. It then passes through 2 heavy turning blocks making the line turn at right angles towards the binnacle! The vectran is then secured through the shaft of the wheel
. When you turn the wheel
gathers on the shaft and turns the rudder
These boats were designed for class racing
so made light as possible hence the light and feeble design of the steering.
Fraying occurs due to the tension required on the vectran line to ensure that it stays on the pulleys!!!!
