Mainsheet Controls 2016

Copernicus has an 8:1 4:1 mainsheet system, which use to be attached to a car on the mainsheet track just aft of the cockpit. But we found with the freestanding mast, the car did not move form the mid point; no need for the track or car. And we also had it on jam cleats, which were at times hard to release when under heavy load (read strong winds). So Bryan designed and built a control system using line clutches for the main sheet and threw in the preventor controls as well. Sorry I did not get a picture of the before for comparison. New setup works a treat!

    Laying Up B10

    Marina Carenero January 2016

  • Bryan laid up sheets of fibreglass; 4 layers of 2oz mat sandwiched by 3 layers of 22oz knytex on each side. We call this B10 (a spin off on G10). The mainsheet control would sit on a shelf made of this B10.

  • Upside down, and can see the sides and "top" are double layers of B10. The big square is a single layer and will be bolted to the back of the cockpit seat.
