The particular configuration adopted permits the use of large diameter sheaves which improve performance of the system; it also ensures maximum block orientation capabilities and therefore the possibility to operate on both sides of the boat. Furthermore, this reduces the necessary sheet length.
The two speeds are controlled by means of two independent lines.
Main sheaves (Ø = 65 mm) are made of HRM resin and fitted with a double ball bearing.
For rope Ø = 12 mm
