Product Features:

This special swivel arm fitting has a series 50 alloy sheave incorporated in the arm construction. Only one cheek plate is fitted to this sheave which allows the mainsheet to be removed from the swivel arm fitting when sailing downwind. For upwind sailing when hiking the conventional cleating of the mainsheet in the swivel arm is used, but when sailing downwind the mainsheet is handled direct from the boom for more accurate control with the swivel arm fitting at this point being redundant.
