Use of this crank is for experienced users only! The stainless halyard winch crank can be used to tension the rig as well as hoist the sails. Damage can be done to the winch box, halyards, and other rigging if the crank is turned the wrong way, or used to tension the rig too far. The stainless crank will not break before the winch box like the aluminum cranks. The stainless crank can be a valuable rigging tool – just be sure it is not being utilized by a novice Scot sailor. In addition, be careful not to keep your stainless crank stowed behind the digital compass in your stanchion. It will interfere with the compass headings.
