Karver Tips

• There are 3 3:1 friction sheave references for each model:
• PF317 150: to replace a KSnap with a 3:1. To install directly during the preparation of the order, we then deduct the price of the KSnap.
• PF314 150: to order a 3:1 only
• For the most demanding racers we always offer the 3: 1 large in a half moon shape. It is more compact, more stable and more resistant. It can be made in titanium on request.
• If the 3:1 is used in 2:1, be sure to secure it with a small rope. Once detached from the furler, nothing prevents it from falling into the water.
• The KSnap which is fitted as standard on the Standard and Classic versions is a 2-in-1 snap shackle with a 2:1 function. In many cases, this configuration will be enough.
• The precursor is Karver: the first to design and market this type of sheave, which has since been widely used by competitors.
