Designed with the Volvo 70’s and the Cup sailboat boats sailing teams, the low friction KBTi blocks for boats are 60 to 70% lighter than any other existing blocks on the market. Improvements in high modulus boat ropes now allows to use a smaller sheave diameter. We have reduced the size of our blocks to marine suit the new high tech ropes and minimize weight and size while maintaining a very low friction coefficient : 2 patents pending.

Lashed through the center, the KBTi block provides the same safety features in case for boats of over-loading, as the standard K-Blocks.

2 ranges are available, the first is in titanium and is the lightest, but
titanium is not allowed in all classes, so we also produce the KBs
range in stainless steel.
The cheeks are in carbon fibers and the bearing in ceramic or high
strength alloy.
