Designed with the Volvo 70’s and the Cup boats sailing teams, the low friction KBTi blocks are 60 to 70% lighter than any other existing blocks on the market. Improvements in high modulus ropes now allows to use a smaller sheave diameter. We have reduced the size of our blocks to 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 of over-loading, as the standard K-Blocks.

The Carbo Ratchmatic® is a load-sensing ratchet block that rolls freely in both directions under low loads, and automatically engages the ratchet as loads increase. Shifting between ratchet and light air modes is seamless. Unloaded main and jib sheets run out freely during mark roundings and asymmetrical spinnakers free instantly during jibes.
Ratchet engagement may be adjusted to a higher or lower load according to strength and sailing style. The Ratchamatic® cheek block mounts on either port or starboard. Holding power of 57 mm is as high as 10:1. The 75 mm up to 15:1.
For the ultimate system, mount a Ratchamatic® on the boom above a cockpit-mounted switchable ratchet to allow the mainsheet to run freely in light air, and ensure double holding power in heavy air.
Use the 2634 with a 402 or 403 swivel arm for a versatile two speed mainsheet system.
