Power3 ratchet blocks provide sailors racing small one-designs with three holding-power options to handle a variety of wind and sea conditions. The patented T2 Ratchamatic is Harken’s newest block to feature the T2 line’s styling and soft-attachment system. This high-strength block weighs only a few ounces thanks to composite fiber-reinforced sideplates, an aluminum sheave, a lightweight soft-attach, and a minimum of moving parts in the ratcheting mechanism. All T2 blocks are lashed or spliced through the load-bearing center of the block, decreasing the loads on the sideplates and acting as a safety backup for the system.
Soft Attachment: Lashing allows ratchet adjustment close to the deck. Lashing or splicing provides a variety of options for securing the block at exactly the right height to maintain a fair lead.
Seamless Ratcheting: Pressure on the line engages the ratchet mechanism, which switches seamlessly from free-running to ratchet mode. Unloaded main and jib sheets run out freely during mark roundings, and asymmetrical spinnaker sheets free instantly during jibes.
Directional Markers: T2 Ratchamatic blocks are clearly labeled with high-contrast directional markers for correct reeving and trimming direction.
Applications: Use for mainsheet and spinnaker systems on beachcats, dinghies, and sportboats.
Included Line: A length of Spectra line with a polyester cover is included.
Holding Power: 2x grip: big breeze/steady: 20:1 holding power.
