The patented T2 Ratchamatic is Harken’s newest block featuring the T2 line’s styling and soft-attachment system. This high-strength block weighs only a few ounces due to composite fiber-reinforced sideplates, a hardcoat-anodized 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. Lashing allows ratchet adjustment close to the deck, while lashing or splicing provides a variety of options for securing the block at exactly the right height to maintain a fair lead.
Lightweight Design: The weight of this high-strength block is only a few ounces, thanks to composite fiber-reinforced sideplates, hardcoat-anodized aluminum sheave, a lightweight soft-attach, and a minimum of moving parts in the ratcheting mechanism.
Soft Attachment: 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.
Adjustable Height: Lashing allows ratchet adjustment close to the deck, while lashing or splicing provides a variety of options for securing the block at exactly the right height to maintain a fair lead.
Ratcheting Mechanism: Pressure on the line engages the ratchet mechanism, which switches seamlessly from free-running to ratchet mode.
Performance: 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.
