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, 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. Pressure on the line engages the ratchet mechanism, which switches seamlessly from free-running to ratchet mode.
Construction
• Composite sideplates: Fiber-reinforced sideplates contribute to the block's lightweight high-strength design.
• Aluminum sheave: Hardcoat-anodized aluminum sheave ensures durability and smooth operation.
• Soft-attach system: Lightweight soft-attach integration and minimal moving parts in the ratcheting mechanism reduce overall weight.
• Center load path: Lashing or splicing through the load-bearing center decreases loads on sideplates and acts as a safety backup.
Performance
• Ratcheting action: Pressure on the line engages the ratchet mechanism, switching seamlessly from free-running to ratchet mode.
• Free running: Unloaded main and jib sheets run out freely during mark roundings, and asymmetrical spinnaker sheets free instantly during jibes.
• Directional markers: High-contrast directional markers clearly indicate correct reeving and trimming direction.
