The patented T2 Ratchamatic is Harkens newest block to feature the T2 line styling and soft-attachment system.

The weight of this high-strength block is only a few ounces. This is thanks to composite fiber-reinforced sideplates, 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. 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.

Unloaded main and jib sheets run out freely during mark roundings, and asymmetrical spinnaker sheets free instantly during jibes.

T2 Ratchamatic blocks are clearly labeled with high-contrast directional markers for correct reeving and trimming direction.

Use for mainsheet and spinnaker systems on beachcats, dinghies, and sportboats.

A length of Spectra® line with a polyester cover is included.

Poor sole design could result in injury to heel.
Size: 11, Color: Grill/Mint Wave
These would be so much better if the sole did not expose the heel to possible punctures. There is an actual cutout of the sole where only the spongy part of the shoe is exposed to the heel. Anything sharp will go right through.

Excelente producto
Size: 8, Color: Black/White
Sandalias muy cómodas para caminar, recomendadas para utilizar en viajes largos y clima cálido. Sugiero comprar una talla adicional, sin embargo siguen siendo muy cómodas.
