The Carbo Ratchamatic 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.

Controlled Hold and Release
The magic of ratchet blocks is they allow you to hold loads with little effort and ease loaded sheets with good control. The effect is analogous to a winch without a winch handle. You don't have any mechanical advantage while you're pulling in the line, but the surface of the sheave acts like a winch drum to provide resistance in one direction. The resistance takes the brunt of the load so you can hold or play the sheet with ease.

Sheave Design
Every brand of ratchet block has a signature shape for its sheave. When designing a sheave, there is a tradeoff between holding power, line chafe, and control. In heavy air a sheave with too much holding power will cause the sheet to suddenly slip and jerk through your hands. In light wind and low loads, the line gets stuck in the sheave. Also, sheaves with sharp edges are overly aggressive and destroy line quickly. Weve tested many different designs, like sheaves with more facets or more holding power, but Harken has kept nearly the same sheave design for years. Sailors keep telling us its greatnot only does the shape treat lines well, it offers the perfect mix of holding power and easing ability.

Line Diameter
The diameter and nature of your line has an impact on the effectiveness of your ratchet blocks. Be sure to use line sized to match the block. Line that is too large or two small wont hold well due to a lack of contact with the facets. Hard, smooth lines don't offer the holding power of soft lines.
