Clutches and jammers aren't for every application, but there are many instances where they will out-perform your cam cleats. These types of rope securing devices are particularly useful in situations where you need to accommodate higher loads. Clutches work by keeping the line captive to avoid accidental release using a one-way valve that lets you trim the line in as-needed. However, you cannot ease the clutch until the lever is opened. Jammers are designed for use in situations where you're using the winch for release or in higher load rigging applications where cam cleats don't supply enough strength. Atlantic Rigging Supply is the best place to find sailing clutches and jammers by Ronstan, Spinlock, Lewmar and other top sailing brands.
