- Questions

What's the difference between cam cleats and rope clutches?

Cam cleats suit light loads and quick adjustments. Rope clutches handle higher loads, work with larger ropes, and allow controlled release under tension.

How do I choose the right jammer size for my ropes?

Match jammer specifications to your rope diameter. Undersized jammers won't grip properly, while oversized units can damage line fibres or fail to hold.

Can rope jammers damage my sailing lines?

Quality jammers are designed to grip without cutting fibres. Ensure correct sizing, maintain clean cams, and avoid holding lines under excessive load.

What maintenance do rope clutches need in Brisbane sailing conditions?

Rinse with fresh water after sailing, inspect cams for wear and debris quarterly, lubricate pivot points annually, and replace worn cams promptly.
