Low-friction Carbo Air blocks are lightweight, strong, reliable—and affordable. Companions to our popular Harken Big Boat blocks, these small, compact blocks have very high working loads for safe, easy trimming. Lightweight nylon resin sideplates replace stainless steel straps found in Classic blocks. Densely packed glass fibers reinforce resin for strength.

Carbo Ratchets allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing. On/off switch operates from both sides. Standard grip: medium/light air; 10:1 holding power

Power3 ratchet blocks provide sailors that race small one-designs with three holding-power options to handle a variety of wind and sea conditions. More choices allow sailors to fine-tune their set-ups in tandem with the purchase that provides the ideal level of power, responsiveness and grip. On/off switch operates from both sides.

1.5x grip: breeze–on/puffs; 15:1 holding power

2x grip: big breeze/steady: 20:1 holding power
