F18 full Mainshit system 10:1 Harken

This system offers 10:1 purchase power! Light weight, low profile and very strong, these Carbo AirBlocks® have enormous working range, with a higher working load than standard blocks, even though they are lighter in weight. The base block has an on-off ratchet and will roll freely in both directions when disengaged, such as in light air. Engage the ratchet in heavy air when you need the mechanical advantage of the ratchet. The 57mm ratchet sheave offers 10:1 holding power, making it easier to handhold in heavy air.

Sold with:

- Top and bottom harken sheaves

- 8 mm tappered rope from Lancelin Diminution

- Wichard carabiner to lock and unlock really easily o the boom
