The Ronstan 40mm Orbit auto-ratchet block is a great, cost effective option for junior classes and smaller skiffs. 

The automatic ratchet engagement helps with smooth gybes and the dyneema link is easy to install and compatible with a range of connection points. The 40mm Orbit has a 14:1 holding power and suits ropes up to 9mm in diameter.

SkiffRopes recommends the 40mm Orbit auto-ratchet for:

• 13ft Skiffs
• 29ers
• Flying 11s

Note: Senior skiff classes should use a 50mm or larger ratchet block.
