Harken Carbo Ratchets allow sailors to hand-hold lines under load and offer balance between holding power and controlled easing.
Harken Carbo Facts and Features:
For the ultimate system mount a switchable ratchet in the cockpit and a boom-mounted Ratchamatic® directly above to allow double holding power in heavy air and to ensure the mainsheet runs freely in light air.

A becket is the starting point for the line in a purchase system, but it is also extremely useful for holding blocks up and off the deck with the addition of a short length of shock cord (bungee elastic) attached from the becket to e.g. the lower rail/guard wire.
