Ronstan Orbit 55 Auto/Manual Ratchet Block

" through what appears to be clever engineering, only the loaded portion of the "floating" aluminum sheave comes in contact with the ball-bearing arrangement. This makes for smooth trimming and blazingly fast sheet runs at the weather mark and late dips" From Dave Reed's Sailing World Review

. Read the Sailing World Review of this Block

These are easy to use as the ratchet function engages automatically when there is enough breeze. The ratchet auto disengages in lighter air or when easing for the run. Unlike competitors this can also be switched on and off.

Now these auto/manual ratchet blocks come with a stainless steel swivel shackle for ultimate durability.
