Ronstan 55mm Single Auto/Manual Clockwise
Cheek Ratchet Block with Shackle Head
Now you can enjoy the flexibility of setting
up your ratchet blocks to suit yourself.
In the auto mode of the ratchet mechanism
engages when load is applied, but switches off when it's released. This
lets the sheet run out smoothly and freely-great for rapid easing of the
sheet and for gybing asymmetric spinnakers.
In manual mode, the ratchet mechanism can be
switched on or off as required. This is the preferred mainsheet set-up
for may top sailors.
Try the block in both modes and see which
you prefer - you really can't go wrong.
