Ratchet blocks are hand and crew savers. The eight-sided sheave grips loaded
sheets with up to 15: 1 holding power yet allows a line to be eased instantly with
control. They allow the crew to hand hold main, jib and spinnaker sheets with
only a fraction of the effort that a regular block requires. An on/off switch allows
the ratchet to be turned off in light air to trim and ease lines more easily.
The 2608, 2609 and 2614 have on/off switches; other 40 mm ratchet blocks are
always in ratchet mode.
57 mm (10:1 Holding Power), 75 mm (15:1 Holding Power)
All 57 and 75 mm ratchet blocks have on/off switches.
