Harken 57mm HTE Carbo Ratchamatic
$122.95
The Carbo Ratchamatic® is a load-sensing ratchet block that rolls freely
in both directions under low loads and automatically engages the
ratchet as loads increase. Shifting between ratchet and light-air modes
is seamless.
The spring on the HTE (high-threshold engage)
version of the 57 mm Carbo Ratchamatic blocks was made stiffer to delay
the point where the ratchet engages, allowing the block to run free more
of the time. The ratchet function engages at higher loads to allow the
old kite sheet to run free for crisper gybes.
