Harken's downhaul/halyard sheave makes raising the sail and/or adjusting the downhaul with Harken ball bearing sheaves much easier. This is a direct replacement for the sheaves that came with early Hobie 17s.

Can be used to replace old sheaves on old the hobie 16 jib traveler car that has a cleat and track stopper.  Just drill out the old one and install this sheave with a 1/4 x 5/8" clevis pin and a split ring.
