Locking the Hobie 17/18/20/21 Halyard:
It is best to simulate the halyard locking with the mast down so you clearly understand the system.
Be sure that the knot tied to the ring is very low profile. A long bowline knot will hit the mast head before the ring gets to the hook.
If the ring has a small loop at the top... The line should be passed through the loop and a small knot tied. The knot (when ring and shackle are affixed to the sail) should be facing the mast. This tilts the ring closer to the mast.
Then (before attaching halyard shackle to the sail) spin the halyard 3 or 4 times clockwise (looking down on the shackle). This "pre-loads" the halyard line and causes the ring to swing back towards the hook. Keep the boat into the wind and hoist. Should lock easily.
