I'm not sure if an '86 TheMightyHobie18 translates, but here's how I do it with my Aussie halyard ring:
1. The hook on the top of my mast is on the right side. When I attach the ring to the main, I make sure the halyard attachment point on the ring (which is at the 10 o'clock position) is on the left.
2. Next, I raise the main all the way up until the ring is above the hook. I then have my crew turn the mast rotator so that the hook goes toward the ring (port side of the boat if you're facing forward), and then I ease the halyard to drop the ring on the hook.
3. To lower the main, I do the opposite. I pull on the halyard to get the ring off the hook, my crew rotates the mast away from the ring (starboard if facing front), and then I ease the halyard. Since I bought the Aussie ring a year ago, I've never had to go beyond two tries to drop the main.
Hope this helps!
