Coulda called this thread the HALYARD BLUES.
Long before I bought an ACAT I saw guys turning them over when the Masthook didn't catch the Main.
I'm frustrated. I have tried Rotating left, Rotating Right, all to no avail.
It's complicated by the fact that when you rotate the mast at the last minute to move the masthook away from the ring, the boltrope binds in the track so you can't push it up that last 3 inches up the slot anymore.
My hook was taped into placed to help it stand vertical, that seemed right but if you pushed the hook back on your 1st attempt, there was nothing to push it forward again without dropping the main and resetting the hook position manually and trying again.
I added a foam stabilizer that fits behind the ring, slotted down on sail to keep the ring pushed forward, it now keeps it from pushing backwards, but now it just pushes the ring to the side. Still fiddling with this, It is closer than it was.
I'm no engineer but there has GOT TO BE A BETTER DESIGN.
(Where the heck is Jake when I need him???)
Has anybody found a solution for this? It's hard and embarassing to keep turning the boat over to get the day started . . . .

G'day Cary on my "A" push up main there is a small rubber block that you squeeze in when you put the top catch shackle on (Whatever thats called). You have to put the rubber in just the right spot. There was an earlier "A" thread that showed a photo of it but I cant find the thread. I'll try to drag my main out today and take a photo. Can you post a photo of your current arrangement?
regards

Here's photo's of my setup, I purchased the hook and block from AHPC and converted my A class from halyard to pushup sail its heaps easier rigging the boat

To hook properly, apply Marine Goop to your shackle below the ring. You don't need much, do it on the ground, maybe with a little paper masking tape, and let it start to harden. Mash it back in place gently if it drips.
Once it doesn't drip- say 5 minutes, put the sail up, possibly turning the boat over. When the Goop is pretty hard, after sailing, it will work for months until it shrinks a bit-
Then just apply a little more Goop.
Up or Down- everything works now.


This is instead of the stupid rubber sponge that always moves and falls out.
