Hi Mikes and welcome to the forum. What an inopportune time to make such an unfortunate discovery! Thanks for the heads-up.
My adventure has the retrofit newer hatches, and I'm happy to report that the screws are fully contained. I'm a little puzzled that you've been waiting so long for the newer hatches -- didn't realize they were out of stock. You might give Hobie a call or check with another dealer.
If you'll be putting anything inside the hull in the meantime, you'll probably want to temporarily blunt the existing screws (but you may need to reuse them on the new hatches). or secure the contents away from the hatches.
Hope everything is clear sailing from here on out!
