Just a heads up for any other hatch-builders out there, there is a super deal on Southco Latches on ebay right now. Just go to ebay and search Southco or see if this link works. The seller is Bontrager RV Surplus.

They came in at $10 per latch so I bought enough for a few boats, sounds like they have a big crate of them in both black and white. Much better than any of the metal pull-style latches available for a dory or even dry-box in a driftboat. This is the best deal that I've seen on them.

Happy hatch building!
