Please sir, can you tell me where the (thread) discussion on watertight cockpit hatches is?

I think Brent was about to put his batteries under the cockpit. (HOWZ IT GOING?) I'm seriously leaning that way myself but I wanted to research further those square, flush, powercoated alumi8num hatches that were mentioned by Tim, I believe, that were said to be waterproof. It was the thread that Tim gave us a list of Bomar hatch sizes, and discussed a plastic access hatch he got from W. Marine that leaked.

I'd really appreciate knowing which ravelly hole in the threads to look into, thanks!
