Default Truly waterproof deck plates/ inspection hatches

I am installing several new round (possibly one rectangular) deck hatches (say 6 to 12 Inches diameter) in a new glass covered plywood deck in my 18 foot Privateer center console, two of them over the gas tank fittings. I want them to be absolutely waterproof if possible. My experience with Beckson and Bomar hatches from West Marine, both snap in and screw in, round and rectangular, is that they are not reliably waterproof. I have heard that the deck plates from Armstrong are the best and truly waterproof. I have never seen an Armstrong hatch and they are not carried in any local store to enable me to take a look.

Any thoughts or experiences with this subject would be greatly appreciated.

Thanks

Seal the hatch to the deck with a little 4200 and then seal the oring on the screw/snap in section with some silicone so it can be removed with a little effort. I had one on an engine bracket that leaked and this solved it.

I replaced both bildge access hatches on my World Cat with the Armstrong hatches. They are without a doubt the best I could find, They have a mechanism that allows you to tighten the hatch down. It may present a slight tripping hazard if you install them on your deck. You can order them directly off of their website. They were very informative and helpful when I purchased mine.

I absolutely agree with the information offered. I also replace the hatches in my motor wells on my Sea Cat with them. They are much easier to remove than the screw outs or the pry outs with one hand, as space is restricted in my case due to a ladder.

I would not want to use them on my deck, unfortunately, as the very thing that makes them work so well, also makes them a tripping hazard. For any other location, where access is needed I can highly recommend them.

They aren't pretty though.

not sure of the hatches, but the plates are way superior than any other I've seen, there O-rings are the not cheap flimsy ones you see on the other brands. I've never had a tripping issue cause mine was under the leaning post, good luck.

We found that inspection ports need maintenance to stay watertight. Pull the o ring out clean it and lube it with silicone then also clean the groove it fits in and the mating surface in the deck portion.

Ours are bronze and work very well.

Sorry, not familiar with the Armstrong design

Default There are no round deck hatches leak free

The only way to stop a round deck hatch from leaking is to seal it completely. A PITA when you want to open them. But, why would you want to open a sealed hatch? You know it no longer leaks.

Deck hatches leak in all boats. just put a camera recording the underside of the hatch and then flood the deck.

Sadly the ones in the motor well are the leakiest.

I'm not aware of any recreational level removable hatches that are, and stay, waterproof. Unless you seal them yourself, which kinda defeats having easy access anyway. Bilge pumps that work, FTW.

The best hatches I have used are the Armstrong. They work incredibly well.

Armstrong all the way. I have 4 of them and won't use any other type again. Maybe for less critical applications, but nothing but Armstrong for sealing up bilge access. They are very strong and don't flex when you step on them.

I'll never use another product. I think they look cool too. I hate the look of the cheesy little screw in plastic pie plates.
