One of the two large deck hatches has developed a small leak on my 10 Meter.
I have never re-bedded or done anything to them them in the 11 years I have owned this boat.
As she is now 30 years old, it's probably time. Eventually they will be replaced as cosmetically they don't look great and the acrylic is showing it's age, but for now I really need some giudance as I know nothing about these hatches.
This is a simple piece of flat acrylic on a hinge with 4 clamps.
The only thing visible on top is the rubber gasket.
Thanks,
RWS

I have on occasion (for a simple quick fix) used black silicone. Put a dab in the leaking area, cover it with saran wrap, then close the hatch (worked on auto T Tops back in the day) When it dries the saran wrap pulls right off and you have a perfect gasket. This is not rebedding as you asked, but a simple stop leak till you replace the hatch.

What bob said. A bad gasket is more likely that bad bedding. Look for gaps in the gasket.

Need to figure out what exactly is leaking which is not always easy. I have 22yr old bomar hatches. I've had one where the bedding of the lexan within the frame was leaking. I cut out the lexan panel with a razer blade (which can then be replace if necessary). Rebedded panel in frame using GE Ultraflex structureal glazing compound. On another hatch I was getting a drip between the unit and the trim ring inside. Figured this was the bedding so I cut out the old stuff with a razer knife and recaulked with BoatLife Lifecaulk. The other option for leaking would be a bad gasket as mentioned above. You can order gasket material and replace as needed.

I had one leaking 3 years ago and it was clearly the bedding, you could see no water coming in at the hatch, it was running over the headliner and coming down all the way at the front by the head of the berth. At first a drip, eventually like running water LOL. My marina tried to tell me it must be the gaskets but that wasn't the case, as like I said in that case I would have seen water coming in at the hatch itself. I pulled it and re-bedded it, and no leaks since then.

First step is determining what is leaking. Smartly you came and asked for experience as what is usual. The bad news is that given the age, it could be either by the typical gasket leak, or very well could be the bedding as well (around the plexiglass, or around the frame where it is bedded to the boat. You have two options. One is to get scientific about the thing and find a way to determine what exactly is leaking. The other is the pull the whole thing apart, surgically clean the mounting areas and re-bed it. That's what I had to do to mine and it WAS the sealant, not the gasket that turned out to be leaking. Like you, I did not have time to paint the frame when I did it, so some day I'll get to do it all over again. Welcome to boating!

Replace the O rings on the dogs (locking handles).

Finding out where the leak is is the hard part. Unless you want to tear it all down and restore the whole assembly...
Take a bottle ofbaby powder and dust all the whole area with a coat and lightly spray down the hatch. You should see where the leak is by following the water marks in the powder.
Many times the actual leak is a ways away from where the dripping is seen/felt.
