63 mile upwind passage yesterday, gusting to 20kts+. Lots of spray ...

This morning found significant puddle of water in focsle. Not salty however ... ??

Leak seemed to be coming from rubber surround of the perspex. What can be done to sort this 9 year old hatch?

PS will look for other water sources but that looked to be the culprit.
 
For a quick fix you could try Captain Tollys creeping crack cure but for a permanent solution you will need to remove the Perspex and rebed with something like CT1.

Thanks for the tip. My hatches (Maxwell) have leaked from new. I blamed myself for the way I installed them but when I had removed one I measured it diagonally and found it wasn't quite square so what hope have I got?

I thought of getting hatch covers but found they are expensive and only last 2/3 years. My idea was to stop leaks and to prevent deterioration of the perspex from crazing of the perspex.

I made up fiberglass hatch covers and now the leaks have stopped. I think the f/g covers would be useful in tropical climates in helping keep the yacht cool.

I had a leak in my old (Lewmar) forepeak hatch - the rubberised sealing had aged and become unbonded from the perspex. The fix is straightforward but quite time-consuming to do well and, naturally, leaves a big hole in the coachroof while it is being done. However, I stemmed the leak for almost an entire season with carefully applied PVC tape - cheap, easy, effective and surprisingly long-lasting (although I usually try and avoid conditions that produce slamming and green water over the bows).
 
obviously depends where it leaks, had two leaking sliding hatches recently
glass had separated from the rubber seals that interfaced with the allu surround
v carefully cut the rubber, stanley and scalpels and extracted the glass
cleaned it all up, set up some spacers on the frame so the top of the glass would be level with the frame
taped off the top of the frame, got the black sikaflex out
several rolls of blue paper, a fair amount of solvent and the mess was cleaned up
that was 2 years ago, not leaked yet

and, yes pvc tape keeps the leaks to a minimum for a while, you can get this in wider sections
 
Over size Canvas hatch cover made up from chap advertising on Ebay.
Studs at each corner.
No more wet bed, all for around £40.00 and half hours work.
Removed and stowed when no chance of rain or spray, normally stays put overwinter.
Boat used and slept on all year round.

Not great for letting light in and not very effective if there’s waves washing over the deck.

9 years is not long and the hatch shouldn't be leaking. However, I don't suppose Lewmar are going to be very interested. The only leak I have had in my 20-yr old hatches is from the locking handles, one or two of which occasionally come loose, allowing rain to get past the seal, curable by tightening the screws.

On the other hand, a puddle of water that isn't salty doesn't sound like spray getting in.
