Leaking Cabin Roof

[peteandfranscott]

My cabin roof leaks every time it rains - but only on the starboard side!
There seems to be a little assymetry in the exact position of the tracking grooves on the two sides. Does anyone else have this problem? If so - have you managed to solve it?!

Hello Pete

Welcome to the forum,:) I may be wrong but I think this is one of your first posts, which is probably why it is in a strange place (in the Forum Management section). Maybe Simon (Head) will be able to move this thread to a more appropriate place. Not to worry, I am sure that we would rather have posts in strange places rather than no posts at all, it is good to hear from you.

I had a leaking cabin roof on Mary Ann. The leak was through the holes for the screws attaching the channel for the spray hood.
Remedy was simple. I removed the plastic channel cleaned away the old silicon sealant and reassembled on a new (generous) bed of silicon sealant (mastic).

However, there are many other through screws in the cabin roof, they will all have been sealed initially but any one could leak. Simply remove and refit with plenty of silicon (mastic).

Best of luck

Dear Pete and Dennis
We have had lots of problems with leaks.
First of all our forward hatch leaked but has been refitted by a local yard and is now water proof.
We then discovered that the cabin hatch also leaked to such an extent that we have had to keep all the mattresses out of the boat and 4 life jackets inflated! We are planning to take her to a yard nearby in Milford Haven this winter to see if we can find the leak and repair it. When we do I will let you know. I have the suspicion from talking to Bob that this is not uncommon and they are looking at the design of the hatch cover.

Are you sure that's not "Punt and Dennis"?

If your problem was not so serious, your comments
would sound like one of their scripts.

No practical input I'm afraid.

Hello John

Welcome to the forum.

Sorry to hear about your leaks. I assume yours is a Honnor Marine boat.

Bob told me when I bought Mary Ann that he had changed the design of the hatch, but I do not know when he did this. Certainly on "Mary Ann" (hull number 100) the hatch does not leak. The only time I have had water "down the hatch" is when I have inadvertently left it open when sailing (in the rain), and the sail has dumped a load usually when tacking or sail handling (raising sail or reefing etc.).

How is your boat moored? Mine is on a swinging mooring and is therefore always head to the wind and I usually keep the spray hood up which also helps. However, even when sailing (with sprayhood lowered) in heavy rain I have not experienced leakage via the hatch.

There must be a simple reason (and cure) to your problem.

Cheers

Dennis

I also suffer from leaks at the main hatch,so much so that the boat came with a detachable nylon cover!
I spent some time last winter sealing the blessed thing but without total success.
I am just about to strip it down again to have another go at it.part of my problem would seem to be that the acrylic sliding part is slightly bowed.
I bought some flocked rubber from Seals+Direct.
Its amazing how much water can come in the smallest aperture.
interested to hear how others get on.

For what it's worth, Moonstruck used to leak as well through the main hatch. I then realised that I was storing too much in the bow, under the mattresses, including the dinghy. So Moonstruck was lying bow down in the water.

The result was rain falling along the hatch channels towards the bow, and then finding its way below.

So all I did was move the dinghy to the rear of one of the quarter berths, and when sleeping alone onboad also using a quarter berth. The boat lay as she was designed to, no more leaking.

Cheers,

David

lets hope its not raining when the boat is pitching.

Leaking Cabin Roof

My cabin roof also leaks when it rains. It leaks from two places:-

1. The fixed skylight in front of the garage.

2. The sliding hatch.

I have carried out and tested a simple modification and can now report that the hatch no longer leaks.

Please see the Articles section for my solution.

Is this a problem only affecting newer boats (what Hull No is yours, Oak?)?

I have had mine 7 years and never had any problems with leaking hatches (last time I used it it was monsoon weather!!!). I know earlier boats had a lifting hatch arrangement that leaked and was replaced with a "mod2" (up to Hull 28?) arrangement which eventually led to what we should have now, although this may have changed with the HM boats. My hatch slides with little latteral movement

Anyone have any ideas. It seems to me that this has changed in design. We could do with cataloguing the development of the CC 19. I know from looking at very early boats that the deck mould is different, and the transom is quite thin.

As a matter of interest I would never stand on the hatch for fear of cracking it (I am 16 stone, however!!!!).
