795 Starboard Window Leak

[mhorvath1218]

My starboard side window in my 2017 leaks when it rains. Water collects on the interior side between the glass and fiberglass at the bend, right above the sink. There is no clear entry point and no water dripping down the interior side of the glass, but a significant amount of water collects at the bend then drips onto the countertop behind the sink. Has anyone else experienced this and have a fix? The only thing I can think of is the sealant at the bottom of the exterior of the window may be letting water through, but it appears to be in fairly good condition still with no obvious separations. I was going to try some new caulk sealant in this spot, but wanted to see if anyone else has identified and fixed this issue first.

As an initial step, you might try a bottle of Captain Tolly’s , it is a super thin sealant that capillaries into tiny leaks and sets when it meets a damp spot, can stop some leaks without the unsightly spread of silicone sealant. Get ready with some meths to clear spills though as it’s difficult to remove drips once set, masking tape helps.
It won’t replace a full pull out of the port light, and re seal, but is much easier and just might stop it for a few years.

Thank you! Never heard of that stuff, but it sounds like exactly what I need. Just ordered a bottle!

I have exactely the same issue with my brand new MF695 S2. The boat was sold to me just three weeks ago and we have had quiet heavy rain falls during the last weeks here in Switzerland at Lake Constance. 

The incoming water follows the way described by you. I contacted the shipyard/seller and they contacted Jeanneau. Reply of them was that this issue is known by them and the problem is under the plastic shield which is sticked over the A column right of the windscreen. 

As i got this message I taped the plastic shield/cover with a water resistant adhesive tape of high quality. Since this, no water was coming in anymore. 

As I have the Jeanneau guarantee the boat is back in he shipyard for repair. Hope they can make proper a sealing fast that I get back the boat soon. 


Regards

Hello! Have you solved your starboard window leak issues?

I had similar situation last summer a being moored, but it wasn't that bad. But this week I had a massive leak over the past few rainy days - about 200-300ml per day. Water is collecting at the same place as you mentioned. I put a plastic tape on the A-pillar cover where it touches the windscreen to check if that stops the leak, but it had no effect. I have found no other source of leak either.
