Hull Windows
Has anyone had this happen or seen this rubber trim come unsealed?

Re: Hull Windows
Not as extreme as that. Mine just had slight gaps in them where sealant came away from a small portion of window. May have happened during lift out if slings were not in correct position, causing hull to flex ie extra load on windows.
This sealant often "dries" out and needs to be replaced. Just cut out with a box cutter, tape around window & hull, then re-seal.

Re: Hull Windows
Hmmm mine was doing it before the haul out. (First haul out) No sign what so ever on the inside of the window caulking having any issue.

Re: Hull Windows
Sounds like a warranty issue - get your dealer onto it

Re: Hull Windows
The dealer said it isn't covered under warranty.

Re: Hull Windows
Is the window acrylic? Does it rely on the caulking for adhesion to the hull and has that adhesion failed on the underside or is there a mechanical joint? If it relies on the caulk for adhesion and it is acrylic, it's probably not as simple as re-caulking from the outside as there are only a few products that will stick it to the hull. Ask me how I know!

Re: Hull Windows
I have the same problem Mike on a 2016 450S. Not sure what to do, My marina neighbour had a window fall out of his 620 one night but I'm not sure if he had this problem prior. Also a 2016 boat.

I have kept a careful watch on the inside and there is just no sign of a problem. I am rather disappointed in lagoon saying not a warranty issue. I noticed it at about 10 months but now 14 months and its really getting bad. They did suggest that i remove caulk and re-caulk with this. which i can buy in west marine Phuket. Another project!

Re: Hull Windows
Hi Mike, regarding the product you use to recork. It needs to be one that has high expansion rate. The acrylic and gel coat will expand at different rates, if the product you use doesn't have 50% expansion ability the seal often breaks.
I'm not familiar with the product in the photo. I know both Dow corning and Sikaflex do make a specific product for that application.

Re: Hull Windows
I really can't believe Lagoons attitude to this. Are you sure your dealer has discussed this with Lagoon or are they just taking the easy path & saying 'not a warranty issue!'
It is issues like this which send potential buyers to other brands - Lagoon need acknowledge their failing here & fix these windows.
Good luck.

Re: Hull Windows
GE Silpruf is extremely flexible. It’s now used to reseal Island Packet chainplate covers where I believe 5200 was originally used. The 5200 was not very flexible and the seal would break due to that.
This is a copy of the data sheet for Silpruf, I believe it has a 50% flex

Thanks, Dale a problem sometimes being in Thailand. Import products are hard to come by at times.

Re: Hull Windows
When you re-bed it, do not push too hard and expel too much sealant. It needs about 5mm to be able to flex with differential expansion. A thin layer is more likely to fail.
Try to put 4 spacers in the corners.

Re: Hull Windows
The other alternative (if you take the window completely off) is 3m tape and corking the perimeter.
