Lagoon delamination or osmosis does anyone had experience?

This thread is to ask if anyone had experience of delamination or osmosis in lagoon catamarans, and also which are the common issues of these boats

thanks for sharing your experience

Have 6 small blisters behind a seat cushion that was wet for 4 months, my fault.
Otherwise a great boat.
It has a hard top gelcoat in white which hardly comes off at all when polishing.

Re: Lagoon delamination or osmosis does anyone had experience?

A 440 i looked at in the USA was fairly heavy in the stern, when i inspected it on the slip there were some blisters in the gel-coat around the sugar-scoops it was normal gelcoat blistering.
All up i checked out 6 Lagoons on various slips and haven't seen any thing untoward.

Cheers Frank

Re: Lagoon delamination or osmosis does anyone had experience?

Friends had an old Lagoon 47' for 20+ years - they skippered it when it was in the Moorings & then bought it when it came out of charter. No blister problems ... until they hauled this year, & suddenly the bottom was covered in blisters. Don't know what (if anything) they'd done as blister prevention before. Of course, this means nothing about how current Lagoons will last...

We wre in the process of purchasing a 2008 Lagoon 420 and, contrary to my earlier understanding, I'm told that instead of being solid glass the hulls are cored below the waterline. Can anyone confirm? Also, any reports of blisters with these boats?

If you look in the bilges you'll be able to see where the coring stops. The coring does go below the waterline but usually stops 18" to 24" before if gets to the keel and they stop the core around and through hull fittings. Where you run into water problems in the core is when a through hull fitting is installed after the boat leaves the factory and they don't do it properly.
From my experience, blistering in very rare on Lagoons.

Re: Lagoon delamination or osmosis does anyone had experience?

There is a Lagoon in Malta at the moment being treated for delamination/osmosis. They have (so I'm told) sandblasted to remove the gelcoat. Just how extensive I'm not sure but look forward to receiving more info. Just how they intend to return this boat to factory finish is the big question.

Curious to know the make and year of the Lagoon you are referring to.
Thanks

Re: Lagoon delamination or osmosis does anyone had experience?

Last month we have taken the boat out after two years in the water for new antifouling.
On the inside of the port bow there were signs of delamination.
The manager of the boatyard, said the he have seen several instances of such delamination on Lagoon of about three years of age.

Re: Lagoon delamination or osmosis does anyone had experience?

Seems strange a yard in Malta has seen several? How many 3 year old Lagoons in particular slip in Malta compared to the rest of the world?

Curious....
