Re: Lagoon delamination or osmosis does anyone had experience?

That's cool, Minaret their is no debate i did cut 3 holes to fit the sink wastes but they were above waterline and were Balsa'd so no real help, i'm cleaning the boat for winter layup and think i may have those somewhere BUT that won't answer your question.

Now i've just replaced our 'Sea-Recovery' heap of crap water maker with one i built which Tellie would be happy to use i'm sure. The old 'Energy Transfer Device' i intend on mounting in the 'Port Engine Room' and for that i'll be hole-sawing a 1" intake and fit a sea-cock to supply the valve.

I go on the hard around the 21'st and will cut the hole about 500mm from the 'Cofferdam' that Volvo supply to mount the engines on, i won't be cutting it where the hull is thickened to glass in the cofferdam or bulkhead as i don't want to compromise the taping, it will be in a clear space.

One thing that may be detrimental in some ways in some peoples eyes LAGOONS are not known for being lightweight, i've built Western Red Cedar lightweight cats and Schionning Cats in Kleggy and i gotta say these boats are heavily built.

So around 21st/22nd November the pic's will be posted , of that you can be assured.

Cheers Frank

I have a report on hull core samples taken from a 440 completed by a university testing center if you want.

That would indeed be very good, i have only got a photo of where the hull section has been cutout and re-used for the cover plate where the Swing Thruster is mounted and it was around 12mm thick at the thinnest point.

These boats have very solid hulls, we bumped a floating steel wayward anchor bouy, about 500gallon size 2 weeks ago just above our waterline to no detriment.

Lightly built these boat's are not, please post the report if it goes to thickness of the underbody.

Cheers

Remedy is to re-lay new glass into the recess which is what the yard are presently doing.
This area as boat poker shows has the pre moulded VOLVO cofferdam glassed in place behind it.

Frank,

I notice Col's posts. Cheers

Re: Lagoon delamination or osmosis does anyone had experience?

Exactly John, this is a none event blown out of proportion by an angry person with a chip on his shoulder who cruises the Lagoon Forum probably because it's the only cruising he see's these days.

Getting colder here the season's gone.

Cheers Frank.

Re: Lagoon delamination or osmosis does anyone had experience?

Went through something similar in 2011 after we'd bought a Lagoon 380 in 2010. Ancasta, in the UK, did the (private) sale and purchase for both parties. We knew there were problems with "voids" after our survey. But after Ancasta had repaired the ones we'd found they wouldn't search for any more assuring us that - if we found any more later - "that's what warranties are for".
So in 2011 (before the hull warranty period expired) we hauled her out and blasted the hull and lo and behold both hulls were riddled with voids! We filled all them, coated with 3 coats of epoxy and two coats of Copper Coat, all trying to save Lagoon from replacing the gel-coat. Glad we did because they refused to answer our e-mails or inspect the boat and eventually refused to pay up, saying WE had not had the warranty transferred from the previous owner!!!
We love the Lagoon boat, and folks at Ancasta are great when your buying BUT they will both wriggle out of anything with a policy of 'deny everything'. It took us forever before they eventually wore us down and we settled out of court for less than it cost us. The lessons are obvious.

Re: Lagoon delamination or osmosis does anyone had experience?

Hi all Cruisers,
New information on osmosis L440 build date 2010. Both inner hulls from one end to the other. Hundreds of blisters, photos can't be loaded from my iPad by the look of it, but they will be posted ASAP. Resolution not determined at the moment, Lagoon on notice but almost four weeks and no reply. Time to go public is almost here and numerous Marine Webb Sites will feature the details, it will be on here first.

Re: Lagoon delamination or osmosis does anyone had experience?

Just out of interest Mike 440. How sure are you the blisters are from osmosis?

The boat was hauled out for yearly AF and during preparation the yard discovered the blisters. When pushed with the point of a key they would pop and release water. Large area of discoloured gelcoat around a cluster of blisters indicating significant moisture under that whole area.

Re: Lagoon delamination or osmosis does anyone had experience?

I would be interested to hear how you get on with this problem. I also had a few blisters during the first year. Our AF was put on at the factory. When we hauled the boat I had 2 coating specialist from 2 different companies International and Altex, look at the problem also a couple of shipwrights and all came up with the same opinion that the problem was definitely not Osmosis. It was solvent entrapment. I was told if left it may cause problems. So we had to remove all coatings and start again, a real pain in the A.... but I was glad it was not Osmosis, anyway I feel we have a far more superior lot of coatings on now than from the factory, in fact they did some tests which you could measure the thickness of the original coatings and they were found to be fairly thin.
We did test a few of the blisters and we could not smell the acidic smell from any of the blisters which is a tell tail of the osmosis.
Anyway as I said would be interested to hear how you get on with it.
