Are Lagoon Catamarans Falling Apart?! - Ep 229 - Lady K Sailing

Thanks for sharing. When I was in the market for a new boat, this stuff was coming out. So, I took a hard pass on Lagoon - not because I thought the boat was going to fall apart on me - I rejected the Lagoon because of how they handled it and tried to blame the owners. That was enough to take them out of consideration. I’m astonished that anyone would buy from them if they were reasonably informed about how they handled this.

How is ignoring the issue until it blew up on social media "doing the right thing"? 3 year warranty is a joke, they should have fixed all 450s - no exceptions. Instead of looking for every way out on a case by case basis. You would expect a cat to last 30 plus years, the residual value it compromised. This probably would have still been cheaper for them than the loss in value to owners and loss of confidence and sales to themselves.

Lagoon backtracked after everybody went nuts. They were blaming owners and everyone but themselves but the power of the internet prevailed.

[@johnhayford5946]

As I have reported on a few other Lagoon related channels, I owned a Lagoon 470 way back. It was one of the last ever made, and one year old when i bought it. It had hardly been used, 50 hours on the engine if I recall. It was my first boat, and at the start I loved it, but as time went on and we experienced different sea conditions it started to make and more importantly the wife nervous. The first worrying issues was the noise in anything but millpond conditions, it creaked and groaned horribly. It also slammed but not as I found out as badly as some. Then the cracks started appearing in the gelcoat, mostly where the superstructure joined the hulls. We had this fixed, then next bit of rough seas they all came back. We came across other owners where the salon windows were starting to pop out, and one 500 owner who had small mounds of wood shavings, after crossing the Atlantic where the wood fixtures meet the hull. When more cracks started appearing around the salon windows I called it day and sold it. I just felt at the time it was flexing was excessive. I went on to buy and older Beneteau monohull. It's 20 years old now and still going strong. I do keep a close eye on potential points of failure just in case.

Those mass produced catamarans rarely have proper ring frames and compression posts, which could request 100 + layers of unidirectional glass/carbon and they are more build for marinas and floating around instead of sailing. It helps to consult an expert also when buying a new cat.

Thank you for having dealt with the topic that affects the Lagoon 450 but probably also other "Condomarans"... I have been racing on small cats since the early 70s and I am well aware of the enormous forces that affect the structure of catamarans . I was fortunate enough to know the designers of the first Catanas personally and they were well aware of the problems they might encounter. I've done many miles cruising with those Catanas and I know very well that the feeling of safety they instill with a stiff breeze can push you to overdo the sail area. It is unacceptable that such an obvious defect comes to light only thanks to the WEB. Lagoon will lose many points in the market as a luxury brand, trust is everything! Too bad, some models were very successful...

[@Dlgeis]

BS Beneteau designed, sold, and collected profits on a defective design. They stonewalled the owners until they eventually had so much bad publicity that they had to deal with it. Their fix still leaves owner to do the labor or pay for the labor to be done. Every Lagoon 450 should be recalled and repaired at 100% Beneteaus expense to include $ for every day the boat is out of service. One less sailboat company could make a difference let them sink into another has been company. You either back your product or disappear and good riddance.

[@EdwardTilley]

There are 50+ foot Lagoon problems as well, the owners are just keen to hide it for fear of stigma and lost resale values. If your 60' Lagoon Catamaran is keeping you awake with squeaking and cracking on passage or in heavy mooring waves, you have a bulkhead issue. I've seen them in KZbin videos as well. There is no serious creaking on a properly repaired catamaran.

[@scottwhitfield1456]

Agreed the 52s have numerous issues as well, add a charter base manager informed me. It seems overall production quality issues.

[@patrickradcliffe3837]

4:29 this is incorrect description of what is happening the hulls are not distorting but rather when the rigging is really tight it puts more stress on the transverse bulkheads splaying the hulls apart from each other. Rough seas magnify the issue to the bulkheads fail in compression. 12:33 I would not call it a design defect per se, but rather using incorrect and substandard materials in the construction. They NEVER should have used polyester resin and that cheap plywood in the construction of the bulkheads. Epoxy and heavier weight glass and broader tabbing and they never would have had an issue. Bean counters pared down to much the cost of materials and sacrifice of quality.

[@scottwhitfield1456]

I spent years repairing Lagoon (and other) catamarans in Tahiti and Panama. The brand name says it all: Keep her inside the lagoon, better yet, in the marina to prevent it from falling apart. Poor choice for someone planning on keeping a boat for the long run, it`s best to purchase one fairly new, then sell it to the next cruiser after following Jimmy Cornell`s route around the world.

[@markmccabek9]

I can't say enough how much I appreciate that you were not only thorough in this, especially leaving resources for people to go deeper, but you were very balanced about it, no unwarranted bashing of a company this is doing far more than most would in trying to make things right for their owners. Also making it clear, as many others have not, is that a far as we know, this issue is restricted to one model over several years. I also think it is extremely likely that future Lagoon buyers will greatly benefit as it seems certain that the company is learning some valuable engineering lessons from this that they'll be able to put to use in current and future production!

[@faircompetition1203]

Lagoon only owned up when they had no choice at all and if you have an older one they reserve the right to blame you for their factory defect .

[@tomwolniewicz]

There's a reason why Leopard and other manufacturers use steel cross beams connecting the two hulls. Beneteau/Lagoon opted for wood/fiberglass even for the beams, this being a less expensive construction option! Its not just the bulkheads but the beams that are cracking as well.

[@charlorivas1669]

Very informative

[@andrewstafford6783]

Lagoon do supply a fix but the stainless steel brace kit they offer is flawed - more extensive measures are needed to fully secure the 450's as the stresses simply transfer to other structural areas which will, in time, also fail.

Awesome reflections on the situation! As always, stay safe out there!

[@scottwhitfield1456]

It's not just the 45s that have quality issues. After chartering a 52 with many issues, the charter base manager confided that the 52s specifically have had numerous issues. I love the brand and I hope they resolve the production quality issues by the time I'm ready to buy in a few years. But it appears they have sacrificed quality for profit.

[@pewpewnando]

It is NOT only the 450 that has issues other models also have bulk head issues

[@sentenced2sail]

Dude, i must have spent a year of my life trying to adjust the steering cable tensions on these pieces of crap, the hulls flex so much that if you adjust the tension correctly in port, the pulleys will rip off the bulkheads during the next passage with large swells. The Volvo Penta toy engines they install in them start leaking oil very quickly, the sail-drives are falling apart after 2 years of use. Now they have yanmars installed, but they often get damaged by seawater leaking over them from the crappy engine room hatches and poorly designed ventilation. The fuel system is adequate for north american and EU ports, but there is no provision to deal with contaminated fuel, you got a tiny diaphragm pump trying to suck the fuel through a 10mm hose from 25 ft The salon plexiglass windows are almost impossible to properly seal because of the excessive flexing. The false keels are held into the hull by sikaflex sealant, they tend to fall out randomly. It is a shame that these boats even managed to get the USCG and CE certifications....

@6:12 "We what the boat was intended to do". See that's the main issue I think. Lagoons were never made for bluewater crossings. They may be marketet as such but that's fake. They ain't what they propose to be. They were originally designed by interieur designers so that's where the saying comes from that they build the boat around the curtains. At one point the interieur designers interrupted the boat engineers and said that they can't build the boat like that because they need the space for their idea. From that point on they build the engine compartment in a way so that the rudder is in front of the prop. Like WTF. People need to stop thinking about blue water crossings when they think about Lagoon. All they are good for is hanging around in bays while chartering. But getting from bay to bay. That's already a struggle for these boats.

Trying to get to a safe anchorage in 50+ 73 gusts, is very tiring, but we dropped anchor and waited 2 days of wind and rain. After a 4 month jaunt we headed home, with No issues whatsoever about the integrity of our boat. She loves the strong conditions and we usually set the boat at 40/30 deg and I love how she gets in the groove at 32 degrees and she will virtually sail itself. The weather can be very unpredictable on the west coast, and the seas can change in minutes. We are 75 and 77 years of age and go out for a sail ⛵ in all sorts of weather in our VERY SAFE BENETEAU.

Having a Lagoon 440, the first evidence of this design flaw shows up there on the port side of the boat as well. I'm getting ready to haul and fix that this fall/winter. My guess is when they extended the 440 to 450, they failed to take into account the extra width of the boat and so it shows up more there. I've never been inside a 440 that did not have the visible part of the port cabin door surround broken. I've always assumed it was because that was the next place in the boat to absorb that extra stress. My boat makes lots of noise even when sitting at anchor so we'll be pulling pieces out to secure them with fiberglass and stop the excess squeaking. I know they won't be helping with my repairs but luckily I'm in Mexico where the labor is cheap.

When you watch Parlay (and others) it is not just the bulkheads, once they start digging they often find allsorts of quality control issues. My guess is that the engineers did their calculations and finite stress analysis with the assumption of good to perfect manufacturing. For a number of years Lagoon could not produce boats fast enough to meet the demand and quality was allowed to slip.

[@davidweeks1997]

I think trimarans are the perfect sailing vessel. Fast, roomy, super tough. The center hull can handle the sail shrouds, and provide motor/engine drive, while the amas provide stability and LOTS of additional space.

Considering all the forces working on a two-hull boat mentioned in the video, it does baffle me slightly that, even with a flydeck on top, those boats are just made of plywood! The repair kit seems to have some metal involved. I'd say: high time! Notwithstanding environmental concerns, it is my belief that for stability's sake, either more fiber/resin or some more metal components need to be installed here, to give the necessary strength.

Can you show the difference between other mass produced cats like Leopard? Are the bulk heads too small? Are they in the wrong location? I would be interested in a marine architects opinion as well. Thank you for your great videos!

[@brucesinclair-ji9ur]

What suprise me is that lagoon has not came out to defend there reputation. They have not said what they are doing to change. The design changes needed to prevent this from happening to new yachts.

[@stevesteel6066]

Are you going to go sailing? Parlay documented this issue a year ago, along with bad tabbing of the remaining bulkhead issues!

[@bryansmith1920]

Their you go I'm a Brit that wants to know what my cousin across the sea is sailing this season, And with all our great Nations outputs of the Best seakeeping vessels in the world you mentioned the F word, I must admit to love racing Beneteau yacht's in the Med But I've won regattas in the Med with Moody 31 Yachts back in the 1980's against light weight F kit, not surprised to find Profit making is making a comeback to Cause of death of those that go down to the sea again,

AAAH Hestia and the Anzac bridge Sydney

"...and like me, she's built for comfort" 😂

[@jodiplock4784]

Interesting

[@coffeeandcrypt1202]

Was this a problem on the 440 also?

[@MayonaiseSailor]

memo to self ... never buy a lagoon ... and to be extra safe stay away from beneteaux ... thx

[@saltyviking2225]

Love your vids unfortunately I can't afford to support as I have low income and paying my Catalina 34 .I do have hope to sail it to Europe from pacific mexico.i would love to see episode of how to make Catalina 34 safe for crossing Atlantic or similar boat.i am sure many production boat owners would like that

[@dongreco6886]

"still Safe" and "no mast problems" ? Parlay was about to cross Pacific, then the rigging suddenly went slack.

[@MiQBohlin]

It's brave to pick up this subject again! Like hitting a wasp nest 😉All "knowledgeable" haste to make hash comments about cat's… and especially Lagoons… I think you are doing the right thing to put the whole fiasko into a decent perspective. Keep it up! Make a part two of this!

[@LadyKSailing]

Thank you!!! Seriously. Much appreciate.

[@MiQBohlin]

@@LadyKSailing The subject is far bigger than catamarans or Lagoon or even Beneteau - this addresses the whole industry 💪 And its urgent! Keep on making this analyse 🔍

[@Four_Words_And_Much_More]

Making it good. The willingness to repair defects must be a core concept in any manufacturer. This is not an optional idea. My concern is much simpler. Lagoon demonstrated they do NOT have a design build process that absolutely prevents structural failures. An example of an company that does have a design build process that prevents these failures is Toyota. Design-build for a moving device such as a boat or car is not straightforward. It involves a lot of historical knowledge that is contained in chief engineer's head. In the best companies there are deep manuals that contain deep proprietary information about design build processes. This information is never shared outside the company. The stress analysis of a catamaran is not a simple engineering problem. The two hulls and mast in the middle present analysis problems that are not common to most structural engineers. Finite element analysis by computer is the primary solution used today. It is robust and requires a high-powered computer with specially trained engineers. So I do not give Lagoon a pass on this one. They flunked my standard. They do not have a process that prevents this from happening again.

[@robertcairns4207]

Will you take a look at Leopard?

[@jimczerwinski4951]

So will the repair last?

[@johnrathbun2943]

If you can't handle the truth than stay away from people that throw stones!

[@dalb08]

Why don't the other Lagoon models have the same problem? What are the differences in the designs that prevent bulkhead fractures?

[@supertuscans9512]

The question is : is this a repair or a fix? I.e is it a flaw in the design issue or a materials failure issue?

[@Chacarruna]

I wonder, as future catamaran owner, if this issue is driven the used one’s price down…

[@julescapozzi]

I answer as someone that just placed an offer on one... not enough.

[@seanrhone5306]

I don't think Lagoon did the right thing. Parlay spoke about the "kit" and it sounded more like a patch, than a real fix. Yes the patch "might" make things better but it's not a real fix, IMO. I was also shocked at the flimsiness of the bulkheads! What looks like a half inch plywood with two small support pieces, seems "mickey mouse" on a yacht that is supposed to be rugged enough to go around the world!

[@seandelaney1700]

I'm more artist than engineer and I am just shocked by this design. I don't need math to know the forces are intense and this is the obvious stress point in these designs. The older?, homemade? trimaran next to me just came back from trying to cross the Pacific because his hull has a 4 inch crack. As these boats are clearly not built for speed they should be built more stout.

[@JohnGBeckett]

Lagoon didn't "do the right thing" until there was massive pressure on them. There are still other people with brand new boats with major flaws that Lagoon simply refuse to do anything about. When a builder has to be forced to do the right thing, you can never trust them again. In this case Lagoon "doing the right thing" is simply part of their PR budget, not any indication of any principles.

[@carlwegener7544]

All this just makes me like Wharrams more if I go with a catamaran for my next boat.

[@georgewashington7444]

Yup! A well built Wharram is the way to go with Cats. IMO

[@unstoppable5417]

It appears lagoon took a few short cuts to save on money.
