Lagoon 42 - Balsa core or foam core

Hi folks,
I'm considering a Lagoon 42 as my new home for living abroad and sailing the world (buying a used one owners version 2023 / 2024). But, considering a used boat with unknown pre-life, my biggest concerns are about sustainability. Balsa is known as much more critical than closed foam regarding leaks through thru hulls, hatches or anything else.
Here is my question: Which core uses Lagoon for the new L42 (above waterline)? And, do they use solid GPR below waterline?
Next question: Are there any other suggestions for me in a range between 40 to 46 ft?
My budget: 350 k€ plus up to 80 k€ for refits & upgrades.

Cheers
Dirk

It’s balsa above and solid below.

Re: Lagoon 42 - Balsa core or foam core

The specs for the new 42 say balsa core for hull and deck, no mention of solid laminate below the water line, as in the 450S spec, per the specification brochures on their website. Maybe they forgot to mention it or a method to help reduce weight. FP and Leopard also now using cores below the waterline I think but don't know for sure.



I understand that the balsa core being used is small endgrain blocks that are epoxied together so that water intrusion is limited to the block. A while back there was another post showing photos of a FP with damage and the surrounding blocks.

Re: Lagoon 42 - Balsa core or foam core

Some sources say the Lagoon 46 is balsa cored below the waterline. Might need to ask lagoon to confirm since in the brochure it only says hull.

Lagoon 46

But I always wondered if the resin can really get between the balsa block since they are usually bent the other way thereby closing the gap

Except the Lagoon is infused polyester. Even epoxy sealed balsa can have delamination problems due to the anaerobic mold, black streaks in the wood. Limiting the oxygen will only prorogate growth.

I think all Lagoons, including Lagoon TPI are all balsa cored. The same for Fountaine Pajot they are balsa cored except some old ones like the Belize 43, the Bahia 46 and maybe some others old ones. The new ones they are balsa cored in the hulls and foam cored in the deck (according to a guy who visited the factory and reported here in the forum).
Leopard also, they are all balsa cored.


Check this YT channel, this guy bought a hurricane damaged Lagoon 450 (yes I Know it's not a L42). You can clearly see the core is balsa.

Re: Lagoon 42 - Balsa core or foam core

Sorry, I’m not familiar with the catamaran in the photos. Was this damage done by fierce bad orcas or was it a hungry ice bear?

Actually Fountain Pajot boats were all solid below the waterline and foam cored above until just the last couple years.

Re: Lagoon 42 - Balsa core or foam core

Hi folks,
thx a lot for the information (and the information beside Lagoon).
Since the YT about the L440, where not only the balsa core was damaged (major built desasters by Lagoon) I don't know if it's a good idea to buy a used L42. And the more I think about it the less I'm convinced.
Maybe it's better to go for a Max 42SC? Maybe to get a complete hull (as a deckfreight to Germany) and to make the interior by myself? Technically and timely I'm able to do it (from 2024 on). But not to build the hull.
The biggest advantage would be, that I then know every piece and every corner of the boat.

Last paragraphs are off topic, only my thoughts.

Again, thx for your comments.

Cheers
Dirk

Do you wanna go sailing or building a boat the next 10 years?

Suggest to get a older Catana, they are foam cored, refit to your liking and Go really sailing.

Re: Lagoon 42 - Balsa core or foam core

Thx. I know and follow them since the beginning.

And decided not to go the exact same road. However I like (not to say love) the Max 42 (and it would be a 44 if built by the yard itself (2 more feet at the stern).

Cheers
Dirk
