Such a crack will happen on any catamaran irrespectibally whether it is a 180 kg F18, 75 kg A-cat or a 18 ton Groupama 3 when an internal element like a bulkhead or subdeck comes undone or cracks due to production errors and no longer supports the hull skin.

As a result such damage has happened to pretty much any design out there in the world today and will continue to happen in the future. Boat builders are still not applying aeronautical or space-age quality control systems; as such these incidental mishaps are recurring.

More importantly is whether the company building/selling the boat takes responsibility and handles the warrantee in a proper way. That has always happened thus far.
