Lagoon 450F Bulkhead repair kit

You remember this bulkhead inspection we shared with you a few weeks back?
Well, this Lagoon 450F unit from 2011 was indeed affected by the now infamous 450 bulkhead-gate. However, Lagoon is stepping up to deal with this properly, as they did with the previous units we encountered over the same issue.

The owners submitted the photos of the inspection on both Starboard and Port side to the Lagoon service center, and after some more questioning on the boat’s history (nothing to report of significance), this unit was added to their bulkhead-solving listing.

After a few weeks, we received the repair kit, properly packaged in three boxes.

Those are the metal U-shaped frames which will reinforce the bulkhead on both sides.

Even the Sikaflex is included in the repair kit.

Since we are expected to break down the forward doors rims, new ones are included in the repair kit.


We will now proceed with the reinforcement according to Lagoon’s instruction, validated by the VDLP naval architect of this range.


In the meantime, should you have concerns about your own bulkhead, you can look out for potential bulkhead failure tale signs:

  • Panel behind the cabin sofa cushions, just next to the mast compression spot, bulking out, or using only three out of the original four screws (we’ve seen once this panel support area so twisted, it was using only two screws).
  • Port and Starboard side doors to forward cabins (or forward head in owner version) no longer square.

And since this is quite a sensitive matter, with less-than accurate information published into sailor’s forums by frustrated owners or by other catamaran brands trolls, may I suggest you read the official information provided by Lagoon on this matter before making up your mind?
