Firstly I love Lagoon 45's. Have chartered them many times. I have been watching a you tube series on rebuilding a hurricane damaged lagoon 45. Over the time of this series they have gone over every part of the 45. The thing that is really interesting is they found bulkhead issues with their boat. After 5 weeks of repair and trying to get direction from Lagoon on a repair procedure other 45 owners began chiming in about the same issues with their boats. This as blown up to where there are 45 owner groups on face book and other places.
Here is the video that details the problem and what has happened. you can follow the whole series that led up to this video. Very interesting. Enjoy https://www.youtube.com/watch?v=zoXWKz4Odsg&t=506s

Not good advertising for lagoon.

No bulkhead problems on the brand of boat you are stood on in your profile picture Steve
