Sorry, this was many years ago in the days of film cameras when no one took photos of mundane projects.
I do remember some construction details. There were two infill areas constructed of 6mm ply. In retrospect, this was probably too thin, but it was only a very lightweight boat and wanted to keep the added weight down. It therefore required a rather extensive web of stringers and ribs. These were from about 10x70mm hardwood epoxied to the underside of the ply to eliminate the flex.
The end result was supported by the existing bed and some frames standing on the floor made from the above hardwood.
As well as a much larger bed, there was additional storage
created under the extension for very little extra weight, but it could be converted back to standard in few minutes.
In a one design class the yacht became quite famous as the one with the “passion pit”
For a 42 foot cruising yacht, I would be much less concerned about the weight, which would simplifly the construction, but the principals still apply. A simple, temporary structure is not difficult to assemble and would prove the concept
, and help refine the final design without significant commitment.
If this proves successful more extensive and permanent remodelling can be undertaken with confidence.
A large primary berth (bed) is a great luxury on board a yacht that in my opinion is more important from a comfort/convince point of view than many of the “extras” available.
