I have tried to post some pictures but it said the file size was too large. Pictures are on my I phone along with some video, I do not know how to reduce the size of the jpeg so I can attach it, certainly I think the video would not be possible. There are a lot of parts in this boat and it took a long time to build, however the only part that care is required is fitting the 2 decks, fitting the lower deck as in plans would not have given a big enough gap to fit the cabin that goes between them. I suggest you tape upper deck in place, then build cabin that fits between decks and tape this to upper deck this will allow you to position lower deck at the correct height.
The model boats magazine article is from a long time ago, I will search my shed to see if I can find it
