Glad you didn't give up.
The sight of and appreciation for the model by fellow model boaters or passers-by at the pond should give you plentiful reward for the plight you have gone through with her build.
She looks to me to be of the common Ulstein design for AHTS vessels.
Could you do me a favour and post a few shots of her stern, especially of the underwater part with shaft/prop/nozzle arrangement and the breadth of the skeg?
The reason for my asking is that I reconstructed a lines plan of the Ulstein A102 from a lousy GA copy within a spec sheet, and I am still in doubt whether I have guessed the shape of the stern correctly.
I am particularly unsure about the breadth of the skeg because I haven't found any dry-dock photos.
I estimated a breadth of 1.6 m which I believe is to slim since the skeg should provide sufficient space for the stern thrusters.
To me it looks however, as if all Ulstein AHTS designs more or less have the same stern design.
Btw, these should resemble the hull lines of the BOURBON DOLPHIN which due to her tragic sinking in April 2007 after only half a year after her delivery from the builders should inadvertently have displayed the very part that interests me when she floated some two days keel up in the North Sea before she sank to the sea bottom in 1100 m where she now lies upright on her keel.
Unfortunately, all the photos that I have discovered so far in the Internet that depict this state are too small and of too poor quality to really be useful.
