Hello Bob! I am aware of the differences between the two ship classes. But from what I read on the web, the hulls of both classes of ships are the same. Since originally the tiger-class ship hulls were minotaur-class ship hulls that were never finished. Therefore, in theory, the frames of both types of ships should be the same. Obviously the superstructure is totally different and that's the hard part! At the moment I am going to dedicate myself to continue with my old model, the Meko 360.
Cheers! Gian.
