I hear you I have many with mine as well but we work with what we have and we will be the only one who knows in the end.Thanks. Yes, I agree that the mother ship shows a different arrangement in the region of the waterway. I am not at all satisfied with my work but I'm not sure if I will pursue a fix. My ship model is POB and I did not appreciate the implications of that. I should have planned to cut off the bullhead frames from the very beginning. Alas. My first build and it contains many shortcomings. As for you - keep up the good work!
