Might be a pretty gutsy move to go & ask a something as obscure like that in a little kids' show community, but whatever. I wonder if there are anyone here who likes / has interest in ships (not just the Titanic movie): perhaps lives in a big port with plenty of ships & traffic there, makes photos of ships, stares at the AIS & tracks a beloved ship, has some knowledge in ship theory & history, makes scale models & whatnot. Although I'm not ultimate at any of that & dropped eventually some of them, but still am a devoted ship enthusiast.
