I will have a more modern bow representing a newer container ship. Actually, it will be a lot easier to master, mold and cast than the tanker bow. Less complicated for sure, and shorter, requiring a lot less molding and casting materials. It's still the mold cost, btw, that really determines what I can build.
Not everyone is building UCCs and Panamaxes--there are plenty of new 350'-550' general purpose/container ships built in just the last ten years. And these smaller ships do come into POLA/LB--there's a wharf or three or more near the LB Convention Center just for them. Sorry I didn't have time to take pictures last time I was there back in--yowsa--2007.
Perhaps a backdrop of a Gen 2 or 3 or 4 ships with a model of the modern feeder ships in the foreground? A 500' ship, even with an older tanker/cargo bow rather than the more modern (and simple) bow, is still very prevalent in POLA/PB, PONY/NJ and Ft. Lauderdale, the only ports I'm familiar with.
The new container ships are bigger than Nimitz-class aircraft carriers!
