I know most will never see the light but what the hell. Here we go
How about adding a delta Pier for subs, some how ship anchors, Submarine Tenders, new aircraft Carrier models as long with ddg's,Ship Horns,Running lights you know red and green,a kilo with the pump jet,long piers say around 800 ft or so maybe about 30 50 ft wide nothing fancy just a long Grey pier. And some type pf lie break wall so we can mack harbors like Guam's. just some ideas i put a bunch of light houses together to make harbor and it sucked.

How about more civil ships,
