First there was Ship Simulator, and now there is Extremes of it. Something like that. Anyway, Paradox Interactive have sent word that the greatest ship-simulation of all time is now even greater, thanks to a new game scheduled to arrive in the harbour of our attentions in early 2010. The new game will once again feature careful navigation of "hovercraft, coast guard interceptors, mammoth tankers, tugs, and cruise liners" as you travel famous (and obscure) ports around the world while traversing "extreme, and ultra-realistic weather conditions." Still no full-physics destruction model though, which I think would make it.
Nonetheless I'll say it now: next year is hot for ships. (Trailer below decks, of course.)
