Have been looking at the default passenger ferry terminals the last couple of days, doing my harbour bus.
Just realized how ugly they are (the terminals, that is), I was hoping some one would do a new terminal.
Thinking of doing one myself, but it could not heard to have more to choose from.
The only one I can think of off the top of my head is Goldiva's Water Taxi (http://www.simtropolis.com/stex/index.cfm?id=3355). I'm sure you could find one on a Japanese site ;D. In fact, I think I saw one recently, but can't remember where...
I think this is the Japanese one you are thinking of bwatterud. [ LINKIE (http://tokitoko.hp.infoseek.co.jp/lot_others.htm) ] It is NOB's. $%#Ninj2 Great stuff there that is for sure.

Haven't found many good pictures of a ferry wharf, (still looking) but this ferry symbol might be of use to somebody (might make a great sign):

EDIT: here's a small image of an unimportant Sydney wharf:

From my exposure to ferry wharves, though, they tend to be quite simple (and Sydney actually has quite an extensive ferry system).
I think these two ferry terminals might suit your water taxis particularly well Vester...
