There was this simulator of that hyroplaning / hydrofoil sailboat that may have set the water speed record for sailing... they had their own simulator with the complete code and source available (for the mac). Another awesome sim (imho) is the Charles River RC Simulator, because its physics is so nice. Then other simulators I know of are like the weather simulations used for predictive models, but I think those are all fortran running on big iron. Lots of fun! Be sure to report back here with what you have.
