Hi,
A complete simulation of the ferry service between the port of Dover and Calais would be intresting as this is the worlds busiest shipping route of the world. (Dover Strait).
Also the ports of Dunkerque Zeebrugge and Ostend would be a nice add-on.
The ferry compagnies on the Dover service are P&O, Norfolkline and Seafrance.
It would also more realistic with lightbuoys, harbourlights and -ships.
All these stuff are perhaps ideas for an Add-on for shipsim 2008, or a next release of Shipsim.
succes,
Henk.
