Why has no one ever thought of a PowerBoat sim....?
I don't know, but I'd buy one if there was!
Well I love King of Shaves (Now Negotiator) myself, but that's just me. My mother used to work
at Plymouth Dome (now closed down, MASSIVE blunder by Plymouth City Council
) and the view from her office was probably the best view anyone can get, or if not, there was a camera on the roof of the dome and a big observation gallery where you could control it, now THAT was the best view
There are some other simulators, Virtual Sailor (http://www.hangsim.com/vs/) being a popular one, but you could try Rigs Of Rods (http://www.rigsofrods.com) (i'm addicted to this!) but nothing as high quality as Ship Sim, because it's so hard to modify.
Sorry I can't be of a little more help!
