Moving a model on button press???

How would I go about making my ship move when Im sat on a seat? Like if I pressed W it go forwards, S backwards and so on. Its a model, thats anchored and the 'water' im using in a huge mesh.

Im not asking for the script (Although that would be good c;) but a way Id go about doing this is what im really asking for. Thanks C: ~MrLego

To detect the wasd movements, I suggest you to read this article. If your ship is anchored, you have to use some CFraming, and to make it smooth, a loop that checks the keyboard keys, if they are pressed, it keeps moving.
