Can't move forwards properly

Hi all, I have a problem with the boat I’m trying to make and the way it moves. When using the forward keys the boat moves in the forward view of the world and not of the boat.

Am I approaching this in the best way or is there a different script that could solve my problem.

Any help would be appreciated,

Code (csharp):

1.  
2.  
3. var rowSpeed = 20;
4. var rowtateSpeed = 30;
5.  
6.  
7. function FixedUpdate () {
8.    
9.     //this bit controls forward and backward, this line turns the up and down keys into a value from -1 to 1
10.     var forwardSpeed = Input.GetAxis ("Vertical");
11.    
12.     //this line multiplies that last variable by 20
13.     fwdSpeed = forwardSpeed*rowSpeed;
14.    
15.     //Adds a force to the forward axis (Z) by the variable above
16.     rigidbody.AddForce(Vector3.forward * fwdSpeed);
17.     //end forward/backward bit
18.    
19.    
20.     // bit controls the rotation. use left and right keys to control rotation....
21.  
22.     var spinSpeed = Input.GetAxis ("Horizontal");
23.    
24.     // times the variable to give it higher speed
25.     spinnerSpeed = spinSpeed*rowtateSpeed;
26.    
27.    
28.     // rotates it round the y axis
29.     var eulerAngleVelocity = Vector3 (0, spinnerSpeed, 0);
30.     var deltaRotation = Quaternion.Euler(eulerAngleVelocity * Time.deltaTime);
31.     rigidbody.MoveRotation(rigidbody.rotation * deltaRotation);
32.  
33.    
34.    
35. }
36.  
37.  
38.  

 

Instead of
rigidbody.AddForce(Vector3.forward * fwdSpeed);

try with
rigidbody.AddForce(transform.TransformDirection(Vector3.forward )* fwdSpeed);

or
rigidbody.AddRelativeForce(Vector3.forward * fwdSpeed);

 

Hey, thanks a lot, i'll give them both a try.
