Why is my boat moving horizontal , when i scripted it for vertical ?

i am a bit new in unity , but i see a youtube tutorial and got the script for my purpose ( it worked ) but instead of moving vertical it is moving horizontal . help please !!!!

 using UnityEngine;
 using System.Collections;
 
 public class Boat : MonoBehaviour {
     public float turnSpeed = 10000f;
     public float accellerateSpeed = 10000f;
 
     private Rigidbody rbody;
 
     // Use this for initialization
     void Start()
     {
         rbody = GetComponent<Rigidbody>();
     }
 
     // Update is called once per frame
     void Update()
     {
         float h = Input.GetAxis("Horizontal");
         float v = Input.GetAxis("Vertical");
 
         rbody.AddTorque(0f, v * turnSpeed * Time.deltaTime, 0f);
         rbody.AddForce(transform.forward * h * accellerateSpeed * Time.deltaTime);
 
 
     }
 }
