Why wont the GameObject move?

The object has a rigidbody attached, but I haven't referenced it here as I am not using it, and the object is supposed to move when I press H, but it only does the Debug.Log command. How do I fix this, thanks. (There is also no character controller on it as it is not needed).

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class BoatPlayerController : MonoBehaviour
 {
     public float moveSpeed = 10.0f;
     public Vector3 newPosition;
     public GameObject mainCamera;
     public GameObject boatCamera;
     public GameObject boat;
 
     // Start is called before the first frame update
     void Start()
     {
         newPosition = boat.transform.position;
     }
 
     // Update is called once per frame
     void Update()
     {
         if(Input.GetKeyDown(KeyCode.H))
         {
             Debug.Log("Move Boat UP");
             newPosition = transform.forward * moveSpeed;
         }
     }
 }
