BoxCollider2D rotation not the same as GameObject rotation

Hi all,
I’m having a bit of an issue with a BoxCollider2D I have on my GameObject. When I rotate the GameObject, the BoxCollider2D rotates with it, but not as fast. Is there a way to get the BoxCollider2D to move at the same rate as the GameObject? I feel like I’m missing something obvious.

Before rotation:

After rotation:

Below is my code for the movement of the player:

using UnityEngine;
using System.Collections;

public class PlayerMovement : MonoBehaviour {

	Animator anim;
	Rigidbody2D rbody;
	float speed = 0f;
	public float moveSpeed = 0.6f;
	public float acceleration = 0.2f;
	public int turnSpeed = 20;
	bool sails = false;

	// Use this for initialization
	void Start () {
	
		anim = GetComponentInChildren<Animator> ();
		rbody = GetComponent<Rigidbody2D> ();
	}

	// Update is called once per frame
	void Update () {

		if (sails) {
			rbody.transform.Translate (transform.right * (speed * Time.deltaTime));
			speed += acceleration * Time.deltaTime;

			if (speed > moveSpeed)
				speed = moveSpeed;

			if (Input.GetKey (KeyCode.LeftArrow)) {
				rbody.transform.Rotate (0,0,turnSpeed * Time.deltaTime);
			}

			if (Input.GetKey (KeyCode.RightArrow)) {
				rbody.transform.Rotate (0,0,-turnSpeed * Time.deltaTime);
			}
		}

		if (!sails) {

			rbody.transform.Translate (transform.right * (speed * Time.deltaTime));
			speed += -acceleration * Time.deltaTime;

			if (speed < 0f)
				speed = 0f;
		}

		if (Input.GetKeyDown (KeyCode.Space)) {
			sails = !sails;
			anim.SetBool ("sailsDown", sails);
		}
	}
}
