Need help to put together 2 scripts

Hi I want to put together these 2 scripts but I have no idea how can you help? using UnityEngine; using System.Collections;

 namespace OceanSurfaceEffects
 {
     /// <summary>
     /// Add to a game object to make it float on the water.
     /// This is just a rough method to demonstrate how to
     /// sample the wave height. You will likely need to 
     /// improve on this for a proper game.
     /// 
     /// There must a game object called Ocean with a Ocean script
     /// for this to work.
     /// </summary>
     public class AddBuoyancy : MonoBehaviour 
     {
         /// <summary>
         /// The m_ocean script.
         /// </summary>
         Ocean m_ocean;
 
         /// <summary>
         /// Increase the spread for wider objects.
         /// </summary>
         public float m_spread = 1.0f;
 
         /// <summary>
         /// Adjust offset to make the object float
         /// higher or lower in the water.
         /// </summary>
         public float m_offset = 0.0f;
 
         /// <summary>
         /// Increase to make the object tilt more.
         /// </summary>
         public float m_tilt = 20.0f;
 
         void Start() 
         {
 
             GameObject ocean = GameObject.Find("Ocean");
             
             if(ocean == null)
             {
                 Debug.Log("Could not find ocean game object");    
                 return;
             }
             
             m_ocean = ocean.GetComponent<Ocean>();
             
             if(m_ocean == null)
                 Debug.Log("Could not find ocean script");
         
         }
         
         void LateUpdate() 
         {
             if(m_ocean)
             {
                 Vector3 pos = transform.position;
 
                 float ht0 = m_ocean.SampleHeight(pos + new Vector3(m_spread,0,0));
                 float ht1 = m_ocean.SampleHeight(pos + new Vector3(-m_spread,0,0));
                 float ht2 = m_ocean.SampleHeight(pos + new Vector3(0,0,m_spread));
                 float ht3 = m_ocean.SampleHeight(pos + new Vector3(0,0,-m_spread));
                 
                 pos.y = (ht0+ht1+ht2+ht3)/4.0f + m_offset;
 
                 float dx = ht0 - ht1;
                 float dz = ht2 - ht3;
                 
                 transform.position = pos;
                 
                 transform.localEulerAngles = new Vector3(-dz*m_tilt,0,dx*m_tilt);
             }
         }
     }
 
 }

and the other one:

 var speed = 1.0;

 function signedSqrt( x ){
 
     var r = Mathf.Sqrt(Mathf.Abs( x ));
 
     if( x < 0 ){
 
         return -r;
 
     } else {
 
         return r;
 
     }
 
 }
 
 
 
 function Update () {
 
     // Bobbing
 
     elapsed += Time.deltaTime;
 
     transform.position.y = seaLevel + bob * Mathf.Sin(elapsed * bobFrequency * (Mathf.PI * 2));
 
     
 
     // Steering
 
     rudder += Input.GetAxis("Horizontal") * rudderDelta * Time.deltaTime;
 
     if( rudder > maxRudder ){
 
         rudder = maxRudder;
 
     } else if ( rudder < -maxRudder ){
 
         rudder = -maxRudder;
 
     }
 
     heading = (heading + rudder * Time.deltaTime * signedSqrt(speed)) % 360;
 
     // transform.Rotate(0, rudder * Time.deltaTime, 0);
 
     transform.eulerAngles.y = heading;
 
     transform.eulerAngles.z = -rudder;
 
     
 
     if( rudderControl ){
 
         rudderAngle = ((-60 * rudder)/maxRudder + heading) % 360;
 
         //rudderControl.transform.localEulerAngles.y = (70 * rudderAngle) % 360;
 
         rudderControl.transform.eulerAngles = Vector3(0, rudderAngle, 0);
 
     }
 
     
 
     // Sail
 
     speed += Input.GetAxis("Vertical") * acceleration * Time.deltaTime;
 
     if( speed > maxspeed ){
 
         speed = maxspeed;
 
     } else if ( speed < minspeed ){
 
         speed = minspeed;
 
     }
 
     
 
      transform.Translate(-speed * Time.deltaTime,0,0);
 
 }
 
 
 
 function Awake (){
 
     seaLevel = transform.position.y;
 
     rudderControl = GameObject.Find("rudderControl");
 
 }
