John: you can find instructions on how to bolt through the transom by going to the Mongomery Sailboats list archives and hitting on montgomery boats newsletters. Go to Fall, 1996, page 3. There you will find the article. If you want to see how the ladder looks on my M15, go to MSOG photo site of M15s and hit on "Really". One of the photos gives a clear picture of how it looks. Hit on it to enlarge the photo. Rich Cottrell
