"I absolutely love this set. It is much bigger than I thought it would be (which is NOT a complaint!). You 1st build it as the shipwreck. You can then change it over to a complete ship by removing some parts and adding some new ones. Let me warn you, tho... if you decide you want to change it from a complete ship back to the shipwreck, be prepared for some frustration! It is fairly simple to go from shipwreck to complete ship. BUT going back to the shipwreck is not as simple as just reversing the steps. I don't think it was really designed to change back. It was a pain (for me, anyway)! I personally prefer the shipwreck setup."
