Headdead, Welcome to the sailing life. All the youtube videos I pull up have the NACRA 5.2 with a boom so I would say that it's missing. On the lower part of the mast you should see a place to pin the boom. All cat's with one have some way to attach the boom to the mast. Good luck with it. Remember Google knows more than us...
I am getting ready for Irma's visit.
