Yes, it is screwed, not bolted, which all the literature says is a drawback because not sufficiently strong. The genoa track is bolted, but not all my bolts go through both the hull and deck laminate, because of its position on the cap rail. I heard that Morgan put resin and mat between the hull and deck joint, but mine appears to be something else--I hope it is 5200. From what I have read, the lack of through bolts is a weakness, but one I decided to live with. The Alberg 37s and Whitby 42s were riveted--not much better than screws, and they are considered stout boats. My rail does not leak, as far as I can tell. I suppose with lots of work one could take the cap rail off and put in through bolts. I once saw an Allied Luders design, I think it was, whose foredeck had peeled up in heavy going. Everything is a compromise.
