I just bought a 1973 Javelin. It has a one-piece mast (23 ft) that apparently is to be set through a hole in the foredeck and sit on a mast step down inside the cuddy. I have no idea how to set up the mast, since it's not hinged at deck level, as my previous boats had it. How does one go about setting the mast in this situation? I'm not capable of manhandling it into place while climbing around on my wobbly trailer.
