So, Jimmy Skiff.  Trailer.  Sailing rig.  May I ask for advice on putting all this together in a way that avoids unfortunate incidents on the freeway?  I can figure out girth straps all right, and I can build a boom crutch that will fit into the mast step for the forward end of the mast.  How do I secure the other end of the mast to keep it steady?  Suggestions for a sail cover---I've laced on my sail, so the sailing rig does not come apart (and on the other hand, steps, and it's good to go)?  Does CLC sell a sail cover, or do I have to source one locally?

 Thanks!
