There's a lot of good ideas there. We have no club location where I sail. Another problem is that with one exception the water levels are not constant, over a season they can drop 20 or 30 feet. Some times they are low to begin with and don't recuperate for a year or three. Not only does that make for difficulty landing it makes it difficult to remember and forecast the depth of the water in places where you know there is a sand bar but you don't know how deep. At the lake which has a constant level, or is suppose to, it is operated and controlled by The Army Core of Engineers so they aren't likely to allow privet moorings. They have all the boat traffic channeled into a narrow area. (There is another landing where there is a dock, but the drop off is really steep, but that's an idea). On the H16 I can drop the main and sail in on the jib, maybe I could learn to drop the main on the F16 and paddle in except for when the wind is strong and off shore....
Still, if I can strengthen that one hull I'd be okay with the sliders. I can pick up the bow and carry it up to the point where there is sliders under each end.
I think I have to cut off that outer layer of gel coat anyway as it is so brittle and not well stuck. I've pealed off 1 inch squares of gel with a razor blade type gasket scraper. Then there are places where it is really well bonded, maybe even chemically bonded. If I can cut down through that, then lay a piece of that thin 0.020 inch fiber glass the length of the boat and maybe up to the chine on the sides I think it would be strong. I don't know how much weight that would add. Remember, I can add 5 or 7 pounds just to make the hulls equal.
Now that I think of it, maybe I'd find the beach wheels easier to use if I didn't have the cradles on it. Hard enough just to get the contraption under the hulls and tied on somewhere. I still have the problem of rigging the main when it is blowing strong enough to make white caps. I have a twelve to one external down haul and that takes a lot of time and hassle. I saw a picture where a Lady (maybe in Florida) had a long shackle in the down haul hole in the foot of the main, that made me think I might not have to re-thread the whole mess each time. I think rigging the main has contributed to the hull abuse.
