I would have thought, that at a dinghy size, a wing-sail could not be constructed so the solid pieces slotted together and a fabric or film covering was pulled over the top and tensioned, avoiding the need for a solid-construction wing to be stored flat somewhere which I accept would take up a ton of room and be awkward, to say the least, for a fleet of boats

One day, the sun will eventually expand to become a red giant and will swallow pretty much the entire solar system, so it'll all be pretty academic.

I wonder what the relative lifetime environmental impact of wood and plastic boats is, given repainting, microplastic from sanding back paint, etc etc.

Wing sails were of course developed in small boats, notably the C Class catamarans, long before they were seen in the AC, but the spectacular inconvenience of off the water handling is a killer. A C class regatta demands covered storage for every boat, including enough space for rigs to be demounted and stored under cover out of the wind. Given a fleet of 30 or 40 boats that's a very sizable requirement in space and expense hiring marquees.

Said it before, will again, the wing sails of the AC world will make their way down the pyramid and end up on dinghies in the near future, as boats increase in speed development from soft sails is inevitable, likely also joined with foils, flying systems (i.e. developments on the 'wand' ) and steering systems.

I'd like to see more effort go into environmentally conscious development given the cr@p we are all in if we don't change our ways ... metals masts can, I guess be recycled, but FRP/GRP isn't very friendly so maybe some kind of second wind for wood construction? but that needs last-for-a-thousand-years glues??

My (inland) club allows wing foilers. We have a few.

Looks deadly dull compared to wind surfing. Foils at a crazy low speed, but not quick. Probably lots of fun in waves, but we don't have those.

Very portable, which is nice, but I'm not the slightest bit tempted.

Well talking of 'foiling' the latest step change is the advent of 'Wing foiling' which has been gathering momentum this last couple of years. This involves holding an inflatable 'wing' which can either be used to propel a SUP or something smaller with a foil beneath it.

So what I hear y'all groaning, well 'what' is that some inland waters have opened up to the use of wing foils with the resulting influx. Kites have never been permitted inland, but Wing foils have no lines to tangle around overhead power lines or around the propellors of rescue boats and travel at the moment at slower speeds.

There are naturally growing wing foil race championships which I have to say visually look far more comfortable andf stylish than the kite foil racing arena that has foolishly adopted none water relaunchable foil kites and has a technique requirement off the scale compared even to windsurfing and windsurf foiling.

Wing foiling is also way cheaper and more accessible than wind or kite foiling, so expect to see more of it and if I were an inland club looking for more young members doing something visually different and potentially exciting, I'd get ready to embrace the activity which in skilled hands I've even seen carried out in marinas amongst the moorings as it's suitable for gusty shifty wind because of the high amount of created wind used in the application once pumped up onto the foils.

When it isn't, they are just very wobbly and quite slow displacement boats.

The thing that did impress me was the work rate of the better sailors; "bouncing" the boat on its foils to get the hull out the water, then sheeting and steering.like mad to keep it foiling.

But I'd miss the feel of the boat bouncing and crashing over the water.

Not sure foiling is "the future of sailing" .. but possibly does count as a significant step change in a particular direction. And note that the fastest windsurfers are, ultimately, still the non foilers .. the foils have more drag than a board that's planing.

Not tried foiling, too old and lacking agility for a Moth but definitely considering a windsurfing foil setup. What my reading has suggested is that foils have an upper speed limit beyond which they won't go so you need different foils for different conditions which rapidly gets super expensive. If I do give it a go they'll be large area for low speed lift (and slower crashes LOL).

I have owned my K1 for 10 years now, although unused a couple of years.
It has only fallen over once, at a Boxing Day regatta, where I was the only non Laser silly enough to go out.  A big gust came along when I wasn’t paying attention before the start, and the boat capsized.  While I was thinking “what do I do now” the boat popped up again.
I have also sailed the Laser Stratos Keel quite a lot and I found the K1 came up more easily.  I think because the boat is narrower, and the keel is longer, so has more leverage despite a distinctly lighter keel.
I have seen a photo of a capsized K1, all I can say is that it is reluctant to stay that way.

I’ve seen K1s capsized on at least 2 occasions and required some additional weight on the ‘keel’ to right it
