In looking at all the Moth photos, it appears that some of them have wings that are just bare pipes, some have sort of solid trampolines, and some have open netting, and some a combination of the two. I am wondering what the advantages and disadvantages are of each. And whether those advantages/disadvantages are different depending on whether it is an on-water boat or hydrofoil boat.

I'm sure this information could also be applied somehow to multihulls.
