“The first is of some of the small boats. Many have a "skirt"(?). Is this to reduce the chance of a wave catching them from astern?”
I think it would increase that chance. A significant stern sea would tend to hold dowd the stern so a wave could come aboard and poop the stern putting them in a very bad way. Perhaps the word “floundering” would apply. Seen quite a few pics of boats w “skirts” and I’m sure it’s an attempt to make a FD boat go faster. One from Spain has been marketed in the US.
Sometimes we really do get “interesting” boats .. thanks.
Me-thinks it would act something like a wave piercing bow, in that the stern would get some early lift and some of the waves energy would spill off to either side of the stern, instead of all the energy hitting the stern square on.
Don't think them Icelandic guys would put a 'skirt' on their boat just to be fashionable.

We talked about her sister ship in the spring post 4119. She didn't have a mast. There were 8 built as I recall. Another one was for sale this summer. Really like the look of them. Except no place to land a salmon.
ABout 20 years ago they were being pushed on the east coast . Never saw one but lots of photos and write ups.. That bustle was a modification to the original hulls to get more speed from their mostly displacement hulls for fishing and commercial use.
It apparently did work. From the articles it also improved seakeeping.
In the pleasure boat market that bustle got expanded, a lot.
Then an economic downturn occurred and I never heard of them again untill now.
The bustle for commercial was much smaller than the pleasure boat versions.
