You're a treasure and we hope to have for for 84 more years!
That shot of 995 was very angular, perhaps a new word is needed to be accurate: it's not really canning in that shot, but does show ribs...maybe: "ribbing"
Something to show it's not a plastic hull.
I imagine surface ships, especially that frigate with the V, would get a a lot of wave slapping, too.
Thanks for the pix and the discussion starter!
