  1. In short yes, it is considered. I think key to understand that video of cavitation tunnel is that pressure is not constant there. Typically tests are run so that first you start water flow and then start to reduce the pressure. To me it would appear that towards that film they are already bringing pressure up. As to controlling the water and air in water below link to section view of a cavitation tunnel may give some hints what goes on there: https://www.researchgate.net/figure/Cavitation-tunnel-layout_fig4_234168500 Cavitation research is quite complex problem and even different test facilities have different techniques and details that they control. Some are much more coarse and others control in very fine detail.. The actual tunnel in video is Marintek (Sintef) tunnel in Trondheim Norway.

    Cruise ship making - timelapse

    Have been in past involved a bit with big cruise ships. Building process is very overlapped with design and then cruise companies do change their heart during the process. This is one of the biggest reasons why there are only handful of yards that build these large cruise vessels - you really need to accept that there is no clear plans when you start.

    Seascape 18

    Absolutely no issues with boat. I have now 7th summer and boat would be in perfect condition save for some user induced minor things. In my view checks all your specified targets. Really easy to lauch and very fun to sail. Have mostly done DH and SH. There have been couple gear upgrades over the years and in my view new outhaul setup is better (in process of changing that on my boat). Also jib tracks are better in changing conditions vs. just having multiple clew holes. Both of these really simple things to fix on your own.
