In total agreement with Moby Duck!! Cup glued, boat turning and barrel in same position over the the eyelet below...only the shadow moves and the wake changes inward toward the hull, plus the barrel only appears to rise on the horizon because of the boat turning. Call 1-800-Bad-Juju to report fake news...or just use a google AI to generate fake videos.

Whelp that changes things a bit for sure, maybe...

It appears the gun does rotate ≈180° and that it does look like a stabilized gun as well that the boat was in a long turn. I'm still having a hard time with the cup not falling even though the sea is relatively calm, but wind and spray and the 180° rotation over a 1 minute interval with an arc of perhaps 40' would not dump that cup sitting there half full and Off Level.

As an adjunct to my link above on AI fakes, this showed up today, although a couple of days old and considering the source who's knows but I like the guys demeanor.

Being that I was Army I wasn't aboard very many ships But I was detailed to travel from Germany to Sydney For prisoner escort in 75 to bring back a couple guys who had stayed there after their leave was over from Vietnam in 1969 To get there and back it was available military only. which wound up being several various sized Naval vessels and a couple of C 130 s. On the trip down the 3 of us learned real quick how not to get rolling sickness. Like Marv said when on deck if possible get somewhere where you don't see other objects if possible especially anything that was moving about the ship in a back forth motion. I found that after a couple of days I had gained my sea legs pretty well. Moderately rough seas didn't bother me near as much as the calmer times.

The right hand one boat is much more exposed to waves.. also it sheltered the stabilized one..! not good for comparison...??!!

makes a huge difference.

Seasickness is one element of sailing I never had. Whale boat, landing craft, frigate...even carriers. Now you might think 'carrier?', but they're huge! Yep they are. But way smaller in the South China Sea, green water breaking over the bow in real storms. Two occasions; first after being aboard just a few weeks. Guys up-chucking all over the place. I was loving it, felt like dirt biking. Got a nickname, that I still hear once in awhile, 40ish years later; this guy.

living hear at the beach with lotsa boats around & even more partys & drunks on them that glass on the barrel isant impressive, Ive seen drunks do a better job of not spilling a drip in real rough seas...no gyro required, just dont give them a drink on land or it will be on you..... these days there is almost a solution for everything...almost.

Neat idea. I hope you can turn that thing off and lock it down when installed in a well designed boat that has to respond to unusual sea conditions. Read about the survival of the 49ft. lobster boat Sea Fever and most of its crew in an Atlantic storm. Wooden Boat Magazine no.264, pg 90 (current issue). I would urge the makers of the device to explore such issues and offer appropriate guidelines for when and when not to turn it on.
