As a landlubber, I don’t know the rules of the sea, but does state law not apply once you are afloat? This seem like Reckless Endangerment or something similar. Will she get a pass based on her status as an eccentric rich lady? I hope not.
There are lots of State laws one could break lots of different ways, but for the situation as we know it (incompletely) the vessel that has the technical right of way the boat wins. If the harbor is too tight, congested, or unsafe the plane has no right to be there and it might very well be an argument they should shut up about.
Like Maryland's AG pushing the limits of abortion, they should have known what might happen.
It seems that you are being obtuse. Perhaps you have a stake in this? I don’t. The video shows the boat closely circling the plane several times. This was no simple right of way issue. Not even close.
