    It is not like they did a barrel roll around the Russian ship!

    Looks like what a navy classmate of mine calls "shouldering." As described to me, when a carrier group is being shadowed and then the "shadower" moves in too closely, a destroyer from the screen will move out to "shoulder" the shadower and to "convince them" to alter course. The intruder can NOT be allowed to enter within the battle groups' screen.

    Again, that's how it was explained to me, the AF pilot guy.

    Every time I've seen shouldering it involves physical contact between the boats or ships.

    Look up USS Caron and USS Yorktown in the Black Sea video from 1988. Now that is shouldering.

    I think that one is a prime example in "interaction", when the boats get sucked together because of the relatively faster moving water between the hulls.

    Same thing happens with one semi passing another. Bernoulli?

    Yep. Bernoulli is well-documented during underway replenishment (UNREP) evolutions, and must be accounted for by careful maneuvering of both ships. Especially fun with ships taking fuel on each side of an oiler. Matching speed and separation alignment are key. Approach and detach can be particularly challenging. Emergency breakaways are part of the skill set. UNREP is different than shouldering, but the same physics apply.

    Well, like I said...I'm a pilot; Bernoulli (and its issues with air refueling) I understand well, ships at sea...not so much. Going to have to ask my classmate why he left out the "contact" part about shouldering though...

    Yowee. I hadn't seen that in a while.

    No Bernoulli Principle there.
