Hello Phil Pugliese,
The tender that was my last at sea duty station did a refueling evolution and a resupply. The refueling evolution required both ships to steam relatively close to each other maintaining speed, course, and separation while taking on the fuel. The resupply consisted of having the Navy's version of the Chinook helicopter fly between the supply ship and tender. In both cases they are routine evolutions, however they are still hazardous considering that the lines used to pass the fuel hoses could break and the released tension sending the ends flying.
Tying up and pulling away for a pier is routine again because the lines could fail is hazardous.
In-flight refueling is routine to many military pilots but again is also hazardous when things go wrong.
My guess is the Referee judged skimming to be similar to in-flight refueling and applied the appropriate numbers. I was trying and apparently did not succeed in doing was to show that any game action, including a miss-jump, can end a game.
