(Tyboo, somehow I ended up on this one:
https://youtu.be/_weLIMK4ImE ... a Lisbon pilot transfer. Wrong one.)
That is a very dicey move compared to what your son's video shows. The pilot in the correct video makes a swift, clean transfer, still a ballsy move, though! Thanks for putting it up.
[Aside: Fifteen years ago I watched a Columbia River Bar pilot, Deb Dempsey, do a similar move onto a car carrier one night when Becky and I were guests aboard the Chinook (pilot launch). It was smooth and uneventful, with only a short reach and step for her.
Columbia River Bar pilots and their pilot boat crews typically arrange things so the pilot can use the sheltered side of the freighter when both vessels are running parallel at about 8 to 10 knots, just like in the correct video! That arrangement makes for a relatively protected transfer. Specifically, there is very little clapotis, aka rebounding wave action.
That said, the CRB Pilots lost a pilot, fairly new to the game, a few years back when he fell between the vessels and suffered a head injury as the pilot launch came down on him ... suggesting clapotis is not entirely absent in CRB Pilot transfers.]
