That is the most frightening bit. For example...
Some marinas send line handlers that can manage any botched approach. I can think of one marina that has a nasty current across the docks that must really train the hands.
Some marinas send line handlers that you are better not using at all. I've had line handlers let lines run that I clearly and specifically asked that they simply secure so that I could power against them. No trouble, but confusing until I realize the problem.
I can't see trusting unknown help. In the PO's example, they may simply not understand that your intention is to apply 2-tons of force in a few seconds and try to hand-hold, believing that is better.
