My comments to my crew for our 2011 charter of a 47' power cat:
DO NOT attempt to fend the boat off a dock if it looks like we are going to collide with it. 22 tons of boat is only going to crush your arm/hand and nobody is going to thank you for your efforts.
We never had this problem but I'm betting that somebody else WILL sooner or later.
I give the same brief. I do however point out that if the insist on trying to save the boat hitting something their body does make an effective fender if put in place at the proper time!
On sailboats it’s also important to tell guests to never untie a line, sheet or halyard unless they have verified the line is not under load or is properly controlled. If in doubt I tell them to call me and leave it alone.
