However, I'll never throw them the bow line. Most of the time the unknown help will get the line attached to the mid-cleat. That way, they can't pull it in too tight and cause the stern to swing out from the dock!
Everybody always wants to pull the damn bow in.
Thats the skinny part of the boat, pull in the fat part.
I have to tell any newcomer trying to help.
Bow Out, Stern In.
It never works, they always grab the bow and pull as hard as they can.
I much prefer docking with just my wife and me on our slip.
The dock lines are already attached to the finger pier. I pull in, she grabs the spring with a boat hook, and I use prop walk to settle the stern.
Still get a little nervous when every anybody is watching, but everybody in our Marina is usually very helpful. We all help each other, especially on windy days.
