I was so frustrated the first 1/2 dozen or so times my first season with my docking technique I really started questioning my ability to control my boat.
Then I was shown how to install a bridle system to keep my boat in the slip while docking and departing, no matter what the wind.
The bridle guides the boat in and if needed I can pick up one of the bridle lines and pull the boat in.
The fender on the bridle keeps me from hitting the dock if coming in too hot and the lines keep me from drifting into my neighbors boat.
That and learning to use a spring line to hold the boat against the finger pier has let me solo dock even when I have others on the boat.
As for extra controls on the OB, I steer with my rudder, leaving the OB straight. I only control the shifter and most times leave it at idle. I dock into the prevailing wind which does help.
Attached is a drawing of the bridle set up in my slip and a photo of the front of the bridle.
As other posters have said, "Never go faster than your willing to hit your dock"
