Re: Close quarter maneuvering in a swift current
I have a 45 footer and my neighbors a 42 foot trimaran with a 20 foot beam. In a space barely big enough to to turn around with one boat in. We always use the spring lines to maneuver out. We tie one opposite side of the stern. Go ahead with a hard over rudder. The boat spins around in its own length. All nice and easy. When the bow clears 180 degrees from start. We let the line go and we are off.
I learned this from being on a submarine that sometimes didn't have the best port support. Old man would hang a hurricane line off the back end go forward with a strain and let it rubber band around. full stop long enough(about 15 seconds) to retrieve the line with out fouling the screw and then go.
That always carried over to everything else. He never let his last line over until he or the tug had control of the boat.
