Located at the Superior Entry to the Duluth-Superior Harbor, the Wisconsin Point Cam is perfectly located to catch the large and small craft as they move through the Canal.
This camera is made possible with help from the Lake Superior Maritime Visitor Center, and the many viewers who so generously support these cameras.
Operational Notes:
Once the bow of the boat enters the canal, the camera signal will be lost until the boat is passed by the camera, then it will turn back on. This is due...
The Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.
This my attempt to do just that. This is a summary of all scientific papers and articles that I could find about the ship’s pivot point. I have added links to any videos associated with the publications and have also included any useful diagrams or equations that the authors published to help explain their research.
Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal should be conducted: come in close to the stern and then move away from the bow that will be sucked towards your...
