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...
Analysis of tracking data from Automatic Identification System broadcasts reveals vessel locations have been simulated for a number of ships, including military vessels. This false information could compromise vessel safety, decrease confidence in a crucial collision avoidance system and potentially spark international conflict.
Research on hydrodynamic interaction indicates that if the speed of the ship near a bank is too high, the rudder may be less able to cope with the forces induced and control will be lost. The Nautical Institute highlights this in its latest Mars Report, in which an LPG carrier hit a barge being towed by a tugboat as a result of hydrodynamic forces.
This video explains the impact of lateral resistance on the turning circle of a vessel using animations. The video explains the term lateral resistance, shows an example of its impact on the turning circle and its associated aspects (advance, transfer, tactical diameter and drift angle).
Contents of this video will benefit mariners preparing for exams (written and oral examinations).
