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...
How to get information for wind & current limits to be potentially encountered by thrusters – or current? - this will be described in this movie:
- Measure Drift speed, due to beam wind with no propulsion;
- Measure drift speed using full thrusters
- Estimate wind & current limits to be potentially encountered by thrusters – or current...
- Finally there is a simple formula as Rule of Thumb: the transverse drift speed is about 7-8% of wind speed!
A handy and simple tool to determine in a minimum time what is really needed as tug assistance, is the Bollard Pull Calculator which calculates in an approximate way the total required tug power for ships in various conditions of wind and current. This tool can be loaded as an app on the smart phone.
