We have seen some unusual Coast Guard boats. The hovercraft passed us doing 20 knots. That’s about 40 km per hour. Later that day we actually met that same craft in Sorel and were invited aboard. The captain was able to give me the latest weather and other information. He told me top speed of the hovercraft was 50 knots, being about 100 km under ideal conditions.
The next boat we met on the river was a research vessel doing bottom measurements.
