Mostly OK, but noticed several factual errors: 1) The blood alcohol concentration limit is incorrectly reported in units of milligrams (mg). This is not a unit of alcohol concentration in blood. If you say 5 mg per liter of blood, or 5 %, or 5 parts per billion, these are units of concentration, but 5 mg is not. 2) If the module that discusses recommended boat speeds, the audio narrative refers to a distance of 1.6 km as a nautical mile, but this is a land mile, not a nautical mile, which is 1.85 km. The audio text and the visuals are in disagreement. 3) The module on navigation aids shows a diagram illustrating different types of signs that may be posted on shorelines. One of those is identified as standardized speed limit sign, but in the figure, the sign shown is a sign for engine power limit (Max kW),not speed limit (Max km/h). Also, the emergency module should show the best techniques for safely hauling a person back on board a small craft, such as boat with low gunwales, or an inflatable boat. Right now this is missing from the course, and it is particularly crucial to know this.
