Far too detailed for the basic boater. It prevents some from even attempting it, especially those with a dingy and a little electric motor that also have to have a boater's license. A suggestion would be to have "the basic know how" for every boater (eg port/starboard/green light/red light/ red buoy on right/ green buoy on left) collected together in one module. All your other modules could expand on the "skeleton basics". That way a person could concentrate completely on what applies individually to their own immediate particular circumstances and then expand to know what is expected for those with bigger boats, etc. Also the time mandated thing doesn't always coincide with the timing of the voice. The vocal is finished but the timer isn't and vise versa. Some screens would not display either. Thank you though : )
