i found the course to be well presented and very appropriate. the one "negative" comment i have has nothing to do with the course as such but rather to do with the rules governing lateral system navigation or more precisely the system of colours of buoys and their placement in channels.It can be somewhat confusing to learn that one must turn to starboard when encountering another vessel in a head on approach (keeping his red light to the port side)....and then having to rethink and turn left or to port when encountering a red buoy in a channel keeping the starboard side to the red buoy....i think that someone should of thought of that in the beginning when establishing the rules....of course this is only my opinion but as the late great Chet Atkins once said "its only my opinion....and it ought to be yours".
