Canadian Boating Practice Exam

When proceeding upstream, Port-hand day beacons must be kept on the left side of the pleasure craft. This is because Port-hand day beacons are used to mark the left side or "port" side of a navigable channel when traveling upstream. Therefore, keeping them on the right side (option A) would place the pleasure craft in the incorrect side of the channel. Directly in front (option C) and directly behind (option D) are not relevant to the placement of these beacons and would not be correct choices. Keeping them on the left side (option B) allows for safe navigation and staying within the designated channel while traveling upstream.
