When two boats or personal watercraft are approaching each other "head-on" or nearly so, so as to involve risk of collision, it shall be the duty of each boat to bear to the right and pass the other boat on its left side. When boats approach each other obliquely or at right angles, the boat approaching on the right side has the right-of-way. One boat may overtake another on either side but must grant right-of-way to the overtaken boat.
