Skier's Choice Moomba Series 2019 Owner's Manual page 34

When two power-driven vessels are crossing each other's path
close enough to run the risk of collision, the vessel that views
the crossing vessel to the starboard (right) side must give-way.
If the other vessel is to the port (left) side, maintain your course
and direction, provided the other vessel gives you the right-of-
way as it should.
If you are passing another vessel, you are the give-way vessel.
This means that the other vessel is expected to maintain its
course and speed. You must stay out of its way as you clear it,
altering course and speed as necessary.
Conversely, if you are being passed by another vessel, you
should maintain your speed and direction so that the other
vessel can steer itself around you.

There are three other rules to always remember when
driving your boat around other vessels.
When navigating in narrow channels, you should keep
to the right when it is safe and practical to do so. If the
operator of a power-driven vessel is preparing to go
around a bend that may obstruct the view of other water
vessels, the operator should sound a prolonged blast on
the whistle or horn—four to six seconds.
If another vessel is around the bend, it too should sound
the whistle or horn. Even if no reply is heard, however, the
vessel should still proceed around the bend with caution.
If you navigate these type of waters, you should carry a
portable air horn, which are available from local marine
supply stores.
