Not entirely true

If you are a power boat and the other boat is a sailboat undersail, you must give way.

There are a few exceptions:

vessels not in command (i.e. not under control);

where it is too difficult for a large power boat to navigate in a small channel;

where the powered vessel, due to its size, has difficulty in navigating at the best of time;

vessels engaged in fishing.

As a general principle, stay well clear of large powered vessels; they have difficulty in maneuvering, they may not see you and you could capsize in the wash.
