When is a sailboat The stand on vessel in relations to recreational powerboat?

Answer 1

Generally speaking a sailboat under sail is the stand on-vessel (privileged) over a power vessel. There are important exceptions.

A sailboat cannot impede a vessel that is limited in it's ability to maneuver (examples; a tug boat with a tow, a fishing vessel with nets, etc)

A sailboat cannot impede a vessel constrained by it's draft ( that is it cannot move outside the channel because it will run aground)

A sailboat under power is consider a power vessel and must obey the same rules as all power vessels.

A sailing vessel may not impede a vessel that can only maneuver in a narrow channel or fairway.
