COLREGS, Rule 9, Narrow Channels, (b) A vessel of less than 20 meters in length or a sailing vessel shall not impede the passage of a vessel which can safely navigate only within a narrow channel or fairway.

The CG was correct if a bit rude.

Depending on how far out, you might've still been under the inland rules.

Not that my pedantry changes anything - sailboat still comes below "vessel restricted in its ability to maneuver" and you gotta give way all the same.
