Rules of the Road
Rule 9-Steering & Sailing Rules
International/Inland
(b) A vessel of less than 20 meters in length or a sailing vessel shall not impede the passage of a vessel that can safely navigate only within a narrow channel or fairway.
***This applies to sailing vessels that are tacking in a channel or fairway.
Rule 18
Steering and Sailing Rules.
Responsibilities Between Vessels.
Except where Rules 9,10 and 13 otherwise require:
(a) A power driven vessel underway shall keep out of the way of:
(iv) a sailing vessel.
(b) A sailing vessel underway shall keep out of the way :
(i) a vessel not under command
(ii) a vessel restricted in her ability to maneuver .
The sailboat operator is the stand-on vessel so they should keep their course and speed while the PWC is the give-away vessel so it should change course and speed.
The powerboat should pass to the stern of the sailboat to avoid its wash causing a problem for the sailboat To avoid a collision, the powerboat should avoid crossing ahead of the sailboat.
You should give way to starboard.
The power-driven vessel should change course and speed.
Maintain present course and speed.
When there is a danger of collision, the "stand-on" vessel is the one that must maintain its course while the other must take avoiding action. Sailboats usually are the stand-on vessel when meeting a power-driven vessel, even if that vessel is another sailboat (if its engine is powering the boat, and regardless of whether its sails are raised or not). There are exceptions: if the power-driven vessel is "working," such as a fishing boat dragging nets, or the power-driven vessel is confined to a narrow channel due to its draft, then the sailboat must stay out of the way, by altering course if necessary. If a collision is imminent and the other vessel shows no signs of altering course, then the sailboat should take whatever course is necessary to avoid it.
If you are operating a motorboat and your motorboat is being overtaken by a sailboat, you should maintain present course and speed. The vessel that is overtaking another vessel is the give-way vessel, regardless of whether it is a sailing vessel or a power-driven vessel. The vessel being overtaken is always the stand-on vessel.
Starboard ( right side ) and it should be mounted so it is visible at 135 degrees .
The power driven vessel should give way to the sailing vessel in most cases. The action taken shall be taken in good time, be obvious and seamanlike and should result in the give way vessel passing at a safe distance.
Speed up to pass in front of the sailboat
Do whatever is necessary to stay clear of the sailboat.
The question should be "What is aft on a sailboat?" since it is a direction, not a thing. Aft (or after) is anything toward the rear of the boat.
