When each vessel sailing with the wind on different page, it should vessels with wind on the port, keep clear of the others.

(Ii)
When both vessels have the wind on the same side, it should vessels to windward, keeping clear of what is laughing.

(Iii)

If a vessel sailing with the wind on the port side sees a vessel to windward and not determine with certainty whether the other vessel has the wind on the port or starboard, shall keep clear of the others.

(B)
Under this Rule the windward is considered to be the opposite side of the mainsail as standing on, or where it applies a squarely rigged vessel, the opposite side from the one that it's staysail or spanker stands.

Rule 13. Obtaining

Rule 17. Vessels shall maintain course and speed

(A)

(I)
When either of two vessels to keep clear, should the other vessel keep its course and speed.

(Ii)
The vessel shall maintain its course and speed, however even take precautions at their maneuver to avoid collision as soon as it becomes aware that the vessel is obligated to keep clear does not take the necessary measures in accordance with these rules.

(B)
When the vessel is to maintain its course and speed for some reason has come so close to the other vessel that collisions can not be avoided by measures alone from the side of the vessel that would keep clear shall also the second vessel take such measures that will best help to avert collisions.

(C)
A power-driven vessel under paragraph (a) ii of this regulation takes precautions to avoid collision with another power-driven vessel when the two vessels manages courses that intersect should, if circumstances permit , not alter course to port for a vessel on its port side.
