Under the IALA Region B 'Red Right Returning' rule, what does a skipper do with red lateral buoys when entering a Chilean port or bay from open sea?

1. Keep all red buoys on the starboard (right) side of the vessel
2. Keep all red buoys on the port (left) side of the vessel
3. Pass directly over the red buoys at maximum speed
4. Steer halfway between two red buoys on the same line
