OTHER RULES
When rule 22 or 23 applies between two boats, Section A rules do not.

  2. she is compelled to break rule 31.

A boat taking a penalty shall keep clear of one that is not.

If possible, a boat shall avoid a boat that is capsized or has not regained control after capsizing, is anchored or aground, or is trying to help a person or vessel in danger.  A boat is capsized when her masthead is in the water.
