Rule 28.1, Sailing the Course

Interpretations of rule 28.1, the 'string rule'.

Summary of the Facts
The first leg of a race on the Panama River was to windward, in a weak and fluky wind and against a strong current. Boats A and B started correctly, but the wind died and they drifted backwards. A passed outside the port end of the line, and B crossed back over the line. Later, the wind returned but from a new direction, and both boats passed to starboard of the race committee boat at the starboard end of the line and continued up the leg. A protested B for breaking the ‘string rule’ (rule 28.1) but the protest committee decided that the protest was invalid. However, it sent the protest to the national authority under rule 70.3.

 

Decision
Boat A complied with rule 28.1. After starting, she left each starting mark on its required side. Then she sailed around the entire starting line as shown. Even so, the string representing her wake, when drawn taut, leaves each starting mark on the required side as it crosses the starting line. Rule 28.1 does not prohibit extra turns around a mark, provided that the string when drawn taut lies on the required side of each mark. For example, if a boat touches a rounding mark while leaving it on her starboard side as required by the sailing instructions, and then does a clockwise penalty turn around it, she complies with rule 28.1. Another example, as boat A illustrates in this case, is when a boat’s string passes a mark (in this case, the race committee boat) on the required side, she does not break rule 28.1 when her string also passes that mark on the non-required side. Boat B broke rule 28.1. After starting, she left the port-end mark to port and the starboard-end mark to starboard, as required. However, she later drifted back across the starting line and then left the starboard-end mark to port. When the string representing her wake is drawn taught it will not pass through the starting line and therefore will not leave the starboard-end mark on the required side.
