(pillow)Case of the week (12/12) – 17

(This is an instalment in a series of blogposts about the ISAF Case book 2009-2012 with amendments for 2010. All cases are official interpretations by the ISAF committees on how the Racing Rules of Sailing should be used or interpreted. The cases are copied from the Casebook, only the comments are written by me.)

(This weeks case is number 17, because Case 18 is deleted in the Casebook)

CASE 17

Rule 13, While Tacking

A boat is no longer subject to rule 13 when she is on a close-hauled course, regardless of her movement through the water or the sheeting of her sails.

Question

Rule 13 applies until the tacking boat ‘is on a close-hauled course.’ However, the rule does not say whether the boat must be moving when she assumes a close-hauled course. Is it intended that, at the moment rule 13 ceases to apply, the boat must actually be moving through the water on a close-hauled course and not merely be on such a course?

Answer

A boat is no longer subject to rule 13 when she is on a close-hauled course, regardless of her movement through the water or the sheeting of her sails.

Which makes it harder to see, sometimes. But that’s the way the rule is written and HAS to be used.
I always tell sailors who have a hard time recognizing if a boat has turned from head to wind enough, to use their own boat as reference. As most racing is done in one design classes, that should give them enough to work with.

Skutsje

In the Netherlands we race with ‘traditional’ boats who are equipped with leeboards. Those have a very big angle towards the wind, when sailing close hauled. Nevertheless the moment rule 13 switches off comes sooner than most sailors think. Err on the side of caution is a prudent strategy.

  1. Is it April first already? Don't want to be on that protest committee. Will miss dinner and then some.
