PART 2


For the same reason, if contact does occur between same-tack boats that had previously not been overlapped, it may not matter whether the contact was bow to transom (i.e., with a boat clear ahead) or bow to port or starboard quarter (i.e., just after an overlap has begun from clear astern) if the protest committee is satisfied that the moment of not keeping clear (as opposed to the moment of contact) was while one of them was still clear astern.


If an Iris clear astern is sailing a course to pass to leeward of a Daffodil clear ahead on the same tack, Daffodil breaks no rule if she bears away below a proper course to frustrate this, provided that, as required by rule 16.1, Daffodil gives Iris room to keep clear. However, if in bearing away Daffodil creates a temporary overlap and becomes a windward boat under rule 11, Daffodil has no protection under rule 15, because she gave up her right of way because of her own action.


The simplicity of rule 12 in action is reflected in a paucity of published cases related to this rule alone. WS 77 referred to above, as concerns equipment that unexpectedly flies free, can be contrasted with WS 91, where there was, after a leeward mark rounding, contact between a boat clear astern and the spinnaker of the boat ahead that had been flying astern for several seconds from the top of the mast. In this case, it was found that a boat required to keep clear must keep clear of another boat’s equipment out of position when the equipment has been out of its normal position long enough for the equipment to have been seen.


Rule 10 is more complex than rule 12 in operation, since it can apply to boats that are approaching each other more rapidly.


Rule 10 Relationships


Each Red boat is on port tack and must keep clear of a nearby Green starboard-tack boat under rule 10.
