DEFINITIONSA term used as stated below is shown in italic type or, in preambles, in bolditalic type.

Abandon A race that a race committee or protest committee abandons isvoid but may be resailed.

Clear Astern and Clear Ahead; Overlap One boat is clear astern of another when her hull and equipment in normal position are behind a line abeam from the aftermost point of the other boat’s hull and equipment in normal position. The other boat is clear ahead. They overlap when neither is clear astern. However, they also overlap when a boat between them overlaps both. These terms always apply to boats on the same tack. They do not apply to boats on opposite tacks unless rule 18 applies or both boats are sailing more than ninety degrees from the true wind.

Fetching A boat is fetching a mark when she is in a position to pass to windward of it and leave it on the required side without changing tack.

Finish A boat finishes when any part of her hull, or crew or equipment in normal position, crosses the finishing line in the direction of the course from the last mark, either for the first time or after taking a penalty under rule 44.2 or, after correcting an error made at the finishing line, under rule 28.1.

Interested Party A person who may gain or lose as a result of a protestcommittee’s decision, or who has a close personal interest in the decision.

Keep Clear One boat keeps clear of another if the other can sail her coursewith no need to take avoiding action and, when the boats are overlapped onthe same tack, if the leeward boat can change course in both directionswithout immediately making contact with the windward boat.

Leeward and Windward A boat’s leeward side is the side that is or, whenshe is head to wind, was away from the wind. However, when sailing by thelee or directly downwind, her leeward side is the side on which her mainsaillies. The other side is her windward side. When two boats on the same tackoverlap, the one on the leeward side of the other is the leeward boat. Theother is the windward boat.

Mark An object the sailing instructions require a boat to leave on a specifiedside, and a race committee boat surrounded by navigable water from which the starting or finishing line extends. An anchor line or an object attached temporarily or accidentally to a mark is not part of it.

Mark-Room Room for a boat to sail to the mark, and then room to sail herproper course while at the mark. However, mark-room does not includeroom to tack unless the boat is overlapped to windward and on the inside ofthe boat required to give mark-room.

Obstruction An object that a boat could not pass without changing coursesubstantially, if she were sailing directly towards it and one of her hulllengths from it. An object that can be safely passed on only one side and anarea so designated by the sailing instructions are also obstructions. However,a boat racing is not an obstruction to other boats unless they are required to keep clear of her, give her room or mark-room or, if rule 22 applies, avoidher. A vessel under way, including a boat racing, is never a continuingobstruction.

Overlap See Clear Astern and Clear Ahead; Overlap.

Party A party to a hearing: a protestor; a protestee; a boat requestingredress; a boat or a competitor that may be penalized under rule 69.1; a racecommittee or an organizing authority in a hearing under rule 62.1(a).

Postpone A postponed race is delayed before its scheduled start but may bestarted or abandoned later.

Proper Course A course a boat would sail to finish as soon as possible inthe absence of the other boats referred to in the rule using the term. A boathas no proper course before her starting signal.

Protest An allegation made under rule 61.2 by a boat, a race committee or aprotest committee that a boat has broken a rule.

Racing A boat is racing from her preparatory signal until she finishes andclears the finishing line and marks or retires, or until the race committeesignals a general recall, postponement or abandonment.

Room The space a boat needs in the existing conditions while manoeuvringpromptly in a seamanlike way.

Start A boat starts when, having been entirely on the pre-start side of thestarting line at or after her starting signal, and having complied with rule 30.1if it applies, any part of her hull, crew or equipment crosses the starting linein the direction of the first mark.

Tack, Starboard or Port A boat is on the tack, starboard or port, correspondingto her windward side.

Zone The area around a mark within a distance of three hull lengths of theboat nearer to it. A boat is in the zone when any part of her hull is in the zone.

Windward See Leeward and Windward.

Rule (a) The rules in this book, including the Definitions, Race Signals,Introduction, preambles and the rules of relevant appendices,but not titles;DEFINITIONS153(b) ISAF Regulation 19, Eligibility Code; Regulation 20, Advertis- ing Code; Regulation 21, Anti-Doping Code; and Regulation22, Sailor Classification Code;(c) the prescriptions of the national authority, unless they arechanged by the sailing instructions in compliance with thenational authority’s prescription, if any, to rule 88;(d) the class rules (for a boat racing under a handicap or ratingsystem, the rules of that system are ‘class rules’);(e) the notice of race;(f) the sailing instructions; and(g) any other documents that govern the event.

Luffing -

When?, Where?, & How Far?

Bob Harvey

Rule 17 – On the same tack; Proper Course

Definitions

Tack – A boat is on the tack (starboard or port) corresponding to her windward side.

Proper Course – A course a boat would sail to finish as soon as possible in the absence of the other boats referred to in the rule using the term. A boat has no proper course before her starting signal. (Note that this doesn’t say in the absence of other boats, just those mentioned in a specific rule).

Bob’s definition of luffing – Sailing above close hauled up to dead into the wind … any further you’d be tacking and Rule 13 would take over.

A boat may luff head to wind anytime during the race when not forbidden from doing so by a specific rule. She has the right to do so an is only constrained by the requirement to give room (not time) to keep clear [Rule 16], and an onus to avoid contact [Rule 14].

So, when can’t a boat luff? Rule 17 says …

If a boat clear astern becomes overlapped within two of her hull lengths to leeward of a boat on the same tack, she shall not sail above her proper course while they remain on the same tack and overlapped within that distance, unless in doing so she sails promptly astern of the other boat. This rule does not apply if the overlap begins while the windward boat is required by Rule 13 to keep clear.

Wow! …….. Where the heck does that leave us?

We know proper course can vary a bit from boat to boat upwind, say as much as ten degrees, but there’s little doubt upwind that leeward boat, while burdened by Rule 17, can’t luff (sail above close hauled) because that wouldn’t be her proper course.

Downwind is a LOT more interesting! Proper course varies all over the place for different boat types in varying wind speeds (Discuss!!). The leeward boat still can’t sail above her proper course while burdened by Rule 17, but that could be considerably higher than the windward boat wants to sail.

Let’s remember that Rule 17 only puts a burden on the leeward boat, it does not convey a right to the windward boat. Windward doesn’t have any right to sail her proper course! Leeward simply can’t sail above hers.

Let’s also remember that Rule 17 only applies when the overlap is ESTABLISHED within two of leeward’s hull lengths … if the overlap existed prior to the two hull length separation, leeward isn’t burdened by Rule 17 and can head as high as they like.

• Weight Savings• Stretch Resistance• Increased Strength

Puff in 3…2…1….

Now what?

Loads increase on rigging causing lines to stretch.

You Make The Call

You are rounding the weather mark and your keel snags the anchor rode and pulls the mark into your boat.

1.There is a foul & so you should re-round the mark.

2.There is a foul so you should sail clear & do one turn & one gybe and continue the race.

3.There was no foul because you hit the anchor rode, which is not part of the mark; hence no foul.

You Make The Call

You are finishing in light air and your bow crosses the finish line and are acknowledged by the race committee. Before you clear the finish line you touch the leeward mark.

1.You ignore the touch because you have all ready been finished2.You circle around the mark , Gybe and then recross the Finish line3.You clear the line, do one gybe and one tack and recross the finish line from the direction of the last mark

You Make The Call

In reviewing the posted score you find that the boat that finished behind you is scored ahead.

1.Later in the bar, demand the race committee change the scoring.2.Storm out of the club vowing never to race again.3.Ask for a scoring review. Provide your finish time, and the number of the boat that finish ahead of you and the number of the boat that finished after you [ which you always record] . Bring another competitor as a witness.
