Going by the Rules - We're racing

  1. 1. Start Section Start show We’re racing!We‟re racing! Main Menu Section Start 1

Kerrunch!Let‟s invent a rule: “Every boat shall avoid contact with every other boat”.Perhaps that’s not going to work…so we need some better rules. Main Menu Section Start 6
  7. 7. Start Section Start show We’re racing!Safety when two boats meet• One of them must keep clear• The other has right of way, but her freedom to manoeuvre is restricted• But if the keep-clear boat does not avoid contact, the right-of-way boat must try to do so• Applies to both • the Racing Rules of Sailing (RRS) and … • the International Regulations for Preventing Collisions at Sea (IRPCAS) Main Menu Section Start 7
  8. 8. Start Section Start show We’re racing!When boats meet – it has to be easy for both to know which onemust keep clear. Just three criteria:1. Which tack is each boat on?2. Are they on the same tack or on opposite tacks?3. Are they overlapped? Italics mean a define d word or term Main Menu Section Start 8
  9. 9. Start Section Start show We’re racing!How do you decide which tack a boat is on?Tack is a defined termTack, Starboard or PortA boat is on the tack, starboard or port, corresponding to herwindward side.Leeward and WindwardA boat‟s leeward side is the side that is or, when she is head towind, was away from the wind. However, when sailing by the leeor directly downwind, her leeward side is the side on which hermainsail lies. The other side is her windward side… Main Menu Section Start 9

The otherboat is clear ahead.Equipment that is NOT in its normal position cannot create anoverlap. For example:• a spinnaker allowed to fly forwards by freeing its halyard• a retractable „sprit‟ that is extended when there is no immediateintention of setting a gennakerIf a boat astern with such equipment in an abnormal position iscatching the boat ahead, then:• No overlap until the first piece of hull, or equipment in normalposition (such as the spinnaker pole) crosses the transom line• and so ( in the case of the spinnaker) the overlap will happen laterthan if the equipment had been in its normal position Main Menu Section Start 51

No – so neither is clear astern, so they are overlappedEach pair is on the same tack, and the term overlap „alwaysapplies to boats on the same tack.‟ (Definition Overlap) Main Menu Section Start 58
  59. 59. Start show We’re racing! Definition, Clear Astern and Clear Ahead; OverlapAre Yellow and Blue overlapped?No. The term does not apply to opposite tack boats sailing towindward and away from marks Main Menu Section Start 59

  61. 61. Start show We’re racing! Definition, Clear Astern and Clear Ahead; OverlapAre Yellow and Blue overlapped?Technically YES, because the definition Overlap says that the termapplies to boats sailing more than ninety degrees from the wind.However, in open water, this fact has no further significance in therules. BLUE on port must keep clear of YELLOW on starboard. Main Menu Section Start 61
  62. 62. Start show We’re racing! Definition, Clear Astern and Clear Ahead; OverlapAre Yellow and Blue overlapped? Main Menu Section Start 62
  63. 63. Start show We’re racing! Definition, Clear Astern and Clear Ahead; OverlapAre Yellow and Blue overlapped? Yes, even though they are on opposite tacks, both because rule 18, Mark- Room, applies, and also because they are both sailing more than ninety degrees from the true wind. In this case, BLUE on port still has to keep clear of YELLOW on starboard, but rule 18 puts a limitation on YELLOW, which will have to give mark-room. Main Menu Section Start 63
  64. 64. Start show We’re racing! Definition, Clear Astern and Clear Ahead; OverlapIs Blue clear ahead of Yellow?IS Yellow clear astern of Blue?The terms Clear Astern and ClearAhead do not apply to boats onopposite tacks away from marksand obstructions.This situation is resolved by rule10 that deals with opposite-tackboats, and not by rule 12 thatdeals with same-tack boats whereone is clear astern of the other. Main Menu Section Start 64
  65. 65. Start show We’re racing! Definition, Clear Astern and Clear Ahead; OverlapIs Blue clear ahead of Yellow?IS Yellow clear astern of Blue?YES. The terms Clear Astern andClear Ahead apply to opposite-tackboats when rule 18 applies, or whenboth boats are sailing more thanninety degrees from the wind.Both of these criteria make this aclear-ahead / clear-astern situation.As we will see, BLUE on port stillhas to keep clear of YELLOW onstarboard, but rule 18 requiresclear-astern YELLOW to give mark-room to clear-ahead BLUE Main Menu Section Start 65
  66. 66. Start Section Start show We’re racing! Italics mean a defined word orThree Main Rules termWhen boats are on opposite tacks, a port-tack boat shall keep clear ofa starboard-tack boat. (Rule 10)When boats are on the same tack and overlapped, a windward boatshall keep clear of a leeward boat. (Rule 11)When boats are on the same tack, and NOT overlapped, a boat clearastern shall keep clear of a boat clear ahead. (Rule 12)Keep ClearOne boat keeps clear of another if the other can sail her course withno need to take avoiding action and, when the boats are overlappedon the same tack, if the leeward boat can change course in bothdirections without immediately making contact with the windwardboat.

  71. 71. Start show We’re racing! Definition, Keep ClearIs BLUE keeping clear of YELLOW?What is the test?The test is first whether YELLOW, the right-of-way boat, can sail her coursewith no need to take avoiding action.If their courses are parallel, even if BLUE is close, YELLOW can sail hercourse.

During that time rules10, 11 and 12 do not apply. If two boats are subject to this rule atthe same time, the one on the other‟s port side or the one asternshall keep clear.„Tacking‟ is not a defined. The word in the rule title is used in itsgeneral sense of going from one tack to the other.However, the words of the rule itself apply to only a part of thisaction, from when a boat passes head to wind until she is on aclose-hauled course. Her sails need not be full at that moment.During that time, a boat shall keep clear of other boats. Theprevious three rules (10, 11, 12) don‟t apply at that time.A tacking boat is always on one tack or the other. The tack changeswhen passing head to wind. Main Menu Section Start 83

Start Section Start show We’re racing!Rule 14 - Avoiding ContactA boat shall avoid contact with another boat if reasonably possible.However, a right-of-way boat or one entitled to room or mark-room (a) need not act to avoid contact until it is clear that the other boat is not keeping clear or giving room or mark-room, and (b) shall not be penalized under this rule unless there is contact that causes damage or injury.Keeping clear is more than just avoiding contact. So this rule does notadd to the requirements of a keep-clear boatDespite the first line of the rule, it‟s safer and fairer for a right-of-wayboat to „stand on‟ until it is clear that the keep-clear boat isn‟t doing soEven if a right-of-way or room-entitled boat wrongfully allows a collisionto happen, she will be penalized only when damage or injury resultsSo a right-of-way boat or one entitled to room or mark-room can breakthe first line of this rule - at her own risk Main Menu Section Start 91
