  3. Start Section Start show We’re racing! Let’s assume we’ve started. We’re getting close to another boat. If one of us doesn’t do something, we’ll collide. Section Start Main Menu

  4. Start Section Start show We’re racing! Let’s assume we’ve started. We’re getting close to another boat. If one of us doesn’t do something, we’ll collide. Let’s invent a rule: “Every boat shall avoid contact with every other boat”. Section Start Main Menu

  5. Start Section Start show We’re racing! Let’s assume we’ve started. We’re getting close to another boat. If one of us doesn’t do something, we’ll collide. Let’s invent a rule: “Every boat shall avoid contact with every other boat”. Section Start Main Menu

  6. Start Section Start show We’re racing! Let’s assume we’ve started. We’re getting close to another boat. If one of us doesn’t do something, we’ll collide. 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. Section Start Main Menu

  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) Section Start Main Menu

  8. Start Section Start show We’re racing! When boats meet– it has to be easy for both to know which one must keep clear. Just three criteria: • Which tack is each boat on? • Are they on the same tack or on opposite tacks? • Are they overlapped? Italics mean a defined word or term Section Start Main Menu

  9. Start Section Start show We’re racing! How do you decide which tack a boat is on? Tack is a defined term Tack, Starboard or Port A boat is on the tack, starboard or port, corresponding to her windward side. Leeward and Windward A boat’s leeward side is the side that is or, when she is head to wind, was away from the wind. However, when sailing by the lee or directly downwind, her leeward side is the side on which her mainsail lies. The other side is her windward side… Section Start Main Menu

  37. Start Section Start show We’re racing! When boats meet – it has to be easy for both to know which one must keep clear. Just three criteria:1. Which tack is each boat on? • Are they on the same tack or on opposite tacks? • Are they overlapped? 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 unlesss rule 18 applies or both boats are sailing more than ninety degrees from the true wind. Section Start Main Menu

  38. Start show We’re racing! Definition, Clear Astern and Clear Ahead; Overlap Is one of these same-tack boats clear astern of the other? Section Start Main Menu

  39. Start show We’re racing! Definition, Clear Astern and Clear Ahead; Overlap Is one of these same-tack boats clear astern of the other? YES – All of Blue is behind Yellow’s ‘transom line. So they are not overlapped Section Start Main Menu

  40. Start show We’re racing! Definition, Clear Astern and Clear Ahead; Overlap Is one of these same-tack boats still clear astern of the other? Section Start Main Menu

  41. Start show We’re racing! Definition, Clear Astern and Clear Ahead; Overlap Is one of these same-tack boats still clear astern of the other? No, some of Blue is ahead of Yellow’s ‘transom line’. So they are overlapped. Section Start Main Menu

  42. Start show We’re racing! Definition, Clear Astern and Clear Ahead; Overlap Is one of these same-tack boats still clear astern of the other? No, some of Blue is ahead of Yellow’s ‘transom line’. So they are overlapped. Technically, a line abeam from the aftermost point of hull AND equipment, which would include a transom-mounted rudder. Section Start Main Menu

  43. Start show We’re racing! Definition, Clear Astern and Clear Ahead; Overlap Is one of these same-tack boats clear astern of the other? Section Start Main Menu

  44. Start show We’re racing! Definition, Clear Astern and Clear Ahead; Overlap Is one of these same-tack boats clear astern of the other? No, some of Yellow is ahead of Blue’s ‘transom line’. So they are still overlapped. Section Start Main Menu

  46. Start show We’re racing! Definition, Clear Astern and Clear Ahead; Overlap Is one of these same-tack boats clear astern of the other? Yes, all of Yellow is now clear astern of Blue’s ‘transom line’. The overlap has ended. Section Start Main Menu
