When does RRS 42 apply? RRS42 Sylvie HARLE (IJ-FRASH1) – V0.4 GB

When does RRS42 apply? • RRS42 applies while racing (RRS part 4) - 5 mn - 4 mn - 1 mn START FINISH Class Class Flag Flag Racing  RRS 42 Sylvie HARLE (IJ-FRASH1) – V0.4 GB

What does RRS42 say? RRS42 Video: mn.s = example in ISAF video Sylvie HARLE (IJ-FRASH1) – V0.4 GB

What does RRS42 say? 42.3: exceptions 42.1: basic rule 42.2: prohibited (= permitted) 42.3 (a) : rolling to 42.2 (a) : pumping facilitate steering 42.1: use only wind and water to increase, 42.3 (b) : exagerate maintain or decrease 42.2 (b) : rocking rolling while tacking speed 42.3 (c) : one pump per 42.2 (c) : ooching wave 42.3 (d) : scull to close 42.2 (d) : sculling hauled …/… 42.2 (e) : repeated tacks 43.3 (g) : any mean to or gybes … give help …/… Sylvie HARLE (IJ-FRASH1) – V0.4 GB

42.1: basic rule RRS 42.1: basic rule 42.1: Except when permitted in rule 42.3 or 45, a boat shall compete by using only the wind and water to increase, maintain or decrease her speed. Her crew may adjust the trim of sails and hull, and perform other acts of seamanship, but shall not otherwise move their bodies to propel the boat. Etc.. Video: 0.12 Sylvie HARLE (IJ-FRASH1) – V0.4 GB

42.3: exception 42.2 (a): basic rule (g) Any means of propulsion may be used to help a person or another vessel in danger. You can use any way to help ! (h) To get clear after grounding or colliding with a vessel or object, a boat may use force applied by her crew or the crew of the other vessel and any equipment other than a propulsion engine. However, the use of an engine may be permitted by rule 42.3(i). You can push… but no motor ! Video: 0.27 Sylvie HARLE (IJ-FRASH1) – V0.4 GB

42.2: prohibited 42.2 (a): pumping Without limiting the application of rule 42.1, these actions are prohibited: (a) pumping: repeated fanning of any sail either by pulling in and releasing the sail or by vertical or athwartship body movement; Video: 1.34 / 1.58 Sylvie HARLE (IJ-FRASH1) – V0.4 GB

42.3: exception 42.2 (a): pumping 42.3 (c) Except on a beat to windward, when surfing (rapidly accelerating down the front of a wave) or planing is possible, the boat’s crew may pull in any sail in order to initiate surfing or planing, but each sail may be pulled in only once for each wave or gust of wind. 1 pump per wave allowed to initiate the surf or planning … when surfing conditions ! No surfing conditions  no pump ! 42.3 (e) If a batten is inverted, the boat’s crew may pump the sail until the batten is no longer inverted. This action is not permitted if it clearly propels the boat. Video: 1.14 Sylvie HARLE (IJ-FRASH1) – V0.4 GB

42.2: prohibited 42.2 (b): rocking Without limiting the application of rule 42.1, these actions are prohibited: (b) rocking: repeated rolling of the boat, induced by (1) body movement, (2) repeated adjustment of the sails or centreboard, or (3) steering; Video: 0.20 Sylvie HARLE (IJ-FRASH1) – V0.4 GB

42.3: exception 42.2 (b): rocking 42.3 (a) A boat may be rolled to facilitate steering. « Serpentine » OK.. if consistent with waves … 42.3 (b ) A boat’s crew may move their bodies to exaggerate the rolling that facilitates steering the boat through a tack or a gybe, provided that, just after the tack or gybe is completed, the boat’s speed is not greater than it would have been in the absence of the tack or gybe. OK.. if no more speed after tack/gybe Sylvie HARLE (IJ-FRASH1) – V0.4 GB

42.2: prohibited 42.2 (c): ooching Without limiting the application of rule 42.1, these actions are prohibited: (c) ooching: sudden forward body movement, stopped abruptly; Sylvie HARLE (IJ-FRASH1) – V0.4 GB

42.2: prohibited 42.2 (d): sculling Without limiting the application of rule 42.1, these actions are prohibited: (d) sculling: repeated movement of the helm that is either forceful or that propels the boat forward or prevents her from moving astern; Most often just before the start … ..or to pass a mark… Sylvie HARLE (IJ-FRASH1) – V0.4 GB

42.3: exception 42.2 (d): sculling (d) When a boat is above a close-hauled course and either stationary or moving slowly, she may scull to turn to a close-hauled course. Scull in 1 direction to close-hauled Not below No offset previous close-hauled ! sculling! (f) A boat may reduce speed by repeatedly moving her helm. Sylvie HARLE (IJ-FRASH1) – V0.4 GB

42.2: prohibited 42.2 (e): repeated tacks or gybes Without limiting the application of rule 42.1, these actions are prohibited: (e) repeated tacks or gybes unrelated to changes in the wind or to tactical considerations Most often in very light winds Sylvie HARLE (IJ-FRASH1) – V0.4 GB

RRS 42 : summary for laser-optimist Use only wind and … everything is but water while racing … permitted to help No « paddle » effect basic Pumping (repeated) with One pump per wave sheet/body Rolling tack/gybe (if no Rocking (repeated) repeat, no more speed) Ooching Scull in one direction to Sculling (repeated) close-hauled Repeated tack/gybes without tactical reasons Sylvie HARLE (IJ-FRASH1) – V0.4 GB

Appendix P: how does it work? Sylvie HARLE (IJ-FRASH1) – V0.4 GB

Appendix P : signalling Appendix P applies only if specified in Sailing Instructions.. Read them ! P1 SIGNALLING A PENALTY A member of the protest committee or its designated observer who sees a boat breaking rule 42 may penalize her by, as soon as reasonably possible, making a sound signal, pointing a yellow flag at her and hailing her sail number, even if she is no longer racing. A boat so penalized shall not be penalized a second time under rule 42 for the same incident. + FRA 162964 ! Sylvie HARLE (IJ-FRASH1) – V0.4 GB

Appendix P : penalties 2nd penalty in >=3 penalty in 1st penalty in the event the event the event What you have to do Two-Turns- Retire Retire penalty (promptly) (promptly) (immediately) Score Finishing DNE  DNF position Score if incorrect or no penalty DNE all races DNE  DSQ  Sylvie HARLE (IJ-FRASH1) – V0.4 GB +RRS69?

Appendix P : penalties (RRS44) tack Two Turns = gybe 2 X 2 2 tacks + 2 gybes ! Turns 2 nd and further penalty RET = Retire leave the racing area immediately Appendix P may be modified in Sailing Instructions Read them carefully ! Sylvie HARLE (IJ-FRASH1) – V0.4 GB
