  3. Anchoring the Race Committee BoatThe Effects of Wind & Current • Your ability to anchor the RC boat in the desired location will impact several areas • Sight line to the pin • Whether or not the start/finish line is square • Location of the RC boat anchor rode relative to the course SMSA Race Management Training

  4. Anchoring the Race Committee BoatThe Effects of Wind & Current • Minimal current means the RC boat will be influenced more by the wind direction Wind Wind Wind x x x Is there anything about these three scenarios that jumps out at you? SMSA Race Management Training

  5. Anchoring the Race Committee BoatThe Effects of Wind & Current • However, when the current is stronger, the situation changes… • We, as RC, are forced to consider anchoring the boat in terms of vector math • This is an easy task when thecurrent & the wind align witheach other Current Wind SMSA Race Management Training

  6. Anchoring the Race Committee BoatThe Effects of Wind & Current • Things get trickier when the current & the wind do not align with each other Wind Wind Current Current Wind Vector Wind Vector Current Vector Current Vector SMSA Race Management Training

  7. Anchoring the Race Committee BoatThe Effects of Wind & Current • What happens when the current & the wind are against each other? • How will the RC boat lieat anchor? Wind ? Quite frankly, your guess is as good as mine in this situation Current SMSA Race Management Training

  8. Anchoring the Race Committee BoatConsiderations Before Anchoring • How deep is the water? And, how much scope will be needed? • What are the wind & current conditions? • Is the wind expected to increase or decrease while you are anchored? • Is the tide expected to change while you are anchored? • Has there been a significant amount of rain in the preceding week? • If so, you may be faced with an ebb tide, regardless of what the tide charts show SMSA Race Management Training

  9. Setting a Square LineStart Line Length • How long should you make the Start/Finish line? • US Sailing-recommended “rule of thumb” • 1.0-1.5 times the aggregate length of the largest class Aggregate = The summed length of all boats in a specified class Aggregate = (Boat Length)ί n Σ ί=m SMSA Race Management Training

  10. Setting a Square LineStart Line Length • Considerations: • A line that is too short will lead to recalls & the potential for lots of rules infractions • A line that is too long will exaggerate any lack of squareness present in the configuration • You usually will not know how many boats will be competing in a race/class until after setting the start • Therefore, you must make a “best guess of” the expected turnout In this scenario, the start line is too short – regardless of the wind & sea conditions SMSA Race Management Training

  11. Setting a Square LineFinish Line Length • In most cases, the start line remains the finish line • Usually not an issue since there are no one-design fleets • Generally, adequate boat spacing results from differences throughout the PHRF handicap band • Executing a “shorten course” is the most common instance where race committee considers finish line length • Considerations: • A line that is too short may lead to an unsafe situation for both competitors & race committee as boats jockey for room • A line that is too long will make it more difficult to identify a boat – or cluster of boats – at the far end of the line • Without resetting, errors in the squareness of the start line will be repeated for the finish line SMSA Race Management Training

  12. Setting a Square LineHow to Arrange a Square Line • When the wind is perpendicular to the weather mark, the start line set up is straightforward • Bearing(RC→Pin)° = Wind Axis° - 90° Assume the wind is from 165° Bearing(RC→Pin)° = 165° - 90° Bearing(RC→Pin)° = 75° Weather Mark Weather Mark Wind Wind Fair Start Best Case Scenario Unfair Start Port End Favored SMSA Race Management Training

  13. Setting a Square LineHow to Arrange a Square Line • More thought is required when the wind is not perpendicular to the weather mark • Set the start line square to the first mark of the course Weather Mark (Pt. No Point) Weather Mark (SMSA M) Navigation Mark(PR 1) Navigation Mark (Sandy Point) Fair Start Best Case Scenario Wind Wind Unfair Start Port End Favored SMSA Race Management Training

  14. Setting a Square LineImportance of a Square Line • One end will be favored over the other • It will be very difficult to identify the OCS boats when the majority are clumped at one end of the line – regardless of which end is favored • The ability to provide a fair start for all competitors is compromised when a line is not square • The same concept is also true for finish lines SMSA Race Management Training

  15. Setting a Square LineImportance of a Square Line • Assume there are 12 boats with an average length of 30’ in a start • Winds are steady at 12 knots with a moderate chop • You select a target start line length of 450’ RC boat 1° low Approximately 8’ below square RC boat 5° low Approximately 40’ below square It makes no difference if the RC boat is “high” or “low” of square, the math remains the same. RC boat 10° low Approximately 80’ below square SMSA Race Management Training

  16. Setting a Square LineImportance of a Square Line • What does it mean if the RC boat is 10° off-square on a 450’ starting line? • A boat at the “wrong” end of the line will have to sail further than a boat at the “right” end of the line x’ x2 + x2 = 802 2x2 = 6400 x2 = 3200 x = 57’ In this example, a boat will have to sail nearly 120’ just to “break even.” 80’ x’ SMSA Race Management Training

  17. Setting a Square LineImportance of a Square Line • Well, 120’ doesn’t sound too bad… • What boat speed do you typically see coming off the start line on a Wednesday night race? ** This assumes that NO time is lost during the tack ** SMSA Race Management Training

  18. Setting a Square LineTips for Setting a Square Line • Work to understand how the boat will lie at anchor with respect to the wind & current • Arrive on station early • Allow the boat to drift, then determine the direction relative to the wind & current • Position the boat to allow changes in the angle by adjusting the anchor rode • Leave enough rode to drop back • Set enough rode to pull up, with breaking off the bottom SMSA Race Management Training

  19. Setting a Square LineTips for Setting a Square Line • Adjust the anchor rode to improve the boat-to-pin angle • Let rode out • Drops the RC boat back • Increases the bearing angle to the pin • Take rode in • Brings the RC boat forward • Decreases the bearing angle to the pin • May be good for 5° up or down SMSA Race Management Training

  20. SMSA Race Management Training Starting and Finishing Races- - -Scoring the Races Keith Jacobs US Sailing Certified Club Race Officer

  21. Starting & Finishing Races / Scoring the RacesTopics • Importance of GPS Time • Assignment of Responsibilities • Course Selection • Starting Races • Warning Signal • Preparatory Signal • Classes Start Order • Calling the Line • Individual Recall • General Recall • Appendix S • How to Record Finishes • Determining Course Length • Scoring SMSA Race Management Training

  22. Starting & Finishing RacesImportance of GPS Time • Today, GPS time is the de facto time measurement system within the sailing community • Everyone can be on the same time-tick • Time throughout the RC and the competitor fleet is identical • Wristwatch oscillators are known to drift over time • Some manufacturers note ±10 seconds in a 30-day period • ALWAYS synchronize your watch before leaving the dock • Very beneficial when competitors must record their own finish times, such as the Middle Distance Races • Receivers – both ship’s units & handhelds – are widely available & relatively cheap • Today, there are wristwatches available that synchronize nightly to the GPS time signal from Fort Collins, CO SMSA Race Management Training

  23. Starting & Finishing RacesAssignment of Responsibilities • Assigning jobs to each member of the RC Team is one of the most important tasks • Need to consider each person’s strengths & weaknesses • Generally, there are more tasks than RC volunteers • However, people should be able to “multi-task” and cover a few jobs • For example, the Signaler could take wind readings before & after the start sequence • It’s important to have enough people on the RC boat to help with all the tasks • However, there is such as thing as “too many” helpers SMSA Race Management Training

  24. Starting & Finishing RacesAssignment of Responsibilities • Committee Boat Operator • Responsible for operating & equipping the RC boat • Ensure the RC boat is ready for the day’s work • Line Sighter • Sights the starting line & identifies OCS competitors • Makes the call for “Individual Recall” or “General Recall” • Sights the finish line & determines the order of finish • Mark Setter • Positions, sets, & relocates marks on the course • Monitors wind conditions (speed & direction) & keeps the PRO informed SMSA Race Management Training

  25. Starting & Finishing RacesAssignment of Responsibilities • Principal Race Officer (PRO) • The “CEO” of the RC Team • Makes the major race management decisions, within the provisions of the RRS & SIs • Has overall responsibility for all aspects of the race event • Scorer • Tabulates points & finishing times for all competitors • Calculates handicaps, if required • Incorporates Protest Committee results, if required SMSA Race Management Training

  26. Starting & Finishing RacesAssignment of Responsibilities • Signaler • Verifies that all required flags/pennants are available & ready to be hoisted • Class flags, Prep flags, Postponement, Recall flags, Shorten Course, etc. • Provides visual signal information to competitors from the RC boat • Status within the start sequence, Follow Me, Postponement, etc. • Sounder • Makes sound signals to draw competitors’ attention to the visual signals • Gun, air horn, whistle, etc. • A hail or shout from the RC is NOT a sound signal SMSA Race Management Training

  27. Starting & Finishing RacesAssignment of Responsibilities • Spotter-Recorder • Identifies & records all boats starting & finishing • Notes all boats who do not compete in a race • Records observations made/reported during the race • Boat X hit the leeward mark, Boat Y flying “B”, Boat Z retired, etc. • Always record the time of the incident • Timer • Ensures their watch is synchronized to GPS time • Using GPS receivers instead of a watch is not recommended since they are known to occasionally “skip” seconds due to signal processing • Calls the countdown sequence aloud for the start & the finish • Wind Reader • Observes & records wind direction & speed SMSA Race Management Training

  28. Starting & Finishing RacesCourse Selection • The course – and its length – should be considered for each class that has a start • You have the flexibility to post a different course for each starting class • RRS 27.1 requires the course to be posted by the Warning signal • There is no requirement to roll starts • There is no requirement to keep subsequent starts on a 5-minute “time tick” • Although, it can help both the timer & the competitors keep track of where they are in the countdown SMSA Race Management Training

  29. Starting & Finishing RacesStarting Races • Races started in accordance with RRS 26 • Also known as 5-4-1-GO! • The Warning period begins at 5 minutes before the start • The Preparatory period begins at 4 minutes before the start • Penalties signaled during the Preparatory period go into effect at 1 minute before the start RRS 26 SMSA Race Management Training

  30. Starting & Finishing RacesWarning Signal • The course must be displayed no later than the warning signal • For a race with multiple classes: • “The warning signal for each succeeding class shall be made with or after the starting signal of the preceding class.” • You may roll the starts – but it is not required • Consider the wind & sea-state conditions when deciding whether to roll the starts STRIKE with 1 sound signal,at the start Class Flag Class Flag HOIST with 1 sound signal,5 minutes before the start RRS 27.1 SMSA Race Management Training

  31. Starting & Finishing RacesWarning Signal Class/Warning Flags for Wednesday Night Informal Racing Spinnaker - A PHRF ≤109 Spinnaker - C PHRF ≥146 Non-Spinnaker All PHRF Ratings Spinnaker - B PHRF 110-145 May Be Consolidated into 1 or 2 Starts, Depending Upon the Number of Boats That Show Up for That Evening Class/Warning Flags for Weekend Formal Racing Non-Spinnaker All PHRF Ratings Spin A-C All PHRF Ratings SMSA Race Management Training

  32. Starting & Finishing RacesPreparatory Signal • Starting marks must be set by the time of the preparatory signal • There are 5 allowable preparatory signals • There are also 4 penalty signals that may be used in lieu of the “P” flag • Used to help control overly aggressive classes • Typically invoked in an ascending order of severity following General Recall(s) STRIKE with a long sound signal, 1 minute before the start HOIST with 1 sound signal,4 minutes before the start “Preparatory Signal.” RRS 27.2 SMSA Race Management Training

  33. Starting & Finishing RacesPreparatory Signal Routine Preparatory Signal. There are no penalty conditions in effect. Penalty Preparatory Signal, RRS 30.1. The Round-An-End rule is in effect. Penalty Preparatory Signal, RRS 30.2. The 20% Penalty is in effect. Penalty Preparatory Signal, RRS 30.1 & 30.2. Both the Round-An-End Rule & the 20% Penalty are in effect. Penalty Preparatory Signal, RRS 30.3. The Black Flag Rule is in effect; immediate disqualification upon violation. RRS 30 SMSA Race Management Training

  34. Starting & Finishing RacesClasses Start Order • Frostbites • Non-Spin 1300 Warning; 1305 Start • Wednesday Nights • Non-Spin 1825 Warning; 1830 Start • Spin - C Check SIs for times • Spin- B Check SIs for times • Spin - A Check SIs for times • Weekend • Non-Spin Check SIs for times • Spin (A, B, C) Check SIs for times SMSA Race Management Training

  35. Starting & Finishing RacesCalling the Line • At the START • The “starting line” is the plane that extends from the course-side edges of the two items marking the ends of the starting line • “Items” = Halyard, Pole, Inflatable Mark, Buoy, etc. • A boat is considered “On Course Side” when at her starting signal, “any part of her hull, crew, or equipment is on the course side of the starting line” SMSA Race Management Training

  36. Starting & Finishing RacesCalling the Line Clear, or Pre-Start Side Course Side Pin This is NOT an OCS situation since no part of the boat, crew, or equipment are on the course side of the starting line Wind This IS an OCS situation since the bow of the boat is on the course side of the starting line SMSA Race Management Training

  37. Starting & Finishing RacesCalling the Line • At the FINISH • The “finish line” is the plane that extends from the course-side edges of the two items marking the ends of the starting line • “Items” = Halyard, Pole, Inflatable Mark, Buoy, etc. • A boat is considered “Finished” 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” • The entire boat is not required to pass through the line • The boat must stay clear of the RC boat, mark, & other competitors who are still racing • If a “finished” boat commits a foul, they are required to exonerate themselves, then refinish SMSA Race Management Training

  38. Starting & Finishing RacesCalling the Line Pin Wind Pin Pin “Finish” is recorded as soon as the belly of the spinnaker touches the forward edge of the plane of the line These are NOTlegitimate finishes since gear is not in its “normal position” SMSA Race Management Training

  39. Starting & Finishing RacesIndividual Recall • RRS 29.1 • “When at a boat’s starting signal any part of her hull, crew or equipment is on the course side of the starting line or she must comply with rule 30.1, the race committee shall promptly display flag X with one sound.” STRIKE with no sound signal – after the last boat has cleared or after 4 minutes, whichever occurs first HOIST with 1 sound signal “Individual Recall.” RRS 29.1 SMSA Race Management Training

  40. Starting & Finishing RacesIndividual Recall • The key requirement is for RC to “promptly” signal Individual Recall • “Promptly” has been left vague & undefined • However, you should be able to complete the signal within a few seconds • You do not have time to find the flag, attach it to a halyard, then hoist it • The flag is flown until either all boats clear themselves, or 4 minutes have elapsed – whichever occurs first RRS 29.1 SMSA Race Management Training

  41. Starting & Finishing RacesIndividual Recall • The entirety of the boat, crew, & equipment must all be on the pre-start side of the line in order to clear the OCS • Never dip the flag to acknowledge that an individual boat has cleared herself Suppose that crew on Blue saw the X flag “dip” for Green while at position 3. Has this boat cleared herself? RRS 29.1 SMSA Race Management Training

  42. Starting & Finishing RacesIndividual Recall • Can you manage an Individual Recall from this scenario? RRS 29.1 SMSA Race Management Training

  43. Starting & Finishing RacesIndividual Recall • Keep an eye on all OCS boats – you must still clear them when they come back • Keep track of how long the Individual Recall flag has been flown • It must be removed at T+4 minutes if all boats do not come back to clear themselves RRS 29 SMSA Race Management Training

  44. Starting & Finishing RacesGeneral Recall • RRS 29.2 • “When at the starting signal the race committee is unable to identify boats that are on course side of the starting line or to which RRS 30 applies, or there has been an error in the starting procedure, the race committee may signal a general recall.” STRIKE with 1 sound signal – 1 minute before WARNING signal for the class HOIST with 2 sound signals “General Recall. The warning signal will be made 1 minute after removal.” RRS 29.2 SMSA Race Management Training

  45. Starting & Finishing RacesGeneral Recall • There may be an “unfairness” associated with a General Recall – regardless of which decision you make • A General Recall is not fair to the boats that started fairly • If you can identify every OCS boat, signal Individual Recall • However, an Individual Recall is unfair if OCS boats are not identified • The PRO must weigh the disadvantages of either decision • Stipulates that the recalled class will be the next one to go back into the start sequence • Some SIs have been modified direct that the recalled class goes to the end of the remaining classes to be started RRS 29.2 SMSA Race Management Training

  46. Starting & Finishing RacesGeneral Recall • What does a General Recall look like? RRS 29.2 SMSA Race Management Training

  47. Starting & Finishing RacesAppendix S • Sound-Signal Starting System • Used by our Small Boat Program for Thursday night racing • The course & postponement signals may be made orally • The Individual Recall flag does not have to be displayed to indicate OCS • An oral hail of sail numbers or some other distinguishing features is all that is required • Audible signals govern over visual signals • 3-minute start sequence Warning Preparatory Start 3’ 2’ 1’30” 1’ 30” 20” 10” 5” 4” 3” 2” 1” 0 TIME SOUND 3L 2L 1L 3s 1L 3s 2s 1s 1s 1s 1L 1s 1s 1s RRS Appendix S SMSA Race Management Training

  48. Starting & Finishing RacesHow to Record Finishes • When possible, employ multiple recorders • Most smartphones have a voice recorder app • Stay calm when things get congested • Record sail #, boat name, or any distinguishing feature • Use a recorder’s shorthand to minimize how much information must be written • Use the same watch to call finish times as was used for the start countdown • What else? • Is a protest flag flying from the backstay? • Does the number of finishers match the number of starters? • Double-check everything & have the recorders cross-check their sheets SMSA Race Management Training

  49. Starting & Finishing RacesHow to Record Finishes • Recorder’s Shorthand Clear, easy-to-read lettering Don’t use colons, leave a space Don’t rewrite the “hour” if it doesn’t change Don’t rewrite the “minute” if it doesn’t change SMSA Race Management Training

  50. Scoring the RacesDetermining Course Length • For Wednesday night racing, course length will be automatically calculated in the scoring spreadsheet • This is possible since we utilize a fixed starting location • Weekend racing provides some options • Setting the start/finish line off an existing SMSA mark allows you to utilize a scoring spreadsheet to calculate the course length • Setting the start/finish line away from an existing mark will require a GPS to determine your anchor point • You must calculate the distance from the start line to the first mark & the distance from the last mark to the finish line • Do not attempt this type of course configuration if you are not familiar or comfortable with use of a GPS • For small boat racing, distance is irrelevant since it is time-on-time handicapping or one-design racing SMSA Race Management Training
