1: Race Management Equipment
The equipment and information required to complete Officer of the Day will be given to you prior to the race. It is your responsibility to arrange when and where the equipment can be handed over to you.
Equipment will be retained by the Racing Secretary when not in use and should be obtained from him when needed. On occasions where racing is competed on two consecutive days you should arrange to collect the equipment from the previous days O.D.
Equipment List: (supplied)
- Stopwatch x2
- Fog Horn
- List P.Y. Handicaps
- Calculator
- Club Diary
- Course indicator boards and stand (Stored in the Black Hut)
- Emergency instructions and telephone contact numbers.
- Race Record Sheet
- Suggested racing courses
You should also have the following with you:
- VHF radio
- Mobile phone
- Watch or Stopwatch
- Pen
Stopwatch:
Two electronic stopwatches are provided in the OD's pack a mechanical stopwatch is also provided as a back up. The mechanical stopwatch should be fully wound at the start of the race and checked periodically to ensure that it is not allowed to run down. Note that the mechanical stopwatch counts up to 30 minutes only, for laps/races of a longer duration a cumulative time will have to be used.
Course boards:
The boards are stored in the Black Hut. The hut is secured by a padlock (code 9292) and by a slide bolt that is released by a mechanism along the underside of the door.
The boards and stand should be returned to the hut after use. You must ensure that the door is fully closed and secured with the padlock.
After the race equipment and completed Race Record Sheet should be given to the Sailing Secretary.
2 : Setting a Course
- Anchor four or five boat lengths off the outer corporation mark at an angle that allows boats to start to windward at about 45 ° to the line.
- Consider the Wind direction and strength and select an appropriate course.
- Set the course board so that the chosen course is displayed and fix it to your boat so that entrants crossing the line can easily see it.
3 : Suggested Courses
Course A: Start northwards leaving OD boat to port, thence to C12, C18, OD boat, C16 all to port. Finish leaving OD boat to port (8.5 Miles)
Course B: Start north-westwards leaving OD boat to port, thence to C14 and C16 both to port and OD boat to port. (2 or 3 laps at OD's discretion) (3.8 Miles per lap)
Course C: Start northwards leaving OD boat to port thence to C12, C18 and OD boat all to port. (2 laps). Finish leaving OD boat to port (5.9 Miles per lap)
Course D: Start south-westwards leaving OD boat to starboard, thence to C18, C12, OD boat, C16 and C14 all to starboard. Finish leaving OD boat to starboard. (8.5 Miles)
Course E: Start south-westwards leaving OD boat to starboard, thence to C16 and C14 both to starboard and OD boat to starboard. (2 or 3 laps at OD's discretion) (3.8 Miles per lap)
Course F: Start southwards leaving OD boat to starboard, thence to C18, C12 and OD boat all to starboard. Finish leaving OD boat to starboard. (5.9 Miles)
4 : Sketch chart of the racing area
5 : Conduct of the race.
Use two watches.
10 minutes to start of race.
- Give THREE sound signals
- Start watch number one, use watch to count down 5 minutes.
5 minutes to start of race.
Start of race.
- Give ONE sound signal
- Start watch number two. There are now two watches running with a ten minute interval between them.
- Maintain observation of the race and note down each boat's lap times.
- As each boat finishes, take it's elapsed time and sound a signal to indicates it's completion.
- The O.D. shall recall any premature starters as quickly as possible in accordance with rules in the Club diary.
- Protests and shortening course - see Club diary for details.
- VHF radio may be used to reinforce your sound and visual signals. Club radio - Channel 37 (M).
6 : Race Safety
Give priority to safety. If the weather deteriorates, abandon your station and return to your mooring.
In the case of failing winds, note the times as each boat pass each mark.
When you decide to abandon, give a long loud sound signal, this may be reinforced using VHF radio. Wait at least 45 minutes after high water before doing this.
7 : Calculating Results.
Based on P.Y. Handicap.
Elapsed time (in seconds) ÷ P.Y. No x 1000
The boat with the lowest corrected time wins.
Example -
Elapsed time = 5842 seconds
P.Y. No = 1180
5842 ÷ 1180 x 1000 = 4950
Based on L.B.S.A. Handicap.
Elapsed time (in seconds) x (L.B.S.A. ÷ 10000) x 1000
The boat with the lowest corrected time wins.
Example -
Elapsed time = 5842 seconds
L.B.S.A. = 0.7145 (7145 ÷ 10000)
5842 x 0.7145 x 1000 = 4174109
