DayboatOpen day racing boats, e.g. CODsE


8.1 The general course area will be the Conwy River Estuary.


9.1 The course for each race and class will be chosen from those described in the Course Card and signalled by a letter board displayed at the CRF Start Line prior to the warning signal or a special course decided by the Race Officer. The course will also be announced on VHF prior to the warning signal for the class. The schedule for each day for one or two races will be confirmed as part of the VHF daily briefing and/or course announcement prior to the first race warning signal.

9.2 The positions of the racing marks are given on the CRF Race Marks document.

9.3 All marks are to be rounded to PORT unless otherwise indicated in the Course Card or as announced by the Race Officer.


10.1 Handicapping Systems

10.1.1 Race results will be calculated using the Conwy River Festival Handicap system based on performance in previous Conwy River Festivals and local club handicaps, with a base handicap derived from the HALS race results system.

10.1.2 The Race Committee reserves the right to allocate a provisional Base Number (BN) to any boat for whom no BN is shown in the Base List, and to adjust the BN retrospectively if it appears manifestly incorrect.

10.1.3 The decision of the Race Committee with regard to the handicap of a boat shall be final.

10.2 Sails
Where a boat’s handicap is based on the use of a particular sail or sails, the boat is deemed to have elected to use those sails for the duration of the event and shall not use alternative sails.

10.3 Race formats
The races will be a conventional course, starting from a start line at the same time and sailing the course to the finish line.


11.1 The starting area will be in the Conwy estuary. The start line will be either:
(1) CRF line, which is the continuation of a line delineated by two white poles with orange triangles mounted on them adjacent to the entrance to Deganwy Marina. The use of an Inner Limit marker will be confirmed at the briefing. An inner distance mark does not form part of the Start Line, but yachts should not pass between it and the Deganwy Dock wall or the Committee (Start) Boat.
Or (2) the line between a Committee Boat and a nearby outer limit mark.
Or (3) The CYC Club line
Note that when racing is started from lines marked by poles on land, flag signals are given using flag boards (displayed at the Start Point), rather than actual flags.

11.2 If a Committee Boat start is used, this may be in the vicinity of CRF Start line or elsewhere as communicated by VHF radio. The Committee Boat will normally be CYC Guard Boat (Sior). When racing is started from a Committee Boat, alternative signals may be used from those prescribed by RRS 26. These alternative signals will be explained at the briefing.

11.3 The Classes will start together unless it is decided to offer separate starts, in which case the classes will start at 5 minute intervals, or as directed by the race officer by radio on the day

11.4 The Starting System prescribed by RRS Rule 26 will be used. See Appendix C of these Sailing Instructions for details of the RRS starting system.

11.5 Boats may be allocated into flights. The flight allocation will be announced in the daily morning radio briefing. The start of the first flight will be at the time shown in Appendix A. Successive flights will start at 5-minute intervals

11.6 The Sequence of starts is shown in the Schedule of Races, Appendix A.

11.7 Keeping clear of other starts
Boats are requested to keep well clear of the Start Line when other classes are starting.

11.8 Every effort will be made to broadcast sound signals by VHF


12.1 When at a boat’s starting signal any part of her hull, crew or equipment is on the course side of the starting line code flag X will be displayed and a second sound signal will be made. Such boats must return completely to the pre start side of the Start Line and then start correctly. Flag X will be displayed until all such boats have returned completely to the pre start side of the line or for a maximum of four minutes. After four minutes an OCS boat not returning will be disqualified. The Race Committee will endeavour, but not guarantee, to broadcast the identity of the boat(s) that have been recalled.

12.2 Competitors are reminded that a boat that has started incorrectly and is returning to the correct side of the Start Line has no rights and must give way to boats that have started correctly.


13.1 The postponement signal may be used at any time before the Starting signal of a race.

13.2 Postponement is signalled using Code Flag AP (the Answering Pennant) accompanied by 2 sound signals. The postponement continues until AP is removed, accompanied by 1 sound signal. The warning signal for the next race is given 1 minute after AP is removed. All subsequent starts are postponed accordingly.


The courses will not be changed after the start. But may be shortened.


15.1 The Finishing Line will be either the CRF Line, as defined in the course card, or a line between the flag mast on a Committee Boat and a nearby limit mark or the CYC Club line. The finish line shall be crossed from the direction of the previous mark of the course.

15.2 Shortened Course (amending RRS 32.2)
If a shortened course is signalled (Flag S accompanied by 2 sound signals), the signal means either:
(a) the finishing line is the line between the flag mast on a Committee Boat or RIB and a nearby rounding mark; or
(b) the race will finish when the leading boat next crosses the CRF line from either direction.

15.3 An announcement will normally be broadcast on VHF if the course is shortened for a particular class or classes.

15.4 Retirement
A boat which has retired from a race shall inform the Race Committee as soon as possible

15.5 Abandoned Races
A race which is abandoned for the day will not be re-sailed.

16. TIME LIMITS (amending RRS 35)

16.1 For all classes, racing will terminate at a time, each day, having regard to Deganwy Marina gate closing times (Conwy Marina gate closes approximately 10 minutes later). Gate closing times are published at the respective marinas.

16.2 Subject to SI 16.3, any boat which has not finished at the time limit will be scored DNF

16.3 The fixed time limit may be extended at the Race Committee’s reasonable discretion.

17. PENALTY SYSTEM (Changes RRS 44)

17.1 A boat may take a One-Turn penalty if she may have broken RRS 31 (touching a mark of the course) or a One-Turn penalty if she may have broken a rule of RRS Part 2 (infringing a sailing rule)

17.2 A penalty must be taken as soon as possible after getting well clear of other boats. The turn must include one tack and one gybe.


18.1 The time limit for lodging a protest, or request for redress, shall (unless extended by the Race Committee) be 1 hour from the time of the last boat to finish on that day and should be lodged at the Race Office. Boats should attempt to advise the Committee Boat of their intention to protest by VHF radio.

18.2 The protest or request for redress shall if possible be on the form provided by the RYA but in default thereof shall not be invalid provided that it complies in all other respects with the provisions of RRS 61 and 62 as amended by these SIs.

18.3 The protest or request shall be accompanied by a fee of £10, which may be refunded at the discretion of the Protest Committee.

18.4 Only the Race Committee may protest under rule 75.
