Mission Bay Yacht Club Ocean Races

Saturday & Sunday, October 17 & 18, 2020 SAILING  INSTRUCTIONS

RULES: These races shall be governed by the “rules” as defined in the Racing Rules of Sailing (RRS) 2017 - 2020, these Sailing Instructions, and the class rules for participating classes.


These races are open to all members of MBYC wishing to race on the ocean. Five (5) or more boats are required in order to qualify as a class Fleet for a Start.

Eligible skippers must sign up online at mbycracing.com no later than the completion of the Skipper’s Meeting on the morning before racing.


Notices to competitors shall be posted on the official bulletin board located at the south end of the Main Clubhouse near the flagpole.

Any change to the Sailing Instructions shall be posted no later than fifteen (15) minutes after the end of the Competitors Meeting or one (1) hour prior to the start of the first race of the day.


A Competitors Meeting will be held at 1000 hours on Saturday, 17 October 2020 at the flagpole on the main deck of the clubhouse.


Signals made ashore shall be displayed from the main deck flagpole of the MBYC clubhouse.

When the AP Flag is displayed ashore, the meaning is “Racing is postponed. Do not leave the Club area.” The Warning signal for the first race shall not be made less than sixty (60) minutes after the AP Flag is lowered.


In accordance with the RRS, oral changes to the Sailing Instructions may be made on the water. A change is in effect when the Race Committee Signal Boat (RCSB) displays code Flags L over A with one sound signal. This will mean “come within hail of the RCSB” in order to receive oral changes.


The Race Committee shall attempt to complete three (3) and possibly four (4) races each day depending on wind, weather, racing circumstances, and at the discretion of the PRO.

The Warning Signal for the first race shall be at 1200 hours (noon).


The racing area shall be on the ocean approximately one (1) nautical mile NW of the Mission Bay Channel jetty.


The class flags to be used shall be the standard and usual class flags for the various racing fleets / classes competing at MBYC.

Check In:

Before the Start of racing, all boats are required to Check In with the Race Committee Signal Boat (RCSB) when the code Flag L is displayed by sailing past the stern of the RCSB on Starboard tack. It is incumbent on each skipper of a racing boat to ensure that they have been acknowledged.


The courses shall be as described in Appendix A of these instructions.

The number of the Course shall be displayed on the RCSB by use of a numerical International Code Flag.

The bearing to the first mark shall be displayed on a white board from the stern of the RCSB.

All marks are to be left to Port.

When Finishing Downwind, all boats must round the Orange Flag on a floating staff that marks the port side of the Start Line before proceeding to the Finish Line aft of the RCSB.


Primary marks “W”, “R”, and “L” shall be ORANGE Tetrahedrons.

An alternate Windward, “W”, mark shall be a YELLOW Tetrahedron and will be used as a new “W” for a wind shift and when the Change of Course code Flag C is displayed on a Race Committee boat with multiple sounds.

The temporary alternate YELLOW Tetrahedron will be replaced with the standard ORANGE Tetrehedron as soon as reasonably possible.

For all boats in the Multi-Hull Class (F-18s, A-cats, etc), the Windward “W” mark shall be an ORANGE CYLINDER (not a tetrahedron) that will be set some distance to Windward of the standard Orange Tetrahedron.

This will allow the Race Committee to set a longer course for the Multi-Hull competitors.

The Multi-Hull Fleet shall use the standard and usual “R” and “L” marks, Start Line and Finish Line as set for the other competitors in the mono-hull fleets.

THE START:The Starts will be in accordance with RRS 26 except for the following changes:


There shall be “rolling starts” one class after another

However, there will be a ONE (1) Minute Interval between the Start Signal of one class and the Warning Signal of the next class.

This changes RRS 26.

The Start Line shall be between an Orange Flag on the RCSB on the starboard end of the line and an Orange Flag on a floating staff on the port end of the line

As a courtesy to competitors, the RCSB may call attention to the Warning Signal for the next race sequence by signalling with multiple sounds ONE (1) Minute before the first Warning Signal of a particular sequence and/or by VHF radio  communication.

No boat shall start more than three (3) minutes after her starting signal. Any boat starting later shall be scored DNS.

The Starting Sequence and class flags shall be at the discretion of the PRO. Do Not Assume that the start of any one class is in any particular position in the Starting Sequence from race to race.


Recalls shall be signaled in accordance with RRS 29.1 & 29.2.

The Race Committee will attempt to hail any and all boats that are on the course side (OCS) at the start of a race by “loud hailer” and/or by broadcast on VHF radio.

However, there shall be no grounds for redress under RRS 62 if there is no hail, if there is a failure to hear the hail, and/or if there is some debate about the timing or the order of the hail.


The Windward Finish Line for All competitors (including Mult-Hull Fleet) shall be located approximately one hundred (100) yards to the windward and to the starboard side of the ORANGE TETRAHEDRON “W” mark.

This finish line will be between an Orange Flag on a Race Committee boat and an ORANGE Flag on a floating staff, as indicated in Appendix A.

The Downwind Finish Line shall be between an Orange Flag on the Race Committee Signal Boat (RCSB) and a floating staff displaying an Orange Flag in the same location as the Start Line, as indicated in Appendix A. However, the Downwind Finish Line may be shorter.


The time limit for finishing each race shall be one (1) hour.

Boats failing to Finish within twenty (20) minutes of the first boat of the same class shall be scored DNF. This changes RRS 35.


Scoring will be in accordance with the low point scoring system in Appendix A of the RRS.

One race shall constitute a regatta.


A boat intending to Protest must notify the Race Committee IMMEDIATELY upon finishing the race in question and must identify the boat being protested by sail number.

Protests must be submitted in writing on forms available at the MBYC main office and must be lodged there within sixty (60) minutes of the time that the RCSB returns to the dock.


All competitors are encouraged to carry a VHF radio. RRS 41 and 60.1.a are hereby modified in order to prohibit a competitor from protesting another if this practice is a violation of class rules.

Radios may be used in transmit mode in the event of an emergency requiring assistance or in order to notify the Race Committee of a boat’s intent to retire from racing.

Radios may be used in receive mode at all times. However, radios are Not to be used for any communication between competitors during racing and should not be used to gain any unfair advantage regarding conditions, tactics, or strategy from an outside source when racing.

The radio channel to be used shall be VHF Channel 71.


A designated person aboard the Race Committee Signal Boat may report to competitors on the established VHF radio channel certain information regarding pending start sequences, course number, bearing to the windward mark, and/or visual signals displayed by the Race Committee as a Courtesy to Competitors.

However, such broadcasts are a Courtesy to Competitors and Do Not In Any Way alter the competitor’s responsibility to observe and comply with the Race Committee’s visual signals which govern the conduct of the racing.

Errors and/or omissions on the part of the designated person performing the courtesy broadcasts shall not be considered as grounds for redress.


Sign In: Skippers of boats intending to race on the ocean are required to sign in on a Sign In Sheet posted on the bulletin board on the outside of the south wall of the main clubhouse indicating their intent to proceed to the ocean.

Check In: Each competing boat is also required to Check In with the Race Committee Signal Boat when displaying the code Flag L prior to the first Warning Signal of racing for the day. Boats checking in shall sail by the stern of the RCSB on Starboard  tack.

Retiring Boats: A competing boat that retires from a race and/or intends to retire from racing for the day and leave the racing area is required to notify the Race Committee of this action. This can be done using VHF radio communication on Channel 71.
