Sailing Instructions For Pursuit Races

< Back

Rules

All competitors shall comply with the rules of Island Barn Reservoir Sailing Club, on display in the clubhouse.  All races shall be sailed according to the International Sailing Federation (ISAF) Racing Rules of Sailing (RRS) 2009-2012 with latest amendments, the RYA Racing Charter, the prescriptions of the Royal Yachting Association (RYA), the rules of the individual classes being sailed, and the Island Barn Reservoir Sailing Club Sailing Instructions for Club Racing, except as any of these are changed by these sailing instructions.

The standard club sailing instructions will be referred to in these sailing instructions as SI nn, where nn is the numbered heading in the standard instructions.

Starting Times

The starting times in SI.10 will be taken to mean the start numbers allocated to each class which correspond to the time in minutes after (or before if a minus value) the start time specified in the sailing programme for the class starting at 0 (zero).

Starting Signals

This instruction replaces SI.12.

The class starting at ZERO will receive a warning signal (flag “H” and one sound) at four minutes before their start time; followed by a preparatory signal (flag “P” and one sound) at two minutes before their start.  Both flags will be lowered at the start.  Thereafter, a sound signal will be made every minute until the last class has started.  The start numbers will be displayed at the start line for approximately 20 seconds before and 10 seconds after each sound signal.

Classes with negative start numbers will receive a one minute preparatory sound signal with no flag followed by a sound signal at their start time.  It is the entrant’s responsibility to synchronise watches with the Race Officer to ensure they start on time.  The Race Officer may display their start number without a minus sign as an aid.

Recalls

General recalls will not be possible and RRS rule 29.2 will not apply.  Individual recalls will be given in accordance with RRS rule 29.1 (flag X)

Shortening Course

The Race Officer will only shorten course as a last resort or where his team cannot provide adequate safety cover.  In such a case the race will be finished in accordance with SI.15 and all finishers will be timed.  The results will then be calculated on each boat’s elapsed time and Portsmouth Number, making the best allowance possible for boats that have completed different numbers of laps.

Time Limit

SI.17 will not apply.

Finishing

Finish Time

SI.16 will not apply.  The finish will occur at a specified time after the ZERO start number (usually 75 minutes in summer, 60 minutes in winter) and will be notified by a prolonged sound signal from a committee boat on station at a finish line in the vicinity of the leading boats.  This signal may be repeated several times by other committee boat(s) around the course.

All boats will continue racing until finished by a committee boat at a finish line or by a committee boat travelling down the fleet. 

Finish Line

The standard intended finishing line may be between a committee boat and a mark of the course, or between two committee boats.

If the race is to end on an upwind leg then the Race Officer can elect to set up a finish line part way along the leg.  In this case the finish line will be between the Committee Boat flying flag “S” and one of the start line buoys or another committee boat.  The finish line will straddle a straight line between last mark and the intended upwind mark.  To finish, a boat must pass through this finish line.

Multiple lines may be used at different parts of the lap to attempt to record all positions as soon as possible after the finish time. A boat finishes as soon as it crosses any finish line.

If possible a travelling line will be used. When short handed, the ‘line’ may be a single boat travelling back down the course sighting a ‘line’ perpendicular to the course.

It is the entrant’s responsibility to be aware of the finish time and look out for finish lines set up this way. It is desirable that boats not overtake once the time signal is given to help the Race Office get a fair result that represents the positions at the time limit.
