Sailing Instructions For Pursuit Races

  • 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.


     IBRSC Sailing instruction supplement for Lockdown races – Jul 12, 2020 until further notice…

    The normal sailing instructions (as on the web site) will apply with the following changes. Sections in parentheses are explanations not part of the instructions.

    SI 6: Entry via the board is no longer required, but to ensure you are correctly identified in results if you are not the usual sailor / registered keeper of a boat on the membership database you should email the sailing secretary – if you are in a club boat this is essential. Please do not just ‘tell the RO’ from a distance. We will record results against sail numbers and fill in names where we can – these can be retrospectively corrected. Send your class/sail number to sailing-sec@islandbarn.org.uk

    Race officer should send a scan of the results sheet to the same address. (Better than handling paper from a distancing perspective). If RO can’t scan (cell phone picture mailed is usually readable) an email with the class/sail number is good enough.  

    SI 8 course: The course will be shown by mark numbers displayed by the start line. 

    SI 10 start line: The start line will be between the shore start flagpole and an outer distance mark which may be a regular sailing mark or a moveable mark. An inner distance MAY but does not have to be set. (Shore start to allow distancing between Race Officer and Assistant)

    The races will be Pursuit races of 45 minutes from the Topper 4.2 start. (Pursuit races to minimise start line crowding). Start times will be posted in the clubhouse windows and on the web site.

    Pursuit instructions are changed as:

    There will be a start hoot every 30 seconds.  The half minutes will be indicated by the numbers being held up on their side most significant on the top - read vertically downwards. The timing of numbers remains similar, up for approximately 10 seconds before to 10 seconds after (rather than 20 seconds before to give the poor person holding them up 10 seconds break to change number).

    At the end of 45 minutes there will be a long hoot and the safety boat will drive back down the fleet to note positions. Please do not head in or alter position until SB has noted you. This may take longer than usual because SB will likely be single handed. (SB driver may use radio to RO to call out the sail numbers as an easier way to record than drive and write with one person, but the viability of that needs checking).

    Start times will be published and put on the club house window as well as the web site. Please observe social distancing as you look.

    SI 16 protests

    We strongly discourage protests during phase lockdown. An arbitration may be held with social distancing, but competitors are strongly advised to keep well clear of each other. (Please do not push your luck and regard avoid all contact - regard one metre apart as if contact). If in doubt make your turns at the earliest opportunity where you will not get in anyone’s way.


    Race Series

    There will be two back to back pursuit races of 45 minutes on Sundays (10:30 and 11:30 or as soon as practicable first starts), and one race on Wed evening 19:20 for Topper 4.2 start  (This puts the laser start close to the traditional 19:30 because of the pursuit starts). We will not initially be having any Saturday races.
