We had a big event at Bough Beech SC on Saturday and although we had 3 people combining to record the finishers there were moments when 6 or 7 boats were finishing together and 30 finishing within 3 or 4 minutes. Our recording broke down - does anybody have a good technique for dealing with this problem?

Some of the big keelboat events in the Solent solve this problem by having a final short leg that is deliberately processional. They similarly might have 30-40 boats finishing within a couple of minutes. So you might do start-beat-run-beat-run. From the last leeward mark, the line is 400m away on a close fetch. The last leeward mark pretty much arranges the boats into a single file and since it is practically impossible to overtake on a close fetch, they stay that way to the finish.

I've used a dicta-phone or small recording device so I can just say the numbers in quick succession and sort out the order later; I'd also consider a Video camera on the finish line for this reason too. Had many a conversation about putting a small tracking device in boats so that you did not have to worry about this.... |

In to, toppers with loads of boats, trapezoid courses with a fetch at the end, which as Stephan said, is deliberately preocessional as well as often a video camera , also we have championship numbers so long sail numbers don't have to be read, 73 is much easier thsan 44981- though this wouldn't be possible for a mixed class one off event.

The software I wrote to do our race results has a special screen to help with this.
Whenever the space bar is pressed on the 'time sheet' screen, the time of day is recorded on screen. Up to ten times are displayed before the display scrolls up. Therefore if you get several boats come across at virtually the same time, you just press the space bar quickly for each boat. Someone else records the actual order they finish in by sail number, which can than be married up with the times recorded on screen. ![]() Edited by James Bell |

Yes we've tried the dictaphone and video camera techniques. The dictaphone is not a good idea in that you think you've recorded the times and numbers but if there's any mistake its too late to do anything about it when transcribing it ashore. The video is slightly better in as mych as you can play it slow or pause as many times as you like, but again if you've missed something its too late to look up the fleet and fill in the gaps. However the idea of a short close reach to get the boats into single file is worth consideration. So thanks for the thoughts. |

And thanks James for your suggestion. We have a race timer with the ability to do just what you suggest but marrying up the boat numbers with the times is a problem. I'll give you the benifit of my experience. Don't do anything fancy, for instance don't try and separate out Juniors from Seniors and record their times on separate sheets (as was attempted on Saturday), that just takes extra time and can cause errors. Just simply record sail number and time as each boat passes. Don't try and keep separate lists for separate laps, just keep recording number and time and the number of laps of each competitor will emerge from the records you keep. Don't write down the whole long number - Lasers prompt you by making the higher digits red - for you to ignore, try the same technique for Toppers, Mirrors and other high numbered classes. Do use lined paper and if loads of boats cross at almost at once just get the number of each and the time of the first and the last and interpolate.

I said "close fetch" which isn't quite right, but what I was trying to express was something just off close-hauled - so perhaps a bit closer than "close reach" would imply. The point is that it's a "no overtaking" point of sailing. |

Having suffered on numerous occasions with trying to accurately record boats coming over the line (especially large G Handicaps) I now adopt the following (where the class permits) Set a course with a short fetch to the line. There are samples for single class events on www.sailor.org.uk/raceman. For large GH events, I use a trapezoid where the committee boat is about 30 yards up from mark 4 & the pin end is to stb of the CB & 45 degrees off the wind, quite a distance from the CB (to cover any wind shifts). As boats round 4, their natural line up the beat takes them through the gate/finish line & much closer to the CB than the pin end . This results in boats going round mark 4 & through the finsh line in virtual single file. My recording equipment is a video camera which identifies boats in the general finish area and also has excellent voice recording facilities. So when I call the line, I have a voice record with the piccies attached, in case I miss a boat. I tend to pan the camera right & left & zoom in & out, to cover the area between mark 4 & the finish line. I have now been able to dump my dictaphone. Also if necessary, I sometimes have duplicate recorders taking positions as the boats round mark 4 (just as an extra backup) Finally, use scoring software which does not require you to record fleets/starting goups. Sailwave has an excellent facility where you can set up starts & classes in each start so that all you have to do is input the sail number & SW works out which fleet/start the boat was in & corrects times and/or allocates the correct finishing place. Does this work??? Certainly does! I used it for the SGP (85 mixed class General Handicap) & apart from the odd user input error, all results were spot on each time. Before any SGP people identify that it took a long time for the results, that was another problem which I have now resolved |

Just in case anyone was interested in the software I mentioned above,
with the Time Sheet option, I've now put it back on the web here:
