Just to add to what Martin Searle has said our aim at Seasalter is to let everyone sail what and how they want according to the conditions (but only one class of boat in any series). The RO credo being all those sailing are there to enjoy themselves so let them decide how they want to do it.
To that end we split races into 2 fleets (950 PY). So all our Sprint 15s race with Dart 18, 505, Hurricane etc. Because of this our ROs always record individual times,laps and finish(except in pursuit races where position on the water at end time is all that is needed)and position is based on handicap. If you go out solo with a jib rigged on the forestay you get 882 PY whether you use the jib or not.
Some people have used both modes in the same series and I have to keep on eye on that when doing results (using the race specific rating facility in Sailwave)but again I see little advantage gained.
In fact it is the heavier helms that tend to use Sport mode as they can handle the boat better with the extra sail area and I suspect that this makes it fairer overall when you look at light wind performance of light helms.
Our Sprint 15 helms range in weight from about 8 stone to 15 stone but skill appears to predominate in most conditions with Sport mode not having a great bearing on results over the last few years.
I am not particularly convinced about 916 PY for a 15 with two up - it appears that this will only really reflect things correctly if the combined weight is less then 15-16 stone - all junior crew of 1-5 stone welcome!!!!
All our sailing is on the sea and that might have some bearing.
One interesting variation is that one of our Dart18s has a Gennaker and it seems the advantage gained on a run is lost in the time taken to recover and stow it each lap. I give them the same handicap as the other 18s and that boat/crew seem to do better without it and I think they spend more time with it rigged in the field playing with ropes than with it up on the water. A photo of them at speed on 6084 without the Gennaker is in the racing action page of pictures on our web site
www.seasaltersailing.org.uk along with a number of our Sprint 15s in both modes.
Bottom line for us is that I could not define Sport mode or not for our races as it would either put off or not permit people to sail in some events. Anyway I have enough trouble with sorting out the slow handicap fleet with PYs ranging from 973 to 1386 all going together!
