Hi Laurence

An IRC5 class of only 18 boats with a split of 19 IRC points could make for amazing racing!

Trust you can do it!

That's the plan so far Bob! Let's hope for 16 knots of breeze and this continuing sunshine!!

In the draft split for IRC 5 posted last week we had an IRC5 class of only 18 boats with a split of 19 IRC points could make for amazing racing!

And today it all changed, for the much worse. CWL announced an IRC Class 5 of 25 bpats with a range of 35 IRC points.

Somebody must be happy but it wont be the J97's or J92s racing against bigger faster boats in solent tides.

This is even worse than 2017;

Hi Bob

We have to take a decision and there were two options for the splits. Clearly we went with the one you don't like and I'm sorry about that of course but I think what we have done is the best bearing in mind the two options we had. More classes are better structured this way even if it seems Class 5 doesn't meet with your approval.

I have had a suggestion that we look at doing a "J Sprit Class" for 2019 and happy to see if we can make that work if people think it would be better racing.

Best regards,

Laurence

Hi Laurence

Yes, you could run a "J Sprit" class next year, and it would reduce the uncertainty about racing quality for those boat in it compared to what happens now with five days notice.

But that does not address the fundamental problem of IRC Racing in CW which is "too many boats in the middle IRC classes". Between 21 (IRC3) and 25 (IRC5) boats per class, an average of 23. In turn this forces too wide rating bands and seems disproportionate when you look at all the OD classes with 8 or 9 entries. If you resourced one or two extra classes in the mid IRC area that would allow 18 or 15 boats per class and provide better racing.
Is it not possible to add an extra IRC class for 2018?
best regards Bob

Hi Bob,

Yes we can look at more IRC classes possibly for 2019. I'm afraid that its too late for this year as the changes would require wholesale upheaval of the SI's, starting sequences etc. and that's not viable at this stage.

We generally aim for 23 boats as an average. Interesting you think that's too many! We think that's a good fleet size for a regatta and we try to look for a maximum of 50 rating points variance. That's 3 minutes an hour so a 9-minute spread in a 3-hour race. That seems like a good target that delivers good racing but of course the tighter the range the better. It's not one-design but within the constraints of the handicap class entries it's pretty good.

I'm happy to look at options for 2019. More IRC classes perhaps or some "special classes" for other similar boats.

Best regards,

Laurence

Hi Laurence;

Yes I realise that it is much harder to add class starts than to remove them in an event as complex and CowesWeek!

But it is interesting when you say "We think that's (23) a "good" fleet size for a regatta and we try to look for a maximum of 50 rating points variance..".

I would not say 23 entries/50 IRC points is "good". Words like "acceptable" or "unavoidable" come to mind for Solent tides and courses.

If I look back to last year's IRC5 results, the three top boats were all at the top of the rating band and that's what happens very often. Not always - some boats like "Yes" and "Haven Enigma" are exceptionally well crewed and often win whatever.

But normally in a big fleet with a wide rating band the boats with the lower rating are going to struggle to do well. This is born out by experience and one can see this in CW's results archive. It is also worse for the slower boat as the tide has a greater impact.

With so many entries CW does have a rare opportunity to improve on this. Hence my plea for more IRC classes next year and some notification of this in the NoR.
thanks Bob

I hear you Bob and something we can look again at for next year. The problems is that our start sequence is already 2.5 hours long and we want to shorten that if possible so we are more flexible. That said, we want great racing so lets see what we can do.

I may catch you in the week to chat further.

Best regards,

Laurence

Hi Laurence

A radical suggestion to significantly shorten the start sequence. Switch to warning signals every 6 minutes instead of the current 10 minute intervals between starts.
This would reduce the current sequence by about an hour and allow plenty of scope to add further classes.
It would also please those classes at the back of the queue who don't get to start their race until around midday or much later if there is a postponement.
