How is the NHC base rating modified for Non Spinnaker etc? have tried googling etc and struggle to see how to amend our base number
Sorry if this is a daft question, but we may enter a club race and I though I had better look at this
The other boats are IRC with spinnakers :eek:
Thanks

Don't know about NHC.

But the reduction in rating for non-spinnaker boats under IRC is pretty minimal. If you're going to be racing against other boats with spinnakers (and it's not an uphill all the way coastal/offshore race) just go with the spinnaker yourself.

It isnt. Thats one of the failings of NHC as set up. The assumption is that in a race series, the race by race handicap adjustment takes care of such minor issues as prop type and twin vs fin keel and spinny / no spinny.

However in a club the RYA edict isnt law. If your club wants to use the old PY adjustments they are free to do so. Indeed they are free to use PY in total.

Thanks for the replies. So no way way of handicapping a one off race using NHC

Its not designed for that any more than PY was - its designed to take into account crew capability as well as boat. With NHC, if you race in two series, your boat has a different handicap in each series because you are racing against different competitors. And that means you cant "transfer" your NHC rating from one series to the next one and have to start each series with the base number. It means that a fleet of 7 identical Sigma 33s would have 7 different handicap numbers after just race 1 of a series.

PY, which in principle is just the reciprocal of the NHC number multiplies up a bit, could have been operated the same way but wasnt because in theory every club racing sent all their results back to the RYA who then compiled and averaged then into a handicap number for every type of boat raced. There are problems with that system too, but the worst one was that clubs were lazy and simply didnt send the results in. In its final years it was something like 7 or 8 clubs in the whole of the UK sending in race results.

If you are a standard fin keeler, something like a Sigma, then you can use the base NHC number for a single race and it will be close. Within your club ie not for open meetings, there is nothing to stop you using the old PY adjustments on the NHC numbers. For example, with no spinny on a boat rated to include a spinny, you deduct 4%. If you pm me your email I will send you a copy of the old PY adjustments.
