Result!
I've been busy. The RYA has sent me an email today with the now official NHC figures for Swallow Yachts for us to report to duty race officers in our clubs across the land.
BayCruiser 26 0.830
BayCruiser 23 0.815
BayRaider Expedition 0.770
BayRaider 20 0.770
It is important to know that these are 'base' ie starting numbers, they are to be used with the prescribed software that will then change this number dependent upon results submitted - thereby building up a more accurate average over time - the more we race, and submit results the better and more accurate the handicapping will be. So initial discrepancies you may observe will be ironed out. (BR20 and BRe the same?! Really?).
As Graham mentions, the 'smaller' boats (BR's) may race with tanks empty, which actually may have a negative effect as you may win that race on time elapsed and handicap. Submit that result and enjoy the applause, but the next race in heavier wind you will have full tanks, but your new 'adjusted' NHC rating which will then place you further back down the fleet! As always it'll be up to individual skippers to make the call on the day I would imagine.
They have also sent me the calculator (excel) spreadsheet they use to come up with the base numbers but have asked that it is not for public consumption but is for the designer/builders and the class associations to use for new (or not previously reported) boats.
I'll keep a copy on behalf of the association if that is ok with all until we can find a better place to hold it. And of course send it to Matt (and Lara, for safe keeping!).
Graham. I've no idea how the displacement weights are calculated, Matt sent them to me.
I did hear once that there are subtle differences between displacement and true weight, but I heard the words 'fluid mechanics' and 'boolean algebra' mentioned, at which point I repaired to the nearest hostelry. Maybe Dr Peter can help with that one, or ask Matt!
I appreciate not all, probably quite few in fact, are into the more serious racing thing - inded it is new to me (but is addictive!).
But I hope this will be of use to some and I think can only improve our standing against other (and lesser!) sailing classes.
Regards
Andy and Equinox.
