Too bad you don't have a legitimate North American Class Association to sort things like this out.
Good point. The international class will not jump in to solve such a local issue. I was under the impression that various sailors were forming such a local US class association. Alot of fuss was made about such a thing only a few months ago.
But even without such an association I think this "problem" is easily solved. Just notify the Race committee that you guys are all racing of the fastest handicap (either the sloop or uni handicap, whichever is the fastest) and just do it.
The F16 class rules are clear enough on this point. No minimum crew weight and no obligation to use a full set of sails.
They even explicitly mention both the doublehanded and singlehanded use.
I think we are CREATING a problem over actually having a problem here. There is nothing and nobody preventing us from racing both setups as first in wins. No class rules, not the international organisation and certain not the Race committees in question. In reality the only party that can put a cross through it all are the individual owners. If they decided they want to take their chances with a marginally slower handicap then there is not much you can do. But this is, as Darryll mentioned, an internal family (class) matter. And also not one that any association can solve, the association is not going to force anybody to sail in a way they don't want to.
In a one hour race at an average of ten miles per hour, a boat travels 52,800 feet.
And how many inches is that ?
It is also silly to look at this problem in units of lengths. For example if your boatspeed is only 5 miles per hour than suddenly your distance disadvantage is halved !
It is better to look at it from a time perspective. On the assumption that the US D-PN is right ! (A hugely important assumption, because other rating systems do not agree with it). The time difference between both makes after being a full hour on the race course is 60 seconds (1 minute) with (in this case) the sloops being rated as faster.
I challenge anybody to finish within a minute of the leader after an hours worth of racing in any condition. You will actually find that this a VERY narrow window to hit after an hour of racing, that is if you are even close to the leader to begin with. You will very often find that you are either the leader yourself or you are more than a minute behind.
While doing this test please also note how far in front the leader is (you are). You will find that even a 60 second gap will appear to be only a very short gap. A minute under the shower may seem like a long time, a minute on a catamaran race course isn't. Hell, alot of sailors have trouble crossing the start-line within a minute of the signal.
So the net effect of this handicap difference in the final standings is in most cases zilch.
Now some sailors feel that even a single second is a noticeable or even significant difference, they won't accept any difference between rating numbers even as small as 0.1 point. But of course by vitue of the way D-pn ratings are created we will never have equal rating numbers for both setups. Hell, if we would create 2 seperate D-pn's for the sloop version after splitting the available race data through the middle then we would see a larger rating swing then that. Even when both data groups are taken from exactly the same boat and setup. This is a natural occuring statistical phenomenon.
I dare wager that a large portion of the difference between the two setups is caused by the fact that two different groupings of data were used to create either rating. I refer to my example of throwing a true dice. Even if the dice is true you can't expect to hit the theoretical average when actually throwing it 10 times and taking the average. And more importantly, you can't even expect to hit the SAME average as the first time when throwing the dice another 10 times. In the same way the D-PN handicap numbers work. The fact that they are so close to one another is actually statistically supportive of the two setups actually being equal performant around the course. But I won't tire you with the calculations in this case.
An advantage of 1.7% equals 1 minute or 898 feet.
That is 56, 16' boat lengths.
That is not a negligible (neglectable ) difference.
A minute is a minute, the usage of distances is just confusing as they are fully dependent on the ASSUMED average speed.
The rest is just a personal weighing of the what a minute on the water is.
I for one couldn't care less about such a theoretical minute especially not since my fellow American F16 sailors are already sailing off a handicap that is 4.5 % (161 sec = almost 3 minutes) slower than what I race off overhere. (I race off the F18 rating = 62.5 in the US D-PN).
You can all look up my results and I'm not doing any worse than the US sailors. Gary in Australia is sailing of a rating similary faster than ANY US D-PN and he is doing the best of us all. John Alani in the UK is singlehanding of a rating no less than 8.5 % faster than the US sailors and even he is reporting to do just fine. That is how little 1 or 2 % rating number difference matters on the actual race course.
In nearly all races, a 60 minute extra hit or benefit PER HOUR racing (=only 30 seconds or so in typical bouy race)won't raise or drop a crew more than 1 place in a 20 boat scoring fleet. In about halve of the races it will place them at exactly the same placing as without such a extra hit or benefit.
That is the reason why I call a 60 sec/hour difference (1.7 %) in the HANDICAPPED performance neglectable (or negligible)
You just have to hit the line right on time, look for clean air, sail fast and not make (m)any mistakes. This is a FAR greater challenge then most sailors think and that is why most sailors don't come within a minute of the leader in the final results. It's these things that make or break your race and having a 1 or 2 % benefit in handicap number doesn't make these things any easier.
