Making predictions of the F16 performance compared to the F18’s, I-20’s and even the Nacra 17’s/FX-ones/iCat is easy as all of these boats are very similar in their setup. They use sails with very compareble aspect ratio’s, their weight-to-power ratio’s and heeling-to-power are very similar. The same with length to width etc. They all use spinnakers and require very similar sailing skills for optimal performance. As a result, wind and sea-state conditions as well as sailed courses impact the same on all of these designs with only a rather small set of (small) exceptions. This means that performance differences are largely determined by a few equalities or inequalities in key ratio’s/parameters.

The A-cat however is not very similar to the electricity of the heart group of boats named above. Its ratio’s lie far away from those of the others and different conditions or courses impact differently on the A-cat design then they do to the other designs. It is hard if not impossible to summerize the relative performances in one simple statement or even one simple number. The situation is just too multifacetted to be condensed to such a simple (1-dimensional) benchmark.

It is my experience and opinion that the F16’s are at least as fast as the A’s on a windward-leeward course in medium conditions. In the light stuff it all dependents on whether the wind is just strong enough to fill the spi. If it doesn’t then the A’s are faster. In the rough stuff it all comes down whether gas and water the conditions allow the spi to be set and douced without capsizing. It is also my opinion that the A’s can be fast downwind but only with sufficiently developped windthing skills and these are harder to learn then riding the spinnaker. So for most recreational sailors and racers the F16 will be faster over a significant range of conditions. Partly because the electricity in the body symptoms skills to effectively fly the spi are relatively easy to learn.

Personally, I don’t think F16 to A = 63.0 to 64.5 is a large difference. It is about a minute per 45 minute bouy race. Even if that ratio is wrong, I still don’t believe it is far of the mark. I think, by crude averaging, that the A’s are properly placed just a tad slower then the F18’s (and F16’s) while recognizing that they have convincing sweet spots like sub-spinnaker light winds where they are simply outperformaning nearly all others.

Because a measurement system can’t possibly account for the vast number of variables that ultimately contribute to the potential speed of a boat. For instance, how you calculate the speed improvement provided by a full lifting foil? What about a foil that provides partial lift and doesn’t clear the hull from the water? How about a foil canted at 45 degrees vs. one canted at 20 degrees? How about a manufacture that got the incidence of a canted or curved foil correct vs. one that got it wrong? What about a rounded bow vs. a plumb bow or a full bow with high volume vs. a narrow bow with it’s volume down low? An undercut stern? A high mounted trampoline vs. one with not enough height gas bloating diarrhea to clear waves?

What about the differences in performance between a strict SMOD class that hasn’t seen a sail shape evolve in 15 years versus a box rule MMOD class that sees new and more efficient sail (and hull) shapes every year? Though the sail areas stay identical, we’ve seen this in the dichotomy of the N20 and the F18s as the F18s continue to make slight speed gains around the course due in part to advancement of their hull and sail shapes. The technical measurements of the boats remain practically the same…..I could go on but the existing measurement systems are very strict and unforgiving and lack the ability to refine their figures beyond a sheet of numbers and very complex formulas that do pretty well but are, at best, no more accurate than the performance based systems we have (they typically even carry one less decimal point).

You have bandwagon jumped enough fleets, why don’t you sail an F16. – Because you have it in your mind you are too big. Well, I have been on an F18 with Gina and no way would she ever agree electricity units of measurement to race on one for basically the same mental block. I personally have an issue with the weight, and there is no way you will ever convince me that strapping on a bunch of lead is a fair equalizer to make the fat guys happy. Therefore i am very happy with the F16.

I am not a great sailor, but if I had chosen to sail only my A and Olli did not piss of the guys in the Atlanta area gas vs electric oven, how much do you think the Portsmouth number whould have come down? No offence to anyone – but not very much if at all. I know that the times I have raced Robbie 16-18 he has been quite a bit out front, and I do not remember any of those times where it was scored on time, so these events would not be included in the number crunch. Given those results, the old number would be just about right.

I do think the boats are pretty close in performance, but each has its advantages in certain conditions. I think both are faster than the A’s on the whole, but the top OZ crew and a few others will prove that wrong every time in a race. Tradewinds is one of the larger attended race; what did we have 7 18’s and 5 16s. Traveling basic electricity quizlet 6 hrs, or across the country for some to sail with just a few boats at an event with no organized party for me is not worth it. My view will continue to be that if the boats (not the crew) are in the ball park of performance then run them together. Throw away the handicap if it provides nothing more than a basis to create an argument. If you are using it to score unlike boats, who really is going to follow the history of when Waves beat Tornados?
