See for some scientific foundation the analysis performed on REAL race data (Nationals) if you follow this link :
http://www.geocities.com/f16hpclass/F16HP_optimal_crew_weight_analysis.htmlBy the way 140 kg is the centre of the optimal weight range running from about 125 kg to 155kg.
For US sailors : centre = 310 lbs. The range runs from 274 to 342 lbs.
Naturally the boats will carry more weight but in a less comptitive sense. This range seems to be pretty unbiased over a range of sailing conditions. Actually we all know that weight only really plays a role in the range from 5 to 12 knots. The F16 is pretty power-up in this windrange. Just as powered-up as the F18's as a matter of fact. The direct result of this is that you don't want to be too light when sailing an F16, despite all the gut feelings you may have in contradiction to the science.
For the guys who fall asleep as soon as they see or hear the word science I have another explanation. I'm racing at 145 kg combined crewweight (320 lbs) and I'm finishing in the upper halve of F18 fleets ON ELAPSED TIME ! And I'm depowering that rig as soon as I hit 10 knots. Just last sunday (between two heats of our club race series) I took a 83 kg guy along on my boat for a short ride (he jumped ship from his own F18) under a mainsail alone in 10-12 knots of wind. I'm 82 kg myself = 165 kg on board = 360 lbs ! And he was fully trapping with me hanging overboard when going upwind at speed. That was just with the mainsail ! Guy was yelling :"gee mate, what a boat, never expected this"
We must also not forget that our advertised competitive weight range is only 30 kg (66 lbs) wide (from 125 kg to 155 kg) compared to the 65 kg weight range (115 kg to 180 kg) advertised for the F18's (= 144 lbs). We don't need a system to level the performance of the boat like the F18's have, our target range is already narrow enough to be fair using the same gear. I would even venture to say that we are more fair then the F18's with the performance equalisation system, but you may classify that as my personal opinion.
Unless the class can do something to level the field for the bigger teams I don't see it gaining the same kind of acceptance as the F18.
This is actually of no concern what so ever. The only thing that is of concern is the ingrained believe that short boats are slow and only suited for very small and light people. Time and time again I find that I need take sceptics along for a ride in order to convince them. No amount of "talk" has ever had the same effect. The gut feeling always seems to win out over the science. It is just how people are. No offense to you Ding !
Mind you, often it only takes 2 minutes of F16 sailing in 10 to 15 knots to have the sceptics do a 180.
Now I'm certainly not saying that F16 is the class for everybody. It certainly is not. But any crew weighting between 125 kg and 155 kg and looking to race hard will do well to consider the F16's. Crews from the larger weight range of 110 kg to 170 kg will have good fun sailing or racing these boat recreationally. You'll be surprised how quick these boat can be with 170 kg on them. Hell, I raced a Stealth F16 at 165 kg (with Bard) during the Spring Cup series 2005 in a fleet of over 30 F18's and finished in the upper halve of the final score on elasped time !
All races were in 5 to 12 knots of wind, the range you guys seem to consider the death zone for 165 kg (= 365 lbs) crews on a F18 ! We were doing it at this weight on an even smaller boat with smaller sails ! And we weren't that good as a crew (Bard and I) as we had never sailed together before.
No Dave, the problem (if any exists) is not the lack of any system that addresses the fears of the "heavier" sailors, but the perception most people still have of the F16's. You know, the kiddies boat syndrome !
Ohh by the way. Over here in Europe 155 kg (= 340 lbs) is considered the ultimate weight for the F18's
Fair winds to you all !
