I ask the question how many diferent sized mainsails and jibs will be legal because it seems that there will be a lot, it is quite dificult to get accurately made sails to a specific area.
<br>
<br>we have just made the new f16 sails, they are computer generated, but the computer programmes are just not that accurate at measuring sails the way ISAF do it, so we had to have paper sails made first, then measure these, adjust the programme and cut the proper sails.
<br>
<br>All expensive and time consuming, add to this the fact that the luff of the main will shrink by about 1-2% after its been used a couple of times and I think that you may have dificulty in getting loads of differnt sized sails made. these will then need to be measured by a measurer. the cost will be high and policing it will be hard.
<br>
<br>If somone buys a suit of sails to suit an all up weight of say 700 lbs can they only sell this boat to someone else of the same weight? Of course not, they'll seel 'em to whoever turns up with the cash and that person will expect to be able to race without buying a complete suit of sails.
<br>
<br>I agree with your idea of an all up weight for crew and boat, but I think you need to simplify the weight correction and to have about 3 or 4 maximum bands, I would also leave all the boats with their standard mains and do the correction on jibs, and maybe have 2 spinnaker sizes.
<br>
<br>If you want to keep the 20s a lot faster than the 18s and 16s then you may need to have a separate class within the class.
<br>
<br>You could have standard NA20 based around inter 20 and NA20 turbo or whatever based around an boat that will outperform the 18s etc by about 6 or 7%
<br>
<br>I just think that you are trying to achieve too much in one hit.
