Hi John ,
<br>
<br> Please excuse all the infighting here , different diverse customs ,--We do all actually sail and race and have a good time .
<br>--It is open , the total boat and crew weight to sail area scale would ideally be in increments small enough to be fair ,--maybe as low as 10 LB between each ,--or as high as 30 for more simplisity. -
<br> You are more qualified than I also to establish the amount of sail area of each main -jib and spin .
<br> tryed 1-jib 3 main and 10 spin per each 10 Lbs of total boat and crew weight. as an example , believe this is close based on existing designs but need to be revised and corrected to ISAF rating numbers consistant for a class .
<br>
<br> I do not believe it is enough just to have them rate to an ISAF or Texel number as we are setting higher crew weights generally , and more sail area ,based on the U S version Inter 20 ,-which has 15 more sq ft of main sail area . --
<br> Believe they should rate within one point . -but may also run an individual performance prediction of the specific boats with various crew weights at each end of the scale .
<br> Was hopping for a total range from max 410 boat weights down to 320 ,-again in 10 20 or 30 increments ,--using an average 330 LB crew .
<br>
<br>-I design homes, extentions , and small commercial buildings , but am not a navel architect , we do really need someone with your expertise to advise and direct .
<br>
<br>--Thankyou John
<br>-Carl Roberts
