-Given the set of existing circumstances and numerous existing 20 active racing designs believe this sail area to weight rule is the best solution to include and equalize the av performance of them and allow new lightweight designs to evolve.
<br>-It will require all designs to modify and upgrade to slightly larger sailplans as the scale is applied to existing designs.
<br>
<br>Proposed preliminary sail area to boat weight ratio scale for the 20 class -
<br>
<br>max, Weight -420 --main 220 --jib --60 --spin 330 sq ft
<br>
<br>-mid range -Weight 370 --main 200 --jib 55 --spin 300
<br>
<br>-min Weight 320 --main 180 jib 50 --spin 270
<br>
<br>-note; shown are max,-mid and min. --all would be calculated based on individual boat weight and fall within this range .
<br>
<br>-Again -these are preliminary proposed numbers , and expect some revision before finalizing them ,but wanted to demonstrate how easily this can be achieved rather than explaining in the abstract as previously .
<br>
<br>-As you can see we are proposing an increase of sail area of the existing N-6/0 for example at max 420 lbs. from exs. 264 to 280 max , main and jib ,--including mast area .
<br>-Max. spin area would be 330 sq ft . with a percentage allowance in increased spin area for alum , and heavier masts with added stays or the heavier comptip of several existing designs wishing to keep them rather than modify .
<br>
<br>-Stay hound tang mast locations and max height can be standardized along with max spin pole L .
<br>
<br>-All designs would also be allowed to shift sail area from main to jib in total equal sq ft per weight catagory,allowing some flexability in design . In the mid range weight the 8.5 beam version Tornado at 370 +or - could use its existing sailplan main and 75 sq ft jib with larger allowed spin if desired.
<br>-At the min weight end we are encouraging approx 100 lb lighter designs than existing F-20s with slightly smaller main and jib with equal spin area in respect to current boats.
<br>
<br>-Once this difficult aspect of the rules is discussed revised and finalized keeping in mind the goal of equal fair sailing , the other rules can be simplified .
<br>--Please review specs as applied to your particular cat and please post with constructive comment .
<br> Thanks
