<br> The Formula class is based on the Inter 20 basic specs and existing sail areas , boats are the model for the class.
<br>
<br>-Catagory 2 total weight is based on a 380 min boat weight with average 330 LB crew. 710 LB TOTAL -
<br> If your boat weighs 390 and have a 320 crew wt. it meets Formula rules , crews below this may carry weights , crews above 355 Lb may add additional sail area or not in accordance to total weight to sail area catagory.
<br>All teams are allowed 2 of each sail type approved .
<br>-Note on crew wt and total wt -
<br> A min.wt would only apply to the lightest boat catagory , all others are self correcting .
<br>
<br>- I would like several cat designers and others opinion on accurate sail area to total weight allowances , beyond rating numbers it may require more specific individual boat performance prediction programs designers use having more specific targeted info on crew and boat wt in a 20 ft 8.5 beam design. -
