We may have the best luck resurecting the original B CLASS , as Mary noted the original B CLASS is no longer in existance and it does seem a resonable approach and one that most catsailors world wide are familiar with .

The A CLASS has undergone many additions and revisions over time to its original basic box rule outline that has resulted in an excellent class with very fast designs of all types , our mission should be much the same .

The B Class was specified as being a maximum of 20 feet long, 10 feet wide and with a sail area of 235 square feet maximum including the mast. The area of the mast being measured as its length multiplied by half the girth.

Here is an excellent link to the T history that developed from the B class .
http://www.aussailing.com.au/tornado/Other/History.htm

Updating the B CLASS rules to include the T and all other existing 20s including the lighter weight newer versions should be outlined . Length and beam are established at 20 L and 10 ft beam , weight and sail area are the other two sides of the box rule to be set . Added top and bottom box rules may also be added as most Formula classes specify in great detail .

opinion > boat weight based on the Marstom 20 weight . 231 LB
LINK --http://www.boatshow.com/M20-Marstrom.html

The Marstom 20 has a 34.5 ft mast height = 10.5 meters
and 22M mainsail in large sq top high aspect shape
= to 236 sq ft main .

The T has roughly = 235 sail area in main and jib
and a 270 sq ft spin .

The T weight is 376 LB that is 145 LB more .

What is the solution to the boat weight to sail area variations to form a class . Main only for lighter weight category then jib area added for those over a certain weight along with larger spin size ?

or another potential equalizing rule of a total boat plus crew weight of 650 lbs which would reqire a min 275 LB Tornado crew weight plus 376 boat weight to = 651 LBs
The Marstom weighing 231 LBs would require a 400 LB crew plus 20 LBs of corrector weights to equal 651 LBs IE

JUST two potential class racing solutions .
