Draft : Draft is taken in “Measurement Condition” with appendages at maximum depth. Daggerboards may retract, rudders may not.
Sail Area : The foresails for the AC72 do not have an explicit area limit. Gennakers on the AC72’s by rule actually have a minimum width, not a maximum, and overall area could be much larger than the lower estimate show here, depending on the ingenuity of each team. With the optional wing extension mounted, the AC45 wing gains about 8 square meters of sail area (see Note 1).
