RE: Monk 36 Rudder

Is there anyone who can explain whether twins require the same or less rudder area as a single?
I would expect them to require less, as the full amount of rudder required should be related to the speed and hull configuration of the boat, rather than the number of pieces it is divided into. So maybe not a linear relationship, but if a single requires for example, 6 sq ft of rudder to achieve performance at hull speed, twins may also require 2 @ 3 sq ft, and if you were to put in a third engine, 3 @ 2 sq ft.
so Woody's rudders should be a lot smaller than Tony's.
sorry Woody.
