by CLR and/or CLE.
we sailed an outrigger cat. canoe with a fellow from Hilo.
( Lots of history
, really great guy, and great experience. A "Must do".)
I was amazed by the steering
. Useing only a paddle - Push down to come up - pull up to go down wind
. It was all about changing CLR relative to CLE. That related to wind
surfers, which simply move CLE. So, that leads to the conclusion that balance of CLR to CLE is more important than the rudder
, which adds drag.
form ( width) only relates as it changes CLR at angles of heel. Usually less heal off the wind, so stern width is less relevant than balance. Many hull
forms lack bouyancy forward , so they lift
the stern and "plough" to windward.
