There is one advantage of canting the hulls that was not mentioned here: if you cant the hulls and keep the same crossbeams, the total beam will increase and so the max. righting moment.
Or, if you cant the hulls and keep the same overall beam, the crossbeams can be made lighter.

Yup, and another I do not
think has been mentioned is that the lee side of the lee hull is more vertical so producing less of a wave / vortex - whick looks great and is very usefull for filling up slower boats as you pass, but must be slow chucking all that h20 out !
