Malcolm, Pat, et al

I wonder if you could comment on the sailing ability of a power cat hull (e.g. CS hull form).  There has been much discussion of squatting of a traditional sailing hull that limits powering speed.  

A designer/builder of both power and sail cruising cats once told me that since the force generated by the sails is so far above the water line that sailing hulls needed much more buoyancy forward - and as the force applied by props was along such a different line, that the a motorsailor would always involve a heavy compromise in sailing/powering or both due to the requirements of different hull shapes for sail v power.
