Anyone know alot about the Crowther Cat haul designs

He has made some were the hull design is a
full displacement hull with bow balls on the pontoons and 2 fixed fin keels
aft.
Has anyone seen one of his Sportfishing 50 ft models and how they ride?

And heres some stuff I got form Stuart Bloomfield who has sort of taken the reigns of Locks designs

It goes over Locks design thoughts on multihulls and was the front few pages of his design catalogue.
