"Constant Camber" is a boatbuilding technique developed by Dick Newick and
Jim Brown for making sections of multihull hulls in an efficient way. In
it, there is a single standard mold, having a compound shape of constant
camber on which cold-molded panels of several layers of veneer were laid up
with epoxy. Several of these panels would be joined into a trimaran or
catamaran hull. This technique had the advantage of only requiring one mold
to be built, but required that the panels be 'tortured' into the desired
hull shape. Ultimately, the evolution of multihull hulls to have less
rocker and the emergence of strip planking methods, structural foams and
sandwich construction have eliminated its use. Kurt Hughes' "cylinder
molding" is the last gasp of the idea.

I've seen the phrase applied to boathulls, especially catamarans.
Seeking edification. Thanks.
