Are you trying to calculate the hull surface SF. Or maximum SF of the boat when viewed from the stern. Or some other surface? Or a combination of surfaces? Due to some very curvy areas it is a very difficult task that is dependant on hull shape. Hand calculation is a approximate answer at best.

Short of cutting pieces of paper and taping them on the hull I have no idea of the accuracy by the non-use of some exotic cad cam tracer program.

I gave my old slide rule away years ago. That was a real hand job calculator. I have a few hulls that could keep some one busy.

Google "Simpson's rules", About half a hundred ways to get exactly what you want. If you really want to get cool use one of Tchebycheff's rules.
