Is there a formula for cataramans

[Steve32]

is there a formula for the size of sponsons you will need on say a 16' and a max of 4 people?

i was thinking of going with a 19 degree deadrise at the stern and tapering to 35 degrees at the bow for each sponson

Steve if you use the forum search, and type "catamaran parameters" you should come up with some info. Or post in multi hulls section.
