Share 'Increasing Pahi 31 by 10%'

I am looking at maybe building a Pahi 31, I would like to know if somone increase the dimension by 10%? Basically I want to increase all the dimension of the boat by 10% to make just a little bigger execpt the overall beam of 16 foot that i would like to keep the same. I understand that by doing thus will increase the displacement by 33%. Anybody have an opinion?
