Jimmy skiff resizing

Posted by Éric on May 25, 2006

Hi boatbuilders, I would like to build a Jimmy skiff for family sailing on the Great lakes. But the boat seems to small for my wife, two big teen ager and I. So I would like to know if it is possible to make the boat bigger by multiplying all mesures by 10% and if that can apply for the sail area ? A future sailor Éric
