ive finally decide to cut up an old 1648 and build it the way it shouldve been built. .125 floor. and make it 60" wide. anyway, ive never owned a slick bottom or a tunnel hull only had pods on jons. when i get it built I am gonna though on a 40hp 4stk yamaha tiller. planning on pods either way but should i tunnel it? i love to runing the rivers but i dont want to sacrifice inches in the shallows where displacement and weight are big factors. whats you best argument?
