Technically, the volume of a boat has to do with the amount of weight that can be contained therein. If you choose a high volume boat and don't normally carry something within the designed load-range the boat will sit up on the water like a cork and the high center of gravity will make it more tippy than it should be.
For stabilty the hull has to be pressed down into the water to try and get the C/G close to the waterline as is practical. You can go shorter and wider but the weight of you and your gear determine what amount of displacenment a prospective boat should have not your linear measurments.
I have family in Bayfield County. I only paddled there twice. Off Squaw Bay/Meyer's Beach,and in the bay off Washburn but the Meyers Beach paddle was nicest big-water paddle I ever did.
