I built it, I paddle it, I loved it....but

I am too big for it. I added a few extra inches when building, a little more height for toes, i stretch before going out, but I just can't do it. She rolls like a dream, tracks without weathercocking, shes fast, nimble, a blast in the waves, and a joy.

I wonder how to make the next size up for 6'2" and size 12 feet without compromising what seems so promising. I get in and my legs and feet are locked into one position with no way to stretch out or change positions leading to cramps and sleeping feet. I would like the same boat only bigger without that odd hump on the deck or sawing off my feet.

Any suggestions
