i am thinking 23' at min and 28' at max, open bow, would love to stay with a tunnel but depends on the boat, needs to be kid friendly ( i will have 2), something i can leave in the water over night, and run more than upriver once on a tank of gas........and as i have said before, i love your boat, i have always liked the silhouttes and said i would have one one day, when the time comes, we will talk if you still have it
