The biggest advantage I see with a Pontoon stability while allowing comfort in moving around when you have the family on board. (more than two people) The disadvantage is that you are off the water(like pear fishing) and it is like a sail when the wind blows. If my grandkids lived near me I would have a pontoon.
I rented a 22ft pontoon boat, took 3 adults and 4 grandchildren we had a great time. Some fished and others wanted to swim, I guess if I get a pontoon it will provide entertainment other than just fishing. Something on the plus side that I hadn't thought of before. Anyway you all have given me a lot of helpful information and I thank everyone. Any more thoughts will be appreciated.
