People do it all the time. particularly down south. It seems especially popular to tackle, when you are going to be doing a full floor replacement.

If you have a pontoon, that is paid for and everything is in good shape, it is likely a good solution, if you want better performance, or cargo capacity with out going out and buying something newer....

I myself may consider this in a year or two... I bought a reasonable priced 20 year old toon, to see how much I liked it... With the idea, that I could make updates to it, over time, and still not spend as much as I would have to by something newer. As I still also have speed boat, going to a tri-toon is not my first thought.... But I am going to be looking for a bigger power plant over this winter...... I tend to run the current motor, to high in the power band for my taste.... and well its a 20 year old motor, so who knows how much life it has left in it....

Do you think it's as simple as adding a third toon? Looking at the designs underneath, I don't think you can just slap a third one on—even the only-a-couple-year-older Harris designs are different than my '16...

I changed the pontoons on a boat I had. It started with 19 inch diameter pontoons and I bought Bennington elliptical pontoons. I think they are 24 X 34. It made a huge difference in ride and draft.

I learned a couple of things. The structural integrity is the pontoons themselves. The brackets will most likely not line up with the ribs under the boat unless you buy the exact same brand, and even that is not a guarantee.

I mounted 2 inch aluminum angle on the entire length of the new pontoon brackets and then drilled where the existing cross members were on the boat to install bolts. That is what I think you would have to do when adding a third pontoon.
