Eliptical pontoons vs round pontoons!

[Bamaman]

I have no idea why they went to round toons. Building round toons takes three sets of welds (2 sections), not including building the nose cones. "W" brackets also have to be welded on the top of the toons. Aluminum sheets also have to be bent/rolled into a cylinder and welded once lengthwise. Round toons appear to be much more time consuming to build, but they may be stronger.

U shaped toons are just bent on a form and welded to a flat aluminum sheet that remains on top. Then the nose cones and rear end caps are added. And they're injected with styrofoam flotation which may add some structure. I believe the aluminum on U toons may slightly thinner.

My 1985 Starcraft with U toons seems to be more buoyant and easier to push than other like size round twin pontoon boats I've been on. The Yamaha 115 hp 2 stroke planes my boat off @ 2800 rpms, and it's a great accelerating boat.

But the nose on new Bennington tritoon lifts @ 30 mph and will run away from my old boat.
