sagging in the rear

[alilley]

ok me and dad was b sing one night about pontoons and how they always seem to sit lower in the rear. We understand that the motor is litteraly hanging off of the rear which causing this issue. My question is y couldn't the designers make the toons a little bigger in the rear to help compainsate for the extra weight of the motor? I do know that they cand "nail" down what every motor is going to weigh as there is so many differant combinations out there, but something is better then nothin.............this is just something that i have been courious about and figured i would try here first many thanks

Re: sagging in the rear

There is a limit to how wide a pontoon can be and still be legal to tow. That width is currently 8 ft - 6 in. Making the tubes bigger in the rear means the width would have to be added toward the center of the boat. This does two things. 1) It creates drag because the flaired out tube acts like a wing in the water. It also narrows the gap between the two tubes making the motor run in even more turbulent water. If you look at the seating and furniture arrangements on most pontoons, the weight is almost always concentrated at or behind the the horizontal centerline of the boat. That causes the stern-low appearance. Any boat generally sits lower in the stern regardless of its shape. That's where the weight it.

only other thing i have in reguards to this is......i understand the added grag that would be caused but, if the toons were wider tward the center, when under away wouldnt that "lift"the stern of the toon even higher in turn creating less drag?and allowing the toon to sit leval?

Think about what you're saying. I don't want my toon level. A level pontoon boat will plow when she's under way, which will result in lower speed, a wetter ride, and increased fuel consumption. When I pull my daughter on her tube only the uninitiated or those who want to be splashed sit up front.

I think all boats squat at the stern.I think the true percentage of squat in relation to hull size
is close over most boat styles.But on a pontoon you have a nice straight hull side to evaluate the amount of squat. it becomes very obvious.

Yet another case for a tri-toon!

Also if you make the boat sit level at rest it will cause a alot of problems at speed not to mention they would be harder to build and more expensive.

The boat is too heavy and long to ride on the back of the tubes, they don't plne like a conventional hull and I think if anything it would push the bow into the water.

Aquadynamics is a very funny thing, what you think will work never does and the stuff you don't give a chance works really well.

Re: sagging in the rear

Would not just making the toon longer in back be a better solution

Re: sagging in the rear

The manufactors could put the motor in the center of the boat.An advantage would be ,you could turn on a dime
