This is a few years ago and might have just been the build quality of the tower, but it sounds like he did tow tubes?

This tube from tower thing has always bothered me that people say don't do it. It just doesn't make sense to me why you couldn't.
My thoughts exactly.

A tube won't apply a force laterally away from the center of the boat but a wakeboarder can. Hence a wakeboarder can tip the boat.

This can be proven mathematically fairly easily if we make some assumptions but then again it's everyone's boat like I said.

I read the thread and see nothing from the OP that says he pulled a tube. However, I see all kinds of people speculating as to what caused it.

Sorry I call BS on this.

Tube rotating outward has rotational inertia, the acceleration felt by the rider is centripetal force which is paired with reactive centrifugal force which acts upon the tower.

If there was no lateral force on the tower, the tube would continue in a line per Newton's first law.

From a vector standpoint, the tube cannot exert a perpendicular pull to the axis of rotation, but that is not the point, the point is lateral (x/y) force on the tower, and such force is magnified directly by mass

And it's not just lateral force, even if you are just pulling in a direct forward direction, if you've ever slowed and then accelerated a large tube into a wave to catch air, there is a tremendous amount of energy being transferred to accelerate a mass with increasing resistance per the wave. We have a large bungy type rope to absorb some of the "yanking" that can happen. That kind of yanking (sudden deceleration/acceleration forces) are HUGE compared with pulling any kind of skier or wakeboarder.

None of this is to say that MC has not properly engineered the tower and attachment structure to absorb these forces, and again I note that my manual specifically says it's ok, but to argue that pulling a tube is the same or less force than a wakeboarder is to ignore physics.

The question isn't whether or not there is more pressure laterally than centered behind the boat. The question was can you tow from your tower and anyone have any experience.

My answer: Yes you can. I do it all the time. I have never seen a MC tower break from tubing. If anyone can prove me wrong I would like to see it.

I have a 190 and pulling from the tower causes it to cavitate when the tube whips out to the side. Only when I have 2 or three people back there.

I call BS on your BS.

You had better post up some math to support your theories else it's all hogwash!!

It doesn't continue on it's path because there is an outside force effecting it... IE the boat moving forward!!

Tubing ? If you plan on tubing alot , I recommend the Toobstar. The tower/
and boat was made to withstand the pressure. It's a custom order , your dealer can tell you more. Also there are some threads here.

I heard it comes with a mac book air or a HAL 9000 computer system?
