Overloading a tower with too much weight?
 
I've been reading old and some current posts about towers flexing (and even breaking) and it has me wondering, is there a point where there is too much weight on a tower?

I have a 2007 X14 which I believe has a ZFT3. We often roll with 4 boards in the rack and I have speakers and two smaller lights on the tower plus bimini. We have the braces Mastercraft provided. I recently added a ski rack above one of the wakeboard racks.

While hitting some chop recently my daughter commented that the rack had quite a bit of wobble in it. So the question for the collective: is there a limit of too much weight in terms of boards, speakers, lights and such that is too much for a 2007 ZFT3 rack?

I think you will be fine, but do you have those stiffing add-on braces?

DOH, just read where you say already have them.

I think it's a good idea to check the knobs to make sure they are tight as well as checking the hull mounting points a couple of times a year.

I say BE careful. I had a 07 x15, and broke the tower right at one of the welds next to the bow light. Weld that is covered by the weld collar. Was it just a bad weld (dirty weld, for those in the know) or was it we use to travel in pretty good chop at 30+ mph with four boards on the rack, I don't know, but don't want to find out again.

Personally I wouldn't worry too much considering the weight you mention. I am probably easily double the weight on my tower and have had no issues in the last three years. I did have to weld in an additional cross member to accommodate the foil racks, but the tower itself is still holding up just fine. This includes busting big chop down in Powell with the rack loaded up. IMO, I think you are okay.

If I can't put all that stuff on a tower I don't really need a tower!
It's fine just notthe stiffest tower out there.

You will get some wobble anyway as the most of the fixings are ball joints onto the boat?

All structures deflect to some amount, as long as the deflection doesn't cause fatigue cracking, overload a joint or the additional mass changes the natural frequency of the tower to somewhere in the region of the applied frequency of vibration then it'll be fine.

We love it so far. It is a real head turner, especially on the water.

Also thanks for the pointers from the other responders. With two kids and myself that ride everything possible (except surfing, but that is going to get mastered next) it is hard to find enough space to store gear. When we used to use our JetSki for pulling we would cover our friend's dock with gear of every shape and kind.
