Re: Newbie question, first timer
If you make a turn on either a wakeboard or a waterski, and end up heading towards the boat some, there will be slack in the line. With it connected to the transom it is more likely that the slack will dip into the water (wawa). That can be bad. With the line attached to the tower, you have more time to correct the slack before it goes under simply because it is higher.
I have skied behind a transom mounted tow ring for 25 years and it is perfectly safe as long as the hardware mount is secure itself. I have also had a floor mounted "pylon" pull out, we were lucky no one was hurt. The point is that dangerous is in the mounting, not necessarily the location. This assume that no one EVER sits between the rope and the skier/boarder. That is never safe and you could argue that a transom mount lessens the chance of someone in the boat getting hurt from broken hardware.
