Re: dumb Question but need to know
Using eye bolts that are installed low on the transom will work, but you need to make sure that they are strong enough for this application. If the eyebolt head is just a bent section it really isn't sufficient. If the eyebolt is a forged one piece with a large washer or backing plate installed inside the boat it will work fine. Remember the trailer straps are pulling down at an angle almost perpendicular to the bolt installation. Towing will pull almost straight back. You need large washers or backing plates on your tow eyes. Tubes and inflatables will run fine on the low tow attachment, but you may find it very difficult to start on a ski, wakeboard or hydrofoil. Attaching your tow bridal to forged eyebolts placed higher on the transom makes it much easier to water start (that small change in angle helps a lot).
Even loading up on a slack line should not bend the supports on a properly installed pole. The support may have been dented, bent previously or subjected to excessive loads (multiple people in a tube). A properly installed short pole is a great option and mine has withstood riders crashing while throwing inverted tricks on hydrofoils. You might want to replace the pole.
