chcliffb, I do not want to spin your head around again, but a while back I had a tow hook point issue as I had installed a ladder on top of my platform and the rope would have caught the ladder when hooked to the center tow hook. I looked around for short pylons and found this gizmo on ebay...:
The top of the transom on my boat was perfect for the install of this, and it works great.
Here is a pic of it on my boat, small chrome cap looking thing top center of the stern...:
Here is a video of how it works...:

There are plenty of these still available on ebay, for some reason the prices vary wildly.
If your boat has the right config at the back this may be an option worth looking into.
