Re: Wakeboard pulling with AVON S3.40 Help?
Okay. I have to admit that your request for pics and your clamp concept lead me to wonder whether you should be making modifications to your boat on your own. If you aren't comfortable with drilling through your transom, the eyebolt bridle concept is not apparent or you aren't aware of the risks in any towed sport, then maybe you should enlist the assistance of someone with a little more experience. I'm not making fun of you here. Sometimes it is good to get a little hands on guidance. Just a suggestion.
However, I will post two pictures showing the eyebolts with the bridle attached. I still use this set up when pulling tubes. You can see how the bridle clears the outboard.
A release is not required and is not used by many recreational users. However, a release of one kind or another adds a level of safety to towed watersports. They are designed to separate the tow line from the boat if there is excessive strain. Some come with a manual release option. That helps when doing tricks that might result in a wrap (like 360's). Your spotter can release the line before the tension spikes. Here is a link to the Samson Bullet release. The stress pins are a consumable item, but the bullet is relatively inexpensive and installs seamlessly on your tow line. This release will work with a bridle set up since it attaches in the tow line itself.

Here is a link to the Comptech release. It is adjustable and has a manual release function. Very expensive, but reliable. This is what I run with since I use a short pole and I do tricks.

Here is a link to a Cinch Strap release that uses velcro. It has a limited lifespan, there is some fluctuation of the release point if it gets wet and it is a trial and error deal to find your set point (no strain level markings or measurements on the release). Widely used, but also does not work with a bridle.

For just cruising behind your inflatable these are not often used, but I personally like to have some form of release when I'm being towed. My point about the danger of wrapping or hooking the handle was more to highlight the strain that can be applied and the need to permanently install your tow points. Be safe out there!
