hmmmmmm well thats my plan original plan stuffed, however me being me has a solution.

You could fix two eyes to your deck then run a bridle over the transom and around the engine. this would keep the bridle out the water, and give you extra advantage of a fixing point for luggage. it would look something like my drawing ( which isn't the best)

this should work.

humz interesting... so by putting to new eyes in above transom, it's effectively raising the whole thingie...

will give it some thought and stare at my boat a bit more..!

cheers!

I'm probably going to regret starting this without the aid of a diagram.......

If I'm reading this right, you just want to reduce the slack - tension of the tow line when bouncing over waves? Bungee will stretch a certain percentage of it's overall length for a given load, so, if you have a long bungee tied (say) halfway along your towrope, for a given extension of it you'll need less force to extend it, therfore reducing the load on the a- frame. Alternatively you could tie it to another bridle at transom level, which will reduce the bending load.

The fun bit ids going to be setting it up so that it takes enough slack up without ripping the frame off the transom....... Could also add a short length of thick- ish bungee to the tow line itself to prevent "snaps"? (although if you get that wrong, it could be amusing to watch! )

I thought he just wanted to get the towrope up higher to avoid the wake. Assuming I was correct about that:

How about dropping a loop of line from the upper corners of the A-Frame, and running the towrope through a pulley attached to the low point?

Should keep most of the force pulling down on the tower, rather than back, and you can adjust the height by adjusting the length of the loop.

attaching ropes to the a frame is a real bad idea cause it will either bend out to shape or snap off.

Hence the suggestion to alter the direction of the force applied...

Errrr it looks like 2" stainless tube! Bending it towing a donut I would question - ripping it out the transom is a possibility, but we donlt know how it's fixed in....... if the forward legs are anchored properly to the floor, it will probably survive.


OK, here's a halfway thought - At the mo, you have at least one bolt each side fixing the frame to the transom. You presumably have either an eyebolt & nut, or bolt & Eyenut. So, replace the non eye'd one so you have an eye each side (means you can still tow boats where the rope in the water isn't an issue) then fix the tow bridle to the inside eye, route it up over the transom & round the outside of the frame, & job done. Only possible problem I could see is the bridle fouling the engine casing.......
