Aluminum questions, for pontoon tow bar

[calvinator]

Hi all -

I'm putting a ski tow bar on my pontoon. It is pretty much a custom build b/c my pontoon is from 1989.

I've spent 3-4 months researching and I think the best solution for me is to attach 5' of aluminum flat bar to the cross members of my pontoon. This flat bar will extend 6" off the transom of my pontoon and this is where I will bolt on the tow bar legs.

Here is an example:


Here is my exact tow bar:


The larger bar will be bolted to these new support legs. The smaller support bars will be bolted to my transom pod (which is all aluminum , gusseted, strong..).

So my question is about aluminum support legs. I could do a bunch of research on the net, but I figure I'd ask here first for faster answers:joyous:

My first guesstimate was to use 1" x 4" x 60" aluminum flat bar 6061 for these support legs. Strong enough ? Am I even close ? Overkill ?

THANKS
