i think im going to have to try this mod!
it looks like you didnt have to undo the fabric all the way. just about 10" or so. right?
is the hump in the plastic or in the padding?
is it a lot easier to back-mount like this?
Yeah, I undid the staples about 10"s. I only cut the seat fabric to the necessary length then restapled it. Use stainless or rust resistant staples though. Mine are rusting out.
The hump is the rolled up padding. I just cut it to the lenght I wanted, then rolled the flap over. I works great.
Back mounting this mama jamma is better than ever. You never get your vest caught on the lip, you can keep you center of gravity lower in the rough surf, and you can actually utilize the back deck of the ski. If you have the time, try it out.
I'll be making a custom seat cover for this pretty soon, so I'll keep you guys updated.
