The links to the folding platforms are in post number 14 in this thread , which you should be able to see here
But here's a picture of what I meant:
I like your idea of passing the stuff down to your dive buddy. Getting out, when you're tired, could be more exciting. And I like the Pearson's rail and ladder; that's much better than the C25's. I'm 99% sure the 25's rail actually leaned out, which made climbing over it very awkward. The cleat location made it really hard for my kids to climb under it, too. So, we're looking forward to a new solution!
Thanks for the pointer to Catalina Direct for the ladder "steps".
