That is a cool mod Frank.

How much chain do you plan to carry? how much higher would you estimate that shelf would make the chain?

I like the mod, and would think it would be a good way to 'segregate' the chain locker. I plan to carry more chain then I really want to use on a regular basis. Maybe the regular rode (mine is 150') with 30' or so could ride on the shelf while the remainder is laying at the ready below, with the spare anchor and other stuff that could get stand to get wet every once and a while.
