I got the panel from FleaBay. I am not sure what a "marinized" panel would look like, they are all designed to be mounted outside. I have no permanent mount for it, it is on the end of a 40 foot cord and I move it around different places to catch the sun.
K_I_S- Is your panel "marinized" or are you just using a residential house panel? What kind is it?
I'll assume that you're hanging it off the aft pulpit? Did you fab the brackertry?
