OK, got that thumbnail thingie handled. It's too easy, that was the problem.
This is looking straight down into the bow tank through the new port (or more precisely, through the hole the new port will be installed in). That blob looks like it was probably dripped onto the styrofoam during the original installation (can't think how else it would have gotten there). This leads me to believe that the styrofoam is the original stuff.
It hasn't fallen down into the bilge, I think because at the bottom of the tank there are a couple of horizontal pieces forming a plug.
And here are the stemhead and bow cleats, looking pretty secure (without knowing what's behind the goop, or how well it will hold).
And here is the bow hook. Looks good except for the corroded nuts.
