"Is the very most front piece screwed down to the wood frame below"::
Nope it just lays on top of the rib coming up from the bow. I never used it as a casting deck, just a place to hide my anchor and life jackets.
"do the hinges open both the very front section (so you can get to your anchor) and the next split section" ::
Just the two doors open up. I had enough room to store my anchor and line, life jackets, and a few other accessories.
"I'd like to have my deck just like yours but have both section open, my only difficulty is keeping it closed while in transport" ::
My doors fit together tight enough that I never had to worry about them flopping open.
I was sad to see my boat go. I did a lot of work, but I was able to upgrade to a nice Crestliner this summer with a 25hp on the back. Next year I will get a newer motor and put a steering counsel and re-carpet and seal the floor. When I did my old sylvan I sealed all the wood with water seal and then carped over it. I should have used glue along with staples because i did have some ripples the following year in the carpeting.
hope this helps,
