No not really,
If I recall I used a single sheet of 3/4 (maybe 5/8 it's been a while) marine plywood and cut it to fit into (over) the present small one. Since it was supported by such it only need a few short 2x4 legs to support the other open end. Worked nice and even added some extra space to pitch stuff under. Since it was not mounted per say, you could still lift it up to get into the small forward storage compartment or just take it out if you like.

Once installed, I rarely took it out since it added so much to the boat and if I did, it was to take the boat to the shop or if it was going to be setting for a while (before I had the cover) to keep from getting all wet from the rain. I have a sick little girl home with me today (man is it quiet here) and I will see if I can find those pictures and post them for you
