I built it myself. I've added a couple of pix to the library, that show a hatch I added at the bow, some storage trays in the gas/battery compartment, and my handy/dandy retractable GPS unit. It's on tracks that let it slide under the rear half of the deck extension when we're fishing or pulls out for easy viewing and access while underway. The forward half of the extension holds 12 3700 boxes.
Hah! You'd be surprised Tox...the new ones has foam in ALL the extra areas. I was surprised myself...I checked and Tracker is way over the minimum foam for that size boat. It actually has more than the Express models. Last year on Lake Erie two guys in an Express was swamped..they got rid of everything heavy and it stayed on top and was eventually rescued by a freighter.
The new ones are not unsinkable but, I feel safe enough to stay with my rig when in open water if that ever happens.
