That's a good idea... I trolled around on office depot's website and they have some stuff that is close.

The size isn't quite right unfortunately, and the price is more than Basscat wants.

I'm leaning toward those Basscat boxes, just wondering how they mount in to the boat. Like if they are loose or if you screw them them in. I'll find out and post when I do.
