An old milk crate is just the right size to hold ten utility boxes, 3600 sized.  You can add a strap or bungee to hold them in place but it really isn't necessary.  Acquistion costs are minimal.  I added a 1/4" plywood shelf in the middle to seperate it into 2 compartments since this pic was taken.   Does this qualify me for "Thrifty Bass Fisherman of the year?  

Acquistion costs are minimal.

lol!

Looks like a thrifty idea alright.  Where do you put it in the boat?

Fortunately on Tritons the front storage is made for 3700's and so are the two rear storage compartments.  

That is one great idea though!  I could have used it before I owned a boat.

I stand it up in front of the steering console, on the casting deck.
