When I bought my boat an extra4 drawer tackle box (front has a door with 4 slide in trays) came with the boat. I was going to add abox under the leaning post. I was wanting to know if anyone hassomething like this is it built out of 1/2 inch or 3/4 inch starboard. I figured I would use aluminumand rivets to join thestarboard.And just bolt it to the leaning post and maybe some rivets tothe seat. Any suggestions appreciated.
