Many believe the best shape for a bait tank is completely round. The debate over this will probably go on forever. However, there are a couple of problems with this. The biggest in is room. Cockpits in a boat are square or rectangular. Place a large circle in the middle of a square or a rectangle and you will find it will eat up all of your fishing room in a hurry. Add a few deck hatches, chairs, or an engine box and all of sudden the size of the circle that will fit gets pretty small. Pinch that circle into an oval and you have a shape that maximizes capacity, fits between hatches, and leaves you room to fish.

Divided tanks are a great way to separate baits or reduce the water weight you are carrying as you use your bait. However a single tank will always hold more bait than a divided tank of the same size. The reason is swimming room. Even though the tanks hold the same amount of water and are the same size on the outside you loose internal area to the divider and a second set of baffles. Thus, a single tank of the same size will have roughly 25% more room for bait. This is why the first size of divided tank we offer is the OS-65-OD. We feel the divided chambers in tanks smaller than the 65 gallon model are just too small and you loose too much capacity.
