We make square and rectangular tanks for one simple reason. Where they will fit on a boat? Some boats are limited in deck space or the owner may not want a tank in the center of their cockpit or on their swim step or the cockpit may be a little tight.

Rectangular tanks are deeper but narrower than our ovals,
so in some cases this gains fishing or walk around room in the cockpit. Squares and rectangles fit up against bulkheads, in corners, or beside existing cabinets very well and they look like they belong there. Contrary to popular belief these tanks hold bait very well. Proper flow through the tank provides the bait with what they need, not shape. Square and rectangular shapes also allow us to build tackle centers and cabinets or, in the case of divided tanks, we can make bait tank/tackle center combinations.
