Can be placed on both sides, or on one side. We have two different boxes so you can actually have the slant section pointed forward or backward on the port or the starboard! If you want more room to drive and to hunt in the rear of the boat, point the slant to the back of the boat. If you like the traditional look of the slant boxes facing forward, no problem.
Note, on boats 50″ and wider, if you are not 6′ tall, you may have an issue reaching the handle to drive the motor if your slant points to the rear of the boat. In those cases, point the slant to the front of the boat and you will have no problem.
