If I'm not mistaken most are around 34" apart. I no longer have it but this is how my Bass Tracker was set up. Just before I sold it I did away with the double seat base. I added 2 individual mounting plates to the deck it self. I mounted them back from the bow a few inches behind the center seat post. This seemed to work better for me. Fairly easy to do as the front deck unscrews easily. Good luck hope this helps.
