on the 16' raft, I use a 4 bay frame. My towers are towards the back of the second bay, from the stern. I sit on a large cooler, the second bay, (from the stern) is the captains bay (arrrgg), and then a drybox, and then 5 ammo cans.
the 12' cat is set up with towers about 6" forward of center, on a three bay frame, it has two seats, and with a passanger, I slide up a bit, but not much.
