I had a stealth 12th for a while great harbor yak I put a Scotty rod hold in front of the cup holder and one on the bait tank hatch...
or you could make something like this for behind the seat
Also if you take it offshore/inshore you might want to put a bilge pump in as the side hatches leak I had one in mine and it saved me a few times... Especially if you're planning on doing surf launches
