I have a 15 foot Smokercraft Alaskan, and space is really tight. There are a couple things I do that make life pretty convenient, however, particularly with the downriggers. I mount them pointing up at about a 45 degree angle. This eliminates having to hang over the side to retreive your booger ball or reach your release - really nice on a rough day! Also, I mount a plastic booger ball holder, the square kind you get at Sportco, right under the reel, so when I retrieve my ball I just set the cable in the spool and slack the line, falls right into place. The upward angle does put them a couple feet closer together, but unless I turn 90 degrees, like I do occasionally to miss the Bayliner that can't see me, things don't seem to tangle too badly. And actually I can turn it 90 degrees to the right and get away with it, just not to the left, as then the lines cross.

I troll with either the motor (I only have one, 4 stroke) or the oars, especially use the oars when I'm drift mooching or fishing kokes, sockeye, lakers, etc. So I mount my fish finder on the seat next to me on teh left side, right about in line with the tip of my rod when trolling with the motor. When I'm on the oars I turn it to face forward so I can see it easily.

For a tackle box I like a big trunk style, and I stick it behind the motor seat next to the gas tank most of the time to get it out of the way. Also throw the knife and cutting board back there - I wholeheartedly agree that you want absolutely nothing on the floor that you can step on when fighting a fish!

My oars get strapped to the gunnels with a bungee cord on one side, and my rods get slipped into the bungee and rest on the oars - really protects them well as you can't break them unless you break the oars too! The fish box usually gets strapped down in tbe bow, and the bag of the net sits over the fish box with the handle pointing back at me if I'm alone. I have 3 swivel seats in this little boat and can fish 3 people just fine if the weather behaves - not a lot of room to run around but enough to streatch out. I may have the littlest boat in the fleet but I can also fish an 8 hour day on 3 gallons of gas
