Move these items about before securing them so your outfit will perform to its best capabilities. Also where possible you should try and include pedestal seats as they make time on the water much more relaxed and comfortable than it would otherwise be sitting on a hard seat. On the blue water scene, options again vary. From extra rod holders to a GPS, there is so much you can add to your chosen rig. A SportsPilot is another great idea for sport and game anglers who travel long distances and do many hours of trolling.
Outriggers are another item often overlooked on small boats.
Usually seen on bigger game boats, outriggers have many options, like spreading lines well apart over a reef, drifting with live baits and general trolling. Bilge pumps are again essential on blue water boats. The size of the pump is also important. Small slow pumps are relatively useless if you take an a large amount of water crossing a bar. I prefer to have the outlet of my bilge pump through the drivers aft side of the boat.
