As I've done in all my other boats, I put 2 baskets on the table. These are secure by non-skid mats. They haven't moved an inch since I placed them, and I've had this boat in some fairly rough seas! The one basket is for fresh produce, which really does better in a well ventilated area than in the refrigerator, and the other basket is a catch-all for miscellaneous gear; such as guides, cameras, sunglasses, etc. This system has always worked very well for me in the past and it is doing so now.
The window shades were ordinary vinyl pleated shades, from Lowes, that I took apart and sized accordingly. These work even better than I expected.
The cable that you see coming out of the air conditioning vent connects the WIFI amplifier to the computer and can be conveniently stored inside the vent.
