DIDSON Mounted on a Kayak

A kayak is a great way to inspect a dense relict pile field. On the topside, a tote between the paddler's knees shields the laptop from
spray and sunshine; the lid and back are partially cutaway to access the keyboard. The ethernet cable runs from it back to the little
clear tote in a well behind the paddler where the power supply box is. The DIDSON cable enters that through a hole also, and so do the
+/- leads to two small sealed absorbable-glass-mat (AGM) 12 V batteries in series, that sit in the well right behind the backrest. The
kayak is a sit-on-top style Cobra 'Fish-n-Dive'. It is very stable and no modifications (drilling, cutting, or gluing) were required. It has 8
drain holes that go through the hull, so those were used to run the mounting bracket bolts and the cable. The well in the back is meant
for holding scuba tanks and such, so the excess cable is coiled in it with the tote set on top. There are little clips on the hull to strap everything down with bungie cords.
