XBee Box: DRY
Kill Switch: DRY
Winch: WET (1/2 cm water)
Electronics box: WET (1/4 cm water)
Batteries, linear actuators, motors: Completely SOAKED, filled with water
        -Battery still works
Water Cooling: WET (so water effectively flowed through)
Mast: broken
Skin: one hole from rubbing along the side of the rocks

Next Steps: 
-Replace motor (find more powerful robust motors)
-Redo water proofing (we should have ONE compartment / pelican case with a bilge pump rather than separate compartments for each item - but do we have         
        enough time? 10 days...) 
-Replace the mast
Linear Actuators: (unless we get new industrial ones)
    -replace the hall effect rotational sensor on the linear actuator (at least), but check what works
    -get better couplings for the motor shafts
-Get New kill switch
-patch the hole in the skin
-re-wind the winch line
-test the GPS
