If you use the large ram mount it's pretty easy to remove the unit. All you have to do is loosen up the ball joint and then unscrew the connector mount on the back of the control head to remove the entire unit. Takes me about 1 minute if I have a screw driver handy. But I tighten up the screw that holds the wires onto the back of the control unit with a screw driver to ensure a tight fit.
I have heard of others not getting a good connection where the 12 V DC plug into the control head. Some times the pins don't make a good connection and you have to either bend pins to get a better connection or get a new power cord.
They also sell some locks that prevents people from loosening the screw on the RAM mount. And then you can buy other locking screws for connecting the control head to the metal bracket.
Still the main thing you have to worry about is some one stealing your SDHC card out of the control head when you are not looking. It's way to easy to open the SDHC compartment and to pop out a $200 SDHC chip and walk away with it while you are in the bathroom at the gas station on the way to a fishing trip.
So it would be best to just remove the control head off the boat and store it in a secure location until you are ready to launch the boat and fish.
You might want to get a pelican case to keep the control head in while it's off the boat. Those pelican cases are nice and very secure. Lots of photographers store cameras in them.
