Bear in mind that it's not just the motion sensor you have to worry about. The anti-tow stuff will be triggered if the alarm is on, but the vehicle moving. Not sure how your dog will react to that.
When travelling to Orkney on the ferry, I just sit in the cold with the dogs on my lap, but as I suffer badly from seasick, I'd be sitting outside anyway.

What anti-tow stuff? Darren

It does have tilt/nudge alarm doesn't it? I know my 2015's alarm goes off on a ferry if I don't lock with just the key.

No, I'm afraid not. Perimeter and volumetric only on the Defender. Darren

There is an inertia switch built into the central locking version of the AS10 unit, something I didn't know until this thread came up on the forum, see in particular Fifth Horseman's post about 9 down from the start.

Quote from TOPIX:

TOPIX wrote:
The anti-theft system module also incorporates an internal inertia switch. In the event of an impact of sufficient severity to trigger the inertia switch when the ignition switch is in position II, the anti-theft system module will unlock all doors and operate the hazard flashers. The anti-theft system module will remain in this mode of operation for 2 minutes. To de-activate the hazard flashers and restore the anti-theft system module to its normal mode of operation, the ignition switch should be turned to position 0 and back to position II after the 2 minute period has expired.

However it doesn't seem as though the inertia switch actually triggers the alarm, it just unlocks the doors and flashes the hazards, and so is unlikely to be setting the alarm off on a ferry. That, I would think, is more likely to be the perimetric or volumetric alarm being activated, perhaps by a loose connection (it would be interesting to read the AS10 data see what it thinks is the reason for the activation).

As far as i am aware inertia switch is only built in to AS10 2007 to 2011 as its not hard wired into engine loom
my 2006 with central locking version of the AS10 unit has no inertia switch and pos 2011 inertia switch are hard wired into engine loom again

Correct, the AS10 inertia switch is as far as I know only present on central locking vehicles which have a mechanical fuel pump and no electric pump, which is the 2.4 TDCi.

The TD5 and 2,2TDCi with electric pumps have to have an external inertia switch since the AS10 cannot turn off the fuel pump (which is I believe a legal and type approval requirement).

I don't know if those with an external inertia switch and central locking also have the handy "bump the vehicle to unlock it" theft feature, but I imagine that they do.

2012 Defender 110 Puma 2.2 XS CSW Orkney Grey

I think I may have made a little bit of a boob. I had the drivers lock removed as a minimal theft deterrent, but hadn't thought about locking on a ferry/when using a roof tent. Can I just manually lock via the rear door?

No, it's the drivers door actuator that switches the system on and off. Darren

I think you're referring to the crash sensing inertia switch, TD5 & 2.2TDCi have these as they have electric low pressure fuel pump, 2.4TDCi does not have said pump so also does not have the fuel cutoff inertia switch.
This is bolted to the top of the bulkhead behind the engine & wires into the engine management.

The 10AS has it's own internal inertia switch for releasing the locks in event of impact.
