My lock safety alarm ???

On a more serious note, I can see some hire companies being interested

200 quid???!!

I bet the alarm bells are set to ring anywhere North of Middlewich....

An old Cobra car pendulum burglar alarm would do the same thing.  Or a soup ladle hanging on a bulkhead hook with contacts on either side wired to an electric bell.

   To cope with every angle under the sun suspend the soup ladle from a hook on the ceiling above a table. Encircle the spoon end with a steel wall. ''Meccano is ideal for this'' pretty close to the ladle, and any slight difference in angle in any direction the ladle will strke the Meccano wall making an electrical connection and set off a warning hooter.

But how do you compensate for the convex side of the ladle. That has to trigger earlier that the concave side so you end up with disparate responses......... just saying

Exactly the same difference between the filling and emptying times of top and bottom gates on the Atherstone flight.

Ok, dangle a sash window sausage weight.

In actual fact a large brass bell sitting upside down upon the table with its clapper removed and dangled from the ceiling instead into the bells mouth. The bell ringing should be loud enough to raise the alarm without an electrical hooter.

  No, better electrfy it to give a continuous hoot as the clapper hits the bell as just one dong on the bell might not be heard.

A completel portable one could be made out of Meccano, a cage like construction with the weight dangling inside a metal dish with its own battery and electrical warning hooter. The cage cam be provided with a nice comfy handle to carry the cage about like you would a Canary.  Ideal if visiting different boats and to alleviate worry in a rough sea if you go on a cruise ship, the other passengers will be impressed.

LockAngel’s electronic sensors constantly monitor the angle at which the boat is lying in the water. Any change is analysed, and if LockAngel senses trouble, it sets off an alarm.  The alarm works like a car’s reversing sensor. At first, LockAngel bleeps slowly to alert you to the fact that something may be wrong. It’s an Early Warning, so that you can check that everything’s OK.  LockAngel call it a high tech spirit level

I would say after a very short time most people will switch off due to false alarms.

Slight flaw in this. 

 

Surely if you are within earshot of ze hooter you would be aware of the burglarist anyway.

Does it still work with the new fangled plastic Meccano?

I believe a simpler solution would be to have a recorded voice loop saying "Oi! Pay attention - you're in a lock!". The more widely employed form of this reminder device, which covers many more siruations but appears to have no off switch, is to go boating with a wife.

Or even a mercury "tilt" switch or two (for port & starboard and fore & aft tilts) from an old juke box ?

[Tony Brooks]

How about re-purposing an old smart phone. I think they have poition sensors.

[matty40s]

Pinball machine tilt mechanism, electric shocks along the metalwork to make sure you dont ignore it.
