Since we ware burgled on Rhodes a few years back I made a very low tech alarm system.
A 1,5 € piezo alarm witch is activated by touching a extreme fine fishing line that I rig around the cockpit. I mounted the thingy on a piece of ply, the small magnet connected to the fishing line.
Fishing line fed trough some stainless steel rings placed on the corners of the aft deck.
Anyone moving on the back half of the boat will touch the fishing line, the magnet is pulled away and the alarm sounds.
Thingy is in fact a window opening alarm.
Low tech, low price, functions excellent. Takes just a few seconds to rig the line.
Once returned to our anchored boat and the alarm was on. No burglary. Swimming thief must have panicked and left. Boarding ladder was pulled down.
Our buglers war two “kids” who came swimming, transported my laptop and the rest in a polystyrene fish crate. I may have seen the crate “floating” in the dirty harbour, had no idea my stuff was in and a rat was under it. We rowed back when they ware still on board. First thing my wife saw boarding our boat ware the wet prints of small bottoms on the wooden cockpit benches.
