| The electronics, water intrusion alarms: |
The hull is divided into three separate compartments, the aft most one holding rudder shaft, propeller shaft and main engine.
The middle- and bow compartment holds everything else. You should therefore build three of the systems shown below.
Should the weak points (rudder and prop shafts) or hull in general leak, then the pump should ensure that the compartment
should not flood. The bow thrusters in the foremost compartment is almost certain not to leak, but again there's a pump to
handle the event.
This system works automatically. The top sensor pins are located 3/4" (2cm) above the bottom, while the bottom sensor is
located as low as possible, but just a tiny bit above the intake hose for the pump. When the water reaches the bottom
sensor, it primes the pump. When water reaches the top sensor, the pump starts, and keeps on running until both sensors
are dry.
The exit hose ports from the pumps must be placed well above the waterline, so that no water can run backwards in
the systems, thus flooding the compartments. The test-button and LED's should be placed on the control panel for periodic
test and indication.
System schematics:
Please see "Components Pin-out’s" for details on the digital circuits.
It is vital that the pins are made of stainless steel, as they need to be operational at all times to ensure safety of the ship.
Test them once in a while by spraying water on them while your ship is in it’s stand, and keep them clean.
Also ensure that no water can penetrate through to the cobber in the wires, as this would corrode and destroy the very
important electrical contact without any visible warning.
