How do you guys monitor trim and list?

Best regards,
Jens Laland

** On my boat I monitor:
** CO2 ppm
** O2 mole percent
** Water pressure (sensor and manual)
** Cabin pressue
** Water temperature
** Cabin temperature
** Cabin relative humidity
** Main battery voltage
** Aux battery voltage
** Main battery current
** Aux battery current
** High pressure air
** Regulated air pressure
** O2 pressure
** Speed via DP sensor and pitot tube
** Hatch closed sensor
**
** All sensors tied into PLC and displayed on a Touch Screen display.
** PLC has an alarms database that triggers an audible and visual alarm
** when any of these measurements goes outside of acceptable limits.
**
** An interlock systems prevents diving the boat if hatch is open or
** insufficient air pressue is availale to blow the ballast tanks.
