If it's fine on shore power but won't stay cool on ship's power, the DC side isn't getting enough voltage. The low-voltage protection is shutting the compressor off. Check the voltage right at the fridge while the compressor runs. If it drops much below 12V, look at the battery, connections and wire size. Undersized or long wire runs are a common cause on boats.
