What no-one has mentioned is that apart from volt drop, the length of cable and resistance, may cause the safety device (RCD), at the shore connection, to become inopererative...
According to VicS "The resistance of 1.5mm² is 11.2 ohms /1000m or 1.12 ohms /100m". The 2.5mm² cable will be less. An RCD needs 30mA to trip (or about 7k ohms), I don't think an ohm or two will make much difference.
