1. A fuel remaining amount measuring apparatus for a boat, the fuel remaining amount measuring apparatus comprising:
a fuel tank containing fuel;
a load sensor to measure a weight of the fuel tank; and
a corrector to receive a measured value T1 of the weight of the fuel tank detected by the load sensor, and to correct an error due to at least one of a movement or a tilt of the boat; wherein
the corrector includes:
an acceleration sensor to detect an acceleration of the boat;
a calculator to correct the error based on a value g of the acceleration detected by the acceleration sensor; and
a storage to store a value g0 output from the acceleration sensor in a reference state where a speed and a tilt of the boat are both zero; and
the calculator corrects the error by multiplying the measured value T1 of the weight of the fuel tank detected by the load sensor by a value g0/g.
