Abstract

Experiments were carried out to measure the variation of the compass error on ship's head up bearing by magnetic compass and electromagnetic compass on berthing at the pier in order to obtain a basic information on the utilization of autopilot system using electromagnetic compass in fishing boat. The wooden fishing boat, turned on attracting fish lamps of power consumption 85kW, steering magnetic compass and electromagnetic compass indicated westerly compass error with 7$^{\circ}$ and 13 $^{\circ}$~16$^{\circ}$ respectively. The FRP fishing boat, turned on attracting fish lamps of power consumption 130kW, electromagnetic compass indicated easterly compass error 19$^{\circ}$~23$^{\circ}$. The steel fishing boat, turned on ship's navigation equipments of power consumption 225kW, steering magnetic compass indicated westerly compass error with 16$^{\circ}$. While the difference of compass error using electromagnetic compass indicated westerly compass error with 68$^{\circ}$ on the upper deck when the navigation and fishing equipment turn on compare to turn off the equipment, it had easterly compass error with 16$^{\circ}$, 32$^{\circ}$, 20$^{\circ}$ on the forecastle deck, wheel house and compass deck respectively.
