PROBLEM TO BE SOLVED: To provide a fishing boat, using NGH for fuel, in which water obtained by decomposition of NGH can be effectively utilized. SOLUTION: The fishing boat 10 is provided with an NGH tank 11, an NGH decomposing device 12 to decompose NGH fed from the NGH tank 11 into fuel gas and water, a gas engine 14 as a main engine driven by fuel gas generated by the NGH decomposing device 12, a refrigerator tank 18 using NGH decomposition water generated by the NGH decomposing device 12, and a water storage tank 22 to store NGH decomposition water passing the refrigerator tank 18 for life water in the boat. NGH decomposition water secondarily generated by the NGH decomposition device 12 is fed through a buffer tank 17 to the tank 18 to be used for cooling water for cooling the inside of the refrigerator tank 18. Since the NGH decomposition water is sufficiently cold, temperature in the refrigerator tank 18 can be kept low, thereby freshness of fish stored in the refrigerator tank 18 can be maintained.
