PURPOSE:To prevent a laid net from hooking a fishing boat, by providing a telescopic supporting member, overhung to the front in the upper part of a bow, an extendably providing plural net-interrupting ropes between this telescopic supporting member and a spherical protrusive part, in case of the finishing boat equipped with the spherical protrusive part in the point end bottom part of a ship body. CONSTITUTION:A point end spherical protrusive part 2 is provided in the bottom part of a bow, and a fishing boat 1 of lightship or fish searcher boat provides in the bow upper part a telescopic supporting member 3. This telescopic supporting member 3 is constituted of a rear part fixed member 4 formed by an angular pipe fixed to a deck extending in the longitudinal direction and a front part movable member 5 inserted being slidably fitted to this rear part fixed member 4. The fishing boat 1, hanging down a supporting rope 16 through a pulley 14 from the point end part of this front part movable member 5 and connecting plural net-interrupting ropes 6 to the bottom end part of this supporting rope 16 through a connecting ring 17, connects bottom end parts of these ropes to brackets 18 in the point end of the spherical protrusive part 2. In this way, the fishing boat 1, when it sails, prevents a laid net 9 from riding on the spherical protrusive part 2.
