PURPOSE: To ensure travelling on a narrow waterway and wide space for loading laver by widening a plane shape of a bow deck section of the laver fishing boat which arranges an engine chamber and a bridge to the rear and the low deck to the front and forms a bow section in a V-shaped form and a stern section in a flat- bottomed boat form.

CONSTITUTION: In the laver fishing boat which installes the engine chamber and the bridge 2 to a section more back than the center of the hull and mounts the bow deck 3 to a section more front than the chamber and the bridge while forming the ship shape in a V-shaped form in the bow section and in a flat-bottomed shape in the stern section, the plane shape of the bow deck section 3 of the bow section is formed in width wider than conventional boats 31 so that the width 30 of the hull on the ordinate No.8 is made 90% or more of the maximum width (No.5) of the whole boat. Accordingly, the bow deck section 3 as the laver loading space can widely be ensured though the boat has a shape convenient for pushing throuth the narrow waterway.
