PROBLEM TO BE SOLVED: To exploit a boat for the labor-saving and automatic laying of a marine algae-plantation net for producing marine algae in large scale at a low cost in the sea to use the algae for energy source, industrial material, etc., and improve the global atmospheric environment. SOLUTION: The objective boat 10 for laying a marine algae-plantation net is provided with a marine algae-plantation net, a rope, an anchor 5, a buoy 8, etc., and further furnished with a spore-attaching tank for marine algae plantation, a connection mechanism for cultivation net, a large-scale crane, etc. The plantation net is flowed on a gentle sea current from the downstream toward the upstream of the current and finally an anchor and attaching main rope 4, buoy, etc. are thrown into the sea with the crane 9 to complete the laying of the marine algae cultivation net. Since the main rope 4 is designed to have a length sufficiently longer than the depth of the sea, it does not exert bad influence on the other equipment.
