The effectiveness of a adhesive metal sheet on prevention from adhering the life of a marine, which consists of cuprum nickel alloy and strong adhesive cement, was confirmed by test plates submerged in sea during four months. In order to examine the resistance increase by roughness of barnacle, shell and overlap of adhesive metal sheet, the resistance tests of flat plates with replica of barnacle, shell and with overlapped sheets in some ways were carried out. Roughness function for each rough surface was obtained from the test results. Finally, the resistance increases of two kinds of crafts, fishing boat (Δ=10t) and yacht (5.5 metre), are estimated from the present experiments. The increment of resistance by overlapping the adhesive metal sheets can be hardly found. The resistance increase of fishing boat due to barnacle, shell is about 7% and that of yacht is about 30%.
