 note = {In March of 1991, Training Ship Keiten Maru changed the paint of ship bottom to the new self-polishing anti-fouling paint. This paint, not contained the organic tin (Tri-phenol tin) caused the environment destruction, was developed for the next period. In this paper, analyzed the cruise data of scientific surveys from 1989 to 1991 in the deck log-book and engine log-book, and study the effectiveness of this paint as compared with the old one in the open sea in regard to propulsive efficiency. The results are as follows: 1) According to fuel consumption coefficient, a new bottom paint has prove superior to the old one. 2) According to slip ratio, a new bottom paint has prove inferior to the old one. 3) The relation between effective horsepower and sea speed, a new bottom paint is constant as compared with the old one, and has the superior propulsive efficiency. But these make no appreciable difference to numerical values. As a result, a new bottom paint is as effective as the old one with regard to prevention of bottom fouling, and has the superior operating efficiency., 1991年3月敬天丸は新規研摩性船底防汚塗料に塗り換えを行った。この船底塗料は環境汚染の原因となる有機錫を含まず,従来型と同じ防汚効果を発揮するように開発された。有機錫を含まない新規の塗料として登場した船底塗料の効果を従来型と比較して,推進性能の面から検討するため,塗り換え前後3年分の特定研究航海から,その資料を航海日誌,機関日誌より抽出し,解析を試みた。その結果,次のことがわかった。1) 燃料消費係数を比較すると新規研摩性船底塗料が優れていた。2) スリップ比を比較すると旧型の方が優れていた。3) 馬力と対水速力の関係をみると,新規型がバラツキは小さく安定した推進性能を発揮していた。しかし,これらの値には大きな差異はなく,新規研摩性船底塗料は従来型に比べて劣らない防汚効果が発揮され十分な推進性能を維持していることがわかった。},
