To provide a water surface floating article recovery ship capable of efficiently recovering a water surface floating article in a hull by controlling a water flow generated inside/outside the hull through driving of an outboard engine attached to a hull rear part, and an outboard engine duct.SOLUTION: A water surface floating article recovery ship 1 comprises: a hull body 2 in which a recovery chamber 21 for storing a water surface floating article F recovered inside is formed; buoyancy bodies 3 installed in both sides of the hull body 2; and an outboard engine 4 that is a driving source installed in a stern to drive a propeller 45. An outboard engine duct 5 roughly cylindrical and including the propeller 45 is installed below the outboard engine 4. A water flow discharged from the hull body 2 passes through the outboard engine duct 5 to become a jet. Thus, a water level difference in the recovery chamber 21 can be maintained constant.SELECTED DRAWING: Figure 1

    【課題】船体後部に取り付けられた船外機の駆動により生じる船体内外の水流を制御することにより、水面の浮遊物を効率的に船体内に回収することができる水面浮遊物回収船、及び船外機用ダクトを提供することを目的とする。【解決手段】水面浮遊物回収船1は、内部に回収した水面浮遊物Fを貯留するための回収室21が形成された船体本体部2と、船体本体部2の両舷に設置された浮力体3と、船尾に設置されプロペラ45を駆動するための駆動源である船外機4を備える。船外機4の下方には、略円筒状であり、プロペラ45を内装する船外機用船外機用ダクト5が設置されている。船体本体部2から排出され水流は、船外機用ダクト5を通過することで噴流となり、回収室21内の水位差を一定に保つことができる。【選択図】図1
