Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fin device and a craft, which can achieve energy saving of the craft by improving propulsion efficiency of a slow-speed zone except a bilge vortex.SOLUTION: A fin device 2, which is arranged in a hull provided with a planar side flat 11 formed in a craft length direction on a craft side, is provided. The side flat 11 has an inclined part 11a that constitutes an outer edge ascending to a deck side from the side of a bottom 13 toward a stern part 12. The fin device 2 has a fin 21 that protrudes from the hull within a range below the inclined part 11a and above a bilge height. 【課題】ビルジ渦以外の遅速帯における推進効率を改善することにより、船舶の省エネルギー化を図ることができる、フィン装置及び船舶を提供する。【解決手段】船側の船長方向に形成された平面状のサイドフラット１１を備えた船体に配置されるフィン装置２を有し、サイドフラット１１は、船尾部１２に向かって船底１３側から甲板側に上昇する外縁を構成する傾斜部１１ａを有し、フィン装置２は、傾斜部１１ａよりも下方かつビルジ高さよりも上方の範囲内に船体から突出したフィン２１を有している。【選択図】図１
