To provide a vessel including a hard sail capable of smooth elevation work in a short amount of time without higher cost, deterioration in propulsion force, or increase in weight.SOLUTION: An angle increase suppression mechanism 37 includes: a movable frame 39 including vertical frames 45A, 45B of size L2 in a vertical direction VD greater than size L1 in the vertical direction VD of a device body 35 supporting a hard sail 27 and elevating in a hanger 29, and provided to be capable of sliding in the vertical direction VD against the device body 35 with the pair of vertical frames 45A, 45B in a state of having one portion superposed with the device body 35 in a through-view from a direction of travel FD; and a contact unit 41 attached to the movable frame 39 and composed of a plurality of rolling motion rollers 43 moving in contact on a side surface of the device body 35 in the direction of travel FD and at the same time facing the internal wall surfaces of a pair of partition wall plates 31A, 31B, in which increase in angle is suppressed between a virtual center line C extending in the vertical direction VD of the device body 35 when the device body 35 is elevated and a vertical line V.SELECTED DRAWING: Figure 6

    【課題】コスト高や推進力の低下や重量の増加を伴うことなくスムーズで短時間の昇降作業が可能な硬帆を備えた船舶を提供する。【解決手段】角度増大抑制機構37は、硬帆27を支持し格納庫29内を昇降する装置本体35の上下方向VDのサイズL1よりも大きい上下方向VDのサイズL2を有する縦フレーム45A、45Bを備え、進行方向FDから透視して一対の縦フレーム45A、45Bが装置本体35と一部が重なる状態で装置本体35に対して上下方向VDにスライド可能に設けられた可動フレーム39と、可動フレーム39に装着され、装置本体35の進行方向FDの側面上を接触移動し且つ一対の隔壁板31A、31Bの内壁面と接触可能に対向する複数の転動ローラ43よりなる接触部41を備えて、装置本体35が昇降しているときの装置本体35の上下方向VDに延びる仮想中心線Cと鉛直線Vとの間の角度の増大を抑制する。【選択図】図6
