An overboarding and/or retrieval device 110 for controlling a curvature when overboarding or retrieving a flexible elongate element 112, such as a subsea pipe or cable from or onto a vessel 116 whilst accommodating an accessory 114. The device comprises movable support element 120, defining an endless guide path 122 and having at least one accessory-receiving opening 124 thereon. The endless guide path has a first path portion 142 defining a first curvature, and a second path portion 144 defining a second curvature which is different from the first, the second path portion being interposed between the accessory-receiving opening and the first path portion. Also disclosed is an overboarding or retrieval device, wherein a moveable support element 120 is moveable by a drive transmission element (656 figure 13) and defines an endless guide path defining a circulation path (630, figure 13), where a convergent path portion (650, figure 13) converges with the circulation path, and a divergent path portion (644, figure 14) diverges from the circulation path.
