The invention relates to the technical field of ships, aims at solving the problems that in the prior art, an anchor abandoning device is long in anchor abandoning operation time, the time effect of anchor abandoning is affected, the structure is complex and water leakage is likely to occur, and provides an anchor abandoning device, anchoring equipment and a ship. A base of the anchor abandoning device is arranged at the position, close to an anchor gear, of a forecastle deck; a plug-pin detachably penetrates through a first open slot and a second open slot of the base; the base is close to the anchor gear, the installation position of the anchor abandoning device is close to anchor gear operation personnel, and the emergency anchor abandoning reaction speed is high; meanwhile, the anchor abandoning device is arranged on the forecastle deck, water sealing treatment is not needed, and the structure is simple. The anchoring equipment comprises the anchor abandoning device, and also has the advantages that the emergency anchor abandoning response time is short, water sealing treatment is not needed, the structure is simple, operation is easy and the quick anchor abandoning can be achieved. The ship comprises the anchoring equipment, so that the ship also has the advantages.
