Why the ship does not sinks?

    Why the ship does not sinks?
    A ship is loaded in such a way that even if a single coin is loaded on it more, the ship will sink. However, after it travels some distance in sea, a bird weighing 15 kg dies and falls on the ship but the ship does not sinks. Why?

    It's a riddle.

    I would assume that if the boat was that packed then rocking on waves would cause cargo to fall off?

    Well, since a single coin would sink the ship, I think we'll have to ignore rocking. But I think you're on the right track. After traveling some distance at sea, I suspect some things on the ship will be used up and make it lighter.

    My solution:
    It is a diesel ship and, after some distance, more than 15kg of fuel has been used up.

    That, or they used up more than 15 kgs of bullets shooting at the bird.

    The ship was loaded in a fresh water river then moved into the open saltwater sea.

    if the bird had been flying around in the hold, it would make no difference :smile:

    Ahah. I just figured it out. A clever riddle.

    The bird was not flying - which is what we've been assuming. The bird came aboard the ship in a cage.
    There is no such thing as a flying 15kg bird.
    It was a turkey, and it was killed for Thanksgiving.

    The crew all chundered 15kg worth of lunch over the side of the boat at the sight of the dead bird?

    Mute swan and some bustards fly at nearly 20 kg.

    There was a mute swan found in Poland that weighted 23 kg, although there are no reports about it flying.

    Perhaps the coin and all of the load was placed on the port side so that the ship was listing severely to port, but the bird fell on the starboard side.

    There's a more obvious suspect for the bird, this being at sea:
