English: A ship-rigged cat-bark is shown on the right, with her anchors raised and making sail in very calm conditions. She is a Danish trading vessel flying their flag from the stern. Such ships were immensely strong and used to carry large tonnages such as wood. She is distinguishable by the lack of a figurehead at a time when even humble craft carried some form of decoration on the bow. The men on the deck appear very small in scale to emphasise the dimensions of the ship. The crew of the small boat are either hauling up the bark's anchor with the aid of a davit in the stern, or possibly shifting it in order to kedge her forward given the lack of wind. The deck of the bark is crowded with men heaving on halyards and making ropes fast, while high above them half a dozen sailors are perched on the yards loosening the sails. Piles of timber unloaded from the bark are shown on a barge to the left with its identifying number '472' clearly visible. Such details assert the concern of the painting to demonstrate the importance of trade and this is underscored by the inclusion of the other shipping, such as the craft on the right, which is flying the Dutch flag. The action takes place near the mouth of a river and is probably set in the Thames near Gravesend.
