The dry cargo market is the one which experiences higher interest since the type of vessels are much more. Since we have seen such a big variety of vessels in the OpenSea marketplace and since the vessel designs change rapidly from time to time, we decided to present a brief updated guide of the several types and sizes we may see around the world marketplace.
