A civilization flourishes based on its trade and commerce, and Mesopotamia was no exception. They wanted to set up trade relationships with nearby cities and countries. Since transportation of goods by land routes was hectic and difficult during those days before the concept of road routes weren't even conceived, they had to figure out an alternative mode of transportation to transport goods and people. This came in the form of water transportation, and thus the first boats were invented.
They were simple wooden boats that would carry people and goods downstream and then back upstream. But boats need people to navigate and guide them across rough waters, so the solution of having a vessel carry their goods and people had to be refined. Thus the sailboats were invented. They were primitive in design, but the sailboats helped the Mesopotamians in trade and commerce.
They helped in irrigation and fishing too. Mesopotamians had mastered the art of fishing. They would go downstream using sailboats, cast their nets, stay, wait and return with the catch. Thus the sailboats of Mesopotamia helped the Mesopotamians establish trade relationships with other cities and countries, making them one of most famous civilizations to flourish and change the course of history with their inventions.
