Over all this will make a nice addition to Wikipedia as either a stand alone article or an expansion to an existing article about tramp shipping/ trade. The citations in your work are all correct but I am not sure if the ISBN numbers are needed as part of the references. All of the coding with in the article is done correctly and free of problems as well as proper usage of inline citations with a reference list.
The work is written in a very neutral point of view with an intent of only informing the reader about tramp ships and how they operate with the different types of contracts that can be made between owner and charterer. Also the sources you used meet Wikipedia's criteria for reliable sources and they are used properly to support the information given in the article.
