Internet technologies are an essential aid in the use of services in everyday life, and thus facilitate private and business life. Such types of technologies in transport are especially emphasized, but for the purpose of work, it is based on those that are of great help in maritime affairs. Without these types of technologies, it is unthinkable today to conduct any kind of maritime business, and it is extremely important to put emphasis on safety, which is the key to maritime affairs. Internet technologies are tools used by all employees in the maritime spectrum, and help guide the vessel through the AIS (Automatic Identification System), but also communication with the coast and associated segments of coastal guidance, until the embarkation of seafarers, or all those involved in maritime business in which a large role is played by the segment of human resources, and in this case of maritime agents. Namely, communication is of primary importance, and communication with the whole world is necessary for the business to run smoothly, with an emphasis on great ease of work and speed of its execution. Rapid communication between employees in the maritime business includes processes that include the ones that take place between maritime agents, agents and seafarers, and agents and companies to which the seafarer is scheduled to board, but also to resolve technical difficulties and provide berths, vertical or horizontal, i.e. stern-to or alongside, checking the availability of berths, accompanying paperwork with vessel data where uninterrupted and daily communication with customs must be ensured. Keeping records of seafarers, and those who are just starting to do so, is important insofar as it provides the person conducting the embarkation with full documentation, whether it is the relevant medical paperwork or the certificates that the seafarer must have in order to meet the requirements for boarding, which we also call brevets. Such certificates are entered in the maritime book, which is issued by the Port Authority within the Republic of Croatia, where the examinations of the aforementioned are also taken. Various private maritime staffing agencies offer courses to take the necessary certificates, in order to better prepare the seafarer to take it, so that boarding can be carried out as efficiently as possible. During the boarding process, in addition to the mentioned documentation, visas are often required for countries that require it for the citizens of the Republic of Croatia, so through Internet technologies unhindered communication with embassies of countries where the seafarer potentially goes to work is provided, various modes of transport to the place of embarkation such as airlines and the issuance of airline tickets. In addition to all the above processes, the emphasis should be on safety. Internet technologies, like other types of technologies, have great advantages and disadvantages, and they are, in this case, various technical difficulties or security (hacker) attacks, and the possible loss of uninterrupted communication or data loss, or leakage of confidential information of staff involved throughout boarding process, through vessel data, to mutual communication which sometimes includes private communication in the case of companies that take care of private yachts and requests that can be sent by the yacht staff. However, modern tools achieve a high level of security through the work of various developers and their software solutions, i.e. programs for protection against hacker attacks and viruses.
