    Opis:
    This paper presents the problem of the “know-how” needed by the operators of vessel traffic supervision, monitoring, advisory and safety zone management systems required and maintained by marine navigators on their ships. The problem of the proper and correct interpretation of these systems is raised. Different types of ship safety zones, concerning both anti-collision and navigational purposes are presented, introducing the concept of hydrographic ship domain. Anti-collision and hydrographic domains were compared in order to establish mutual dependence. The factors influencing the two types of ship domains were analysed. The author proposed their merging and replacement with one universal domain, discussing its advantages and disadvantages. The analysis of the factors influencing the shape and size of such ship safety zones in conducted. The results in the different phases of research were presented and conclusions were drawn.

    Opis:
    This paper presents the research results on declarative ship domains in restricted areas. The research was conducted for vessels of different sizes and speed relations. In order to determine the declarative ship domain, data were collected in the form of questionnaires. The influence of ship length and speed on the size and shape of its domain were analyzed. The detailed processes of data development and further approximation are shown. Declarative domains for ships of different sizes and speed relations are compared. As a result of the research, a mathematical model of a declarative ship domain showing the elliptical shape of the domain is presented. The intermediate and summary research results are presented and conclusions drawn.

    Opis:
    Bezpieczne prowadzenie statku wymaga ciągłej identyfikacji i oceny sytuacji nawigacyjnej. Ocena bezpieczeństwa statku własnego sprowadzana jest często do ustalenia i obserwacji stref wokół statku. Pojawienie się obiektów obcych w tych strefach powoduje powstanie zagrożenia bezpieczeństwa nawigacji i wymaga jego oszacowania oraz podjęcia odpowiednich przeciwdziałań. Innym podejściem jest sytuacja, w której zachowanie odpowiedniego poziomu bezpieczeństwa nawigacji wymaga nawigowanie w ramach ustalonej strefy (np. strefa rozgraniczenia ruchu). W artykule przedstawiono różne rodzaje stref bezpieczeństwa statku oraz ich przeznaczenie.
    Ship's safety requires continuous identification and assessment of the navigational situation. The assessment of own ship's safety is often reduced to watching the established zones around the ship. The safety level is decreased when another object disturbs the established zones, which requires evaluating the risk and making adequate countermeasures. The situation when we have to maintain an adequate level of safety leads to another approach, i.e. it requires navigating the ship within an established zone (traffic separation scheme). In the paper different kinds of ship's zones and their purpose are presented.

    Opis:
    Navigational charts are a basic source of information for seafarers. But how accurate and reliable are they? How much trust and confidence can be put in them? Unfortunately, the answer is not so simple; it is far more complicated than merely saying that one chart is accurate and reliable while another is not. However, any seafarer navigating in unfamiliar waters should have the necessary skills. It is a great challenge – some may say an impossibility – to keep the thousands of navigational charts up to date. But exactly how out of date, how inaccurate, are the chart data? Chart users will have a better idea now that the Hydrographic Office is gradually implementing a new chart feature called the Zone of Confidence (ZOC) box which replaces the Source Diagram that is currently in use on large-scale charts. Source Diagrams, and now the improved ZOCs, assist seafarers in assessing hydrographic survey data and the associated levels of risk of navigating in a particular area. According to the new edition of the International Hydrographic Organization (IHO) specifications, S-4 navigational charts will provide more information on ZOCs. The current paper discusses these new regulations.

    Opis:
    Navigational charts are essential tools for marine navigation. But how accurate are the navigational charts that we use when going sailing? Do we really know how much faith can be placed in them? All charts, whether paper or electronic, contain data, which varies in quality due to the age and accuracy of individual surveys. In general, remote areas away from shipping routes tend to be less well surveyed, and less frequently, while areas of high commercial traffic are re-surveyed frequently to very high levels of accuracy, particularly where under-keel clearances are small. It is quite accurate to consider a chart as a jigsaw of individual surveys pieced together to form a single image. Having the necessary skills to determine how much confidence should be placed in the surveys, which combine to form a chart, should be a requirement for any sailor venturing into unfamiliar waters. When the International Hydrographic Organization (IHO) developed the S-57 standard for Electronic Navigational Charts (ENCs), this problem was recognized and it was decided that the quality of survey data used to compile ENCs had to be encoded within a composite data quality indicator ‘Category of Zone of Confidence’ (CATZOC) to assist seafarers in assessing hydrographic survey data and the associated level of risk of navigating in a particular area. According to IHO S-67, the accuracy of Electronic Navigational Charts is not impressive and leaves much to be desired. The author discusses these apparent shortcomings of ENCs and present erroneous approaches to this problem, so common in the seafaring community.
