Cruising tourism is becoming increasingly popular, the number of cruises having seen a continuous increase since the 1970s. In Croatia as well there is an upward trend in the number of cruise passengers and ports. Of all Croatian ports, it is the port of Dubrovnik that has had the most calls by foreign cruisers. The paper analyses the available statistical data on the maritime cruise market in Europe with special reference to the Mediterranean countries. In the national context, a presentation of cruise traffic in the port of Dubrovnik is given. Although this type of tourism contributes to the development and improvement of the economy, it also has a negative impact on the environment through air pollution by CO2 emissions, subsequently affecting human health as well. The authors investigate the level of CO2 emissions in the area of the port of Dubrovnik. CO2 emissions were calculated based on cruiser activity, the calculations being based on CO2 emissions for three ship navigation modes - slow steaming on arrival and departure, manoeuvring on arrival and departure, and for a berthed ship. The aim of the research was to provide a better insight in the emission inventories in this area. This research can also be applied to other port areas.

The problem of underwater hull fouling has been mostly noticed by the pleasure boat owners when reducing the boat speed. In order to decrease the fouling of the underwater part of the hull, antifouling paints have been used. Some kinds of antifouling paints have become a serious environmental problem due to its very harmful effect on marine organisms and also, indirectly, on humans. Scientific research conducted in this domain has confirmed contamination by toxic compounds as a result of the usage of antifouling paints over long period of time. The paper is focused on underwater hull maintenance, especially when applying antifouling systems on pleasure crafts owned by tourists and local residents, in the example of the village ports of a small island. A survey was conducted among the residents who use ports to determine their knowledge regarding the harmful effects of biocidal coatings and the possible harmless maintenance of the underwater hull part. This paper aims to indicate the necessary equipment and procedures in the two small local ports in order to maintain pleasure boats in environmentally acceptable manner.
