Non-road fuel consumption and pollutant emissions FOEN 2008 56 6.6 Marine machinery The inventories of ships and boats in Switzerland are well documented thanks to the data recorded by the Swiss Federal Statistical Office, the relevant cantonal authorities and the province of Vorarlberg. The statistics kept by the latter record the inventory of boats in the region of Lake Constance, differentiated by engine-power classes. Since no corresponding statistics exist for Switzerland’s lakes, the size distribution of boats for Lake Constance was assumed to be representative for Switzerland’s bodies of water. The distribution of passenger ships, ferries and cargo vessels/barges by engine-power classes was made on the basis of information provided by marine transport operators. The fact that many vessels are equipped with more than one engine was taken into account in the distribution by engine-power classes. The mean engine power in the class > 560 kW was based on the effective motorisation of ships on Switzerland’s lakes, and was around 770 kW in 2005. The operating hours of boats were estimated by specialists in the workgroup. The utilisation of passenger ships was based on information provided by operators, while the corresponding figures for cargo vessels/barges were based on information provided by the two Basel cantons. Inventory Figure 26 (top left) shows that 99% of motor boats on Switzerland’s lakes are hired or privately owned boats and yachts, while the remainder are used for professional fishing and commercial operations. In addition, in 2005 there were 142 passenger ships, 14 steamboats, 8 ferries and 240 cargo vessels/barges in operation. This list does not include military vessels, which are included in the category of military machinery (see section 6.8). Operating hours and their chronological development from 1980 to 2020 In the marine machinery category, the average annual operating hours vary enormously. While recreational craft (yachts, hired and privately-owned motor boats) are only used sporadically (average = 30 hrs p.a.), the average operating hours of ships and boats used for professional purposes are very high: 500 hrs p.a. for fishing boats, cargo vessels/barges, etc., 1200 hrs p.a. for passenger ships, 3500 hrs p.a. for ferries (numerical values, see Tab. 40 on page 140). As we can see from the bottom half of Figure 26, the proportion of vessels equipped with a petrol engine has fallen slightly. No significant changes are anticipated with respect to the inventories of ships and boats.
