Full speed ahead.
Typical applications for medium duty boats cover goods and passenger transportation as well as
escort and patrol duties at sea. MAN marine diesel engines perform these tasks reliably and effi-
ciently with high power outputs. With ratings from 400 to 1,400 mhp they have powerful accele-
ration and high tractive power. MAN engines meet the current emission standards and are envi-
ronmentally friendly. The worldwide service network ensures minimal maintenance effort and a
customer-oriented service.
