Wind propulsion is well known and has propelled ships for millennia. However, with the advent of fossil-fuel powered ships, wind energy lost its importance for cargo transport almost 100 years ago. Rising fuel prices, and a society more aware of the consequences of CO2 emissions, fuels the revitalization of this energy source, and a variety of wind-assisted propulsion systems are on the market today. Key factors for the success of wind-assisted propulsion are discussed, and a case study for a multipurpose vessel is used as an illustration.
