Wind Propulsion Tech for Expedition Yachts: Wingsails, Kites & Flettner Rotors

The International Maritime Organization has mandated that large ocean-going ships must cut their carbon emissions by 40% by the year 2030. As a result, the shipping industry is embracing wind-propulsion as the most viable near-term solution. They, along with government agencies, are financing the R&D and manufacturing of wind-propulsion solutions. Wind-assisted commercial shipping uses modern technologies like rotor sails, rigid wings (Wind Wings), and suction wings to harness wind power, significantly cutting fuel use and emissions (5-50%) by supplementing engine power, driven by strict regulations and economic benefits, with systems like Anemoi's rotor sails and Airseas' Seawings already deployed on cargo vessels. These systems offer a practical, cost-effective way for the industry to decarbonize, transforming old sailing concepts into high-tech solutions for a greener future. According to DNV: "Wind-assisted propulsion system (WAPS) technologies have gained significant attention in the shipping industry as a means of reducing fuel consumption and emissions. These technologies harness the power of wind to supplement the propulsion of a vessel by generation of aerodynamic forces. They have the potential to significantly improve the efficiency of shipping operations and make a meaningful contribution to the decarbonization of the industry, as wind is an inexhaustible, free, zero-carbon energy source. Sail systems Several different sailing technology concepts have been or are being developed, including rigid or soft wing sails, Flettner rotors and ventilated foils, or kites. Most modern systems now utilize state-of-the-art intelligent control and automation systems to operate in a safe manner and without the requirement for additional crew. A combination of advanced aerodynamics, automation, computer modelling and modern materials is unlocking a new generation of innovative sail systems for ocean-going ships." For our new build, we want a proven sail-assist technology that is readily adaptable for our specific mission and vessel profile. We need to consider, amongst many criteria - size and weight vs propulsion delivery, will the rig fold-down, is there a service and maintenance program from the manufacturer to support us. This video will shed some light on this highly important component of our new-build process, and maritime industry developments in general.
