21 November – Ecoclipper – Project Update

EcoClipper is introducing the prototype 500 cargo/passenger sailing vessel.

The innovative design cooperative Sailvolution and specialised shipping company EcoClipper have worked together with a broad group of advisers to design a prototype cargo/passenger sailing vessel. Their aim is to scale up the success of current sail cargo vessels and offer worldwide emission free transport.

The multi-purpose design makes it possible to serve two entirely different markets. First, the intercontinental freight market for companies who do not want to compromise on environmental considerations with their logistics. Secondly, the market for long-distance transport of paying passengers. The latter could compose of a diverse group of people who decided to take an emission-free sailing vessel instead of flying for romantic or practical reasons.

The EcoClipper500 prototype will be the first newly built deep-sea sailing cargo vessel not propelled by mechanical means in the 21st century. EcoClipper came up with this design after analysing the experiences and market conditions of the current sail cargo vessels in operation. Her size was decided according to an analysis to determine the smallest size sailing vessel still capable of being financially viable and profitable on long ocean routes.  DOWNLOAD FULL UPDATE EcoClipper is introducing her prototype 500 cargo passenger sailing vessel.

IWSA Asia Autumn Tour

Asia is a key market for shipping and central to the shipbuilding industry. While IWSA and our members have been actively engaged with the region over the past few years, we feel it is an important time to start raising the Wind Propulsion profile in the region in preparation for the increased interest in decarbonisation technology solutions for the world’s fleet over the coming year. Wind propulsion technologies can deliver significant fuel and carbon savings using today’s technology, harnessing energy delivered to vessels at the point of use, without storage or infrastructure requirements and after the initial CAPEX is covered, then only standard maintenance OPEX – fixing that percentage of fuel cost at ZERO for the lifetime of the vessel. This is the message we are bringing to the Chinese, Korean and Japanese markets over the next 2-3 months
