The link above directs readers to a PDF paper published by the Inland Waterways Association in which they theorise about potential greener propulsion methods for boats in the future.
This is not a technical paper and is laid out with clear headings and subheadings for ease of reading. The Boating Association are just wanting to get you thinking. If anyone has ideas regarding greener propulsion for steel or fibreglass crafts please feel free to let us know by commenting on this post, so we can see that it is passed on.
Alternatively, if you prefer to voice your opinion privately feel free to email it to your chairmen at firstname.lastname@example.org
