    Greenheart say: "The Idea (of our project) is to create a new type of low-cost, zero-emissions small cargo ship that uses environmentally clean and sustainable sail and solar power, to provide needy coastal communities around the world with an affordable means of transport. Such ships can help impoverished coastal and island regions improve their standards of living, while preserving their traditions and protecting the environment. In addition, we will use the publicity generated by such an inspiring enterprise, to promote Fair Trade, renewable energy and international cooperation." Read more.

    Shame they haven't gone for a junk rig, but well worth a read.

    With all the solar panels, li-ion batteries, lasers, motors and other high tech fixes, I suspect this would be less sustainable in the "impoverished coastal and island regions" than they imagine, unless it is externally funded, built, rigged and maintained.

    The Three Amigos ('From A to B, Emission Free'] in this forum sail shipping plan seems a bit more practical with their old-school approach of wood and rope. 

    Boldger did a "impovershed, coastal" cargo ship as well, worth a look if you're interested in this type of thing. Not a "fully battened lug"-type junk but a hybrid fully-battened with sheetlets gaff. Has anyone sailed one of these rigs before? I think Boldger drew them a lot.

    Hi Karlis. Thanks for those comments and the Bolger link. Let's see what others think.

    The lower part of the mast looks to be heavily built and double as the part of a crane to handle cargo and would be key part of the design. It hard to picture how a junk sail would allow that. The gaff sail then would have to attach on some kind of track, I think.  I wonder how the battens were to be attached there. He may have had had a simple low tech solution for which he was well known. When I converted my O'day 23 in 1994 he designed the mast, a basic tabernacled four sided mast from dimensional lumber.  In the letter that accompanied the plan he said that he didn't know much about the junk rig "but some very well respected people swear by it."
