    Boat Mail

    The reason you have not had a reply to this might be because Boat Mail are under new ownership and people are reluctant to recommend them until the new management has proved themselves. For my part, I have had a couple of minor queries since the new regime took over, and found them very helpful and efficient on both occasions so I have no hesitation in recommending them. MB

  7. Quoted from <http://blog.iharder.net/2011/04/15/kalmyk-can-the-kalmyk-unseat-the-bowline-as-king-of-knots/> I am reading the book “On the Trail of Genghis Khan” by Tim Cope. He traveled for 3 years on horseback from Mongolia to Hungary. On page 437 he mentions a knot he describes as a reverse bowline. On his very first night he was taught this knot by a Mongolian herder. As he traveled across the Eurasian Steppe he found the same knot but with the name of the peoples who lived in the area. A Kazakh knot in Kazakhstan, Kalmyk knot for the Kalmyk people, and in Hungary it was called a Cumanian knot. He used this knot for everything So possibly not a Cumberland but a Cumanian knot??
