SWER is also used extensively in Brazil where it is termed “Redes Monofilares com Retorno por Terra” or “MRT”. There are detailed standards and drawings available in Brazilian Portuguese that would be transferable to other Portuguese speaking countries such as Angola and Mozambique.

“The best nations are those most widely related; and navigation, as effecting a world-wide mixture, is the most potent advancer of nations.”
