The February 2019 JRA Hall of fame article is going to feature Hans and Golden Wind. There were two versions of Golden Wind, the first, a standard Liberty with a schooner rig, and the second modified by designer David Thomas for Hans, with a single carbon mast and battens by Carbospars. The mast pivots at the coachroof and the heel swings up through the anchor well, to make it easy to raise and lower alone. Both rigs were designed by Sunbird Marine. There are some technical details of the boat's construction and rig in some early JRA newsletters, which may be accessed online. There isn't a detailed sailplan, however. Hans is not able to provide information about this as he is unwell,and Sunbird Marine ceased trading after the untimely death of Robin Blain recently. However, the boat is now owned by Hans's good friends, JRA members, Margit and Andreas Vogt, who may be able to answer some of your questions.
