Sailing Subgroup and expertise
George, I've let User: David Finn know about this article. He knows much more than I do about sail rigs.
We don't have a Transport Workgroup at present, but most such things go into engineering. There is also a marine navigation subgroup, as well as marine electronics, things about which I do know something. Howard C. Berkowitz 10:57, 27 April 2011 (CDT)
