This is all I have time for this afternoon, but I'll get back to it, soonest.
http://www.mat.uc.pt/~helios/Mestre/Novemb00/H61iflan.htmAdditionally, from the introduction of "The Cruising Multihull", by Chris White, we find; "For thousands of years, multihulls were the vehicle of choice throughout much of India, Indonesia, Malaysia, southeast Asia, parts of China, the Philippines, Polynesia, Melanesia, and Micronesia." Hardly definitive proof of an Indo-Polynesian sailing tradition, but a reputable source never the less.
Absent a common cultural link, what then, spontaneous generation?
