The best way is to compare what year the boat was built and where. If it was built in Taiwan from 1983-1985, you have a Seastar built by Mao Ta. We think the boats built by Mao Ta in 1986 were called a Mao Ta 46. One easy way to find common ground among this name confusion is to remember the name given to the design by Ted Brewer, Oceanic 46 . But now it does, with owners on both coasts of the US and in Canada.
Owners exchange information daily via our mailing list.
Search engines have just begun to list the POG home page. We are listed on many sailing sites under owners associations, and are submitting our group to any site we discover that doesn't currently list us. As a result, we have been successful in finding a new owner every few weeks. And then there is Ted Brewer. He provided much of the history information on this page.
