Looking for seabird info

[goodidea28]

I own a 1972 Seabird 28 express fisher and I am looking for info on whether these hulls are a Ray Hunt design.I posted this on the Seabird owners forum and got no response, I then posted it own the Bertram site because the boat looks idendical to the Bertram 28.I was told that the Bertram 28 was a Napier design, he was aparently the designer at Bertram after Hunt, but he did'nt know about the Seabird.Can anyone shed some light on this or tell me where I can get info on these boats?Thanks
