What year is my boat?

[goodtry]

Just joined today and the first question I have is what year was my boat manufactured? There is no Hull Stamping, but there is a foil plate mounted on the engine cover base.

It shows the boat as a 20' FIO with a serial number of 1294.

Any help would be greatly appreciated.

Also needing to replace the wood hatches up front and along each side of the inboard. These could easily be made from marine plywood but could be made from a polymer? Any suggestions on this would also be appreciated.
