Classic Australian Wooden Power Boat Association

Can anyone timeline this boat for a friend of mine? It's supposed to be 1968 but we are suss on that due to the generator fitted and FB/EK Holden steering wheel 60-62.
We are thinking it might be a repower to a red with dog clutch later in its life. All marinising gear on it is Tawco including the dog clutch.

This boat looks similar to screwit.
How long is she and how wide is the beam.

Hi Ross,

The boat is 4.7 mts long and 1.7 at the beam.

Same size but has extra ribs on inside hull next to engne and stringer ribs under hull but shape the same

So who was the manufacturer of yours Ross?

This boat and Classique were built on the same principle with those internal ribs and external stringers. I have only seen photos on the Internet and eBay of two others.
