How thick is my hull bottom? 1969 20sf

I'm just curious. I did a search but doesn't seem like anyone ever asked the question.

I'm not sure about yours, however just for grins I took this picture of the piece of my hull when I drilled the 3 1/2" hole for my transducer.

Good to know.

From the 1969 Boating Magazine on the 20' Seafari, the following sketch represents the 4 stringer hulls. Don't know what changes Potter made when he switched to the 2 stringer version.

So less than a 1/4" ok. DonV that is from a 23footer correct?
