Used Seacraft

[marsh island]

I recently looked at a used 20 Seacraft hull with Identification with 70ish # in it. I found this hull to be strange in some ways. The seacraft name was in white color and the boat was an olive color. I have always read that the 70's boats were overbuilt but I found that the exterior walls and sides were very flexible much more than normal. I will purchase a 20 or 23 seacraft in the near future. I just didn't see the quality built in this hull. Maybe I was looking for something that was not there either. Can anyone tell me if this color is an original color and what years did they have white lettering? I have been in a 23 Sceptre and it was a tank. Was it that it was a 20?
