What this be?

[tsubaki]

This is a project of my fathers.
The transom and other stuff has been redone some time ago and the boat has been sitting a while.
When the transom was redone they glassed over the HID numbers and also painted over the capacity plate so we currently have no idea what the boat is.
The colors are not original, best we can tell it was white on white.
Daddy said he had owned another one just like it and thought the name was "Pioneer".
Ya'll got any ideas??
