Thanks guys for the replies!
The placement of the hatch leads me to believe it's intended for some kind of open ocean racing.
Barney ~ That would explain why the scuppers are so large for such a small vessel.
They measure about 6 inches x 4 inches. See attahed image.
If not there look just below the rub rail on the srbd quarted at the transom.
Charley ~ We scoured the transom ... it appeared clean as a whistle -- nice and smooth, with
nary a trace or 'ghost mark' of where the HIN would have been. We will check the Strbd Qrtr
and will let you know what we find. In the past, we've searched the MIC data base on the
Coast Guard site for other boats we were trying to identify -- but with all of those, we had
a valid hull number, making it a simple task to find the manufacturer.
The research continues ....
