Just dropping a line to say you've got another Pearson owner following the thread. I own a Pearson 30. Does anyone know how one may be able to find out a boat's original hull color? Is there Pearson list by serial number that has this information?
Since Pearson ceased operations so long ago, I doubt very much that such a list could now be found.
If you really must know, I recommend removing all the bottom paint in a small section and then scratching carefully until you get to the original gelcoat. My bet is it was white. Or, next time the boat is out of the water, remove one of the thru hulls and examine the cross section of the hull with a magnifying glass.
