Cute boat. Reminds me of my 'Viking' 14' day sailor that was made sometime in the 50's - one of the first fiberglass boats. Your boat looks much newer then my day sailor.
It is quite possible that the main sail from one of Sailingdog's Daggers was put on your boat.
I think that your boat is a Chrysler Lone Star 13 as seen here:
