My '70 20 SF did not have the SeaCraft logos on it and while it did look nice without them, I decided to have some made for it. Before I had them made I bought a set off of Ebay. The Ebay set turned out to be too large. Instead of letting them go to waste, I decided to re-tag my 14ft Starcraft tin boat.
Hopefully it doesn't upset the SeaCraft gods...
I also had a local sign shop make up some proper sized tags for the real SeaCraft. Not 100% true to the original, but I like them.
