Starman today is your lucky day! For the longest time my boat was "MerCat" on one side and I had to jump through many hoops to track down the actual company that produced the decals for my boat.
Contact Cassandra Bakeberg at Universal Products and she will hook you up.
Warning: For my boat she said they could only produce a full pair for $385 or more pairs for slightly discounted prices. Depends on how much you want that factory look, like I did.
