Lance, you can also contact a company called Decal Grafix, they make boat decals among other things. You can get a Moomba decal made to size, anywhere between 5 and 8 foot. I have two pictures of decals he has made - I can email them to you if you like - just post your email address..
otherwise - contact Marco with Decal Grafix directly at:

I have not purchased with this guy before - but he seems pretty legit..
