If he's layering a multi-color cut vinyl decal, kudos to him, that's a job I wouldn't take.
My point is, sadly, he's gone the route of thinking he can print his own vinyl decals on an aqueous printer and use it out on the water as a replacement of what I print on my Roland VersaCamm... Not to knock anyone, but I think there's a huge difference when you're talking about equipment cost of $800 vs $15000!
