Perhaps this gives some clues regarding the design:

Why would anybody want to paint their boat in camouflage? You would think that it would be in the owner's interest that other vessels would be able to see his boat. In addition, what is the point of that ram bow? Ram bows are a stupid idea because the boat driver cannot see the forward extremity of the vessel. In other words, it is an invitation to an accident while docking or undocking.
