Triple screw lugger tug

Over in the USA, in the section of the Gulf Coast where the Mississippi meets the Gulf, shallow draft lugger tugs have been earning their keep suppling the near shore oil industry. But their size has been limited by their draft which is, of course subject to the prop size as much as the hull depth.
