Over the years Rodriguez triple-screw shallow-draft towboats have won a following in the shallow waters of the Mississippi River estuary. Many of these boats are the distinctive aft-cabin Lugger-type of vessel.

Recently Mid-River Terminal of Osceola, Arkansas has taken delivery of a new design towboat from Rodriguez. With a conventional forward-house pusher configuration, the new 70 by 30-foot MV/ Dianna Lynn utilizes the same propulsion as the Lugger tugs. This is composed of three in-line 6-cylinder Cummins QSK19 engines, each delivering 660 HP. Each engine turns a 66-inch stainless steel propeller through ZF gears with 6:1 reduction. The combination gives the 1,980 HP-towboat an eight-foot operating draft.

The bank of three QSK19 engines affords full redundancy.

The wheelhouse has a full 360-degree view with large windows and is set atop two accommodation decks and a half deck that also serves for bridge electronics support. This gives the towboat a 31-foot eye-level, with full tanks, for working high barges. Steering and flanking rudders are controlled by wheelhouse levers with mechanical shafts through the houses and connected to the hydraulic actuator valves in the upper engine room. A set of push knees and deck winches with cheek blocks facilitates barge work. A pair of 55 kW gensets meets the boat’s electrical requirements.

The wheelhouse has a 31-foot eye-level with excellent visibility all around.

Zero discharge tanks, built integral to the hull, provide storage for treated sewage and all drains. A separate tank handles waste oil.

The M/V Dianna Lynn is the fourth boat in the Mid-River Terminal fleet, all of which are Cummins powered. Owner Rick Ellis said by phone, “We wanted the three engines for redundancy so that even if we loose an engine we still have over 1200 horsepower.”

The new boat will be primarily involved in fleeting and harbor work, “Rodriguez did a great job and it is a great handling boat,” Ellis added.
