The Miss Sheila is a 70 foot, 1,350 shp pushboat, constructed in Mississippi Marine's stock boat construction program.

Mississippi Marine currently has an 85-foot by 30-foot by iO-foot, 6-inch, 1,800 shp, pushboat under construction in its stock boat construction program. This vessel is scheduled for completion in the fourth quarter of 1981.

The vessel carries 17,400 gallons of fuel oil, and is equipped with fuel oil fill stations, port and starboard of the main cabin. The vessel has a potable water capacity of 6,700 gallons and 600 gallon lube and slop oil tanks. The vessel is arranged with a main cabin providing an enclosed steering room aft, separate generator compartment, upper engine room and forward quarters and galley area. The Texas deck provides sleeping accommodations for six in three separate staterooms, while the main deck has a single double stateroom. An enclosed stairway provides access from the main deck to the Texas cabin and up to a large raised wheelhouse. The wheelhouse provides 360-degree visibility and a 27-foot eye level.
The vessel is powered by Twin GM Detroit Diesel 12V-149s—providing a total of 1,350 shp—and is equipped with Twin Disc MG 540 (7-to-l) reduction gears. The vessel is equipped with 7-inch- diameter shafting which are fitted with S t u rm sleeves.

The M/V Miss Sheila is designed for both harbor and short line towing service. She is equipped with two Nabrico, model 20-11-EH, electric/hydraulic winches. Winch controls are located on the main deck and in the wheelhouse. The hull has seven 36-inch Nabrico kevels, two Nabrico roller chocks, and four buttons. The 12-foot-high pushknees are equipped with heavy rubber bumpers. A hand winch boat davit has been installed on the aft deck for raising and lowering the vessel's launch.
Mississippi Marine's shipyard is currently very active. In addition to the stock 1,800-hp pushboat previously described, Mississippi Marine also has under construction a 143-foot offshore geophysical vessel for Tidewater Marine Service; two 2,400-hpclass p u s h b o a t s , and several smaller vessels.
