180' Aluminum Waterjet

| Conrad Aluminum, LLC of Morgan City, Louisiana contracted with the widely recognized naval architecture and marine engineering firm of A. K. Suda, Inc. to design a crew/supply boat that is faster, carries more deck load and more passengers, and was still delivered at an economical price. The result is the 180' high-speed aluminum waterjet crew/supply boat, M/V Mary Grace. |

Innovative DesignThis ground-breaking design is based on sound engineering and provides equal or greater levels of safety and strength than required by ABS and U.S. Coast Guard rules. In maintaining the USCG Subchapter T designation, the vessel has been designed without the use of deep tonnage frames or tonnage openings throughout the vessel. This technique results in a savings of aluminum in the construction process. The savings in weight and the improvements in hull form have resulted in a higher speed and higher deck load capacity (540 lbs./sq. ft.) |

FeaturesThe 180' vessel is powered by four (4) engines and is capable of attaining speeds in excess of 30 knots. The design package can be tailored to suit equipment from the owner's engine manufacturer of choice. The design also offers the flexibility to allow the owner to choose between conventional propeller propulsion systems and waterjet propulsors.The cargo deck offers 40% more deck space than other vessels this size and can carry about 38% more Short Tons than competing vessels. The vessel design provides what we believe is unprecedented flexibility in loading. The entire deadweight of 280 Short Tons can be carried on the deck. The design also provides for larger crew accommodations. With a more spacious hull, passenger seating can now be on two levels…. in the hull and on the main deck. Passenger seating can accommodate over 70 passengers and there is still comfortable berthing for 9 passengers. The elimination of tonnage frames also means that tank areas are unobstructed by tonnage frames and thus are easier to clean. |
