One of the boats that MetalCraft Marine delivered this year is the 85'×26'×12' aluminum firefighting, rescue, patrol boat Monjed 2. The boat, which was delivered to the Kuwait Fire Force with a 4' draft, was designed by Walker Marine Design Ltd. in the UK.
Because of the uniqueness of the boat’s operational location, MetalCraft started looking at outside designs that were used in severe sea state conditions that could make good speeds and carry heavy loads.
MetalCraft decided on a Walker Marine design used on North Sea windfarm maintenance boats, most of which are also semi-displacement designs, which means very little hull motion and a comfortable ride for the service techs, according to MetalCraft partner and contracts manager Bob Clark. “Seasick service techs don’t work very well.”
Neither do re ghters.
“MetalCraft started on preliminary designs back in early 2015. Several concepts did not y due to the instability of shooting 12,000 gpm from 45 feet above the water,” said Clark. “Even a catamaran design would need to be very large and very heavy with a super-low center of gravity to support the force of 12,000 gpm from the tower monitors.
“Of course, this is only one of the stability concerns,” he continued. “The boat would also need to handle severe seas if a re occurred during a storm event. MetalCraft started looking at outside designs that were designed around severe sea states that could make good speeds and carry heavy loads. This led us to the wind farm boats of the North Sea.”
Monjed 2’s design has very tall twin hulls wide enough to house large diesels and lots of re ghting equipment. Several dozen of this Walker model are in service. The key to a mature design, like the shipyard’s Firestorm model, is its heritage, as each subsequent build incorporates new and better developments into the design, Clark said.

two MTU 10V 2000 M86 diesel engines, producing 1,360 hp at 2,450 rpm each. The mains connect to twin Marine Jet Power DRB 500 waterjets through ZF 665 two-speed marine gears. The propulsion package gives the boat a running speed of 27.8 knots. For added maneuverability, the boat is tted with a Sleipner Side-Power SH550 bow thruster and Imtra Exalto wipers.
MJP took care of the controls and steering responsibilities with its Jet Master 1 package. There is also a Raymarine Axiom, Setcom, and Teledyne FLIR electronics suite aboard the boat.
Capacities include 1,200 gals of diesel fuel, 100 gals. water, and 800 gals. re ghting foam.
The Monjed 2 features two Jason re pumps, discharging 5,000 gpm each through telescopic monitors that extend 40' above the deck.
Ship’s service power is the responsibility of twin Kohler gensets.
The MetalCraft FireStorms models are evolving. And that’s signi cant. The FireStorms like the Monjed 2 have improved over the boats built back in 2003. Importantly, Clark notes that all those boats are still in operation.

DOUBLE DOWN
Charter boat is built to new Coast Guard regulations.
By Ken Hocke, Senior Editor
Brix Marine, Port Angeles, Wash., delivered the 48'×18'×4'10" aluminum overnight charter fishing boat Double Down to Soldotna, Alaska-based Big Dan’s Fishing Charters in April. The boat was designed by the shipyard.
Because of the 2019 Conception tragedy in California, Brix worked closely with the Coast Guard to make sure everything was up to the agency’s new standards.
The Conception was a 75', woodand-fiberglass passenger vessel. On a Labor Day weekend dive trip, a fire broke out which engulfed the boat and led to its sinking. It resulted in the deaths of 34 people.
The Coast Guard and NTSB found that the boat’s electrical system was overwhelmed with the large number of electronic devices that passengers had plugged into the system.
The Coast Guard cited the captain for failure to have a night watch or roving patrol, to conduct sufficient fire drills, and to conduct sufficient crew training.
“Since the Conception fire, we worked really close with the Coast Guard to make sure everything was up to the new standards,” said Capt. Charlie Crane of Brix Marine.
From the tragedy came a bevy of new regulations concerning overnight charter boats. Double Down was built to those new standards.

Builder: Conrad Shipyard Designer: Crowley Engineering Services Owner: EJE Dredging Service Mission: Address signifi cant shoaling that occurs in various channels and inlets throughout Dare County, N.C. Length: 156'3" Beam: 35' Depth: 10'9" Draft: 9'5" Hull and Superstructure: Steel, aluminum deckhouse Main Propulsion: (2) Cummins QSK-19DM Thrusters: (2) ZF ATZ 4111-SM DA-FP stern mounted, (2) Wesmar V2-26SS Ship’s Service Power: (2) Cummins QSM11-M 250 kW Hopper Spoils: 512 cu. yds. Delivery Date: August 2022
Dare County, N.C., and EJE Dredging Service took delivery of the Miss Katie, a shallowdraft 156'3"×35'×10'9" hopper dredge built at Conrad Shipyard, Morgan City, La., in August.
Wanchese, N.C., is the dredge’s homeport.
Construction on the dredge began in March 2021. Crowley Engineering Services designed the vessel with a 9'5" draft.
In 2019, Dare County approved a contract for the construction and operation of a new shallow-draft hopper dredge to address the signi cant shoaling that occurs in various channels and inlets throughout the county.
The Miss Katie “will be a game changer for watermen in Dare County,” said Dare County Board of Commissioners Chairman Bob Woodard. “It’s absolutely critical that we have the resources in place to properly dredge our channels and inlets that these watermen depend on as their highway to get to work every day, and thanks to the county’s partnership with EJE Dredging
The Miss Katie has a capacity of 512 cu. yds. of dredge spoils.
and the arrival of Miss Katie, we’ll be much better equipped to do just that.”
Greenville, N.C.-based EJE Dredging owns and operates the dredge.
The shallow-draft, split-hull trailing-suction dredge’s main propulsion comes from twin Cummins QSK-19DM diesel engines connected to two ZF ATZ 4111-SM DA-FP sternmounted azimuth thrusters, each featuring depth adjustment. The dredge’s running speed is 10 knots.
The Miss Katie features a ZF ThrusterCommand AT control system.
In addition to providing controls for the two Wesmar V226SS thrusters, the control system provides follow-up steering and propulsion control, as well as independent backup and emergency stop systems.
The dredge features twin 5,000-gpm dredge pumps and has a capacity of 512 cu. yds. of spoils.
One other signi cant aspect of the new dredge is that it was speci cally developed and designed for the waters it will work.
“The Miss Katie has been speci cally developed and designed to ensure she will be able to safely navigate the channels and inlets of North Carolina,” said Jordan Hennessy, vice president of EJE Dredging. “The split-hull con guration will allow spoil discharge in shallow waters, thus preventing the vessel from grounding on her own hopper load.”

APALACHICOLA
The fi rst Navy EPF with an autonomous feature.
Austal USA photos
Apalachicola is the 13th EPF, formerly known as joint high-speed vessels, the fi rst of which was delivered by Austal USA in 2012.
By Ken Hocke, Senior Editor
The 338'×93'6" multihull, aluminum Spearhead-class expeditionary fast transport vessel Apalachicola is part of the Military Sealift Command’s Sealift Program. Apalachicola is the 13th EPF, formerly known as the joint high-speed vessel, the rst of which was delivered by Austal USA, Mobile, Ala., in 2012.
If you’re thinking that EPF doesn’t line up with expeditionary fast transport, you’re not the only one.
The catamaran vessels have performed humanitarian assistance, disaster relief, maritime security, surveillance, command and control, counter narcotics, and additional operations around the world.
So what makes Apalachicola different from its predecessors? Austal USA was contracted to design, procure, implement, and demonstrate the Apalachicola as an autonomous platform, allowing the ship to operate autonomously while retaining the capability for manned operation, reducing cost and centralizing ship operations to the bridge. Successful autonomous capability required modi cations to Austal’s machinery control system and hull mechanical and electrical systems, integration of L3Harris’ mission and navigational autonomy systems, and General Dynamics Mission Systems’ autonomous cyber solution to create the Navy’s largest unmanned surface vessel.
“EPF 13 is derived from Austal USA’s mature Spearhead-class EPF high-speed, exible, multihull aluminum vessel design,” Austal USA President Rusty Murdaugh said. “Our team was able to leverage the platform’s core automation capabilities and develop a software and hardware solution to enable autonomous operations.
“Successful autonomous capability,” he continued, “required modi cations to Austal’s machinery control system and hull mechanical and electrical systems, integration of L3Harris’ mission and navigational autonomy systems, and General Dynamics Mission Systems’ autonomous cyber solution.” The result is the Navy’s largest unmanned surface vessel.
Main propulsion comes from four MTU 20V8000 diesel engines hooked up to four Wä rtsilä steerable, reversing waterjets through four ZF 60000 NRTH gearboxes, giving the Apalachicola a speed of 33 knots with 380 metric tonnes of cargo, 21 knots with a mission payload of 231 metric tonnes of medical cargo, and 10 knots in sea state 5.
Former U.S. Sen. Kelly Loef er, R-Ga., ship sponsor of the Apalachicola, christened the vessel, the second Navy ship to be named after the Florida coast city.
The rst Navy ship named Apalachicola (YTB-767), a Natick-class large harbor tug, was also built in

“Today we celebrate the christening of the 13th EPF with an Austal team of more than 3,000 employees,” Murdaugh said during the ship’s christening ceremony. “Apalachicola’s sisterships are successfully supporting naval commands on the U.S. East and West Coasts, along with forward deployments in the Middle East, Africa, Mediterranean, South America, and Asia regions. In the coming months, this highly complex, high-speed ship will join the others to support our great Navy.”
Other features include a crew of 36; a medical detachment that boasts three VIPs and one officer in charge; eight isolation/acute care medical beds; two operating rooms (one major and one minor procedure), 23 medical ward beds, 10 ICU beds, and eight isolation/acute care beds; an 11-meter (36') RIB launch and recovery system; and a hydraulic paint boom.
Austal USA is currently building the future Point Loma (EPF 15). The shipyard is also building several littoral combat ships (LCS) for the Navy at its Gulf Coast shipyard.
Former U.S. Sen. Kelly Loeffl er, ship sponsor of the Apalachicola, christened the expeditionary fast transport vessel on Nov. 13, 2021. It is the second Navy ship to be named after the Florida coast city.

New survey boat works the mouth of the Mississippi River.
Silver Ships
The new survey boat is custom designed for the Army Corps of Engineers to hydrographically map the mouth of the Mississippi River.
By Ken Hocke, Senior Editor
In August, Silver Ships Inc., Theodore, Ala., delivered the largest marine survey vessel of its series, designed for the U.S. Army Corps of Engineers Venice Sub Of ce in Venice, La.
The 49' Tobin is the latest expansion in Silver Ships’ Endeavor series of workboats.
Tobin is custom designed for the U.S. Army Corps of Engineers to hydrographically map the mouth of the Mississippi River. The missionspeci c vessel allows researchers to accurately and effectively obtain and document data on the river’s rapidly changing waters, data that will keep the waterway open and prevent obstructions to marine navigation. The custom vessel conducts condition surveys of the river to further the safety of marine operations.
“Tobin will join a fleet of vessels operating out of the USACE Venice Sub Office that works year-round to provide river condition data to vessel operators,” Jason Powers, director of business development for Silver Ships, said. “This data is essential to the safe and efficient transportation of goods up and down the Mississippi River.”
The vessel is powered by twin Caterpillar C18 Tier 3 engines each putting out 800 hp at 2,100 rpm.
The package gives the survey boat a top speed of 28 knots, which helps prevent research delays, which is important considering the frequent changes in Mississippi River conditions.
A single Caterpillar C2.2 Tier 3 genset provides 25 kW of electric power for the Tobin’s air conditioning, echo sounder, and other electrical needs onboard.
“Thompson CAT is proud to partner with Silver Ships for their power needs,” said Richard Tremayne, Thompson’s marine business manager. “Together our engineering teams have designed and built significant boats like Tobin over many years. High-performance power installations are always fun puzzles to solve with talented companies like the Silver Ships team.”

tion, Arid Bilge Series 4 system, Imtra Decca wipers, and Ayres paneling.
With speeds that reach 28 knots, the surveying vessel allows researchers to acquire data quickly and prevent navigational miscues caused by changes in the river bottom.
Additionally, the Tobin is equipped with state-of-the-art technology including the EchoTrac, E-20 survey system, which is the key component that allows the vessel to take survey measurements. The E-20 uses a single-beam transducer that charts river depths and monitors water changes that could be potentially hazardous to vessels traversing the river.
The vessel’s name honors Thomas G. Tobin, who worked for the Army Corps of Engineers New Orleans District for more than 30 years. A capable engineer and brilliant programmer, Tobin developed systems that automated the processing and mapping of daily navigation condition surveys collected. He was a part of the engineering division channel improvement team, and he achieved success with their automated design functions that ensure ef cient operations of the Mississippi River.
Tobin passed away in 2016, at age 54, after a battle with cancer.

GEORGETOWN HERITAGE
New passenger vessel pays homage to tradition.
By Ken Hocke, Senior Editor
Roudebush Yacht & Engine Works, Dundalk, Md., delivered the 80'×12'×5'6", 75-passenger berglass/ composite Georgetown Heritage Canal Boat to Georgetown Heritage, a group tasked with restoring and revitalizing the historic Chesapeake and Ohio (C&O) Canal that runs through Washington, D.C.’s historic Georgetown neighborhood.
Designed by D.C.-based Tridentis, the Georgetown Heritage Canal Boat has a 1' draft and is built to be pulled along by two mules. Its propulsion package contains two electric Torqeedo 10 FP motors, sparking 5.6 kW of propulsive power at 1,400 rpm. The mains are connected to Torqeedo 1937-00, 12.6"×11" 5-bladed propellers. The package gives the boat a running speed of three knots. Six Torqeedo 485000 batteries provide service power.
Christopher Addington, Tridentis’ program manager for the project, said the intent of the design is to provide as close a replica to a 19th century canal workboat, right down to the mules (with electric motor backup). The overall goal is to update from the original 19th century design in order to reduce

The canal boat has a canopy that covers the passenger deck, providing shade and protection from the elements. The canopy was designed to allow the operators to transit across the top of it, providing forward and aft passage separated from the passenger deck. As the boat enters and exits the canal locks at numerous points along the trip, the operators use wooden poles that are stored atop the canopy to position the workboat inside the lock doors.
The stainless-steel rudders (one on each end) are hand operated by a tiller. The forward rudder is lifted via block and tackle and tied off. The boat has a 560-sq.-ft. cargo deck.
In an age where tradition is many times seen as an inability to accept change, here we have the Georgetown Heritage Canal Boat because the Georgetown Heritage Group thinks upholding tradition is worthwhile. That’s signi cant.

Ferry operator gets back to operating without Covid-19 restrictions.
By Kirk Moore, Contributing Editor
New York Harbor commuter ferry operator Seastreak upped its game in December 2021 with the arrival of the Courageous, a 720-passenger aluminum catamaran built by Midship Marine, Harvey, La., that stretches by 7' the eet’s last 150'×40' acquisition, the Commodore, delivered in 2018.
Incat Crowther handled the design chores.
“It’s basically a sistership, but it’s a couple of frames larger,” said Seastreak president Jim Barker. The other difference is upgrades in passenger amenities and comfort. “It’s a couple of notches above any ferry boat I’ve ever seen.”
With steady increases in passenger volume and company growth, Seastreak of cials made the decision to go even bigger in 2019, stepping up from the 600-passenger capacity of the Commodore. As the Covid-19 pandemic struck in spring 2020, the company saw ridership plunge.
But Seastreak persevered with the newbuild plan, and the new vessel’s name was conceived as a tribute to medical workers who continued to travel by ferry to treat Covid patients, said James D. Barker, Seastreak’s director of business development and marketing.
After making the transit from New Orleans to New Jersey, the Courageous started service in mid-December 2021, running peak departures including 6 a.m. and 8 a.m. out of the Seastreak terminal at Highlands, N.J.
One important design difference with Courageous is a modi ed bow radius that allows more versatility with bow loading at different landings. That includes matching to the Steamship Authority docks at Martha’s Vineyard, Mass., a big summer destination for Seastreak customers.
Main propulsion comes from four MTU 12V4000 M64 diesel engines producing 1,873 hp at 1,800 rpm each. The mains are connected to four Kongsberg KaMeWa 5654 waterjets.
Ship’s service power is the responsibility of twin John Deere 6068 SFM85 gensets. The new ferry is USCG certi ed Subchapter K.
With a wheelhouse electronics suite by Furuno USA, the Courageous has a distinctive LED lighting system on outdoor areas of the vessel with a red, white, and blue color scheme. Imtra supplied Norsap seats, Exalto wipers, LED lighting, Libra doors, and DHR navigation lights.
Another major upgrade is the latest-technology insulated glass in the cabin windows. The glass reduces the solar load on the passenger cabin and provides fog-free views, a major problem on older boats during the frigid harbor winters.
The company had its best season ever in 2019, and with the easing of restrictions during 2021 saw commuter ridership return to almost 60% of that baseline.

MARK W BARKER
By Ken Hocke, Senior Editor
The fi rst new U.S.-fl agged Great Lakes bulk carrier built on the Great Lakes in more than 40 years.
Anew, U.S.- agged Great Lakes bulk carrier built at a Great Lakes shipyard has been delivered for the rst time in 40 years.
In 2019, the Interlake Steamship Co., awarded a contract to Fincantieri Bay Shipbuilding to build a new River-class, self-unloading bulk carrier.
It is believed to be the rst ship for U.S. Great Lakes service built on the Great Lakes since 1983. The ship will transport raw materials to support manufacturing in the Great Lakes region.
The 639'×78'×45', 28,000-dwt Mark W Barker was built at Bay Ship in Sturgeon Bay, Wis. Interlake Steamship, Middleburg Heights, Ohio, operates the largest privately held U.S.- ag eet on the Great Lakes, with nine vessels that carry bulk cargoes. Its newest vessel, until now, the Paul R. Tregurtha, was built at American Ship Building Co., Lorain, Ohio, in 1981. The 1,013'×105'×56' Paul R. Tregurtha has a capacity of 68,000 tons and is the longest vessel on the Great Lakes.
Bay Engineering Inc., Sturgeon Bay, designed the Mark W Barker bulk carrier, complete with advanced vessel and unloading systems automation.
With a draft of 29'1", the new selfunloading bulk carrier has a unique cargo hold arrangement and cargo hatch covers designed for maximum cubic space and the ability to handle dif cult cargoes. The vessel incorporates a ap rudder as well as bow and stern thrusters for high-level maneuverability.
Travis Martin, president, Bay Engineering, noted that there is “added protection from damage such as doublebottom and side-shell voids above damage stability requirements.”
The ship also has a sliding cargo bulkhead door forward and aft garages with garage-door access to cargo holds that provide storage for two Caterpillar 938M front-end loaders and two T870 Bobcat box girder systems with only a single transverse bulkhead.
The new bulk carrier is a gravity, self-unloading/mechanical unloading vessel used for hauling cargoes of salt, coal, iron ore pellets, stone, sand, and hot briquette iron (HBI). It’s design also allows for carrying unique cargo on spur deck hatch covers.
The 15,507 gt. Mark W Barker’s main propulsion comes from two 16-cylinder EMD 16ME23B Tier 4 diesel engines, producing 4,000 hp at 900 rpm each. The mains are connected to Kongsberg KaMeWa 4-bladed controllable pitch propellers built to Ice 1C standards (but not classed) through Lufkin CSQ11400-5-PTO 7.5:1 marine gears. The vessel has a running speed of 13 mph.
The Mark W Barker was fitted with two Kongsberg thrusters for added maneuverability — one bow and one stern. Kongsberg also handled the steering system and controls duties for the new bulk carrier.
Tankage includes 109,077 gals. of diesel fuel; 16,939 gals. potable water; 6,444 gals. urea; 7,504 gals. lube oil; and 19,770 gals. ef uents.
For electrical power, there’s a Caterpillar C32 ACERT marine package genset rated at 940-kW, two 2,500-kW shaft generators and one 274-kW emergency generator.

Vessel Report RIBs

The distance the RIBS operate from the Navy vessels “varies according to the mission and what they are utilizing to go after — small arms or other,” said Silver Ships David Hunt.
Hunt said the most noteworthy work at Silver Ships “is the multiyear contracts we have going with the Navy.”
There’s a ve-year contract for ve different variants of eight- and 11-meter RIBS, which will consist of either cabin and center console RIBs or a combination. Included in the mix will be support boats for Navy SEAL training. Other RIBs will go to the Coast Guard to be used as special purpose craft for law enforcement.
“Over the course of ve years there will be a couple of hundred,” said Hunt.
Another order is for 11-meter (36'×10') RIBs for the Marine Corps to be used as safety boats supporting amphibious training, which are basically “carbon copies” of boats built for the Marines in 2018. It’s a three-year package with 10 boats for 2022, 10 to 15 boats in 2023 and the remaining boats in 2024.
Hunt said the Marines chose the RIBs “because they are geared to carrying signi cant numbers of passengers,” as many as 25, making it challenging for boats to run in all conditions. They are built for carrying heavy loads because “they don’t know when they might have to rescue personnel from the water.”
Overall, Hunt doesn’t expect any real design changes for Silver Ships RIBs. “The biggest changes we see as a company is trying to keep up with changes in technology.”
An example is Silver Ships recent adaptation of Mercury Marine’s V10 350-hp Verado outboard with increased power and torque.
“We have to make some adaptions so we can start to utilize that power,” Hunt said.
WILLARD MARINE
Willard Marine Inc., Oceanside, Calif., debuted an updated version of
MetalCraft Marine
MetalCraft Marine Interceptor RIBs feature a fold-down bow and a pair of Porta Products transom brackets with 425-hp Yamaha outboards.
its seven-meter (23'9"×9') RIB, the SeaForce 777, at December’s International WorkBoat Show in New Orleans.
Two things immediately noticeable on the SeaForce 777 are its new deck design and the 300-hp Oxe diesel-powered outboard. The deck is completely ush and set up for using rail-mounted modular seats instead of single placement seats.
There will also be Humphree interceptor trim tabs “to bring it up on a plane faster than it had been in the past,” said Willard Marine’s Jordan Angle.
Willard Marine is working with two companies to improve the seven-meter RIB’s hull ef ciency.
The goal is not to maximize speed — currently the seven-meter hull has a speed limit of about 38 knots — but to help the “hull ride softer for more operator safety and comfort,” said Angle.
The focus is on hull ef ciency that will help cut fuel costs and improve operator comfort and safety. Willard Marine has learned, after providing boats to the military for the past 35 years, “that the vast majority of career boat operators end up going out on disability because of G-forces experienced on the boat,” said Angle. Thus, the introduction of the shock-mitigating seats on the seven-meter RIB and a softer riding hull “so operators don’t end up going out on disability.”
Willard Marine has used shockmitigating seats on its larger 11-meter boats and some seven-meter boats for the Army’s Special Forces.
Now the company hopes to convince the Navy to out t all of its seven-meter boats with shock-mitigating seats.
While the seats are expensive, “it’s less expensive than having to pay for people being on disability for the rest of their lives,” Angle said.
The seven-meter is out tted with a 300-hp Oxe diesel. Since the motor weighs about 1,000 lbs., the seven-meter hull is limited to a single outboard.
However, on Willard Marine’s 11-meter RIB (36'4"×11'9"), Angle hopes to mount two 300-hp Oxe diesel outboards.
