CONSTRUCTION ACTIVITY AT WORKBOAT YARDS Austal USA delivers Navy’s latest unmanned surface vessel

Austal USA, Mobile, Ala., has completed construction of the 338'×93'6" expeditionary fast transport ship Apalachicola (EPF 13) for the Navy.

The first EPF, formerly known as joint high-speed vessels, was delivered in 2012.

The EPF’s large, open mission deck and large habitability spaces enable the ship to conduct a wide range of missions. With its ability to access austere and degraded ports with minimal external assistance, EPFs provide options to fleet and combatant commanders.

With 13' drafts, the catamaran vessels have performed humanitarian assistance, disaster relief, maritime security, surveillance, command and control, counter narcotics, and additional operations around the world.

Austal USA has been 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.

“EPF 13 is derived from Austal USA’s mature Spearhead-class EPF high-speed, flexible, 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 required modifications 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.”

Main propulsion comes from four MTU 20V8000 diesel engines hooked up to four Wärtsilä steerable, reversing waterjets. The propulsion system gives 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.

The ship has a range of 1,200 nautical miles at 33 knots with a full load, 4,700 nautical miles at 21 knots with no cargo, and 2,000 nautical miles at 21 knots with a medical full cargo. The ship has a crew capacity of 36.

Snow completes 64’ boat for Savannah Pilots

Earlier this year, Seattle-based Snow & Co., delivered the Savannah, an aluminum 64'×19'6"×3.63' pilot boat, to the Savannah Pilots Association, Savannah, Ga.

A second 64-footer for the Savannah Pilots will be delivered by the end of 2022. A third pilot boat for the San Francisco Bar Pilots is also under construction, said Tim Kolb, vice president of business development at Snow & Co. “Pilot boats are part of a product line Snow & Co. will be going after in the future,” he said.

The Savannah Pilots two flush-decked pilot boats were designed by Camarc Design, Dunoon, Scotland, and are built to the same basic design. (The pilot boat for San Francisco was also designed by Carmarc.)

The two pilot boats feature a singlechine, deep-V hull “that’s really proven itself for seakeeping and maneuvering next to ships,” said Rich Galuk. chief engineer and captain with the Savannah Pilots. “You’ve got to be able to run in any weather.”

A run for the pilots to meet incoming vessels starts from the pilots’ station, located at the head of the Savannah River about 25 miles from the port of Savannah, and goes out into the open ocean for about 15 miles. It’s a run the pilots make up to 3,500 times a year.

The Savannah’s maximum speed is about 35 knots with a pair of 1,700-hp MTU 12V2000M86 diesels driving HamiltonJet HTX 52 waterjets through

ZF 3055 gears. “We upgraded to the HTX 52 series for better performance,” said Galuk. The driveline was also upgraded to a Geislinger, which allows “vibration frequencies to be tuned out of the driveline.”

In the wheelhouse are six Beurteaux pilot seats and three Stidd shock mitigation seats, two for the crew and one for a pilot. A simple galley consists of a refrigerator and a microwave. In front of the wheelhouse is the boarding platform. Aft of the wheelhouse, on the starboard side, is a 500-lb. capacity rescue davit. — Michael Crowley

Fishing Charters. The boat, designed by Brix, has a draft of 2'4".

“Since the Conception re, we worked really close with the Coast Guard to make sure everything was up to the new standards,” said Capt. Charlie Crane, Brix Marine’s sales and marketing director.

The new Coast Guard standards, issued in response to the re and loss of life on the 75' dive boat Conception off the coast of California in 2019, require additional re safety requirements for small passenger vessels, including re detection and suppression systems, avenues of escape, egress drills, crew re ghting training, watchmen monitoring devices, and the handling of ammable items such as rechargeable batteries.

Booth 2938

Double Down features a walk-around cabin, three sliding doors, insulated sh holds, diamond plate decks, downrigger pads, sh cleaning stations, and 52 welded aluminum rod holders. There are also eight private berths with personal storage, two queen berths in the pilothouse, hydronic heating system, galley with full-sized fridge, oven and microwave, head with shower, seating for 12 in the main cabin, aft deck bench seating, bow lounge seating, and Kryptek vinyl wrap.

The electronics suite includes twin Garmin 16" MFDs, PS60 panoptix through-hull transducer, airmar 509LHW through-hull transducer, GSD26 sounder module, GT 30THP clear-view/side-view transducer, NEMA 2000 networking, 215 AIS, six-foot open array radar, GXM 53 satellite weather receiver, and Fusion series stereo and four-channel ampli er.

Ship’s service power comes from a 6-kW Northern Lights genset.

Main propulsion is the responsibility of four Yamaha outboard engines, producing 425 hp at 6,000 rpm each. Yamaha’s Helm Master system dictates controls with joystick steering and setpoint functionality. Double Down has a cruising speed of 35 knots.

Tankage includes 800 gals. of gasoline, 50 gals. diesel, and 55 gals fresh water.

The vessel has a 216-sq.-ft. rear cargo deck, and accommodations for three crew and 18 passengers.

The Blue Ocean RBB 700 OB will work off the coast of Hawaii for crew transport and dive support operations in deepwater. The boat is the first Tideman workboat built in North America, O’Sullivan said.

The 100% high-density polyethylene hull is sustainable, virtually indestructible, needs no bottom paint and is resistant to marine growth, according to Tideman Boats US. The new boat will be part of Blue Ocean’s fleet that includes retired Navy landing craft and other vessels.

The boat is powered by a single 150hp Mercury outboard that gives the boat a running speed of 35 knots. Blue Ocean RBB 700 OB is fitted with a Seastar hydraulic steering system.

“What was particularly special about this project was how well it was executed, considering the number of firsts,” said Silverback Marine’s Ian Gracey. “As the first Tideman HDPE vessel built in the USA, the client also had a demanding list of special requirements, including dive access, storage, and a bold, aggressive aluminum superstructure to complement the Euro-inspired lines Tideman hulls are known for.”

The electronics suite includes a Shakespeare VHF antenna, Raymarine Axiom 7" DV with transom multifunction transducer, and Hella Seahawk lighting.

“We expect these HDPE hulls to dramatically impact the industry,” said Gracey. “The durability is an unmatched combination that with the design, performance, and the A-team at Tideman US behind it, it’s going to change the way we think of workboats between 20 feet and 50 feet in nearly all sectors of commercial maritime.”

The boat, which carries a 50-gal. fuel tank, was built to handle a two-person crew and up to eight passengers. — K. Hocke

Conrad delivers hopper dredge to North Carolina

dredge built at Conrad Shipyard, Morgan City, La. The dredge was delivered in August to North Carolina’s Outer Banks. Wanchese, N.C., will be the dredge’s homeport.

Construction on the dredge began in March 2021. Jensen Naval Architects and Marine Engineers, Seattle, (a subsidiary of Crowley) 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 significant 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 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 Miss Katie.

“The Miss Katie has been specifically 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 configuration will allow spoil discharge in shallow waters, thus preventing the vessel from grounding on her own hopper load.”

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.

Roudebush Yacht & Engine completes canal boat for Georgetown

Roudebush Yacht & Engine Works, Dundalk, Md., delivered a new 80'×12'×5'6", 75-passenger fiberglass/composite canal boat to Georgetown Heritage, a group tasked with restoring and revitalizing the historic Chesapeake and Ohio Canal (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 work mules. Its propulsion package contains two electric Torqeedo 10 FP motors, sparking 5.6 kW of propulsive power at 1,400 (max) rpm. The mains are connected to Torqeedo 1937-00, 12.6"×11" 5-bladed propellers. The package gives the boat a running speed of 3 knots. Six Torqeedo 48-5000 batteries provide service power.

“The intent of the design is to provide as close a replica to a 19th century canal workboat, including mule-powered propulsion with electric motor backup,” said Christopher Addington, Tridentis’ program manager for the project. “The overall goal is to update from the original 19th century design in order to reduce maintenance and comply with current regulations.”

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,” said Addington. “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
