The following is text of a news release from Metal Shark:
(JEANERETTE, La.) — Metal Shark is building a welded aluminum 55-by-17-foot pilot boat for the Pascagoula Bar Pilots Association in Mississippi.
Designed in-house, the new 55 Defiant represents the latest evolution in Metal Shark’s pilot boat lineup. The vessel incorporates the “faceted hull” design initially developed by Metal Shark for the U.S. Navy 40 PB program, and features an enhanced version of Metal Shark’s “pillarless glass” in a two-tiered, reverse-raked arrangement.
Metal Shark initially implemented automotive-style frameless glass into its pilothouse designs to eliminate the dangerous blind spots common on legacy pilothouse designs fitted with smaller, framed windows. As a further evolution of this concept, the new 55 Defiant’s pilothouse features a second tier of glass, improving downward-angle visibility during man-overboard retrieval, or while operating alongside another vessel. Large overhead spotter windows provide unimpeded upward visibility during pilot transfers.
While its Defiant-class vessels are popular among a wide range of operators, Metal Shark has developed a deck arrangement optimized specifically for pilots. Flat, non-skid decks run from bow to stern and allow pilots to move quickly and safely around the vessel. Safety rails and grab handles are strategically placed, and pilot boarding platforms are configured to suit the requirements of each operator.
For Pascagoula, the 55 Defiant has been equipped with a foredeck transfer zone with integrated stairways, allowing port, starboard, or forward access to two deployable platforms with integrated safety rails allowing pilots to board ships from either side of the vessel.
The 55 Defiant’s climate-controlled cabin is equipped with four Dometic HVAC units and features eight Llebroc seats, accommodating a single operator plus seven pilot passengers. For comfort and convenience, each swivel seating position is equipped with a footrest, adjustable armrests, white/red LED lighting, a drink holder, and two 12-volt USB outlets.
A full electronics suite includes Furuno's TZtouch2 multifunction display system with integrated GPS, radar, depth sounder, and a FLIR M Series 364C premium thermal imaging system for nighttime operations. Five closed-circuit cameras allow the vessel’s operator to monitor the engine room and aft deck from multiple angles at a glance while still maintaining watch.
Accommodations below include an enclosed head compartment with freshwater sink, bunks, and individual storage lockers for crewmembers’ personal items. Acoustic insulation and flooring are employed throughout the vessel to reduce noise and vibration.
To meet the performance requirements of the operator, the new vessel will be powered by twin Caterpillar C18 engines rated at 803 horsepower each, turning Michigan Wheel 34-inch-diameter Nibral four-blade propellers through Twin Disc MGX5146A 1.961 gears. This combination will deliver an expected cruise speed in the 25-knot range and a top speed approaching 30 knots. An 800-gallon fuel capacity allows for a cruise speed range of approximately 280 nautical miles.
“Metal Shark continues to develop next-generation pilot boat designs custom-tailored to meet the requirements of individual pilot groups, each based upon an extensively proven hull form,” said Carl Wegener, Metal Shark’s vice president of commercial sales. “We’re excited to be building this new pilot boat for Pascagoula, which is their second Metal Shark pilot boat and the first in a series of this new 55-foot Defiant platform.”
The new vessel is scheduled to deliver this year. It follows two 45-foot Defiant pilot boats delivered to Belle Chasse Marine Transportation last year, and 45-foot and 64-foot Defiant pilot boats delivered in 2018.
