Atlantic Wind Transfers (AWT) announced that it has ordered six Chartwell
Ambitious-class crew transfer vessels (CTVs) for offshore wind unit servicing. They will be
built by St. John’s Ship Building Inc. at its shipyard in Palatka, Florida.

The first two are expected to be delivered in summer 2023 and January 2024 respectively,
with four further builds in the pipeline. The vessels will comply with the U.S. Environmental
Protection Agency’s Tier 4 regulations, among the world’s most stringent emissions rules for
marine engines. The Ambitious class CTV design is a 25.2 meter aluminum catamaran with
the capacity to transport 24 personnel to and from turbines with speed, safety, and stability.

Orders for the Ambitious class design are now well into double-figures, with boats currently operating in
Scotland, France, and Virginia. This simply confirms AWT’s continued partnership with
Chartwell Marine, and demonstrates its commitment to the growth of the U.S offshore wind

These CTVs will be certified under the United States Coast Guard Subchapter L regulations,
and will be able to operate on any wind farm in the United States under Safety and Inspection
standards of the U.S. Coast Guard.

AWT currently operates the only two crew transfer vessels in the U.S. under long-term
contracts servicing the Block Island Wind Farm and Coastal Virginia Offshore Wind Farm.
