70-Metre Antarctic Ice-Strengthened Research Vessel — Conversion
230 ft (70 m) · North American Shipbuilding · ABS Ice-Strengthened · 1997
An ABS ice-strengthened hull built for Antarctic research service — high-latitude capability engineered from the keel up.
Serious volume for a 70-metre platform — the space to build an owner-standard expedition yacht within a proven hull.
Shipyard-built accommodation for crew, expedition staff and scientists — the framework for guest and owner suites.
Research-grade working deck and helideck capability for touch-and-go operations and expedition logistics.
A purpose-built Antarctic research vessel — the ice capability and ocean pedigree are already engineered in.
Standard capability is built into the hull today; optional systems are engineered in during conversion.
A conversion is far more than a technical upgrade. It is the transformation of a proven, ocean-tested hull into a yacht with new purpose, new value and a life of its own — and it rewards the owner who can see what others cannot.
The hull, machinery and class are proven. The conversion re-imagines everything above and around them for owner-standard global expedition service — from the tropics to the poles. In outline, the scope includes:
Design study of Project Concordia converted to an owner-standard global expedition yacht — helideck, hangar, submersible and tender handling, and owner decks above a proven ice-strengthened hull.




Conversion renderings — Grant Maughan Design. Indicative concept; final arrangement to owner specification.
The hull as she operates now — a purpose-built polar research vessel with the ice capability, deck space and ocean pedigree already engineered in.
