Assembly

Hull joining, bulkhead bonding, and structural integration

Systems

Electrical, plumbing, HVAC, and propulsion installation

Joinery

Interior cabinetry, furniture, and finish carpentry in cherry wood

Paint

Fairing, priming, topcoat application, and antifouling

Rigging

Mast stepping, standing rigging, running rigging, and deck hardware

Sea Trials

Engine commissioning, sail testing, systems verification, and performance checks

Delivery

Final inspection, documentation, owner orientation, and handover

Our People Are Our Greatest Asset

40 Grados Sur employs 45 to 50 people. Our team includes laminators, carpenters, electricians, mechanics, painters, riggers, and quality control specialists.

Many of our core craftsmen have been with us for 14 or more years — they joined when production started in Argentina and have built every generation of the Antares 44. This continuity of experience is rare in boat building and directly translates to consistent quality.

Our team knows our boats intimately. They understand the tolerances, the sequences, the details. That institutional knowledge cannot be replicated — it is earned through thousands of hours of hands-on work across dozens of hulls.
