Odyssey of AION Patagonia → Southern Ocean Command • Autonomy • Fieldcraft

Leading an Antarctic circumnavigation in the Sixties.

More than 25 years of offshore sailing, a period in medicine, then command: building an operational capability to endure over time in a constrained environment. The goal is not performance, but continuity: maintaining an autonomous expedition sailboat in direct contact with the Southern Ocean, with real margins on safety, energy, maintenance, and the quality of observations.

Professional certificates (STCW), ocean deliveries, command in real conditions, then cold seas: the project is built as a system. Routing, fatigue management, decision thresholds, redundancies and procedures: everything aims to limit improvisation and to protect the boat on a long, exposed route where mistakes are paid for in breakage or immobilization.

Background

From offshore to command: method, margins, and operational endurance

The common thread: making navigation repeatable and “auditable” — weather decisions, margins, energy, maintenance, and safety — to sustain a long expedition while producing usable observations.

A first Atlantic crossing acted as a trigger: leaving medicine for maritime training, STCW certifications, and accelerated learning driven by field experience. Early on, the challenge became to industrialize the fundamentals: procedures, checklists, watch discipline, and the ability to decide under uncertainty.

Long-range deliveries: repeated passages (Atlantic, Pacific), taking over varied platforms, managing temporary crews, and GRIB/ECMWF-based routing. Each delivery is an exercise in controlled compromise: weather window versus fatigue, speed versus wear, comfort versus safety, with a single priority: arrive without breaking the boat.

Commanding private yachts after obtaining the Master 500 GT set the framework: full, 24/7 responsibility for safety, vessel integrity, and the program. This is where the reflexes useful in the South were forged: define thresholds, say no to a “borderline” window, wait, and walk away without regret when margins vanish.

2016–2022: intensive sailing on a Garcia Exploration 60 (aluminum, lifting-keel), focused on cold seas. Condensation, icing, accelerated aging, constant maintenance, and defending energy every day: performance becomes secondary to the ability to last.

Then came the choice of ARION (14 m Strongall aluminum): a platform designed for expedition work. Thick structure, simplified yet redundant systems, maintenance access, and reinforced energy autonomy. The goal is no longer to “go south” occasionally, but to remain there long enough for an exposed route in the Sixties, while limiting technical debt.

Odyssey of AION brings this trajectory together: depart Patagonia, commit to a clockwise arc around the continent, adapt to the field (weather, sea state, ice), and close the loop if conditions allow. Afterwards, depending on ice, logistics, and energy, a safe-harbor phase may be considered in a sheltered anchorage on the Peninsula, with a restart the following summer.

Method

Operational architecture: redundancy, simplicity, decision-making

Design principles

  • Useful redundancy on vital functions: energy, navigation, communication, water, safety.
  • Maintainable simplicity: prioritize systems that can truly be repaired offshore (tools, spares, access).
  • Anticipation: ECMWF/GRIB weather, ice watch (imagery + observation), fallback scenarios, permanent Plan B.
  • Procedures: checklists, routines, decision thresholds defined in advance to avoid improvisation under pressure.

Specificity: sailing in the Sixties

  • Short weather windows, rare fallbacks: decide early, accept waiting, limit exposure.
  • Drifting ice / mobile pack: combine satellite with the field, adjust strategy continuously.
  • Long legs without true shelter: manage fatigue, protect energy, avoid technical debt.
  • Constant objective: continuity + margins rather than a “record.”
Skills

Bluewater autonomy geared to the Southern Ocean

Weather routing

GRIB/ECMWF reading, synoptic analysis, thresholds, continuity-versus-wear tradeoffs.

Cold-region navigation

Ice (brash/pack), drift, exposed anchorages, realistic margins, active caution.

Energy & autonomy

Budgets, priorities, solar / hydro-generator / wind mix, operational frugality.

Safety with a small crew

Watch organization, fatigue, MOB/EPIRB procedures, disciplined decision-making.

Maintenance

Offshore diagnosis and repair, prevention, system access, critical spares management.

Multi-season expedition

Planning, logistics, safety, and integrating data/storytelling without disrupting operations.

Science

Long presence, simple measurements, solid metadata

A committed circumnavigation keeps a sailboat in under-sampled areas for a long time. The chosen approach is pragmatic: continuous measurements that are properly contextualized (position, time, conditions, protocol).

Protocols and time-series structuring are developed with marine biologist Sarah Rosenthal, so data remain usable beyond storytelling: consistency, traceability, and metadata.

Visual narrative

The Odyssey of AION documentary film

The film follows the expedition as it is actually run: preparation, technical constraints, weather decisions, and the route in the Sixties. The aim is to show operational reality: energy, maintenance, fatigue, sea and cold — without staging.

Collaborate / support

For technical, scientific, or media partners, Odyssey of AION is a rare opportunity: associating a name with a truly committed expedition, documented and measurable. Priorities: reliability, safety, and the value of produced data/images.
