From the Panama isthmus to the Sea of Cortez — down the Pacific coast of Central and South America through entirely different ocean systems, reef types, and ecosystems that the Caribbean circuit can never reach. The second chapter. The longer story.

The Crossing
Panama. The Isthmus Crossing.
Rim Run Caribe™ ends in Panama. Rim Run Pac™ begins there. The isthmus crossing — Shamrocket and trailer hauled overland from the Caribbean side to the Pacific coast — is the physical hinge between the two circuits. Two oceans. One boat. One operator.
The Panama Pensionado residency program anchors the logistics. Pensionado status provides import duty exemption on the truck and trailer — a meaningful cost reduction that makes overland transport and extended Panama operations financially viable. Panama becomes the operational base for the Pacific launch.
Why the Pacific
A Different Ocean Entirely.
The Pacific is not an extension of the Caribbean. It is a fundamentally different oceanographic system — upwelling-driven, thermally dynamic, with reef systems and marine biodiversity that bear almost no resemblance to the Mesoamerican barrier reef.
The Humboldt Current off Peru and Chile. The Sea of Cortez — one of the most biodiverse marine environments on earth. Eastern Pacific coral systems under entirely different thermal stress profiles. For GROAN™, the Pacific circuit isn't more of the same data — it's a completely new dataset.
The Circuit — Development Phase
Panama South to Chile. Then North to the Sea of Cortez.
The Pac circuit runs south from Panama along the Pacific coast of Central and South America — Colombia's Pacific coast, Ecuador's coastal arc, Peru, and Chile — before the return leg north through Central America to Mexico's Sea of Cortez. Shamrocket operates as a coastal platform throughout: no extended offshore crossings on the primary circuit. Route details are being refined as Caribe launches and operational experience accumulates.
Circuit Status
Rim Run Pac™ is in active route development following completion of the Rim Run Caribe™ circuit architecture. Country-level detail, days-at-anchor estimates, and stop-by-stop science priorities will be published as the Pacific circuit is built out.

The Galápagos Islands (~600 miles offshore Ecuador) and Cocos Island (~340 miles offshore Costa Rica) are among the most significant marine ecosystems on earth — and both are beyond Shamrocket's primary coastal operational envelope. These sites are flagged for future extended-range operations if a support vessel or larger platform becomes part of the expedition infrastructure. They are not removed from the long-term vision. They are simply honest about what a 17-foot catamaran does safely.

When Rim Run Caribe™ completes its first full circuit, the GROAN™ database will hold a baseline reef health record across 11 Caribbean countries. When Rim Run Pac™ adds its Pacific layer, something more significant becomes possible: genuine cross-ocean comparison under the same methodology, the same operator, the same platform.
No institution currently holds that dataset. Not because it isn't valuable — because it has never been operationally feasible to collect. A 17-foot catamaran with 24 inches of draft, powered by wind and solar, operated by a single USCG-licensed master captain with nuclear submarine training, running both circuits back to back — is precisely the platform that makes it feasible.
🌊
Sea of Cortez
One of the most biodiverse marine environments on the planet. Dramatically different thermal profile from the Caribbean. Northern Pacific terminus for the circuit.
🐋
Ecuador Coastal Arc
Cold Humboldt and warm Panama Current convergence along the mainland coast. Machalilla NP — Ecuador's premier marine protected area. Species assemblages found nowhere else on the coastal Pacific.
🌡️
Humboldt Current
One of the most productive ocean systems on earth. Cold-water coral analogs off Peru. Entirely different chemistry profile from anything collected in the Caribbean.
🌿
Osa Peninsula
Costa Rica's Pacific jewel — Corcovado National Park borders one of the most biodiverse coastal zones on earth. Pacific jungle meets reef in a system almost completely distinct from the Caribbean side.
