Blue Rim 5™ • Catamaran Dan • Nevado Raiders™
A Hobie Getaway catamaran with a 24-inch draft — purpose-built for reef observation, coastal science, and sustained expedition life across the Western Caribbean.
Shamrocket is not just an expedition vessel. It is GROAN Level 1 — the physical decision arm of a five-level ocean intelligence system. Every deployment is tasked by DMAP-CAL™ and the Cross-Module Interaction Engine above it. Every data point collected feeds directly into cross-ecosystem causal analysis. In the GROAN architecture, MOOP is where the intelligence system meets the ocean.
The small cat platform is built around a simple idea: use a lightweight, shallow-draft sailing catamaran as the primary vessel and pair it with a modular equipment sled carrying the essential systems needed for coastal living, travel, and exploration. The result is a system that stays close to shore, keeps passages short, reaches places larger vessels cannot, and lowers the barrier to ownership and long-term use.
A 24-inch draft opens up reef zones, sandbars, protected shallows, and remote coastal areas that deeper boats cannot safely reach. Shamrocket anchors directly over shallow reef structures that dive boats cannot approach — placing the science platform on top of sites that rarely see in-water observation.
Sail-driven movement, fewer major systems, and reduced dependence on fuel and marina infrastructure create a cleaner, more practical operating model. Fewer systems mean fewer failure points — critical for sustained multi-year operation in remote coastal environments.
Lower cost, lower complexity, and a modular support system make long-term repeat use realistic. The Rim Run™ returns to the same 100+ sites every year. That continuity is the scientific value of the platform — it builds over time.
As GROAN Level 1, Shamrocket carries a disciplined scientific payload designed for repeatable, multi-year reef observation. Every instrument feeds data directly into the GROAN data architecture. The baseline kit keeps the mission operational continuously — support and partnerships expand what can be measured without changing what the platform fundamentally is.
Apera PCO60-Z multiparameter meter (surface air temperature, subsurface temperature, pH, salinity, ORP). DIY Secchi disk for visibility. Every site, every visit, every year.
FAA-licensed UAV operations for repeat photogrammetry, bleaching documentation, seagrass and mangrove mapping, and annual visual comparison of shallow coastal habitats. Operators must be licensed. This one is.
Snorkel-based observation is the operational baseline. Reef Check EcoDiver SCUBA certification adds reef wall documentation, deeper fish community surveys, and benthic assessment at depth. Scheduled: Bocas del Toro, August 2026.
Underwater camera for standardized wide-angle, close-up, and transect-style video and photography at every site. Visual record preserved for annual comparison and independent validation. Underwater UV Imaging — capturing ultraviolet spectrum data below the surface.
GPS-enabled device for permanent site coordinates. Standardized logging format capturing all measurement parameters. Every observation is site-indexed, timestamped, and structured for long-term comparison.
Optical DO sensor is the highest-priority expansion instrument. Hypoxic events in Western Caribbean lagoons have caused mass coral mortality misattributed to temperature because DO goes unmeasured. Added when instrument support is secured.
The sled is what transforms the catamaran from a day-sailing setup into a true coastal expedition platform. Instead of forcing the catamaran to carry every heavy or bulky system onboard, the modular sled carries essential support gear while the sailing platform remains light, efficient, and capable.
The sled allows the primary sailing platform to stay simple while still supporting real coastal life. This makes the overall system practical for two adults and potentially workable for a small family within a disciplined coastal operating model.
It becomes a true coastal exploration system with room for power, gear, food, water, and the full scientific payload — without compromising the performance and simplicity that make the catamaran the right tool.
This platform is built around coastal discipline. The model depends on short sailing legs, daily landing or anchoring, early arrivals, and constant awareness of nearby shelter options. A 200-Ton Master with nuclear submarine qualification does not take unnecessary risks. The platform stays in its operational envelope.
No vessel removes risk. Seamanship, judgment, preparation, and conservative operation still matter. The point is that within a disciplined coastal envelope, a small catamaran operated by a qualified mariner is a practical and effective platform for exploration, science, and daily life.
The operator holds a USCG 200-Ton Master license, USN submarine qualification, and has been operating on the water professionally for decades. The platform is capable. The operator is qualified. The envelope is understood.
One of the biggest strengths of this model is that it lowers the barrier to entry. Many people will never own a large cruising yacht. That does not mean they should be excluded from meaningful time on the water — or from conducting real science.
Boats in this category are dramatically less expensive than full-size cruising vessels. The financial barrier to sustained coastal expedition life is not what most people assume.
Less dependence on fuel, marina infrastructure, and complex systems makes multi-year operation realistic on a practical budget. Zero carbon means zero fuel cost.
Insurance, maintenance, and logistics are far more manageable than large-boat cruising. The platform sustains itself. The science continues regardless of sponsorship.
A major advantage of this type of platform is that it does not need to cross every ocean it explores. After covering one region thoroughly, it can be disassembled, containerized, shipped, and reassembled elsewhere. Blue Rim 5™ begins in the Caribbean. It does not end there.
This opens the door to exploring many different coastlines without taking on unnecessary transoceanic passages. It saves time, lowers risk, and keeps the platform aligned with its real purpose: coastal exploration and sustained reef observation where the data is most needed.
Shamrocket can move from the Caribbean to the Indo-Pacific, the Red Sea, or any other coast without requiring an entirely different class of vessel. The same proven platform, the same scientific systems, a different region — and a growing comparative dataset that no single-deployment program can match.
People who want real coastline time, access, and freedom without the burden of a large cruising yacht. The platform is the mission, not a means to a marina.
Those willing to travel with discipline, keep passages short, and embrace practical coastal adventure. The model works for two adults and, within a disciplined operating envelope, for small families.
The 24-inch draft places a science platform on top of reef sites that research vessels cannot approach. Multi-year commitment to the same sites builds longitudinal data. GROAN Level 1 operators need a platform that stays in the water, keeps coming back, and carries the instruments.
The small cat platform is not a lesser version of large-boat cruising. For coastal access, affordability, simplicity, and repeatable reef science, it is the better tool. Paired with a modular sled system and a disciplined scientific payload, Shamrocket becomes a true coastal expedition platform capable of supporting real travel, daily life, sustained observation, and the field intelligence work that GROAN requires.
This is not about making do with less. It is about using the right platform for a 20-year commitment to the same reef systems — and building a record of what is happening to them that no one else is building.
