Catamaran Dan's Nevado Raiders™ & Blue Rim 5™

Blue Rim 5™ Global Sailing Expedition

Blue Rim 5™

Blue Rim 5™ is a long-range, multi-year global sailing expedition tracing the blue edge of the planet—coastlines, islands, harbors, and river mouths reachable under sail. It moves one leg at a time with a mixed fleet of small expedition sailboats and larger guardian vessels, following a simple rule: we go where it makes sense, when it makes sense—and stop or reroute when it doesn’t.

This expedition is not a race. No leg is intended to be hurried. Progress is measured in seamanship, understanding, and human connection—not miles per day.

Blue Rim 5™ is not a cruise, not a yacht club, and not a packaged tour. Crews join for the legs that fit their lives and operate as independent vessels with shared purpose. Each captain/vessel/crew covers their own expenses (food, fuel, maintenance, fees, local activities, and personal costs). Only expenses explicitly incurred by the fleet as a whole—and agreed to in advance— are shared and divided evenly among participating vessels.

Kids and families are central to the mission—putting young people on real shorelines so they can see, first-hand, how a dangerously warming world is already reshaping life along the waterline.

The model is built for the century we actually live in: start small, learn fast, build the fleet, and keep going as long as the risks are acceptable. We will not trace the planet’s rim and lie to children about what’s happening to it.

Leadership & Seamanship

Blue Rim 5™ is led by Catamaran Dan, an experienced mariner whose background combines formal qualification, instruction, military discipline, and decades of real-world adventure sailing.

This combination shapes the culture of Blue Rim 5™: calm decision-making, conservative risk management, and preparation over bravado— knowing when to go, when to wait, and when to say no.

Expedition overview • first chapters

Blue Rim 5™ — First Chapters

The opening chapters of Blue Rim 5™ are designed to unfold over multiple years, moving deliberately along coastlines rather than racing between destinations. The focus is on learning regions deeply, building seamanship through repetition, spending real time in the water, and forming lasting connections with local communities.

Rather than fixed dates, the expedition is organized around flexible time blocks, allowing weather, safety, and opportunity to guide progress.

Blue Rim 5™ — Life Ashore & Passage Philosophy

When the Blue Rim 5™ fleet makes landfall, we don’t rush and we don’t consume. We slow down. We swim, snorkel, and spend time in the water that brought us there—learning reefs, currents, and shorelines the way sailors always have.

We go ashore deliberately, meeting the people who live along these coasts not as spectators, but as guests. We share meals when invited, trade stories, and—when the moment is right—music. We hike inland, visit local “must-see” places that carry real meaning, and take the time to understand how a place works beyond its anchorages.

One crew member always remains with the vessels, maintaining watch and respect for both boat and community.

The Blue Rim 5™ fleet favors daylight navigation and conservative passage planning. We do not sail at night unless conditions, safety, or geography require it to reach the next destination. Clear landfalls, rested crews, and good judgment matter more than speed or schedules.

Daylight. Deliberation. Discipline.

These stops—and the way we move between them—aren’t boxes to check. They’re how the expedition stays human. Every coast has its own rhythm, and the Blue Rim 5™ fleet listens long enough to hear it before moving on.

This overview reflects intent, not obligation. Routes adapt. Timing remains flexible. No leg is hurried.

Core mission

Cultural Exchange

Every coastline belongs first to the people who live there. We arrive as guests—not as conquerors, consumers, or spectators. Nevado Raiders™ move slowly enough to listen, learn, and earn trust. We respect local rules, local waters, and local knowledge that has kept families alive on these shores for generations.

When it makes sense, we spend money locally, hire local guides, and support the people who call these places home. Cultural exchange isn’t a slogan—it’s behavior: humility, curiosity, and respect in the real world.

We sit at real tables. We share meals. We learn names and stories. And when there’s music, we don’t just record it—we join it. We trade songs, jam with local musicians, and record sessions together when invited. Those moments—shared rhythms and shared laughter— carry the truth of a place in a way no postcard ever can.

Peace, human connection, and shared responsibility aren’t side benefits of the expedition—they’re the point. If we can’t move through a place with respect, we don’t belong there.

The Viking Way — old values, modern raids

Viking Spirit

The Vikings weren’t just raiders. They were farmers, traders, artisans, and families who lived boldly—crossing cold seas in shallow-draft boats, navigating without charts, and building community wherever their keels touched shore. In Norse times, “Viking” was used as a verb—not a noun. To go viking meant to set out—explore, trade, test skill, take risk, and return changed. Nevado Raiders™ carries that same spirit forward: each raid is about the crews, the skills we test together, and the stories we bring home.

Ove Ironhand: Modern Y-DNA work traces Catamaran Dan’s paternal line through Norse seafarers of the 10th century—through Thorvald Asvaldsson, Erik the Red, and Leif Erikson—into the I1 haplogroup common among Scandinavia’s working seafarers. Signing as Ove Ironhand honors that legacy. Our “sagas” will be logbooks, film, and the wakes we leave behind.

Panama

Escudo de Veraguas

Escudo de Veraguas feels like snorkeling inside a living aquarium that the world forgot. The water is impossibly clear — that glassy Caribbean turquoise where coral heads glow beneath you and every movement sends shafts of sunlight dancing across the sand. Drop over the side and within minutes you’re drifting above layered reef systems alive with color, movement, and texture.

The coral structure here isn’t flat — it rises and folds, creating swim-throughs, pockets, and dramatic edges where reef meets deep blue. Parrotfish crunch loudly in the background. Angelfish flash neon against coral fans. Schools move as one, then dissolve into the reef like smoke. The visibility can stretch so far you feel suspended in open air rather than water.

What makes Escudo extraordinary isn’t just the marine life — it’s the isolation. No crowded mooring fields. No parade of tour boats. Just anchor down, fins on, and long, unhurried passes across reef systems that reward patience. You don’t rush here. You explore. And when you climb back aboard, salt on your skin and lungs full of clean air, you know you’ve touched something rare.

Costa Rica

Cahuita Reef

When clarity opens, Cahuita Reef glows. Natural swim corridors guide you forward, warm Caribbean water holds steady against your skin, and the reef feels calm and alive beneath your fins. This is not a chaotic outer wall — it is a measured, accessible reef system that rewards patience.

The coral formations rise in layered shelves and gentle ridgelines, creating protected channels that make long, steady snorkel passes effortless. Sunlight filters through in ribbons, illuminating brain coral, staghorn clusters, and patches of white sand that reflect light upward like stage lamps beneath the surface.

Reef fish gather here in comfortable density — parrotfish grazing, sergeant majors hovering in tight formation, angelfish flashing electric blue and yellow against darker coral. The water often feels still, even when subtle current moves past the reef face, giving the entire system a tranquil, suspended quality.

Because the reef runs parallel to shore, it invites repetition. Swim one corridor. Rest. Enter another. Each pass reveals a slightly different texture, a new pocket of activity, a subtle shift in depth. The experience is immersive without being overwhelming.

Cahuita isn’t dramatic in the way deep drop-offs are dramatic. It’s steady. Balanced. Rhythmic. A reef that lets you settle into your breathing and stay there — where time softens, distance disappears, and snorkeling becomes something closer to meditation than recreation.

Nicaragua

Little Corn Island

Endurance-friendly immersion water. Little Corn Island invites you into a smooth, steady breathing rhythm almost immediately. The reef stays present and textured beneath you, and time begins to dissolve as fish flicker through coral architecture in soft Caribbean light.

The reef system here spreads outward in gentle shelves and sandy flats, making it ideal for long, continuous snorkel passes. Visibility often stretches far enough that you feel suspended in open space rather than water. Rays cruise low over the sand. Schools shift direction in synchronized turns. The entire environment feels balanced and unhurried.

Coral formations rise in scattered clusters rather than towering walls, creating open swim lanes between them. You don’t rush this reef — you settle into it. One formation gives way to another. Subtle depth changes reveal new textures. The reef unfolds gradually instead of overwhelming you.

What makes Little Corn distinctive is its combination of clarity and calm. Even when light current moves through, it feels supportive rather than demanding. The water temperature stays consistent, allowing extended time in without tension. This is a place built for immersion, not quick passes.

By the time you climb back aboard, you feel reset. Muscles loose. Breathing slow. Mind clear. Little Corn doesn’t shock the senses — it steadies them. A reef that rewards endurance, presence, and the quiet discipline of staying in the water longer than you planned.

Honduras

Roatán

Big reef structure and deep relief define Roatán. You hover near walls where the blue darkens quickly, drift along living edges, and feel the full scale of the Mesoamerican Barrier Reef unfolding beneath you. The sense of vertical drop and expansive coral architecture immediately sets this reef apart.

Massive coral formations rise like underwater cliffs, carved with ledges and pockets where fish gather in layered depth. Light fades gradually as you peer over the edge, and the reef transitions from textured shallows into open cobalt. The contrast between reef face and deep water creates a constant sense of movement and dimension.

Parrotfish grind along coral ridges. Creole wrasse sweep through in coordinated waves. Larger silhouettes appear and vanish in the deeper blue beyond the wall. Even in calm conditions, there is an energy here — a subtle pull toward the reef edge where structure meets open water.

Swim the crest and you find vibrant coral gardens bursting with color. Ease toward the slope and the reef reveals dramatic contours, swim-through cutouts, and sudden drop-offs that remind you how alive and complex this system truly is. It’s a reef built for exploration, not repetition.

Roatán doesn’t feel delicate — it feels powerful. Expansive. Layered. A place where snorkeling becomes three-dimensional and immersive, where scale matters and the reef stretches in every direction. You don’t just float here. You experience depth, structure, and the raw architecture of one of the largest reef systems in the hemisphere.

Honduras

Guanaja — Bay Islands

Quiet, clean immersion defines Guanaja. Morning light cuts deep into impossibly clear water, coral throws crisp shadows across pale sand, and your only soundtrack is your breathing and the soft hiss of fins moving through glassy blue.

The reef systems here feel untouched and spacious. Coral heads rise in balanced formations, separated by open swim lanes that allow long, unbroken passes. Visibility often stretches far enough that the reef appears suspended beneath you, textured and precise.

Schools move calmly rather than frantically. Angelfish drift between coral towers. Larger silhouettes cruise the outer edge where the reef meets deeper water. Even subtle current feels organized — supporting forward movement rather than resisting it.

What makes Guanaja special is its restraint. It doesn’t overwhelm with dramatic drop-offs or chaotic structure. Instead, it offers clarity, symmetry, and calm. A reef that encourages presence rather than adrenaline.

By the time you climb back aboard, your breathing has slowed and your thoughts have quieted. Guanaja is immersion without noise — steady, refined, and beautifully composed. A place where snorkeling feels less like activity and more like alignment.

Belize

South Water Caye

Classic barrier reef immersion. South Water Caye sits along one of the most celebrated sections of the Belize Barrier Reef, where spur-and-groove formations carve the seafloor into natural swim lanes. When the water settles into its calm windows, visibility stretches wide and steady, and you drift above living structure that feels both powerful and perfectly ordered.

The reef rises in alternating ridges and sandy channels, guiding you forward without effort. Coral heads stack in layered relief, sea fans pulse gently in passing current, and schools of blue tang and creole wrasse move like synchronized ribbons across the reef face. Light pours down clean and vertical, sharpening every edge.

Green sea turtles graze in turtle grass beds just off the reef crest. Barracuda hover motionless in the blue beyond the drop. Nurse sharks rest beneath ledges cut deep into coral architecture. The ecosystem here feels complete — predator, grazer, coral, and current all moving in quiet balance.

Because of the spur-and-groove terrain, long drifts become effortless. You settle into rhythm. Breathe. Glide. Watch the reef unfold beneath you in repeating patterns of color and texture. It’s expansive without being overwhelming — structured without feeling rigid.

South Water Caye delivers scale without chaos. Anchor close. Fins on. Slide in. And for as long as you choose to remain suspended there, the reef carries you forward in calm, steady immersion along one of the great barrier systems of the Caribbean.

Belize

Glover’s Reef

Atoll-lagoon snorkeling that rewards time in the water. Glover’s Reef opens wide beneath you — coral heads rising like scattered islands, pale sand flats glowing in turquoise light, and visibility that stretches far enough to make every movement feel suspended in open air.

The lagoon terrain shifts constantly. Patch reef gives way to sand channels, then rises again into coral ridges textured with sea fans and sponges. Rays glide silently across the bottom. Small reef fish scatter and regroup. The water carries that calm, glass-clear quality that invites long, steady passes.

Because it’s an atoll system, the scale feels expansive. You’re not confined to a narrow reef edge — you move across open blue pockets, then back into dense coral structure. Each swim becomes a route. Each route becomes a quiet exploration of structure, light, and depth.

Marine life density builds gradually. Snapper schools hover in the distance. Nurse sharks rest in sand depressions. Occasional larger shapes cruise the perimeter. The rhythm here favors endurance — slow, deliberate swims that let the environment reveal itself layer by layer.

What makes Glover’s special isn’t just biodiversity — it’s immersion. You drop in and stay in. Long-distance swim days stack up fast because the terrain keeps unfolding ahead of you. It’s expansive, steady, and deeply rewarding — the kind of place where time in the water feels earned.

Belize

Turneffe Atoll

Massive footprint and constant variety define Turneffe Atoll. One session is glassy and calm inside the lagoon, the next feels deeper and more dramatic along the outer edge — an atoll that stays fresh day after day because the terrain keeps changing under your fins.

Inside, the water can turn mirror-smooth, with coral heads rising like small cities beneath you. Sand channels open into swim lanes that make long, steady passes effortless. Light pours down clean, and the reef reads clearly — structure, shadow, and movement all in high definition.

Move toward the edges and the mood shifts. The blue deepens fast. Coral faces grow steeper. Schools appear in layers, then dissolve into open water. The atoll’s scale becomes obvious — you’re not snorkeling one reef, you’re crossing a whole system.

Variety is the reward here. One hour is calm cruising over coral gardens; the next is drifting a line where the reef drops away and the ocean feels present just beyond the structure. Even when you return to the same area, conditions and angle of light make it feel new.

Turneffe is a place where repetition doesn’t get stale — it gets refined. You learn the terrain, read the water, pick better lines, and stack up immersion days that feel like a progression. Calm lagoon clarity, deeper edges, constant motion — a full atoll experience in one stop.

Belize

Lighthouse Reef Atoll

Summit immersion defines Lighthouse Reef Atoll. The blue turns electric, visibility stretches wide, and the reef edge drops away into depth just beyond your fins. You hover on that boundary and feel weightless — pure Caribbean clarity meeting open ocean.

Along the rim, coral formations stack and rise in sculpted layers. Sea fans flex in steady current, sponges glow gold against cobalt water, and the terrain shifts from textured reef top to dramatic outer wall in a few fin strokes. It’s clean, sharp, high-definition immersion.

When conditions settle, the water becomes almost glassy. You drift slow lines over coral heads that stand alone like monuments, then glance outward and see nothing but deep blue falling away. The contrast is what makes this place — structure and void side by side.

Fish life gathers along the edges. Creole wrasse stream in ribbons. Larger shapes cruise the drop. Light penetrates deep enough that even the wall face reveals detail — ledges, pockets, vertical relief that reminds you this atoll rises from serious depth.

Lighthouse isn’t casual snorkeling — it’s exposure to scale. Electric color, sharp relief, open water presence, and clarity that feels almost exaggerated. You don’t just swim here — you suspend yourself between reef and abyss and let the blue do the rest.

Origin story

Rim Lightning (1984)

This photograph was taken while crossing the equator in 1984. Mid-ocean, the line itself barely announces its presence—but the weather often does. That day, conditions shifted fast: blue sky giving way to stacked clouds, pressure building, wind sharpening, lightning striking the water ahead. For a time, the sea demanded full attention—trim right, stay disciplined, let preparation do the work.

Then it passed. What remained was a moment every sailor remembers: storm energy still in the water, air clearing, light returning around the edges. Blue below. Dark above. Salt, sky, and motion layered together. That exact moment became the inspiration for Rim Runner™.

Rim Lightning set the standard that followed: preparation over bravado, competence over comfort, and calm execution when conditions change. Not to celebrate danger—only to honor readiness and respect for the sea. The storm passed. The lesson stayed.
