🎥 San Diego Argonauts Featured on Hafu Go’s 20-Million-Subscriber YouTube Channel

From DF95 sailboats and scale warships to submarines and a one-of-a-kind hovercraft, our pond took center stage for a worldwide audience

About six weeks ago, popular YouTube creator Hafu Go and his production team visited the San Diego Model Yacht Pond to film a video featuring some of the most unusual and impressive radio-controlled boats they could find.

The finished video has now been released—and it attracted more than 1 million views in its first 48 hours.

With approximately 20 million YouTube subscribers, Hafu Go has built a huge global audience through fast-paced videos exploring extraordinary vehicles, machines and experiences. His latest production compares RC boats ranging from a homemade $1 steam-powered “pop-pop” boat to an extremely powerful custom RC speedboat valued at approximately $10,000.

Along the way, several San Diego Argonauts members—and a wonderfully diverse collection of vessels—received their moment in the spotlight.

From the Slowest “Pop-Pop” to a 130-MPH Speed Demon

The video showcases an astonishing range of RC boats, beginning with a homemade $1 “pop-pop” boat powered by a tiny candle and steam—possibly the slowest and simplest vessel ever launched at our pond. From there, Hafu tests fishing boats, self-righting speedboats, hydrofoils, hovercraft, sailboats, submarines and museum-quality scale ships. At the opposite extreme is a highly customized, approximately $10,000 speed demon capable of exceeding 130 miles per hour. Seeing such radically different vessels together—from a gently puttering tin boat to a carbon-reinforced rocket skimming across the water—beautifully captures the extraordinary variety found within the world of radio-controlled boating.

Hafu Learns to Sail a DragonFlite 95

One of the highlights begins when Hafu is introduced to the DragonFlite 95, or DF95, one of the most popular radio-controlled racing sailboats in the world.

San Diego Argonauts members Jon Rogers & Kerim Baran gives Hafu a quick introduction to the controls and explains some basic sailing concepts—including tacking, jibing, sail trim and how to recover when a sailboat gets caught “in irons.”

Hafu then takes control of Kerim’s bright-green DF95 and races against longtime sailor and fellow Argonaut Jon Rogers, who tells him he has been sailing for 49 years.

With Kerim coaching from the shore, Hafu learns remarkably quickly. Jon even introduces him to a little sailboat-racing strategy by attempting to block his wind. Hafu ultimately crosses the finish first—although, as he readily admits in the video, Jon may have helped make that victory possible!

The short sequence offers millions of viewers a fun and approachable introduction to radio sailing. It demonstrates that these boats are not simply toys: they require an understanding of wind, strategy, boat handling and racing tactics.

A Submarine Beneath the Pond

The video then moves below the surface with a Thunder Tiger Neptune RC submarine, demonstrated by submarine expert Bob Martin of Nautilus Drydocks.

Bob explains how the submarine’s ballast system takes in water to make the vessel heavier and dive, then expels the water to become buoyant and return to the surface.

As the submarine slowly disappears beneath the pond, Hafu comments on how peaceful and fishlike it looks. Bob agrees that operating an RC submarine can be a surprisingly relaxing experience.

It is a wonderful demonstration of another fascinating corner of the model-boating world—one that combines craftsmanship, electronics, radio systems, propulsion, buoyancy and careful underwater navigation.

Museum-Quality Bismarck

The scale-model side of the hobby is represented by another Argonaut and his highly detailed RC model of the German battleship Bismarck.

Hafu explains that scale modeling is not primarily about achieving the greatest speed. Instead, the goal is to reproduce a real vessel with as much accuracy and detail as possible.

The Bismarck glides across the pond while the camera captures its intricate fittings and realistic appearance. Mateo describes it as looking like a museum piece—and Hafu readily agrees.

For viewers who may associate RC boating only with small, fast powerboats, this segment provides a glimpse into the historical research, patience and model-building skill involved in producing a fine-scale vessel.

Robin’s One-of-a-Kind Hovercraft

Perhaps the most unusual San Diego Argonauts vessel in the entire video is Robin Cahill Simpson’s custom-built hovercraft.

The model is approximately one-tenth scale and is based on the first full-sized hovercraft to cross the English Channel. Robin explains that the project took approximately two or three years to build, followed by another year of solving technical problems and getting it to operate properly.

The result is spectacular.

The hovercraft travels across the pond on a cushion of air, transitions onto land and even performs a spin for the camera. Hafu describes it as looking like a UFO and calls it one of the coolest vessels in the video.

It is believed to be the only operating model of its kind in the world—a wonderful example of the ingenuity, perseverance and craftsmanship found within the San Diego Argonauts.

More Than Boats: Sharing the Hobby With a New Generation

The video is entertaining, energetic and often very funny. But for organizations such as the San Diego Argonauts and all American Model Yachting Association (AMYA) Clubs, it also illustrates something important.

Millions of people—especially young people—may never have seen a competitive RC sailboat, an operating scale warship, a functional RC submarine or a scratch-built hovercraft. A single well-produced YouTube video can introduce the hobby to an audience far larger than any club could reach through a traditional event or advertisement.

In this instance, Hafu Go found the San Diego Argonauts. His team was searching for interesting boats and knowledgeable people, and our members were delighted to welcome them to the pond, provide vessels and help bring the production to life.

But this same opportunity may exist for many other AMYA and model-boating clubs.

There are thousands of YouTube, TikTok, Instagram and other digital creators looking for unusual stories, visually interesting machines, talented builders and authentic experiences. Model-boating clubs have all of those things—as well as colorful personalities, remarkable history and members who love sharing what they know.

Clubs do not necessarily need to wait to be discovered. They can identify creators in their regions, invite them to a sailing day, offer them an opportunity to operate a boat, introduce them to an experienced builder or arrange a friendly race. The strongest collaborations allow creators to tell the story in their own style while club members provide the knowledge, equipment and welcoming environment that make the experience possible.

One creator visit could introduce radio sailing and model boating to hundreds of thousands—or even millions—of potential new enthusiasts.

Welcome to Our Pond

We congratulate Hafu Go and his team on the release and thank them for visiting the San Diego Model Yacht Pond. We also thank the San Diego Argonauts members and other model-boating experts who contributed their time, knowledge and extraordinary vessels to the production.

For our club, it was a memorable day at the pond. For viewers around the world, we hope it will be an invitation to discover the creativity, engineering, camaraderie and sheer fun of model boating.

And for our fellow AMYA clubs, perhaps it will inspire the next great collaboration.

Sometimes the best way to grow our hobby is simply to place a transmitter in someone’s hands—and let the wind, the water and the boats do the rest.

⛵ Tiny Boat, Big Future: The MiniMax RC Sailboat with Creator Brett McCormack

What happens when more than half a century of family boatbuilding tradition meets modern 3D printing, miniature electronics, and a determination to make radio sailing simpler, faster, and more accessible?

You get MiniMax: a remarkably capable, 22-centimeter (about 8.5-inch) radio-controlled sailboat that can be printed, assembled, customized, and raced almost anywhere.

In this San Diego Argonauts conversation, Kerim Baran sits down with MiniMax creator Brett McCormack of Castlerock Yachtworks in Dunedin, New Zealand. Brett’s story begins with a childhood surrounded by yacht design and construction. His father designed and built boats — sometimes in the family living room — and Brett grew up drawing hulls, studying yacht design, building model boats from offcuts, racing dinghies, making sails, and eventually designing and constructing boats of his own.

That lifelong journey led through high-level dinghy sailing, fiberglass construction, International One Metre racing, commercial IOM production, and dozens of experimental Footy designs. One of those projects, Moonshadow, won every heat at an unofficial Footy World Championship. Years later, Brett began exploring what 3D printing could bring to small-scale sailing. His 22-centimeter free-sailing Ocean Mini provided the foundation for an even more ambitious question: How small could a genuinely exciting radio-controlled sailboat be?

MiniMax is Brett’s answer.

A perfect fit for the Argonauts’ school STEM mission

The timing of MiniMax’s launch could hardly be better for the San Diego Argonauts. SDA is expanding its collaboration with local high school STEM, engineering, and robotics programs, using radio-controlled sailboats and robotic race buoys to give students hands-on experience with design, fabrication, electronics, control systems, teamwork, and competition.

MiniMax fits that vision beautifully. Students can work with CAD and STL files, operate 3D printers, compare materials, install tiny servos and receivers, fabricate a keel ballast, build and tune a sail rig, manage a strict weight budget, and then test their decisions on the water. It is a complete engineering project that ends not on a classroom shelf, but on a racecourse.

For a school building a fleet and sharing transmitters among teams, the San Diego pilot budget discussed in the conversation puts each completed boat in roughly the $60–$70 range. Individual hobbyists buying small quantities of every component may spend more, but the project remains unusually affordable for a true two-channel RC sailboat.

Small enough to print. Serious enough to sail.

MiniMax weighs about 120 grams and uses an entire radio system — two servos, receiver, and battery — weighing only about 11 grams. Those numbers create tight design constraints. The boat needs tiny 2-gram servos, a healthy ballast ratio, carefully selected materials, and an efficient rig capable of delivering real performance with very little weight.

The hull and most parts can be printed in PLA+ or PETG, while flexible TPU is recommended for several small rig fittings that need to move yet hold their adjusted position. The full set of parts typically takes approximately five to six hours to print, depending on the machine. Once the parts and materials are ready, Brett estimates about three hours for careful assembly and tuning.

The work is small and precise. On a MiniMax, a quarter-millimeter adjustment can matter. Brett says one of the most important assembly jobs is getting the rudder linkage exactly right. Yet the overall project has an unusually high completion rate because the printed parts locate and fit together as intended. Brett can send someone the files and, two days later, see that person’s new boat sailing online.

From digital file to global one-design class

There are several ways to get started. Builders with access to a 3D printer can purchase the STL license and print their own parts. Kits or printed components are also becoming available through licensed suppliers in different regions, including the United States, United Kingdom, and European Union.

The distributed production model is one of MiniMax’s most interesting innovations. Instead of shipping every boat around the world from New Zealand, the same one-design boat can be manufactured locally from Brett’s files. That reduces shipping costs and international friction while keeping the boats substantially identical.

Purchasing the files is also more than a simple download: it registers the owner as a member of the MiniMax class. Brett maintains a register of licensed owners, and design updates are provided to them.

As of the recording, the digital STL license was discussed at approximately €25, while a more complete regional kit supplied by Brett was discussed at approximately €85, including the license. Prices, availability, kit contents, and suppliers may evolve, so prospective builders should confirm current information directly with Castlerock Yachtworks or a licensed regional supplier.

Why 22 centimeters?

The boat’s size was not chosen arbitrarily. Living in southern New Zealand, Brett knew that most customers would be overseas. He began by studying postal limits: the smallest economical international package, its dimensions, and its allowable weight. Those shipping constraints helped establish the boat’s hull length and total weight budget.

It is a delightful example of real-world engineering: packaging, freight economics, hydrodynamics, electronics, stability, and manufacturability all shaping one product.

A sailboat that races like Mario Kart

MiniMax may be tiny, but it reacts quickly and sails with the character of a much larger yacht. At the same time, the boats are so light that contact generally causes no damage. Brett and a friend tested that proposition enthusiastically — deliberately colliding their boats for half an hour without harming them.

That discovery inspired an informal racing format with almost no right-of-way rules. Establish a start, a finish, and marks that must be rounded; touching another boat or a mark carries no automatic penalty. The racing becomes largely self-regulating because collisions are usually slow. Someone in the growing builder community described it perfectly: the sailing version of Mario Kart.

A course can be compact — perhaps 15 meters long and close to shore — and the boat needs very little water depth. That makes MiniMax particularly promising for schools, camps, small ponds, temporary shallow pools, and other places where conventional RC yachts would be impractical.

Lowering the barriers to radio sailing

Traditional RC yachts can be intimidating to newcomers. Rigging, tuning, terminology, racing rules, transportation, cost, and access to suitable water all create friction. MiniMax removes a surprising amount of it.

The boat is inexpensive enough to build as a fleet, small enough to transport easily, quick enough to assemble while enthusiasm is still high, and forgiving enough to begin racing without first mastering the full Racing Rules of Sailing. It can introduce students, parents and children, model-airplane builders, RC car enthusiasts, sailors, and complete newcomers to the same shared experience.

And although it may look like a toy at first glance, it is much more than that. In Kerim’s words near the close of the conversation: “Tiny boat. Big breeze. Sails like a big yacht.”

Watch the full conversation to hear Brett’s remarkable family story, see the MiniMax parts and rig up close, learn what it takes to print and assemble one, understand the purchasing options around the world, and discover why the San Diego Argonauts believe this little boat could have a very big future in RC sailing and STEM education.

🎙️Argonauts Radio – Episode 14: Are Marbleheads Making a Comeback?

Are Marbleheads making a comeback?

In the latest episode of San Diego Argonauts Radio, Commodore Jess Atkinson sits down with Bruce Andersen, U.S. Marblehead Class Secretary and Chairman of the International Radio Sailing Association (IRSA), for a fascinating conversation about one of the oldest, fastest, and most technologically advanced classes in radio sailing.

Also available on Apple Podcasts:
https://podcasts.apple.com/us/podcast/marbleheads-are-making-a-comeback-trend-or-here-to-stay/id1874110517?i=1000779643020

The Marblehead has a history stretching back nearly a century. Originally developed in Marblehead, Massachusetts, the class evolved from free sailing to vane sailing and eventually radio control. Today’s Marbleheads bear little resemblance to those early boats. At 50 inches long with 800 square inches of sail, modern Marbleheads are lightweight, carbon-fiber, deep-keel racing machines capable of remarkable acceleration and speed.

As Bruce puts it, if tightly controlled classes such as the IOM and DragonForce are the NASCAR of radio sailing, the Marblehead is Formula One.

Jess and Bruce explore the evolution of the class—from the home-built boats that once dominated American radio sailing, through legendary designs such as the Scalpel, to today’s extremely narrow and sophisticated Grunge and Red Ant designs.

They also discuss why Marblehead racing declined in the United States as sailors migrated toward the more easily transported IOM and, later, the DF classes—and why that trend may now be starting to reverse.

New fleets and renewed interest are appearing on both coasts, with experienced IOM sailors increasingly adding Marbleheads to their boat sheds. Regattas are beginning to combine IOM and Marblehead racing, and the Marblehead will be one of the featured classes at San Diego Argonauts Race Week 2027.

And there is a reason sailors keep coming back to them.

They are fast.

Really fast.

Modern Marbleheads feature sophisticated rigs—including their distinctive swing rigs—and acceleration unlike almost anything else in radio sailing. As Jess describes it, sheet in the sail and the boat can take off “like a rocket.”

Bruce and Jess also talk about how newcomers can get involved. Their advice is simple: don’t buy one first—sail one. Come to a Marblehead regatta, introduce yourself, and chances are someone will happily put a transmitter in your hands.

Also in this episode, Jess gives a big shout-out to everyone who helped make the 2026 San Diego Argonauts Open House such a successful “party at the park,” and wraps up with results and highlights from recent ODOM, DF95, and IOM points racing at the Mission Bay Model Yacht Pond.

If you’ve ever wondered why Marblehead sailors become so enthusiastic about these extraordinary boats—or you’re simply curious about the history and evolution of high-performance radio sailing—this is an episode you’ll want to hear.

Are Marbleheads simply enjoying another moment in the spotlight, or are they truly making a comeback?

Give the episode a listen and decide for yourself.

🎪 SDA OPEN HOUSE 2026: A Fantastic Day

Our 2026 San Diego Argonauts Open House is in the books, and what a day it was!

First and foremost, thank you to everyone who volunteered, brought boats, shared their expertise, cooked food, helped with setup and cleanup, or simply spent time welcoming visitors. This event was a tremendous success because of you.

One of the most rewarding aspects of the day was seeing approximately one-quarter of our membership come together to make it happen. Members displayed their boats, taught newcomers how to sail, staffed STEM and Maker exhibits, answered countless questions, cooked lunch, hauled equipment, and made every visitor feel welcome.

The atmosphere at the pond was fantastic from start to finish.

Hundreds of Hands-On Experiences

Throughout the day, visitors had the opportunity to explore nearly every aspect of our hobby.

Beautiful sailboats, scale models, and power boats were on display, while many guests took the controls of an RC sailboat for the very first time.

One of the highlights was watching children—and plenty of adults—go from never having touched an RC sailboat to confidently sailing upwind in just 10 to 15 minutes.

It’s always exciting to see how quickly people discover that RC sailing is both approachable and incredibly rewarding.

STEM & Maker Faire Activities

A special thank-you goes to Jeff Sparksworthy, Rob Wood, Robin Cahill Simpson, and Steve Delva, who created and staffed our STEM and Maker Faire tables.

Visitors explored topics including:

– Electronics and batteries
– Radio control systems
– Glues and adhesives
– Fabrication techniques
– Building methods and tools

These hands-on exhibits sparked countless conversations and demonstrated that our hobby is much more than simply sailing boats—it’s a wonderful blend of engineering, craftsmanship, creativity, and lifelong learning.

Thank You to Our Volunteers

It’s always risky to start naming names because someone deserving is inevitably forgotten, but several members deserve special recognition.

  • Bob and Gil kept everyone well fed with the famous BobDogs.
  • Bill Bridge quietly handled countless behind-the-scenes tasks, including bringing coolers and helping with cleanup.
  • John Scripps made the pizza run happen.
  • Jess Atkinson, Pat Nevitt, and Tom Warren spent much of the day greeting visitors, answering questions, and representing the club.
  • Jon Rogers, Dennis Rogers, Gil, John Scripps, Keith, Steve Ross, Ben, Tom, Pat, and many others generously handed over transmitters and patiently taught visitors the basics of RC sailing throughout the day.

Special recognition also goes to Pat Nevitt and Dave Endert for bringing their beautiful schooners, which attracted plenty of attention.

Looking Toward the Future

One particularly exciting outcome was the attendance of two local high school teachers, who expressed genuine interest in partnering with the San Diego Argonauts on future STEM education programs. They experienced firsthand how RC boats can inspire students to learn about engineering, physics, electronics, and teamwork, and we’re looking forward to continuing those conversations.

Another idea that emerged throughout the day was to host similar events several times each year. Rather than limiting ourselves to one annual Open House, we’d like to organize periodic Learn to RC Sail days focused simply on introducing newcomers to this wonderful hobby.

Thank You!

Finally, thank you once again to every member who helped make this event such a success.

As several members said afterward, this truly was an “Outstanding day at the pond.” The enthusiasm, generosity, and willingness to share our hobby with others reminded all of us what makes the San Diego Argonauts such a special club.

If you took photos or videos during the event, please send us a few of your favorites—we’ll continue updating this recap as more memories from the day come in.

We can’t wait to do it again!

âš“ High School Maritime Robotics & STEM Workshop Day (July 7th, 2026)

Tuesday, July 7, 2026
10:00 AM – 1:00 PM
Mission Bay Model Boat Pond Clubhouse

The San Diego Argonauts are pleased to host our first High School Maritime Robotics & STEM Workshop Day, bringing together educators, mentors, engineers, makers, and experienced builders to explore hands-on skills that can support future maritime robotics and STEM programs for local high schools.

This workshop is part of a broader initiative to expand practical, project-based STEM education opportunities centered around marine technology, robotics, engineering, electronics, fabrication, and model boating.

The July 7 workshop represents the first step in what we hope will become an ongoing program that includes:

  • The development of the RoboBuoy Challenge, a new maritime robotics competition currently being designed for the 2026-2027 school year.
  • A Mentor & OPEN HOUSE Day on August 1, 2026, where students, parents, teachers, engineers, and potential mentors can learn more about model boating, maritime engineering, robotics, and future STEM opportunities at the pond.
  • Continued collaboration with local schools, educators, industry professionals, universities, and STEM organizations throughout San Diego County.

Our goal is simple: create a pathway that allows students to progress from learning basic technical skills, to building increasingly sophisticated maritime robotics projects, and ultimately to competing in a fun, educational, and highly practical engineering challenge.

The proposed RoboBuoy Challenge will encourage students to design, build, and operate autonomous and remotely controlled marine systems while developing real-world skills in engineering, electronics, fabrication, programming, communications, project management, and teamwork.

What You’ll Hear

Brian Shore shares the remarkable story of qualifying for the Worlds after only a handful of IOM regattas and achieving an impressive Top-10 finish. He discusses the challenges of competing against former world champions, adapting to the demanding conditions at Datchet Reservoir, and navigating the intense scrutiny of international measurement inspections.

Peter Feldman reflects on his outstanding fourth-place finish, the mental and tactical challenges of choosing the correct rig in constantly changing conditions, and the preparation required to compete at the highest level of international radio sailing. His insights into fleet management, race strategy, and the grind of a six-day championship offer valuable lessons for sailors of every level.

Gary Boell brings the perspective of one of America’s most experienced international IOM competitors, having represented the United States at World and European Championships for well over a decade. Gary discusses how far the American IOM program has progressed, the camaraderie among the ten U.S. skippers competing in England, and the pride of seeing four American boats sailing in the championship’s final A-Fleet race.

A Strong Showing for Team USA

One of the recurring themes throughout the episode is the continued rise of American IOM sailing. The United States fielded one of its strongest teams ever, with multiple skippers competing at the front of the fleet throughout the event and several finishing among the world’s elite.

The interviews highlight not only the sailing itself, but also the preparation, teamwork, sportsmanship, and dedication required to compete successfully on the world stage. From equipment tuning and rig selection to long race days and international competition, listeners will gain a deeper appreciation for what it takes to race among the best sailors in the world.
