How the Class40 Scow is Reinventing IRC Offshore Racing

The breakthrough that changed everything

January 2026, off Grenada. A 50-footer nobody saw coming crosses the finish line of the RORC Transatlantic Race as overall winner. Palanad 4 — a name still unknown in IRC circles — has just devoured 3,000 miles in 8 days, 5 hours, 55 minutes and 50 seconds, at an average speed of 15 knots. Behind her, maxis twice as long and professional crews of 12 to 15 sailors wondering what just hit them.

Seven people aboard. A 15.20-meter boat. Only her second offshore race.

A month later, the same scenario repeats: the RORC Caribbean 600 falls to this same floating UFO, this time in IRC Zero. And here's the kicker: a course made up of 60% upwind angles. Finish time: 2 days, 10 hours, 32 minutes. The kind of result that ends all debate.

To measure the magnitude of the earthquake? Let's compare. Two years earlier, Olivier Magré crossed this same transatlantic finish line at the helm of his Palanad 3, a Class40, in 10 days and 2 hours. Palanad 4 was roughly 30% faster than her predecessor. Same course. Same skipper. But with a boat born of a very particular lineage.

From Class40 to Mach 50: a revolutionary lineage

The story begins in the cockpit of a Class40. Palanad 3, sail number 160, is a Mach 40.4 designed by Sam Manuard. In 2024, Magré takes her to victory in the RORC Transatlantic in the Class40 category. Clean win, flawless execution. But above all, a revelation: the scow concept works beyond all expectations.

What comes next? Magré orders the Mach 50 from Manuard. Same philosophy, bigger scale. The brief in one sentence: transpose the scow bow to a 50-footer built for the RORC circuit. Budget: around 2 million euros. Construction assigned to JPS Production. Launch on July 19, 2025.

Six months later, the boat demolishes the IRC competition.

But what gives this trajectory its particular flavor is the human dimension. Magré doesn't race alone. His son is part of the crew. And when he crosses the line in Grenada, his words say it all:

"For me, as a father, it's a fantastic dream. Winning the RORC Transatlantic with my son is the greatest result I can imagine in sailing."

Hard to find a better validation of a sporting and family project.

The Manuard-Magré partnership

The relationship between architect and owner deserves attention. Manuard doesn't design to exploit a rating loophole. He says it himself:

"Palanad was created not to exploit a rating flaw, but to provide maximum pleasure."

This philosophy — pleasure as a performance driver — runs through the entire project. And it finds its direct origin in the full-scale laboratory that the Class40 has become.

The scow bow: anatomy of a technical disruption

What makes Palanad 4 so radically different? Her bow. Wide, flat, almost provocative. Purists find it ugly. Those who've sailed on it never want to get off.

The hydrodynamic principle is both simple and counterintuitive. Manuard explains it without ambiguity:

"The concept of the round bow is to avoid burying the front underwater. The bow is so wide and so flat that it creates hydrodynamic lift that also helps the boat punch out of waves."

In practical terms? Where a conventional monohull buries itself in the swell — sometimes violently — the scow lifts her nose and surfs. Result:

  • Speeds regularly above 20 knots surfing
  • Peaks at 25 knots
  • Dry deck even in muscular downwind conditions
  • Interior volumes comparable to a catamaran or much larger monohull

The IRC rating confirms the positioning: with a TCC of 1.426, Palanad 4 sits in the TP52 zone (1.360-1.400), but requires half the crew. Seven sailors versus twelve to fifteen. Do the math in terms of payroll, logistics, fatigue.

Because this may be the scow's most underestimated secret. Comfort isn't a luxury, it's a performance multiplier:

"Even at 20-25 knots downwind, the deck remains remarkably dry. Comfort is performance. When the crew can stay focused, the boat goes faster."

The concept's limits

Okay. Let's be honest: the scow isn't invincible. Her Achilles heel? Light air and choppy seas. The significant wetted surface of that outsized bow becomes a brake when the wind drops and chop sets in. Palanad 4's crew acknowledges it without hesitation: the boat's weak point isn't upwind — it's the calm.

A weakness that explains why victory in the Caribbean 600, with its 60% upwind in varied conditions, constitutes such a powerful validation. The boat doesn't only win when it's blowing.

Class40: the laboratory that changed everything

Palanad 4 isn't a Class40. But she wouldn't exist without the Class40. This one-design class, originally conceived to democratize offshore racing, has become — almost despite itself — the most formidable innovation incubator in offshore sailing.

The numbers speak for themselves:

  • 56 scows built since 2019
  • 43% of the active fleet in 2024
  • 31 rating certificates issued for scows in 2025, versus 23 for conventional-bow boats
  • Record of 21 launches in 2023

The innovation pipeline is clear: Mini 6.50 → Class40 → IRC 50-footers. Each step validates, refines, pushes the concept's limits. The three leading designs of 2025 — Manuard's Mach 40.6, Marc Lombard's Lift V3, Michel Desjoyeaux's Agité 40 — are all scows. The debate is no longer "scow or not scow." It's in the details.

Gianluca Guelfi, architect of the Musa 40, sums up the situation:

"The differences between boats are less and less significant... the difference will come down to details."

Greg Leonard's Mach 40.6 Swift, winner of the 2025 Round Ireland Race, illustrates this pursuit of detail: targeted improvements in reaching angles between 60° and 110° TWA, where miles are won in offshore racing. And what about Crédit Mutuel #158, a 2019 Lift V2 — six years old! — still second in the 2024 Transat CIC and winner of the 2025 CIC Med Channel? Proof that the scow ages well.

If this technical revolution fascinates you, you can follow it closely — several Class40s are open to sponsorship on spencer.club, where you'll discover how these high-performance machines compete in races.

The IRC opportunity window is closing

Here's the paradox. The scow is so effective in IRC that it's attracting the attention of the rule's guardians. Ludovic Abollivier, director of the IRC rating office, doesn't mince words:

"It is very likely that additional taxation will be adopted in 2027."

Translation: enjoy it while it lasts. The 2026-2027 window represents a unique opportunity for scow owners — and particularly for early adopters of the 50-foot concept like Magré. After that? The rating will tighten, the advantage will shrink.

This prospect has direct consequences on the market. Used Class40 scows currently trade around 650,000 euros — close to new price, which says a lot about demand. But Cédric de Kervenoaël, president of the Class40, anticipates a correction:

"The price of scows will drop a bit and everything will become more affordable again."

A prediction that could accelerate if the 2027 IRC taxation cools the enthusiasm of results-oriented owners. Paradoxically, this correction would make the scow more accessible to amateur owner-racers — the class's historical core.

Pogo exits, the market recomposes

The other shockwave of 2025? Pogo Structures' withdrawal from the Class40. A turning point. Pogo was volume, production, democratic access to offshore. Its departure reconfigures the entire supply chain.

Who's taking over? JPS Production — the same yard that built Palanad 4 — CDK Technologies, and a handful of boutique yards. The market is consolidating around more specialized players, capable of producing at a rate of 7 to 8 units per year. Far from the 2023 peak, certainly, but sufficient to maintain a vibrant fleet.

This maturity has an interesting side effect: the emergence of a "performance-cruising" market. The scow's generous interior volumes — comparable to those of a catamaran — are attracting a clientele that isn't aiming for the podium but wants to cross fast, comfortably, safely. The scow could well become the SUV of offshore sailing — a comparison Manuard would probably reject, but which reflects a commercial reality.

When Class40 innovation irrigates all offshore racing

Back to Palanad 4. What does she prove, ultimately?

That the scow isn't a Class40 artifact. Not a niche concept optimized for a specific rule. It's a design paradigm that works at all scales — from the Mini 6.50 to the 50-foot IRC, via the Class40 that served as a full-scale test bench.

The transmission chain is now complete. Architects test in Minis, industrialize in Class40s, and — when confidence is there, when a bold owner signs the check — project the concept into the IRC arena where maxis and TP52s have made the rules for decades. And it works.

Olivier Magré and his crew sum up the experience with infectious jubilation:

"We really had a blast, going fast without tiring ourselves out. Palanad's aesthetics may shock some purists, but to try it is to adopt it!"

What will be the next innovation to emerge from the Class40 laboratory? Democratized retractable foils? New construction materials? Partial automation for solo races? Hard to predict. But one thing is certain: anyone who wants to understand where offshore racing is heading in five years would do well to watch what's happening today on Class40 start lines. And to miss none of these developments, find all the dates of upcoming showdowns on the spencer.club calendar.

The scow first made people smile. Then it made them think. Now it's winning — at all scales. And that, frankly, is a revolution.
