Eleven islands, six hundred miles, a trade-wind blue-water classic.

The RORC Caribbean 600 is 600 nautical miles around the volcanic Caribbean island chain from English Harbor, Antigua, where trade winds, squalls, and dramatic island wind shadows make a different race every fifty miles. The course rewards hull efficiency on the open-water tradewind legs, crew execution through the physically demanding island roundings, and tactical intelligence in the squall and katabatic-wind game that defines the passages between islands. The Guadeloupe wind shadow downwind of La Soufrière is the race's tactical crucible; the night passages off the volcanic slopes are a second one. FleetEdge tracks 55 boats across four editions admitted to the fleet — the 2024, 2025, and 2026 editions are populated in the analytic record, with the most recent 2026 edition fielding 26 of those 55 boats on the start line in February 2026.

The classified fleet runs AEROBLADE-led at 34% (18 boats), with AEROMAX at 30.2% (16 boats) and DEEPFRAME at 11.3% (6 boats) behind — a blue-water offshore signature. AEROBLADE is the light, agile racing-platform archetype that converts open-water trade-wind reaches into sustained speed; AEROMAX is the power-efficiency hybrid that drives upwind at moderate displacement; DEEPFRAME is the deep-hull stiff platform that runs drag-optimized through chop. The top three archetypes together account for 75.5% of the 53 classified boats — a clear offshore signature where light reaching speed, power-efficient upwind drive, and deep-hull efficiency carry the long passages. GRAVITYRUN and STEELFORM each hold 9.4% (5 boats apiece), with GLIDEFORM, KEELFLEX, and STEELCORE rounding out the eight populated archetypes at one boat each. Two boats lack enough certificate fields for classification. Sixteen countries are represented across the 55-boat fleet, led by GBR (14), USA (10), and FRA (6).

The Caribbean 600 is also an Atlantic-Caribbean campaign — 17 of the 55 fleet boats (30.9%) also raced the 2025 Fastnet. The overlap is structural, not coincidental: programs that target the long winter offshore in the Caribbean often thread the Solent in summer on the same boat and the same crew. Farr Design leads the fleet at 8 boats (14.5%) as the most-common designer, ahead of Rod Johnstone (J/Boats) at 6 (10.9%), Judel-Vrolijk at 5 (9.1%), and Reichel/Pugh, Frers, and Humphreys at 4 apiece. No single board holds the largest share — Farr's lead is real but lives inside the fleet's wider multi-designer mix, and the next edition in February 2027 runs the same 11-island course under whatever trade-wind regime the Atlantic delivers on the day.

AEROBLADE leads the classified fleet at 34% — the light, agile racing-platform archetype that converts open-water trade-wind reaches into sustained speed across the 600 nm Antigua loop. AEROMAX follows close behind at 30.2%, the power-efficiency hybrid that drives upwind at moderate displacement; DEEPFRAME at 11.3% brings deep-hull efficiency through chop. Together the three lead archetypes account for 75.5% of the 53 classified boats — a clear blue-water offshore signature where light reaching speed, power-efficient upwind drive, and deep-hull efficiency carry the long passages between islands. GRAVITYRUN and STEELFORM hold the next tier at 9.4% apiece, with GLIDEFORM, KEELFLEX, and STEELCORE present at one boat each.

Designer Density

Farr Design — the Caribbean 600’s most-common designer.

Farr Design drew 8 of the 55 fleet boats (14.5%) at the RORC Caribbean 600 — the largest single designer share in the fleet, ahead of Rod Johnstone (J/Boats) at 6 boats (10.9%) and Judel-Vrolijk at 5 (9.1%). Reichel/Pugh, Frers, and Humphreys each placed 4 boats, with Ker J at 3 and a long tail of single-board entries from Verdier, Finot-Conq, Mills M, Kouyoumdjian J, and others. Farr’s 14.5% share sits in the “most-common” band rather than the dominant band — in a fleet split across Farr, J/Boats, Judel-Vrolijk, and Reichel/Pugh boards, the Farr Design drawing-board carries the largest single share but no single designer commands the fleet outright. The Caribbean 600 is a multi-designer offshore fleet.

  • Farr Design: 8 boats · 14.5%
  • Rod Johnstone (J/Boats): 6 boats · 10.9%
  • Judel-Vrolijk, Reichel/Pugh, Frers, Humphreys: 7.3–9.1% each
Archetype Density

AEROBLADE leads the Caribbean 600 fleet.

AEROBLADE carries 34% of the classified Caribbean 600 fleet (18 of 53 boats), with AEROMAX close behind at 30.2% (16 boats) and DEEPFRAME at 11.3% (6 boats) — a top-three that accounts for 75.5% of the classified fleet. AEROBLADE is the light, agile racing-platform archetype that delivers the Class 40s, the Ker-46 cluster, and the J/Boats performance hulls to the fleet — the platforms that convert open-water trade-wind reaches into sustained speed. AEROMAX brings power-efficient upwind drive at moderate displacement, a near-equal second share that gives the fleet a paired light-platform and power-hybrid front tier; DEEPFRAME brings deep-hull efficiency for the drag-dominated long-reach legs. The Caribbean 600 is a blue-water offshore signature — light reaching speed and power-efficient upwind drive leading the fleet, deep-hull efficiency behind them. GRAVITYRUN and STEELFORM follow at 9.4% each, with STEELCORE, KEELFLEX, and GLIDEFORM present at one boat apiece.

  • AEROBLADE: 18 boats · 34%
  • AEROMAX: 16 boats · 30.2%
  • DEEPFRAME: 6 boats · 11.3% — top three = 75.5% of classified

Performance Verdict

INO NOIR converts a Ker-46 platform into third overall.

INO NOIR (Ker-46, Ker J, AEROBLADE, GBR) finished 3rd of 26 in IRC Overall at the 2026 Caribbean 600 — the best published result by any boat in the fleet at this running. The result is platform-consistent rather than platform-defying: the Ker-46 sits 3rd on the fleet’s Downwind VMG-12kt board at 8.02 kn, 4th on Upwind VMG-12kt at 6.47 kn, and carries the third-fastest rated pace in the fleet at 458.5 GPH sec/nm — a 46-footer holding podium dimensional presence in a fleet headed by a 100-foot Super Maxi and a Volvo 70. The boat’s physics said front-of-fleet; the corrected scoreboard agreed.

  • IRC Overall: 3rd of 26 · published 2026 standing
  • Downwind VMG-12kt: 8.02 kn · 3rd of 26
  • Rated pace: 458.5 GPH sec/nm · 3rd of 25
Multi-Dimension Presence

BLACK JACK 100 stacks Sail Drive, rated pace, and both VMG-12kt boards.

BLACK JACK 100 (Super Maxi 100, Reichel/Pugh, AEROBLADE) tops four Caribbean 600 fleet Headlines at once — Sail Drive Index at 60 (11 points clear of AEGIR), Upwind VMG-12kt at 8.84 kn, Downwind VMG-12kt at 11.55 kn (2.97 kn clear of AEGIR), and the fleet’s fastest rated pace at 325.2 GPH sec/nm. The 100-foot Super Maxi is the only boat in the 2026 fleet to lead four separate dimension families across the same race, and it backs the physics boards with a −55.54 sec/nm allowance delta — 3rd on the comparative board. On a course where the open-water trade-wind reaches reward sustained drive and the island-cluster pointing sections reward upwind VMG, the AEROBLADE Super Maxi converts length and rig power into a leading dimensional position across both points of sail.

  • Sail Drive: 60 · 1st of 9 (11 clear of AEGIR)
  • Upwind / Downwind VMG-12kt: 8.84 / 11.55 kn · 1st of 26 on both
  • Rated pace: 325.2 GPH sec/nm · fastest of 25
Magnitude Gap

SCOWLING DRAGON runs 27.7 sec/nm faster than the comparative median.

SCOWLING DRAGON (Class 40, Owen Clarke design, DEEPFRAME, USA) led the 2026 comparative-allowance field at −69.92 sec/nm vs the ORC median — 5.1 sec/nm clear of RIKKI (RP-42, Reichel/Pugh) at −64.85 and 27.7 sec/nm faster than the 11-boat comparative field’s median of −42.21. The 40-foot offshore one-design out-sailed its allowance harder than the maxis behind it — BLACK JACK 100 took 3rd on the board at −55.54 — the signature of a planing-capable shorthanded platform set up for exactly the sustained open-water reaching the Antigua loop serves. Over 600 nm, a 27.7 sec/nm edge over the median compounds to better than four and a half hours of corrected time.

  • 1st: SCOWLING DRAGON · −69.92 sec/nm · DEEPFRAME
  • 2nd: RIKKI · −64.85 sec/nm · 5.1 sec/nm gap
  • Comparative-field median: −42.21 sec/nm · 11 of 26 boats
Composition Shift

The DEEPFRAME shift in the 2026 starting list.

The 2026 starting list shifts the archetype mix from the fleet baseline: where the 53 classified boats run AEROBLADE-led at 34% with AEROMAX close at 30.2% and DEEPFRAME at 11.3%, the 24 classified boats at the 2026 running compress to AEROBLADE 8, then DEEPFRAME and GRAVITYRUN tied at 6 apiece. DEEPFRAME climbs well past its fleet share at event scope — the deep-hull, drag-optimized platforms turned out at a higher rate for this edition than the fleet baseline predicts — while AEROMAX, the near-co-leader across the whole fleet, fielded only two boats at this running. The shift is real but mild: the 2026 starting list still reads as a subset of the broader fleet because that fleet IS the Caribbean 600, edition by edition — the 2024 edition fielded 20 boats, 2025 fielded 23, and 2026 fielded 26.

  • Fleet baseline (53 classified): AEROBLADE 34% · AEROMAX 30.2% · DEEPFRAME 11.3%
  • 2026 cohort (24 classified): AEROBLADE 8 · DEEPFRAME 6 · GRAVITYRUN 6
  • Editions populated: 2024 (20) · 2025 (23) · 2026 (26)
