Six hundred and ninety-five miles. The Solent, the Channel, the Rock, Cherbourg.

The Rolex Fastnet Race is the biennial RORC offshore classic that founded modern offshore racing in 1925 and staged its centenary edition in July 2025. Cowes to Cherbourg via the Fastnet Rock — 695 nautical miles around the south coast of England, across the Celtic Sea to the rock off the southwest tip of Ireland, and back across the Channel to Cherbourg. The course rewards no single boat trait: tidal-gate timing at Portland Bill and the Needles, breeze management across the Channel, displacement management around the Rock, and crew endurance back to the French coast.

FleetEdge tracks 210 boats in the Fastnet 2025 fleet — ORC-rated hulls and IRC-rated hulls together, analyzed through the same physics framework. Ninety-three carry ORC measurement certificates; 117 are IRC entries projected as ORC-mapped IRC entries using FleetEdge's IRC-to-ORC mapping, matched to their ORC design-family equivalents by hull dimensions and rated with the full ORC physics profile. Every mapped entry is transparently labeled as a class-sibling projection. Both rating populations sit on the same comparative-time, hull-efficiency, and crew-residual axes — one of the deepest cross-rating analytical datasets on the offshore circuit.

The front of the fleet is a tight contest of big platforms. AEROSTREAM leads at 19.5% (41 boats) — the towering-scale family whose banked race evidence carries a measured downwind advantage. LEANRUN is second at 18.1% (38 boats), the large-scale, upright-posture cruiser-racer core of the entry list, and HEFTLINE is third at 16.2% (34 boats), the compact, level-postured family, reaching-neutral in banked race evidence. The leading three hold 113 of the 210 boats, and the order stays tight behind them — AEROCORE at 15.2% (32 boats) and AEROFORCE at 14.3% (30 boats) hold the middle band above 14% of the entry, while LEANFORCE, KEELRUN, and SPARKFLEX close the tail. The Fastnet still draws a wider hull range than a single-venue championship; at this cut no archetype holds even a quarter of the entry. The geographic backbone is British and French — GBR sail numbers form the largest national bloc with FRA close behind, and Germany, the Netherlands, and Norway carry the secondary tier across 20 countries in total. The Fastnet 2025 fleet also overlaps heavily with the Cowes Offshore Series — 68 of the 210 boats double-ran Cowes–Dinard–St Malo, and 52 ran the Myth of Malham, signaling a tightly scheduled UK and French offshore season around the centenary race.

Rolex Fastnet Race 2025 — Overall.

All 210 of the 210 fleet boats competed. 695 nautical miles point-to-point, Cowes to Cherbourg via the Fastnet Rock. One race, IRC overall scoring across nine IRC divisions. 26 July 2025. 93 boats carry full ORC measurement; 117 are IRC-rated and projected as ORC-mapped IRC entries on the same comparative-time axis.

Dimension leaders — the 210-boat Fastnet fleet.

Cohort-relative leaders from the Rolex Fastnet Race 2025 (26 July 2025) publication. Finish order comes from the IRC overall standings; Comparative Time is the corrected sec/nm delta against the fleet’s ORC-median allowance (negative = faster than the rating expects); Crew Residual is the sec/nm gap between actual pace and the boat’s archetype-expected pace (negative = the crew beat that expectation). 93 of the 210 boats carry comparative-time and crew-residual records; both rating populations sit on the same axis via the IRC-to-ORC mapping process.

Championship Citation

LEON — Rolex Fastnet Race 2025 Winner, IRC 2 and IRC Overall

LEON AEROCORE, the French JPK-1050 (FRA 53524), won the 40-boat IRC 2 division and the Rolex Fastnet Race 2025 overall on corrected time — a mid-size division boat taking the whole event at the centenary running of the race. The win is backed by the physics: LEON’s corrected pace came in 77.8 sec/nm faster than the fleet’s ORC-median allowance expectation over the 695-mile course — among the largest comparative-time deltas in the comparison group — and the crew-residual view carries the same signal, with LEON’s execution in the 99th percentile of that group. An AEROCORE hull — the large-scale, upright-posture, tender-reserve family — sailed past its platform expectation from the Solent to Cherbourg. The counterpoint sits at the top of the rating band: SHK SCALLYWAG, the Super Maxi rated at an IRC TCC of 1.95, posted the fastest elapsed time of any named finisher in the published standings — and corrected to 225th overall, 6th of 9 in IRC Super Zero. That is corrected time doing its job: at the highest ratings only an enormous real-time margin wins on handicap, and this year the race was won from IRC 2, not from the maxi division.

Nationality / Class Cluster

A French one-two at the front of the IRC standings.

France took the top two steps of the Fastnet 2025 IRC overall standings. LEON AEROCORE (JPK-1050) finished first and LANN AEL 3 LEANRUN (First 35, FRA 346) second — two French production cruiser-racers ahead of every grand-prix program in the 210-boat FleetEdge fleet. Both sailed out of the same 40-boat IRC 2 division, and the cluster runs deeper than the podium: the French shorthanded-offshore lineage — JPK 10.30s and 10.50s, Sun Fasts, and the First family — is concentrated in the front half of the standings. The Fastnet is the RORC’s home race, but at this edition the French offshore school owned the top of the corrected-time table.

  • IRC Overall 1st: LEON · FRA · JPK-1050
  • IRC Overall 2nd: LANN AEL 3 · FRA · First 35
  • Both from IRC 2: 1st and 2nd of 40
Archetype-Conditions Dominance

AEROSTREAM stacked the classified big-boat divisions at this running of the race.

At this running of the Fastnet, read through the FleetEdge archetype view published nearest the race, AEROSTREAM tied for the largest classified family — 26 of 93 boats (28.0%) — and it owned the grand-prix end of the entry: every classified hull in IRC Zero and in the leading Admiral’s Cup division carries the AEROSTREAM assignment, along with the lone classified Super Zero maxi and three of six in the second Admiral’s Cup division. That grip on the big-boat classes is composition, not destiny: in the conditions that prevailed on the 2025 course the overall prize still went to an AEROCORE hull sailing out of IRC 2. The towering, rig-powered platforms convert when the beats out of the Solent and back across the Channel stay honest — a different pressure pattern across the Celtic Sea would reward a different hull family, and the race’s own history says no archetype owns the Rock.

  • AEROSTREAM at this vintage: 26 of 93 · 28.0%
  • IRC Zero: 5 of 5 classified · Admiral’s Cup 1: 4 of 4 · Admiral’s Cup 2: 3 of 6
  • Overall winner: LEON · AEROCORE · IRC 2
Magnitude Gap

BEAU IDEAL: 39 sec/nm clear of the ORC median from 12th overall.

BEAU IDEAL AEROSTREAM, the Botin 41 flying the British Virgin Islands flag (IVB 2047), converted a 39.4 sec/nm comparative-time advantage over the fleet’s ORC-median expectation into 12th in the IRC overall standings from the Admiral’s Cup 2 division. Over 695 miles that delta compounds to better than seven and a half hours against a median-pace boat — an AEROSTREAM platform running near the top of its conversion envelope. The gap sits in the 91st percentile of the fleet’s comparison group on a single-race basis — the cleanest big-boat magnitude signal in the 2025 publication.

Archetype assignments dated 2026-08-20 — the FleetEdge analysis nearest this event.

Of the 210-boat fleet, 93 carry a FleetEdge archetype assignment at this vintage — the FleetEdge view published nearest the 2025 race. The classified group leans powered-up: AEROSTREAM and AEROCORE lead tied at 26 boats apiece — each just over a quarter of the classified group — with HEFTLINE and LEANRUN tied at 12 apiece, each archetype counted across all of its cards in the grid below. What the entry structure adds is a stacked top end — the classified big-boat divisions, IRC Zero and the leading Admiral’s Cup class, are AEROSTREAM throughout, while the overall winner sailed an AEROCORE hull out of IRC 2.

210 boats in the fleet. 93 ORC-rated and 117 mapped IRC entries attributed across eight archetypes; 210 classified.

The Rolex Fastnet Fleet Signature

The Fastnet fleet is led from the front by its big platforms. AEROSTREAM leads at 19.5% (41 boats) — the towering-scale, stiff-reserve family whose banked race evidence carries a measured downwind advantage. LEANRUN is second at 18.1% (38 boats), large-scale hulls on an upright posture — the offshore cruiser-racer core of the entry list. HEFTLINE is third at 16.2% (34 boats), the compact, level-postured family, reaching-neutral in its banked race evidence. The order stays tight behind the podium: AEROCORE at 15.2% (32 boats) and AEROFORCE at 14.3% (30 boats) hold the middle band, with LEANFORCE at 8.1% (17 boats), KEELRUN at 7.1% (15 boats), and SPARKFLEX closing the tail.

Farr Design anchors the drawing-board signature at 30.5% (64 boats) — one of the deepest single-designer concentrations on the platform. The Beneteau First 34.7 (25 boats), First 36.7 (21), First 40 (9), and First 40.7 (6) carry the heart of the Farr-drawn entry list, and the Johnstone-designed J-105 (10 boats) leads the classes outside the Farr stable. The whole fleet participated in Rolex Fastnet Race 2025; 68 of those boats also ran Cowes–Dinard–St Malo in the same UK offshore season.

AEROSTREAM leads the Fastnet fleet, with LEANRUN and HEFTLINE directly behind it and AEROCORE and AEROFORCE within two points of the podium. The Fastnet pulls in a wider hull range than any narrower championship venue because the 695-mile point-to-point course mixes tidal-gate strategy, Channel light air, Celtic Sea exposure, and a final cross-Channel sprint. That range shows up as breadth at the front rather than a runaway leader: the leading archetypes each hold more than 14% of the entry, and no family reaches a quarter of the fleet.

Designer Density

Farr Design anchors three in every ten Fastnet hulls.

Farr Design leads the Fastnet drawing-board signature at 30.5% (64 of 210 boats) — one of the deepest single-designer concentrations on the platform. The Farr-drawn Beneteau First family carries the heart of the fleet: First 34.7 (25 boats), First 36.7 (21), First 40 (9), and First 40.7 (6) account for 61 boats together, and the Johnstone-designed J-105 (10 boats) is the largest class outside the Farr stable. The Farr signature — moderate displacement, crew-balanced cruiser-racer hulls — is the structural backbone of the fleet’s mid-size divisions. Nowhere else on the FleetEdge platform does one drawing board concentrate the French-and-British club-racer base the way Farr Design does on the Fastnet course.

  • Farr Design: 64 boats · 30.5%
  • Beneteau First cluster (34.7 / 36.7 / 40 / 40.7): 61 boats
  • Largest non-Farr class: J-105 · 10 boats
Archetype Density

A tight five-family front rank, led by AEROSTREAM.

AEROSTREAM leads the Fastnet fleet at 19.5% (41 of 210 boats), with LEANRUN second at 18.1% (38 boats) and HEFTLINE third at 16.2% (34 boats). The towering AEROSTREAM platforms carry a measured downwind advantage in banked race evidence; the LEANRUN and HEFTLINE groups behind them are the cruiser-racer core the Fastnet has drawn for a century. The order stays tight past the podium — AEROCORE at 15.2% (32 boats) and AEROFORCE at 14.3% (30 boats) keep five archetypes above 14% of the entry — while LEANFORCE at 8.1% (17 boats), KEELRUN at 7.1% (15 boats), and SPARKFLEX at 1.4% (3 boats) close the tail. The 695-mile point-to-point course sets a broad, flat front rank over a varied chasing field.

  • LEANRUN: 38 boats · 18.1%
  • HEFTLINE: 34 boats · 16.2%

The boats that define Fastnet racing.

First 34.7 (25)

The compact Beneteau Farr-drawn racer-cruiser — the largest single class in the Fastnet 2025 fleet, a sub-12m offshore mainstay with strong French and British shorthanded representation.

First 36.7 (21)

The Beneteau Farr-drawn one-design racer-cruiser — a fixture of Channel offshore racing and the second-largest class in the fleet.

J-105 (10)

The Johnstone-designed J/Boats sportboat — an offshore-rated one-design with strong American and British representation.

First 40 (9)

The Beneteau First 40 racer-cruiser — the larger Farr-drawn cousin and a repeat RORC offshore campaigner.

First 40.7 (6)

The Farr-drawn First 40.7 — the long-serving IRC crossover that still anchors club offshore programs.
