Fleet DNA
How the Fastnet fleet is built.
208 boats in the fleet. 87 ORC-rated and 121 mapped IRC entries attributed across 11 archetypes; 207 classified, 1 unclassified at the platform-boundary.
The Fastnet fleet runs two clear archetype leaders ahead of a deep, broad mid-pack. GRAVITYRUN leads at 25.5% (53 boats) — the heavy-mode momentum family with strong downwind power in sustained breeze, the archetype the Celtic Sea return leg rewards when the breeze fills in. AEROMAX follows close behind at 23.6% (49 boats) — the power-efficiency hybrid with strong upwind drive and moderate displacement, the family that holds the front when the Channel beats stay honest. AEROBLADE sits third at 13.0% (27 boats) — the light, agile platform optimized for quick acceleration and flat-water speed. Together the top three carry 62.3% of the classified fleet. Below them the field fans out: DEEPFRAME and GLIDEFORM each carry 12.6%, and a long tail (STEELCORE, STEELFORM, HEADFORCE, KEELFLEX, STORMLINE, IRONWIND) covers the remaining 12.6% across six more families.

Farr Design anchors the drawing-board signature at 28.8% (60 of 208 boats) — the largest single share of any fleet on the platform, well above the 15% dominance threshold. The Beneteau First 36.7 (21 boats), First 34.7 (17), First 40 (9), and First 40.7 (6) carry the heart of the Farr-drawn entry list. Johnstone R (J/Boats) follows at 12.0% (25 boats), Judel-Vrolijk at 6.7% (14), and Jeppesen-Nielsen (X-Yachts) at 5.3% (11). The whole fleet participated in Rolex Fastnet Race 2025; 66 of those boats also ran Cowes–Dinard–St Malo in the same UK offshore season.

GRAVITYRUN and AEROMAX lead the Fastnet fleet together — the heavy-momentum downwind family and the powered-up upwind hybrid carrying just under half the classified fleet between them — with AEROBLADE third and the remaining eight families fanning out behind. 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. The downwind-leaning families (GRAVITYRUN plus GLIDEFORM) still carry a substantial structural rollup — consistent with a course whose return leg from the Rock typically runs broad to Cherbourg.
