Fleet DNA
How the ORC World Fleet is built.
482 boats in the fleet. 479 ORC-rated and 3 mapped IRC entries attributed across 8 performance archetypes.
The ORC World Fleet is a broad-spectrum collective — eight archetypes carry structural weight, and no single hull family commands the circuit. AEROSTREAM leads at 29.7% (143 boats) — the towering-scale, level-trimming upwind-power family that brings TP-52s, Farr 40s, and grand-prix rig drive to the international circuit. AEROCORE follows at 16.2% (78 boats) — the large-platform school at the tender end of the stiffness range, the shape that rewards crews willing to sail a powerful hull on its ear. LEANRUN sits third at 14.9% (72 boats) — the large, upright, low-proportion family of the First 36.7 and J-109 lineage that fills championship entry lists, downwind-neutral in banked race evidence. Together the top three carry 60.8% of the fleet, but the leader is still short of a third on its own — a broad leading band rather than the two-archetype concentration seen in narrower national fleets. Behind them the field is unusually even: HEFTLINE at 9.8% (47 boats), LEANFORCE at 9.5% (46 boats), AEROFORCE at 8.5% (41 boats), and KEELRUN at 7.9% (38 boats) sit within 1.9 points of one another, with SPARKFLEX at 3.5% (17 boats) closing the distribution. There is no thin tail here — every hull family on the platform arrives at the international circuit in numbers.

Dimension emphasis: Comparative Time · Hull Efficiency · Sail Drive · Upwind VMG
Farr Design leads the designer signature at 13.5% (65 boats), ahead of the X-Yachts drawing board at 11.4% (55 boats). Judel-Vrolijk heads the second rank, with Polli next and Frers, Johnstone, and Mills level behind them, and the long tail spreads across Humphreys, Carkeek, Botin, and Cossutti drawing boards. Top classes: X-41 (17), TP-52 (15), First 40.7 (11), First 34.7 (10), Italia 11.98 (9). The marquee event of the current published data is the 2026 ORC World Championship at Sorrento (101 fleet boats in the race group).

AEROSTREAM, AEROCORE, and LEANRUN — the leading trio — together carry 60.8% in a broad leading band, but the fleet spreads across all eight archetypes — the international championship circuit attracts a wider hull range than any single national fleet because each venue rewards a different condition mix. Upwind-biased championship courses bring AEROSTREAM, AEROCORE, and AEROFORCE forward; rough-water legs where stiffness reserve pays elevate HEFTLINE and LEANFORCE; KEELRUN, LEANRUN, and SPARKFLEX hold their share wherever the course mix evens out.
