Hidden Shape
64 boats, a tight three-way Australian signature.
64 boats in the fleet. 57 ORC-rated and 7 mapped IRC entries attributed across 10 archetypes — an AEROBLADE 23.4% + GLIDEFORM 20.3% leading pair (43.7% combined) with IRONWIND at 18.8% close behind, and Farr Design anchoring 20.3% of the drawing-board signature. Here's how the national fleet clusters, and what the collective signature reveals about how Australia races.
Australia races with a light, agile top of the cohort. AEROBLADE leads at 23.4% (15 boats) — the light, agile platform optimized for quick acceleration and flat-water speed — with GLIDEFORM close behind at 20.3% (13), the low-drag hull with efficient upwind flow and moderate displacement. IRONWIND anchors the third pole at 18.8% (12), the stiff, stable-drive platform with predictable load behavior. Together the top three hold 62.5% of the fleet — a structural signature that reflects the Pacific seaboard's mixed menu of Sydney coastal racing, the Tasman, and the Bass Strait crossing to Hobart.

Dimension emphasis: Hull Efficiency · Crew
Farr Design anchors 20.3% of the 64-boat national fleet — the most-represented drawing-board footprint — with the broader Pacific-seaboard menu shaping a light, agile, low-drag signature. The competitive anchor is the Rolex Sydney Hobart, where MIN RIVER took the IRC Division 6 title at the 2025 edition; abroad, the lone Australian entry at the ORC World Championship 2026 in Sorrento — VUDU, a Botin-designed TP-52 — took Class 0 silver, 2.5 points behind the champion.
