Fleet DNA
How the Sydney Hobart fleet is built.
72 boats in the fleet — 65 ORC-rated and 7 IRC entries carried via the IRC-to-ORC mapping process. 70 classified across 10 archetypes, 2 unclassified at the platform-boundary.
The Sydney Hobart fleet is a balanced offshore collective with a deep-hull leader rather than a single dominant recipe. DEEPFRAME holds the largest share at 24.3% (17 of 70 classified) — deep-hull, stiff platforms that hold a powered, drag-optimized line when the southerly buster fills in. AEROBLADE sits a step behind at 22.2% (16 boats) — the refined-rig, light-and-agile platforms tuned for quick acceleration and clean trim response — with AEROMAX at 15.3% (11 boats), the power-efficiency hybrids with strong upwind drive, and STEELFORM at 13.9% (10 boats), the heavy-displacement hulls with strong directional stability that suit the long Bass Strait passage. Together the top three archetypes carry 62.9% of the classified fleet — a spread, structurally diverse signature where four families each clear the 14% mark.

Farr Design is the fleet’s most-common drawing board at 12.9% (9 of 70 classified) in a fleet spread across many design offices. Top class: Sydney 38 (3) — the only class with three or more hulls in the fleet. The 81st edition starts Boxing Day 2026 under the same Bass Strait weather clock the fleet has been reading for eighty years.

DEEPFRAME’s 24.3% share leads a balanced fleet, not a dominated one — four archetype families (DEEPFRAME, AEROBLADE 22.9%, AEROMAX 15.7%, STEELFORM 14.3%) each clear the 14% mark. The Sydney Hobart fleet says something specific about what the Bass Strait demands: deep-hull stiffness for the powered upwind line when the southerly buster fills in, refined-rig agility for the shifts, power-efficiency upwind drive, and heavy-displacement directional stability for the long Tasman passage. Ten archetype families are populated; one of the eleven canonical archetypes (STEELCORE) does not appear in this fleet at all.
