Fleet DNA
How the Sydney Hobart fleet is built.
76 boats in the fleet — 61 ORC-rated and 15 IRC entries carried via the IRC-to-ORC mapping process. 75 classified across 8 archetypes, 1 unclassified at the platform-boundary.
The Sydney Hobart fleet is a balanced offshore collective with a light-rig leader rather than a single dominant recipe. AEROBLADE holds the largest share at 25.0% (19 boats) — the refined-rig, light-and-agile platforms tuned for quick acceleration and clean trim response. DEEPFRAME sits a step behind at 23.7% (18 boats) — deep-hull, stiff platforms that hold a powered, drag-optimized line when the southerly buster fills in — with AEROMAX at 17.1% (13 boats), the power-efficiency hybrids with strong upwind drive, and STEELFORM at 14.5% (11 boats), the heavy-displacement hulls with strong directional stability that suit the long Bass Strait passage. Together the top three archetypes carry 65.8% of the 76-boat fleet — a structurally diverse signature where the top two each hold more than a fifth of the fleet and no single recipe dominates.

Farr Design is the fleet’s most-common drawing board at 17.1% (13 boats) in a fleet spread across many design offices. Top classes: First 40 (3) and Sydney 38 (3) — the only classes 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.

AEROBLADE’s 25.0% share leads a balanced fleet, not a dominated one — the top three families (AEROBLADE, DEEPFRAME 23.7%, AEROMAX 17.1%) lead a balanced spread, with STEELFORM at 14.5% behind them. The Sydney Hobart fleet says something specific about what the Bass Strait demands: refined-rig agility for the shifts, deep-hull stiffness for the powered upwind line when the southerly buster fills in, power-efficiency upwind drive, and heavy-displacement directional stability for the long Tasman passage. Eight archetype families are populated; three of the eleven canonical archetypes (STEELCORE, KEELFLEX, and STORMLINE) do not appear in this fleet at all.
