Fleet DNA
How the Japanese boats are built.
230 boats in the fleet. 47 ORC-rated and 183 mapped IRC entries attributed across 11 archetypes — here's how they cluster, and what the collective signature reveals about how Japan races.
Japan's fleet reads as a Farr-anchored Pacific collective with a heavy-air momentum core and a long, full-spectrum structural tail. GRAVITYRUN leads at 20.9% (48 boats) — the heavy-mode momentum platform that carries downwind power through sustained Pacific breeze — with GLIDEFORM close behind at 17.8% (41 boats), the low-drag efficient-flow tier tuned for reaching-angle speed. DEEPFRAME follows at 16.1% (37 boats), the deep-hull, drag-optimized platform that holds efficient flow on Tokyo Bay's mixed-breeze days. No single archetype dominates: all eleven are populated, a full-spectrum distribution that pairs heavy-air offshore inventory for the Sagami Bay swell with efficient coastal speed — and the strongest structural signal sits with the design board, where Farr Design draws nearly a third of the hulls.

Dimension emphasis: Hull Efficiency · Rating & Classification
The 2026 Japanese forward path runs the JSAF domestic circuit and the Kennosuke Cup as the home-water anchor — Tokyo Bay, Sagami Bay, Seto Inland Sea — with Pacific offshore destination campaigns carrying Japanese boats into Rolex Fastnet and US ocean-race venues as the international footprint. Farr Design's concentration — nearly a third of the hulls — is the structural through-line that travels with the fleet.
