Fleet DNA
How the Baltic Offshore fleet is built.
1,814 boats in the fleet. The classified boats are attributed across the eight archetypes of the 2026 census — eleven measured slots — with 3 unclassified hulls held aside.
The Baltic is a compact-hull fleet with a clear head: LEANFORCE takes a quarter of the roster on its own, and with LEANRUN and SPARKFLEX the leading tier carries more than half the fleet. LEANFORCE leads at 25.4% (461 boats) — the compact hulls that keep driving when the Baltic chop builds and the breeze holds in. LEANRUN follows at 20.7% (376 boats), the all-rounders, First 36.7s and J-109s, that the race results read as upwind-neutral through a Nordic racing day. SPARKFLEX sits third at 14.3% (259 boats): the minimal-scale, tender-reserve one-designs, the J-80s, J-24s, and J-70s that reward the crew discipline this fleet is built on. AEROCORE is close behind at 11.5% (209 boats), the large-scale hulls that read as downwind-neutral in race results, ahead of AEROFORCE at 10.4% (188 boats), the level-posture group that grinds out the upwind ladder, then AEROSTREAM at 5.7% (103 boats), HEFTLINE at 6.6% (120 boats), and KEELRUN at 5.2% (95 boats) — a long, evenly-packed tail behind a top tier that is anything but flat.

The Baltic is led from the compact end and backed by breadth. LEANFORCE takes 25.4% of the fleet on its own, and with LEANRUN and SPARKFLEX the leading tier carries more than half the roster; the remaining archetypes pack into a band from 5.2% to 11.5%. The Baltic's signal is a clear head over a long, even tail — a structurally diverse domestic roster in which one compact hull family sets the pace.
