Fleet DNA
How the Turkish fleet is built.
380 boats in the fleet. 375 ORC-rated and 5 mapped IRC entries attributed across 8 performance archetypes.
AEROCORE leads the structure by a wide margin, with LEANRUN and LEANFORCE behind it — the top three together carry just over 61% of the fleet.
The Turkish fleet is a large-platform collective shaped by Aegean and Marmara racing, with one family standing well clear at the top. AEROCORE leads the count order at 29.5% (112 boats) — nearly a third of the fleet, and well clear of the family behind it — the large-scale, upright-postured group on a tender righting reserve that forms the cruiser-racer core of the Turkish rank. LEANRUN follows at 18.9% (72 boats), a second large-scale, upright-postured family from the same Large-Platform group. LEANFORCE takes third at 12.6% (48 boats) — the compact-scale family — a single boat ahead of AEROFORCE at 12.4% (47 boats), large, level-postured platforms on a neutral stability reserve, so third and fourth are separated by one hull. Together the three count-order leaders carry 232 of the fleet's 380 boats — 61.1% — a top that has consolidated at the big-boat end even as rapid growth keeps the class mix diverse across the Aegean coast, Marmara region, and Turkish Riviera.

Farr Design anchors the drawing-board signature at 27.6% (105 boats) — a leading share well above the 15% threshold and the deepest single-designer concentration on the Turkish hub, carried through the First 40.7 cluster and the Farr 40 one-design. The 36th Marmaris International Race Week drew a 75-boat scored race group in 2025; the 37th edition runs October 2026 on the same Aegean courses.

AEROCORE leads at 29.5% — the only family clear of a quarter of the fleet — with LEANRUN (18.9%) and LEANFORCE (12.6%) behind it. The 61.1% AEROCORE + LEANRUN + LEANFORCE combined share reads as a top that has consolidated around the large-scale platform core. AEROFORCE (12.4%) sits a single boat behind third, SPARKFLEX (10.3%) holds the minimal-scale seat, and AEROSTREAM (7.1%), KEELRUN (4.7%), and HEFTLINE (4.5%) complete the distribution.
