KEELRUN, the compact upright-riding platform, leads the fleet — a quarter of the hulls — with SPARKFLEX close behind and HEFTLINE third: a broad Alpine-lake top tier, and a distinctive signature on FleetEdge.

Kinship

A KEELRUN-led Alpine-lake fleet — the compact upright-riding platform takes a quarter of the hulls, SPARKFLEX the minimal-scale small-keelboat second.

Switzerland's 192-boat fleet — 185 ORC-rated plus 7 mapped IRC entries — carries a distinctive KEELRUN-led lake-racing signature: KEELRUN takes a quarter of the hulls, with SPARKFLEX close behind and HEFTLINE third — the compact upright-riding platform leading the minimal-scale small-keelboat and the compact stiff-hulled racer — a broad top tier shaped by Alpine-lake racing.

ORC Authority: Swiss Sailing · Swiss Rating Office

Swiss Sailing and the Swiss Rating Office govern 192 SUI/CHE-flagged hulls in the FleetEdge fleet — 185 ORC-rated boats plus 7 mapped IRC entries, a near-pure-ORC national fleet shaped by light-wind Alpine-lake racing first, offshore racing second. Lac Léman, Lake Zürich and Lake Constance are the home waters; the Mediterranean, the Adriatic, and European championship venues are the away circuit. The national fleet does not dominate any one event on participation, but it does carry championship firepower at the grand-prix end — and its archetype signature is unlike any other landlocked or coastal fleet on FleetEdge because the lake conditions select for hull characteristics no offshore venue rewards in the same way.

The signal is a broad Alpine-lake top tier rather than one dominant anchor. KEELRUN leads — a quarter of the fleet's hulls — with SPARKFLEX close behind and HEFTLINE third. KEELRUN is the compact, upright-riding platform on a neutral righting reserve, reaching-neutral in banked race evidence — the club-keelboat tier that fills Swiss lake racing; SPARKFLEX is the minimal-scale, upright-riding platform on a tender righting reserve, the one-design and sportboat profile owners pick for short flat-water courses; HEFTLINE is the compact, level-riding stiff-reserve platform, the modern compact-racer profile. LEANFORCE, a compact-scale grouping, follows in fourth. At the drawing-board level, Felci U leads — Felci's Italian-school lake-and-Mediterranean range the most-represented design voice in the fleet. The archetype concentration is a long-running structural preference read directly from the fleet composition.

The 2026 Swiss forward path runs the Alpine-lake championship circuit first, with the ESSE 850 one-design fleet, the Psaros 33 grand-prix lake class, and the Lacustre classics carrying Lac Léman, Zürich and Constance club racing through the season, and KAJSA III's Copa del Rey defense the international title target the country has already proven it can win. From the lakes to the Mediterranean, in that order.

Hidden Shape

The shape of the Swiss fleet.

192 Swiss boats across 8 archetypes — here's how they cluster, and what the collective signature reveals about Alpine-lake racing and Mediterranean grand-prix campaigns.

The Swiss ORC Fleet Signature

Switzerland's fleet is a KEELRUN-led Alpine-lake collective — a broad top tier rather than one dominant anchor. KEELRUN leads at 25.0% (48 boats) — the compact, upright-riding platform on a neutral righting reserve, reaching-neutral in banked race evidence, the club-keelboat tier that fills Lac Léman, Lake Zürich and Lake Constance racing. SPARKFLEX follows in second at 21.9% (42 boats), the minimal-scale, upright-riding platform on a tender righting reserve — the one-design and sportboat keelboats Swiss owners pick for short flat-water courses. HEFTLINE rounds the top three at 14.1% (27 boats), the compact, level-riding platform on a stiff righting reserve, the modern compact-racer profile. LEANFORCE is fourth at 13.5% (26 boats), a compact-scale grouping. Together the top three account for about three-fifths of the hulls — an Alpine-lake signature read directly off the boats Swiss owners choose, with the grand-prix tier living alongside it. In 2025 KAJSA III (DK 46) won Class A at the 43rd Copa del Rey — Switzerland's only European championship class title of the season, carried back to the lakes from Palma.

  • KEELRUN 25.0% · 48 boats
  • SPARKFLEX 21.9% · 42 boats
  • HEFTLINE 14.1% · 27 boats

Dimension emphasis: Hull Efficiency · Comparative Time · Crew Intelligence

Felci U leads the drawing board — Felci's Italian-school lake-and-Mediterranean range the most-represented design voice in the fleet. In 2026 the Swiss forward path runs lake championship first and KAJSA III's Copa del Rey Class A defense second — a KEELRUN-led national fleet on Lac Léman, Zürich and Constance, with the European championship signature carried into the Mediterranean when the lakes release.

What we saw

A KEELRUN-led fleet read — and a Palma race group that did not match it.

Switzerland's 192-boat fleet is led by KEELRUN — a quarter of the hulls — the compact upright-riding platform ahead of SPARKFLEX and HEFTLINE in a broad Alpine-lake-first top tier. Two Swiss boats raced the 43rd Copa del Rey ORC European Championship 2025 on Palma Bay against a 117-entry international field, and KAJSA III came home with Class A — the country's only European championship class title of the season, carried back to Lake Constance on a Mills-designed DK 46. Four insights from the Swiss lake-racing fleet and a Mediterranean grand-prix week that did not match its home-water bias.

Pre-race window · Archetype-Conditions

KEELRUN and the lake thermal — the breeze band the Swiss fleet is built around.

The 2026 Swiss season opens on Lake Geneva, Lake Zürich and Lake Constance with the club championship circuit and the ESSE 850 one-design fleet, and runs through the summer toward KAJSA III's Copa del Rey Class A defense in the Mediterranean. Swiss lake racing is short-course, flat-water racing under thermal breezes that build and fade through the afternoon — and KEELRUN, the fleet's largest archetype at 25.0% of the hulls, is the platform Swiss owners have picked for exactly that water: compact-scale, upright-riding club keelboats. In banked race evidence the archetype's best-observed window is moderate breeze — the band a settled afternoon thermal delivers — so on the days when the pressure fills in over flat water, the fleet's biggest archetype is racing where its record is strongest. Pre-race context — the day's actual pressure and crew execution will arbitrate.

Championship Citation

KAJSA III — European Champion, Class A.

KAJSA III (SUI-2012, DK 46, AEROSTREAM) finished 1st of 34 in Class A with 25.5 points at the 43rd Copa del Rey ORC European Championship 2025 — the country's only European championship class title of the regatta. A Mills-designed DK 46 in a 117-entry international field, converting a 40-race, four-class championship week on the Palma breeze into the Class A trophy and holding off the German runner-up (GER-8042) and the Spanish third (ESP-19981). In the current fleet view KAJSA III sits in the AEROSTREAM archetype — the towering-scale grand-prix platform with a level posture on a stiff righting reserve, the TP-52 and Farr 40 tier, strong upwind in the banked evidence — a profile with the power to hold a championship week together in the breeze Palma delivered, race after race, through the title stretch.

Multi-Dimension Presence

KAJSA III outsailed the fleet it beat — the numbers behind the title.

The championship was earned on the water, not on the scoresheet alone: across nine scored races KAJSA III ran 12.4 sec/nm faster than the comparison cohort's median on corrected time — 71st percentile of the observed championship fleet — while winning two races and adding three more top-three finishes on the Class A board. Negative is faster here: the corrected-time reading is the gap to the observed cohort's median pace, and the Mills-designed DK 46 carried it with a hull-efficiency index of 0.585 — the certificate physics to go with the standings record. The second Swiss boat completes the picture: MUSICA, the Botin TP 52, ran even faster against the cohort median — 16.0 sec/nm under it, 77th percentile — without converting on the Class A board. One Swiss program took the allowance column, the other took the trophy; both AEROSTREAM platforms sailed clear of the championship median for the week.

  • KAJSA III Comp Time: −12.4 sec/nm vs cohort median · 71st percentile of 113
  • Race record: 2 wins · 5 top-threes of 9 scored · Class A
  • KAJSA III Hull Efficiency: 0.585 · MUSICA Comp Time: −16.0 sec/nm · 77th percentile

Fleet vs Race Composition Shift

The Swiss boats that traveled to Palma were not the Swiss fleet.

Switzerland's 192-boat national fleet runs KEELRUN 25.0% / SPARKFLEX 21.9% / HEFTLINE 14.1% — the KEELRUN-led Alpine-lake-first signature of the full SUI/CHE fleet. The 2 Swiss boats that traveled to the 43rd Copa del Rey were both AEROSTREAM grand-prix platforms (KAJSA III DK 46 and MUSICA TP 52) — a 100% AEROSTREAM traveling group where AEROSTREAM holds just 7.3% of the national fleet. The Palma delegation is not a cross-section of the Swiss fleet; it is a narrow slice of the grand-prix top, the layer where international championship programs live. Neither KEELRUN nor SPARKFLEX — the two largest archetypes in the national fleet — was represented at Palma, because that tier lives on the lakes, and the grand-prix tier travels. When the European championship result comes home, read it as a grand-prix result from a championship program, not a signature of Swiss lake racing as a whole.
