Mach 40.5 no. 186 (ex-IBSA): 2023 Class40 champion, acquired in 2025 by Les Déferlantes
The Class 40 Alderan (FRA186) is a Mach 40.5 designed by Sam Manuard and built by JPS Production in La Trinité-sur-Mer, launched in August 2022. It is the second Mach 40.5 to come out of the yard after Crédit Mutuel. The boat raced its first three seasons under the Italian colors of sponsor IBSA, skippered by Alberto Bona, before being purchased in 2025 by Sasha Lanièce for Les Déferlantes Sailing Team.
Hull design: the second generation of Manuard’s scow in Class40
The Mach 40.5 is the fifth iteration of the Mach 40 series (Manuard / JPS), developed after the Mach 40.4’s dominance in the 2018 Route du Rhum. The hull pushes the wide bow inherited from the Mini 6.50 scow toward greater reaching power by fine-tuning longitudinal balance to limit bow-diving under bare poles. Today it is the benchmark platform in Class40, with multiple podium finishes in major races since 2022.
First life: IBSA / Alberto Bona, 2023 Class40 champion
Launched in August 2022, the boat immediately raced the Route du Rhum 2022 under the name IBSA, where Alberto Bona finished 8th in Class40 in 15 days 6 hours 19 minutes. The 2023 season was the boat’s busiest:
- RORC Caribbean 600 2023 — 1st in Class40.
- Les Sables – Horta – Les Sables 2023 — 1st in Class40 with Pablo Santurde del Arco, and Class40 24-hour record at 430.47 nm on the first leg.
- Transat Jacques Vabre 2023 — 3rd in Class40 with Pablo Santurde del Arco.
- 2023 Class40 champion (annual ranking).
The 2024 season continued with a 5th in The Transat CIC, 3rd in the Normandy Channel Race and 7th in the Transat Québec – Saint-Malo, still under the IBSA flag.
2025 takeover: Alderan, Les Déferlantes
The boat switches to the FRA flag in 2025 when Sasha Lanièce acquires it for her Les Déferlantes project — the first fully female offshore racing program structured across two classes (Class40 and Mini 6.50). Title sponsor: Alderan, an independent real-estate portfolio management firm (founded 2015, AMF-licensed), committing roughly 80% of the budget for a planned program of 20 races and 4 transatlantic passages. Early results on the boat:
- Armen Race Uship 2025 — 4th.
- Les Sables – Horta – Les Sables 2025 — 13th overall.
- Transat Café L'Or 2025 — 18th in Class40, double-handed with Sanni Beucke (Olympic 49erFX silver medalist, Ocean Race competitor).
- Preparation for Route du Rhum 2026 in solo configuration.
