Released via Asia Catamarans’ official news channel, Stealth Mode showcases their commitment to innovative design and advanced materials.

The new model builds upon a proven formula: vacuum-infused epoxy construction, carbon reinforcements in high-load areas, and minimalist interiors to reduce weight—all characteristic of the Stealth line.

The Stealth Lineup: A Brief Overview

Asia Catamarans champions several standout models in its performance‑cruising Stealth range:

  • Stealth 12.2 S: A nimble coastal cruiser with twin heads/showers and a displacement around 3,200 kg—perfect for regattas and weekend stays.
  • Stealth 13 S: A lightweight racer-cruiser (stay weight ~3,545 kg) featuring all-carbon construction, twin helms, and titanium accents—epitomized by “Bliss 2”
  • Stealth 13.2: Designed for blue‑water passages, this model sleeps nine and has two heads/showers, A bridgedeck clearance of 800 mm, and a functional layout featuring an aft-facing galley and forward nav station.
  • Stealth 14 GT: A more spacious cruiser exemplified by “Wow,” which is completing a circumnavigation.

These models are good examples of the brand’s formula: light epoxy hulls, the use of carbon, and a race‑focused mindset with all the facilities needed for cruising.

Origins: A Swiss‑Australian Partnership

Asia Catamarans began life in 2000 as “Composite Yacht Constructions,” founded by Swiss carpenter and sailor Roger Diggelmann. Fluent in Thai, he crafted high-quality composite yachts and trained local craftsmen. A decade later, Australian naval architect and sailor Alan Carwardine had independently designed and begun building the Stealth concept. Their chance meeting halfway through building his prototype Sidewinder led to a 50/50 partnership that launched Asia Catamarans.

Carwardine’s lightweight performance concepts were unique in Southeast Asia and quickly gained fame on the racing circuits for their speed and agility. The timing was ideal to pair his design expertise with Roger’s proven shipyard capabilities.

Craftsmanship & Production

Located just south of Phuket Town in Chalong Bay, Asia Catamarans operates aproduction yard producing 3–4 Stealth boats annually. Their construction methods include vacuum‑bagged PVC foam/glass panels, epoxy infusion, and carbon reinforcement in high-load zones such as beams, rudders, and masts—ensuring light and durable yachts.

There are already over 30 Stealth catamarans in operation globally, and their growing fleet includes electric and power variants—such as the Stealth E40 electric catamaran and the Stealth 36e power cat with top speeds near 25 knots.

Notable Builds in the Fleet

  • “Bliss 2” (Stealth 13 S): Fully carbon, twin helms, 17 m mast—all on a 3,545 kg frame—embodies racing-pure design with cruising comfort.
  • “F1” (Stealth 42 ft power cat): Launched December 2024, this charter-ready vessel mixes speed (25 knots via twin outboards) with spacious living zones for up to 25 guests.
  • “Wow” (Stealth 14 GT): Underway on a global circumnavigation, a testament to the range’s blue-water capabilities

What sets Stealth apart?

Asia Catamarans stands out in the catamaran market for several reasons:

  1. Lightweight engineering – Vacuum infusions, epoxy and carbon build techniques yield displacement below comparable European models.
  2. Seamless race/cruise crossover – Whether angled towards regatta performance or long-haul comfort, these yachts are customisable, from daggerboards and performance rigs to air-conditioned interiors.
  3. Regional design – Purpose-built for tropical conditions, with features like high bridgedecks, superior ventilation, and composite finishes tuned to Asian climates.
  4. Hybrid-power alterantives– Their electric E40 and efficient power boats show a readiness to blend sustainability with performance .

The Future: What’s Ahead?

With Stealth Mode newly launched and development of all-carbon, hybrid-electric models like the E40 underway, Asia Catamarans is accelerating. They’re already filling orders through 2025, growing their team, and setting new production targets—while maintaining their base in Phuket .

Their next-generation lineup may include larger all-electric platforms, refined composite advancements, and perhaps an all-carbon flagship.

Conclusion

Asia Catamarans has evolved from a regional builder into a recognised maker of performance catamarans—thanks to Roger Diggelmann’s precision craftsmanship and Alan Carwardine’s marine engineering skills. With over two decades of innovation under their belt, including custom sailing and power Stealth lines, electric pioneers, and blue-water credentials, the new Stealth Mode continues a legacy of high-speed capability, sleek design, and seaworthy builds—made in Phuket—but raced and chartered around the globe.

As Stealth Mode hits the water, the market is watching closely.
