ASIA CATAMARANS, formerly Composite Yacht Constructions, was started in 2000 by Swiss born carpenter & sailor, Roger Diggelmann.  Thai fluent, Roger has trained his team of Thai workers & over the years honed their skills to achieve a high level of finish and structural integrity in boats built for local & overseas markets.

In 2012, he found a business partner in Australian boat designer, builder & sailor, Alan Carwardine, who had designed & built his own ‘Stealth’ performance sports boat & the first of his Stealth catamaran design. Alan was halfway through the build of his 2nd Stealth cat when work commitments brought him to Asia & the need to find a competent boat builder to finish it off. The client/customer turned into a 50/50 partnership & the rest is history.

Some of the boats built to date:

  • Jacques Fioleau’s Contrast 44 world sailing catamaran.
  • Noah Thompson 39ft dive boat
  • All 3 Andaman Cabriolets 39ft sailing catamarans
  • Grainger Barefoot 40 sailing catamaran
  • 16 x Stealth performance cruising sailing catamarans
  • 4 x Stealth power catamarans


Roger and his Thai partner, Pornthip,  Alan & 20 Thai workers, make up the company team. The majority of the Thai team come from the same village in rural Thailand & many are related.

The boat yard is situated 5 kms south of Phuket Town on the way to the boating haven of Chalong Bay a beautiful part of the tourist island, Phuket.
