Asia Catamarans


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 2011, 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 catamaran design ‘Stealth. 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 partnership & the rest is history.

Some of the boats built to date:

Noah Thompson 39ft dive boat
All 3 Andaman Cabriolets 39ft sailing catamarans
