GMT Composites recently shipped a twelve-legged carbon fiber antenna and instrument arch to Holland Jachtbouw (Zaandam, The Netherlands). This has just been installed on an in-build 140-ft aluminum superyacht, due for launching later this year. Langan Design Associates (Newport, R.I. - USA) turned to GMT for building this structure in carbon composite to reduce the weight of the arch that carries Cassiopeia's wide array of antennae, navigation and communications gear. The use of carbon fiber saved over 1,300 lbs.
