Innovative Planet Solar Launched into the Water

23 April 2010

After the official christening of the Turanor Planet Solar the 30m long and 15m wide catamaran was lifted out of the production hall of the HDW ship-yard in Kiel to be launched into the water.

The boat is an extremely light carbon-sandwich-design. 20.6t of carbon fibre, 23t of epoxy resin and curing agent and 11,5t of Airex C70 structural foam in various densities.

Besides material choice, also the laminate schedule was optimized for lightest weight. The centre hull shell for instance consists of a sandwich of 4mm carbon skins (double bias and unidirectional) and 50mm C70.130 high density core material. Such skin/core thickness ratios combined with high strength and stiffness core material - capable of absorbing the high loads - are the essence of extreme light weight design.

What distinguishes the Turanor Planet Solar from other high performance boats can be seen from the bird’s eye view: The deck is covered with photo-voltaic panels – 825 panels by the time all panels will be installed with a sur-face of 536,65sqm and 93,5kW at 18,8% efficiency. The sub-construction for the solar panels is a sandwich made from Airex C70 as well.

Raphaël Domjan, project leader and skipper and Gérard d’Aboville, adventurer and also skipper on board will now do first test sailings before the Turanor Planet Solar will start to circumnavigate the world powered only by the sun. The journey will take about 160days with 50,000km to be navigated.
