Foscat-32 (Folding Solar Catamaran) by Hakan Gürsu
2010 - 2011, Platinum A' Vehicle, Mobility and Transportation Design Award Winner
Hakan Gürsu states that the inspiration for Foscat-32 Folding Solar Catamaran came suddenly.
Hybrid marine technological improvement is one of the best systems that compromise between sun and wind powers by reducing CO2 almost to zero during sailing. The system also contributes to renewable energy by using sailing, as well as, solar power and wind energy in seaworthy manners. Future Transportation is a fascinating compilation of material and energy which explores and defines the way the future is imagined in the present and tries to answer that ever more pressing question of how we move forward. The FOSCAT (folding solar catamaran) is designed at very highest calibre which provides high exhilaration performance and unashamedly fast sailing solutions. The FOSCAT is a new alternative concept cat sail-vessel that consumes no fuel with high energy efficiency. Instead, she uses alternative energies and one of a new alternative symbol of raising awareness about sustainable use of resources on the sea. Sailing should be a recreational activity that has no adverse effect on the environment. By drawing an attention to its dual eco-powered and non-polluting attributes, the FOSCAT increases users’ awareness of environmental problems. She is a new generation cat-boat which encourages increased environmental responsibility that is due to the fact of its secure, stable, eco-friendly and outstanding design capabilities. The unique hull shape of the FOSCAT makes light work of big waves even smoother and smaller. Hence, the FOSCAT is able to put many larger cats in the shade. The hulls incorporate skegs rather than dagger boards, which beaches the cat in safer and simpler waves. In addition, the lightweight folding hulls are easy to handle ashore and require virtually no maintenance. The FOSCAT is one of the first folding cats which can easily be folded on docks and on any sand shore. She can easily reduce the wind profile during docking and well landing the hulls can be easily retracted with folding rudders and mast.
Design Challenges
Hakan Gürsu did not encounter any design challenges while designing the award winning Foscat-32 Folding Solar Catamaran.
Production Technology
Technologically innovative materials and new construction techniques were used to minimize weight and hydrodynamic resistance whilst maximizing performance and durability. These technical requirements were to be incorporated into a new form that allowed freedom of all dynamic parts whilst providing visual appeal and overall quality into a non-stop circumnavigating. She can handle any weather conditions within high capability of sailing flexibility. The hulls are constructed on an effective legendry fiber moulding technique which is one of the long lasting solution for its kind. This technique not only gives an incredible flexibility and resilent, but also provides a dynamic stabilitiy. The hull shell is made from a composite of double layer carbon fiber and epoxy resin. In addition, the hull body is laminated as a carbon-foam core that is to create a carbon symmetric sandwich panel. This method creates a lightweight, stiff and highly durable composite body structure and it is well suited to the required organic forms. The body is finished with an epoxy primer coat. Additionally, she provides ultra-violet resistant coating above the water line. The dual-face of moving solid sail harness combines the two of the most abundant sources of energy in nature: solar and wind power. The use of wind power makes it possible to sail uninterrupted throughout the day and night. Double layer solar cell panels –which can be defined as high performance flexible photo-voltaic panels are placed on both sides of the main sail. The solar cell panels charge the small batteries to power the electric motors (DC 2 x 4 HP) and drive the tubular side propellers. The motors on both sides of the boat are placed in such a way that navigation performance is maximized. The vessel can easily be “u-turned” by using the two DC motors with backward and forward action so as to turn around a point.
