Superyacht Siran
The Bannenberg designed Siran was built by Feadship Royal De Vries in 1991. At the time of her launch she was probably the most luxurious and complex yacht ever built by Feadship, pushing the boundaries of what was thought possible by incorporating huge laminated glass windows, a 40 ton floating stairway in marble onyx, and gold, an aft-winding stairway extending over two decks. She still has her original and extremely luxurious interior, designed by Bannenberg, which remains one of the best kept secrets in the superyacht industry. The 67 metre yacht was extensively refitted and lengthened at the De Vries Makkum facility in 2005 and 2006.
