55-meter Project 13800 Launches At Lurssen One of the smallest superyachts Lurssen built since 1995 has been launched in Germany. The 55-meter Project 13800 also known as Project 'Moon Sand' is a 55-meter superyacht. For some builders this is a big vessel, for Lurssen it is just about the smallest they build, at least in 25 years. The design is by Bannenberg & Rowell Below we get a glimpse of this vessel in a photo taken by Klaus Jordan/Lurssen. "We are excited to see 13800 emerge from her shed. The initial concept was influenced by our studies based on the classic yacht "Carinthia VI", designed by Bannenberg Snr, and built by Lürssen in 1973", says Dickie Bannenberg.
