Columbus S50 Exits Build Shed The Columbus S50 that was under construction at Palumbo Superyachts has been moved outside of its build shed and into the open. You can call it a technical launch but the vessel isn't expected to actually launch just yet. They are preparing the yacht for launching in very early 2021. For the time being, work will continue on the final fitting of the vessel as well as critical testing of the many systems onboard. The design of this all-aluminum yacht is by Luca Dini (inside too).
