X-54 Unveiled By Holterman Yachts A new model has been released by the Holterman yard. She is called the X-54 and in a press release the yard detailed the latest member of the X-line. Latest member because the yard already unveiled the X-105 since March 2020 and at the time they did suggest that two smaller designs were 'in development'. The design of the X-54 is by Bernd Weel Design and showcases a modern and sleek profile. Naval Architecture is by Kitty van der Kamp Design. At around 16.60-meters this puts the vessel at 54.4-feet long with a 4.90-meter (16.17-feet) beam. At this size, the draft is not much more than a meter coming in at 1.25-meters.
