Princess Yachts 30M "Kohuba" On Sea Trials This yacht was launched earlier in the month and to most of us, only known by her model name, the Princess 30M. It appears that her name is "Kohuba" and the first hull in the new 30M series is already conducting sea trials. Princess Yachts isn't playing around with this one as they need to get her ready for her world premiere at the Dusseldorf Boat Show in Germany in January next year. The show itself is going to be running from January 23 to the 31st and if you want to glimpse the new Kohuba she'll be on display. Princess Yachts stand is set to be stand 6B21.
