Viking River Cruise Line are now officially in the Guinness book of records as they made history on Wednesday by being the first river line to have the fastest growing fleet in history by organising a  naming ceremony held in Amsterdam with 8 ships in total being Inaugurated by one company. Actually, in total, 10 ships were officially welcomed into the Norse-themed fleet (it was a delayed naming for two of them, which debuted last summer, and Guinness did not include them in its calculations). The all-identical, 190-passenger ships are part of Viking’s innovative Longships series, which saw six new vessels introduced in 2012. These, along with today’s 10 and next year’s planned 12 ships, contribute to the cruise line’s stature as the industry leader in the dynamic river cruising niche. It’s what Hagen, who created the company in 1997, describes as “phenomenal growth. We build as many ships in one year as our competitors have in total!”
