On 20 May 2017 during the christening of the ship Sólberg ÓF 1 in Iceland, a bottle of champagne turned out to be very difficult to break. Before embarking on a ship for its first voyage, It is customary to break a bottle of champagne in the hull for good luck. A bottle that does not break, is traditionally a sign of a bad omen. It took 5 attempts to finally break the bottle.
