The Vasa set sail and fired a salute. But only after a few minutes of sailing the ship began to heel over. She righted herself slightly - and heeled over again. Water started to gush in through the open gunports. And, to everyones horror and disbelief, the glorious and mighty warship suddenly sank! Of the 150 people on board, 30-50 died in the disaster. When Vasa had been salvaged in 1961, archaeologists found the remains of 25 skeletons."
The reason the ship sank so quickly is simple. In the original design, the king's shipbuilders gave it one deck of guns. King Adolphus insisted on a second deck being added. Nobody dared contradict the king, so it was done. Which, of course, made the ship top-heavy.
What an idiot.
