Why did the ship Vasa sink?

The ship Vasa sank on its maiden voyage in 1628 due to a combination of design flaws and inadequate ballast. The vessel was top-heavy because it had two gun decks and lacked sufficient weight at the bottom to stabilize it. Additionally, strong winds exacerbated the situation, causing the ship to heel over and ultimately capsize just minutes after setting sail. The Vasa's sinking highlighted the importance of proper naval engineering and design considerations in shipbuilding.
