There are actually three sister ships to the Vasa. One of those called the Apple and was discovered a few ago outside Stockholm. They are very similar to Vasa but are built slightly smaller in height and about a foot greater in width. The Apple did have the same large sized cannons in the first deck, which was one of the major fault in the design of Vasa. The other two sister ships had smaller cannons on the first deck in order to avoid this problem.
