Most people on the upper decks would try to get as high as possible on the hull (in your example go to starboard) and get away from the rigging. If there were any men in the rigging (working sails, fighting tops, etc.) they might jump, but you have to remember most sailors in the Days of Sail couldn't swim, so it was really a choice between two terrifying options: jump into the sea & drown, or stay with the ship & drown.
Contemporary accounts say the Vasa sank like a brick (modern translation ), but since the water where she sank was only about 105ft deep, some of the upper masts were still above water so survivors clung to them or the floating debris. Out of a crew of 445, 30 men went down with the ship.
