What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Airman was cleared to taxi for a west departure at the Lake Hood seaplane base. He was then cleared for takeoff behind an airplane that had just lifted off. Before beginning his takeoff the Lake Hood tower changed departure directions to east. The airman stated that he noticed the breeze had changed directions and was out of the southeast and considered requesting to change his departure route, but after seeing the aircraft in front of him lift off without any problems decided to go ahead with a west departure. The airman stated that his aircraft did not get airborne until after he reached gull island, and at that time he felt the airplane side slip toward the island and lose lift. The right float come down on the very edge of gull island, hit the surface and bounced back into the water at which time he aborted the takeoff.
