The pilot of the seaplane reported that she was enroute to a water landing in the intracoastal waterway. After perfoming a downwind approach to observe the intended landing area the pilot set up for landing. While observing 3 boats in the vacinity, she decided that a safe landing was permissible and proceeded to land. Since one of the boats was heading in the same direction alongside the right shoreline she selected a touchdown Point slightly left of the waterway centerline to avoid the boater's wake. Within seconds of touchdown she felt the aircraft abruptly jar to the left and attempted to apply control corrections to compensate but the aircraft continued to roll over the right float and flipped over into the water. The pilot was able to egress without any reported injury. After egress the pilot climbed onto the belly of the inverted aircraft and saw that a boat was idling nearby. She suspected the boat was there to help so she asked the boat operator if he saw what she had hit and he replied that she hit his boat. The operator of the recreational boat reported that he was traveling near the right shoreline to give way to an oncoming airboat and that after passing decided to steer his vessel toward the deeper water near the center of the waterway. Shortly after veering left his boat spun around violently then came to rest with the engine disabled to the neutral/idle position only. The recreational boat consisted of the operator and one passenger. The individuals aboard the boat reported they were tossed about but had not sustained any serious injury. Substantial damage to the submerged aircraft was determined to be primarily at the right wing, lower engine cowling and the front of the left float. Significant damage to the recreational boat appeared to be at the left side of the outboard motor with loss of forward thrust. The initial points of contact during the collision were between the front of the aircraft's left float and the left side of the boat's outboard motor.
