Narrative:
I landed in tenekee, ak, which at the time was very doable for a C206. After off loading freight I taxied out with 2 passenger onboard for a flight to hanus bay. After taxiing out to find calmer water to depart I located an area which was protected from the waves which were coming in from the southwest. It's important to note that at this time the water was still adequate for departure. I applied power for takeoff for about 10 seconds after which I realized the water conditions had gotten much worse. I began to taxi back to the float dock, and as I was doing so the waves kept washing up and over the left float. The water was slowly filling the float compartments as some of the float balls had come loose. After realizing I couldn't make it back to the dock, I shut off the engine and pointed the aircraft into the wind to try to sail the plane back to shore which was then about 50 ft behind me. About a min later the left float and wing started to submerge under the water. The 2 passenger and I got out of the right side and on to the right float. A boat picked us up within 3 mins. This incident happened after my decision was made to return to the dock for better conditions.

Title: PLT OF AN ATX C206, AMPHIBIOUS FLOAT PLANE, LOST CTL OF THE ACFT WHILE TAXIING BACK TO THE DOCK DUE TO WATER FILLING THE L FLOAT WITH WATER AFTER AN ABORTED TKOF. CAUSED THE L SIDE TO SINK WITH THE L WING IN THE WATER. THE PLT AND 2 PAX EVACED THE STRANDED ACFT AND WERE RESCUED BY A BOAT. THERE WERE NO INJURIES.
