Analysis

After the acft departed the seaplane parking area, the plt noticed that the left float was taking on water. He initiated a turn back towards the ramp area & applied full power in an attempt to reach shallower water. As he apchd the parking area & was turning the acft out of the wind, a combination of wind, wave action & forward motion caused the left float to dig in. The acft then nosed over in about 4 ft of water. A post-crash exam of the left float revealed a 1-1/2 inch transverse split just forward of the bulkhead in the largest compartment of the float which allowed it to take on water.
