Analysis

The plt elected to takeoff from a lake that was aprx 1/2 mi long & oriented on an east/west heading. During a x-wind takeoff, the plt had difficulty getting the acft to lift off, but elected to continue the takeoff. The acft finally lifted off, but failed to accelerate sufficiently in ground effect. Subsequently, it mushed into a tundra hill while still flying in ground effect. The plt stated he that was fatigued & was overconfident in both himself & his acft. He stated that he should have waited until the wind was along the axis of the lake and/or he should have repositioned his acft on a bigger lake before hauling the cargo.
