WHEN THE PLANE TOUCHED BACK DOWN ON THE WATER, IT WAS IMMEDIATELY HIT WITH ANOTHER LARGE SWELL. THE PILOT REDUCED POWER AND TAXIED BACK TO THE DOCK. THE AIRPLANE WAS SUBSTANTIALLY DAMAGED DURING THE COLLISION WITH THE WATER. THE PILOT SAID HE COULD NOT AVOID HITTING THE LARGE SWELLS WHICH WERE CAUSED BY A NEARBY PASSING BOAT.
