Wind at the time from the NW at about 15 mph.As the helicopter lifted off it departed to the east planing to turn to the south. On lifting it appears to have started spining and the pilot tried to make it back to the heliport but it hit the water before he could.
No life jackets or floats as not required. Pilot is a family friend of the passengers and it seems he had just picked them up for a little sight seeing.
