Ice at the landing

Nov. 12 went for a spin to the landing.  The narrows was 50% closed, open through the normal channel with chunks floating around.  We could not go through the channel on the east side of big island, the channel was closed by ice.  On arrival at the landing the ice has formed to aprox 800 feet out from the docks and is at least an inch thick at the open water margin.  Wind sw at 11 knots wasn’t breaking the ice at the landing up.  FYI.
