Jan 30: Clear sky, no wind. 1 ecotour 1 pleasure craft. Cut and chopped wood. Worked on finishing toilet install in assist house: drain line, vent pipe.

Jan 31:  Fog horn went off throughout the night. Cloudy in the morning, wind 10-15 knots NE. Moved firewood and measured station fuel and water levels for month end report. 3 ecotour boats, 1 sailboat. The sailboat came around the South side of the main island and passed through the small channel between the South Islands, it came very close to the sealions hauled out on the closer South Island.  I called Pedder Bay Marina, gave them the boat’s serial number and asked them to talk to the operator about the 100m marine mammal setback rule.
