Depressing night. I think the most ornery bit of ocean I've ever been in - sea utterly confused, big, maybe 4 metre wind waves over big SW swells breaking from all sides, current setting north - north!- it even confused the instruments to the extent that the only way to set the boat up was the old primitive wind on the cheek. It still works!
Scary tho ultimately safe near meeting with big cargo ship during the night. More later.
