I spent an extended time on the bow comparing where I thought the wind was coming from and comparing it to the Windex at the top of the mast. I'm usually about 5 degrees off but there may be a difference at water level.
The mistake I made yesterday was not realizing the wind instruments at the helm were set to true wind.
There is a lot of current here.
While on the bow I pondered how sailing forces me against my will to change my habits. If I don't sleep I do very poorly the next day. There are consequences Out Here(tm) especially in the company of high energy others that are just not present in my day to day life.
