3Y0Z Bouvet Island DXpedition

Edward A. Dauer
   
I am a pilot rather than a sailor, but I wonder if the two knots means net speed with respect to position, which could mean almost any speed with respect to the flow of water past the hull.  Like the difference between air speed and ground speed?  An airplane with an airspeed of 100 knots into a direct headwind of 98 knots - God forbid - would have a ground speed of two.

Or don't sailors talk that way?

    2 knots?
    That would usually be too slow to pass enough water by the rudder to
    maintain steering control.

Up and Down, Up and down, Up and down if the seas are really rough could
slow things down a little.  You are no longer going in a direct line like
you would in smooth seas.

Hi Ted, Indeed sailors to talk that way. As with an airplane there are multiple factors at work which affect SOG in a sailboat. The hull speed can be different than SOG.
