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.

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? Ted, KN1CBR ------------------------------ Message: 23 Date: Sun, 28 Jan 2018 01:30:52 +0000 From: Ted Edwards W3TB <[email protected]> To: "Edward T.

That would usually be too slow to pass enough water by the rudder to maintain steering control. On Sat, Jan 27, 2018 at 17:47 Edward T.
