Cast
Gissen is an obsolete nautical expression for the approximate determination of the ship's location by dead reckoning , that is, by adding since the departure point (for. Example, the output port or an observed site) traversed suspected distances (by utilization of Sign , time and compass heading were determined ).
The quality of the casted ship's location or casted cutlery determined in this way is naturally highly dependent on adequate consideration of possible sources of error, in particular on wind and current offset ( drift ), which is often difficult to assess .
The terms cast place and cutlery were officially replaced by the terms Koppelort or Loggeort (which are not completely synonymous) with the introduction of DIN standard 13312 at the latest in 1984 . However, some of them are still used in sailing literature or orally.
In the language used on board, the word Gissen may also have meant the, likewise only approximate, location determination by means of a sextant, but without a chronometer.
