Denmark Fiskeskippereksamen af 1. grad foundations key terms

The motion of a target measured relative to own ship, useful for assessing the developing approach when the displayed reference frame is understood.

The vessel’s movement relative to the earth, distinct from its speed through the surrounding water mass when current or other effects matter.

A radar monitoring method comparing a suitable fixed target with a planned index reference to observe cross-track relationships during a passage.

An operator-selected chart-depth boundary represented using the available electronic-chart contours, requiring appropriate vessel assumptions rather than guaranteeing all nearby water is safe.

Position information whose source does not merely repeat the same underlying sensor, allowing meaningful cross-checking of an apparent electronic fix.

A prediction of how proposed own-ship changes affect tracked encounters, dependent on target-motion and system assumptions that must still be monitored.

Separate requirements concerning the person’s maritime qualification and the lawful conduct of a particular commercial fishing operation, neither replacing the other.

The applicable duty to retain, record and land covered catch, subject to the actual legally defined exceptions for the particular fishery and conditions.

A status related to actual fishing gear restricting maneuverability, distinct from merely possessing a commercial fishing licence or carrying fishing equipment.

Records linking actual catch, handling, landing and commercial information, maintained with factual observations and the applicable correction and reporting procedure.

The mass of water displaced by the floating vessel in the stated condition, corresponding to its supported total weight rather than cargo capacity alone.

An initial small-angle stability quantity formed from the relevant metacenter and center-of-gravity heights, with applicable corrections and important limits to its interpretation.

A correction representing the stability effect of liquid shifting in a slack tank, based on the actual geometry, density and vessel displacement.

A trawl component generating hydrodynamic spreading force, with its actual design and setup determining performance rather than one universal attack angle.

The line running through the lower purse-seine rings, drawn to close the bottom of the surrounding net beneath the fish school.

A panel, grid or other arrangement that influences retention or escape of fish, requiring the actual approved configuration and fishery-specific legal conditions.

A measuring device indicating towing-line tension, useful for monitoring a change but not sufficient by itself to identify one unique gear fault.

Energy absorbed by ice as it melts, used in a stated heat-balance model without establishing the complete real refrigeration or food-safety requirement.

A loop or curved section of a line whose movement or tightening under load can trap a person and create a severe crushing or dragging hazard.

Digital selective calling used to initiate the appropriate maritime alerting procedure, distinct from the following voice exchange on its designated channel.

A search-and-rescue radar transponder responding to compatible radar interrogation, with its display pattern and practical detection depending on the actual conditions.

An approved arrangement allowing specified survival equipment to deploy as a vessel sinks, dependent on correct installation, maintenance and the actual equipment mechanism.

Deck openings and related fittings allowing shipped water to drain, whose obstruction can retain damaging weight and free surface high on the vessel.

A statistical wave-height measure associated with the highest third of waves, not a guaranteed upper bound on individual waves in a sea state.

Fog formed when sufficiently moist air moves over a colder surface and cools to saturation, reducing visibility despite the absence of local rain.

A collection of forecasts exploring variations in initial conditions or modeling, used to assess uncertainty rather than certify one guaranteed outcome.
