Fishing Drift Logs: Heading vs Course Over Ground

· Goofish®Rod-More Than Fishing

Boat bow, cleat and water reflections in a layered rust red and ivory photographic cover headed Heading vs Course Over Ground.

The trip note says the boat was going north. Does that mean its bow pointed north, its GPS track moved north or north was the direction of a saved fishing mark?

Those are different fields. For a useful drift-fishing record, keep heading, course over ground and bearing to a destination separate. Add the source, time and reference instead of saving an unexplained direction.

This guide is about interpreting and recording information after or during an appropriately supervised fishing trip. It is not a steering procedure, a route recommendation or a method of calculating current from one display.

Heading describes where the bow points

In the vessel context used here, heading describes the direction the bow is pointing. It does not automatically describe the boat's movement across the ground.

Garmin's heading and COG explanation distinguishes heading from GPS-derived direction of movement. Its display options also distinguish a connected heading sensor from a GPS-based source.

A field or icon that looks like a bow-direction indicator therefore deserves a source check. Do not identify the measurement solely from the arrow's shape or the informal name used aboard.

Course over ground describes movement

Course over ground, commonly abbreviated COG, is the direction of movement over the Earth's surface. A boat can point one way while moving another.

For a simple descriptive example, a bow may face toward a shoreline while the boat moves along it. Writing facing shore and moving along shore preserves two observations that the phrase going sideways leaves ambiguous.

The difference is not automatically a fault. Garmin's chart-data alignment explanation notes that GPS tracking describes movement rather than pointing, including situations where a vessel moves sideways or backward under wind or current influences.

This does not identify which influence dominated your drift. Wind, water movement and vessel operation belong in the context, not in an unsupported diagnosis from the difference alone.

Bearing to a mark is a third direction

A bearing to a destination describes where that destination lies from the current location. It is not automatically the heading or current COG.

Garmin's navigation-field definitions distinguish bearing from a planned course. Although labels and available fields depend on the device, the reference question remains important: direction of what, relative to what?

A saved waypoint can be a useful location record without establishing where the boat currently points or moves. Do not label its bearing as drift direction merely because it appears beside the track.

A screen orientation is not another measurement of the drift

The page layout and displayed symbol can depend on equipment settings and available data. Confirm the field and its source in the actual instrument's instructions.

Garmin's heading-line example offers different source selections. That is a reminder to preserve the selected data source, not an instruction to change another vessel's settings.

Do not infer north, boat heading or a safe casting direction from the top edge of an unidentified screenshot. A cropped image can remove the labels and context that make the view interpretable.

Record the meaning, source and time of each direction. A photograph of the bow is not a GPS movement record.

What to preserve in a drift-fishing log

  • Heading: field label, value, source and stated directional reference where available.
  • COG: field label, value and source, kept separate from heading.
  • Destination information: identify any bearing or planned-course field separately.
  • Time: retain the timestamp and time zone for the observation.
  • Vessel state: note drifting, maneuvering or another operator-described state without assuming engines off means unaffected movement.
  • Fishing observation: record the lure, line angle and presentation as observations rather than current measurements.

Keep the instrument's true or magnetic reference where supplied. Do not compare unlabeled angles or make an improvised correction from memory.

If a field is missing, unavailable or not understood, say so. Do not replace it with the direction of a nearby landmark to make the entry look complete.

Match the timestamp before comparing the directions

A heading copied before the drift and a COG screenshot taken later may describe different moments. A turn, repositioning action or change in movement can occur between them.

Use synchronized records where possible and preserve the original image. For a practical logging workflow, read Fishing Trip Logs: Sync Camera, Sonar & Local Time.

Do not ask the operator to divert attention from vessel control to complete a note. Arrange recording responsibilities beforehand or document the available information afterward with its limits intact.

Keep the fishing setup separate from the movement data

A well-labeled direction does not tell you which jig, rod or drag setting to use. Preserve the actual outfit so later comparisons do not silently combine different presentations.

Jigging rod and lure

The GOOFISH Purple Ares Light 190cm jigging rod currently lists a 60–250g jig range and separate spinning and casting versions. Record the actual version and jig used.

The jig range is not a casting allowance or a depth guarantee. Neither heading nor COG converts it into a universal weight requirement for the next drift.

Reel and controls

The GOOFISH BCS250 saltwater baitcasting reel has separate left- and right-hand retrieve options. Keep that choice in the equipment record rather than treating the model name as a complete setup description.

Record relevant control changes separately. A casting brake and fighting drag serve different functions; neither measures water movement, and tightening drag is not a correction for a confusing direction display.

Main line

For GOOFISH Max-8 braided line, retain the selected option and verified packaging information. The name alone does not establish diameter, strength or spool length.

A different line or lure can change the presentation you observe. Do not assign that change to drift direction without accounting for the equipment change.

These products illustrate separate setup-record fields, not a tested matched outfit. Choose the complete tackle for the intended fishing method and conditions within the model-specific guidance.

Do not turn COG into a current or lure-path measurement

The boat's movement over ground is not a direct measurement of water movement at the jig. Nor does it map the underwater route of the lure.

Record what was visible: the direction of line departure, a change in line angle or the ability to maintain the intended presentation. Leave the cause unresolved when the evidence does not establish it.

Do not change the vessel's heading, propulsion or positioning controls merely to make fishing records agree. Those decisions belong to the responsible operator.

Drift-log FAQ

Can heading and COG have the same value?

Yes. They can agree numerically while still describing different things.

Does sideways movement prove a cross-current?

No. The observation alone does not isolate current from wind and vessel operation.

Is bearing to a waypoint the drift direction?

No. It describes the direction to that destination.

Does an arrow-shaped boat icon prove a heading sensor is connected?

No. Check the actual source and display configuration.

What if I only have one unlabeled direction?

Preserve it as an incomplete record rather than relabeling it as heading, COG or current.

Heading is where the bow points. COG is where the boat moves. A useful fishing log names the field before interpreting the number.
