Lure archetype · Jerkbait

Jerkbait (floating)

Long, slender, and weighted toward neutral. This archetype floats: the Tank cannot yet build a stable suspending bait, because its righting moment scales with net buoyancy, which goes to zero exactly at neutral. A real suspending jerkbait is a known gap in the model.

The shape

What is a jerkbait?

A jerkbait is a slender minnow-shaped lure worked with changes of retrieve or rod motion. This Tank version floats; the model tests its steady retrieve, but does not simulate the dart and pause that define a real jerkbait presentation.

The Tank test

What the model actually measures

The grid uses 1 cm cells. The Tank computes displaced water, centre of mass, lip force, tracking stability and wobble at its default retrieve speed. It does not predict a running depth or a catch rate. See the equations and limits.

ABS shell, twelve cells long and two deep, five tungsten slugs low, a single-cell lip on the nose, two hook hangers.

Tank verdict: Swims

Swims. A tight, tail-only wobble at slow tempo — subtle. Finesse territory.

  • Line tie is almost on top of the lip. Very little leverage, so the action will be muted.

Compare with the trout minnow

Both designs run through the same Tank model at its default retrieve speed. These figures describe the block builds shown here, not commercial lures.
