CI Exam Terminology
FFI Fly Casting Definitions - 2024 version
| Term | Definition |
|---|---|
| Fly Casting | Using a flexible lever to move and unroll a weighted line to propel an artificial lure. |
| Loop | The shape a fly line assumes as it overtakes the rod tip during a Fly Cast. |
| Fly Leg | The moving section of fly line in a Loop from the fly to the start of the Loop Nose. |
| Rod Leg | The moving or stationary section of fly line in a Loop from the rod tip to the end of the Loop Nose. |
| Loop Nose | The curved section of fly line at the front of the Loop which is the transition between the Fly Leg and the Rod Leg. |
| Straight Fly Leg | A Fly Leg where the line and leader are relatively free from curvature from the Loop Nose to the fly. |
| Convex Fly Leg | A Fly Leg with a dome shaped configuration curving away from the Rod Leg. |
| Concave Fly Leg | A Fly Leg which is not Straight and dips toward the Rod Leg. |
| Trailing Loop | A Loop which has a Fly Leg which crosses the Rod Leg. |
| Underslung Loop | A Loop whose Fly Leg unrolls below its Rod Leg. |
| In-Plane Loop | A Loop whose Fly Leg and Rod Leg are in the same plane. |
| Out-of-Plane Loop | A Loop whose Fly Leg and Rod Leg are in different planes. |
| Translation | A linear change in position of the rod butt. |
| Rotation | An angular change in position of the rod butt. |
| Casting Stroke | Rotation and/or Translation of the rod butt sufficient to cause Loop formation. |
| Stroke Length | The distance moved by the rod butt during the Casting Stroke. |
| Casting Arc | The angle change of the rod butt during the Casting Stroke. |
| Stop | Deceleration of the rod resulting in Loop formation. |
| Rod Plane | The surface traced by the rod during a Fly Cast. |
| Rod Tip Path | The straight or curved path travelled by the rod tip during a Fly Cast. |
| Tracking | The lateral path of the rod tip during the Casting Stroke. |
| Trajectory | The direction travelled by the Loop relative to the horizon. |
| Lift | Moving the rod up to reposition the fly line for the next movement in the Fly Cast. |
| Follow-Through | Moving the rod forward and down after the Delivery Cast. |
| Timing | The moments in time when each casting action transitions into the next. |
| Tempo | The rates of movement within a cast. |
| Pause | The time period between Casting Strokes. |
| 180 Degree Principle (Aerialized Casts) | The intended Rod Tip Path and fly line are closely aligned both laterally and vertically with the target at the start of each Casting Stroke. |
| 180 Degree Principle (Anchored Casts) | The Delivery Cast, D Loop and the Anchor are closely aligned laterally with the target. |
| Drift | Moving the rod tip in the direction of the current cast during the Pause. |
| Drag | Moving the rod tip in the direction of the next cast during the Pause. |
| Creep | Drag which contributes to a casting fault. |
| Up/Down | Moving the rod tip up or down during the Pause. |
| In/Out | Moving the rod tip in (closer to the caster laterally) or out (further away) during the Pause. |
| Aerial/Overhead Cast | After the initial Lift, aerialized forward and back casts are made until the Delivery Cast. |
| False Cast | A forward cast followed by a back cast, both of which remain aerialized.. |
| Overhang | The amount of running/shooting line outside the rod tip during Casting Strokes. |
| Point P | The point where the fly line suspended from the rod tip first touches the water. |
| Anchor | The fly and leader/fly line in contact with the water at the bottom of the D Loop. |
| Anchored Cast | A cast whose back cast Loop passes underneath the rod tip and forms an Anchor and a D Loop. |
| Anchor Position | The location and layout of the Anchor relative to the caster. |
| Skipped Anchor | An Anchor which briefly forms and then prematurely leaves the water while moving away from the target before the Delivery Cast. |
| Blown Anchor | An Anchor which prematurely releases from the water during the Delivery Cast. |
| Connection Point | The line/leader or line/sink tip connection. |
| D Loop | A round shaped back cast Loop between the rod tip and the Anchor of an Anchored Cast. Also used as a generic reference to back cast Loops of any shape in Anchored Casts. |
| Key Position | The hand and arm positions from which the caster begins the Delivery Cast |
| River Left/Left Bank | The left bank of the river when facing downstream. |
| River Right/Right Bank | The right bank of the river when facing downstream. |
| Delivery Cast | The final Casting Stroke of a Fly Cast, which presents the fly. |
| Mends | Manipulating the fly line layout by rod movement after the Stop on a Delivery Cast. o Aerial Mends - mending before the line/leader lands on the water. o Water Mends - mending after the line/leader lands on the water |
| Shooting line | Increasing the amount of fly line outside the rod tip by releasing the line after the Stop. |
| Slipping line | Increasing the amount of fly line outside the rod tip by releasing the line and moving the rod either before or after a Casting Stroke. |
| Straight Line Presentations | Casting Strokes and/or Mends which produce a straight line layout. |
| Slack Line Presentations | Casting Strokes and/or Mends which produce slack line layouts. |
| Curved Presentations | Casting Strokes and/or Mends which produce a curved line layout. |
| Single Haul | Pulling the fly line through the rod guides during either the forward or back Casting Stroke. |
| Double Haul | Pulling the fly line through the rod guides during consecutive Casting Strokes, after returning the line hand towards the rod hand during the Pause. |
| Continuous Tension Cast | A cast where continuous rod movement maintains tension in the fly line. |
| Oval/Gebetsroither/Belgian/Elliptical Cast | A Continuous Tension Cast formed by a relatively horizontal back cast Rod Plane which then transitions without stopping into a more vertical Rod Plane on the forward cast. |
| Roll Cast | An Anchored Cast without a substantial change of direction consisting of a Lift, D Loop Sweep, Circle Up, and Delivery Cast in which the fly does not leave the water until after the Delivery Cast. |
| Circle Up | A circular and upward movement connecting the D Loop Sweep and the Delivery Cast with which the caster moves into the Key Position. |
| Hooking | A fault where downward rod tip movement at the end of the D Loop Swings around and behind the caster. |
| D Loop Sweep | A Casting Stroke which initiates the formation of the back cast loop of an Anchored Cast. |
