Here’s the Advanced Canoeing Terminology Glossary, adapted for experienced paddlers who are likely involved in whitewater, backcountry tripping, technical paddling, or expedition-level canoeing.
🔧 Advanced Canoe Anatomy & Design
Term
Definition
Asymmetrical Hull
A hull design where the bow and stern differ in shape to optimize speed and tracking (common in performance and tripping canoes).
Tumblehome
The inward curve of the hull above the waterline; improves paddle stroke efficiency and secondary stability.
Flare
Outward curve of the hull above the waterline; increases initial stability and deflects waves.
Chine (Soft/Hard/Multiple)
The angle at which the canoe bottom meets the sides: hard chines allow crisp edge control; soft chines offer smoother transitions. Multiple chines add performance flexibility.
Stem
The very front and back edges of the canoe, where hull sides meet.
Sheer Line
The curve of the gunwales from bow to stern; affects how the canoe handles waves.
Waterline Length
The part of the canoe in contact with the water; influences speed and glide.
Skin Coat
A lightweight resin layer over composite material (like Kevlar), minimizing weight for elite trippers.
Freeboard (Dynamic)
The amount of canoe above water when loaded in motion; critical for dealing with rough conditions.
🏃♂️ Advanced Paddling Techniques
Term
Definition
Cross-Bow Draw
An aggressive offside stroke used for powerful directional changes, especially in whitewater or tight maneuvers.
Duffek Stroke
A hybrid stroke used to initiate or control turns in whitewater by placing the paddle upstream like a rudder.
Reverse Duffek
Used to stop or control the boat when approaching eddies or features backwards.
Carving
Tilting the canoe on edge (engaging the chine) to facilitate tighter, controlled turns.
Edging
Intentionally leaning the boat to shift the center of gravity for stability or steering.
Bracing (High/Low Brace)
Defensive strokes used to prevent capsizing; high brace is more aggressive, low brace is more stable.
Feathering
Rotating the paddle blade angle in the air to reduce wind resistance (important in windy or exposed areas).
Back Ferry
A maneuver that allows the paddler to move laterally across a current while facing downstream.
Front Ferry
Moving diagonally upstream while maintaining a bow angle into the current.
S-Turn
A compound maneuver involving entering and exiting two eddies consecutively, used to navigate technical rapids.
🌊 Whitewater & River Hydrodynamics
Term
Definition
Eddy Turn
The act of entering an eddy from the current by carving the boat across the eddy line.
Peel Out
The maneuver of leaving an eddy and reentering the current with control and angle.
Boil Line
Where upwelling water from turbulence distorts the surface; common below large holes or rocks.
Ledge Drop
A sudden vertical drop over rock ledges; can produce strong hydraulics or holes.
Wave Train
A series of consecutive standing waves; requires boat control and bracing.
Pillow
Water piling up on the upstream side of a rock; often signals a large obstacle underneath.
Sieve
A dangerous feature where water flows through a tight rock gap but solid objects cannot pass—extremely hazardous.
Undercut Rock
A rock with a hollow base eroded by water flow—can trap boats or paddlers.
Sticky Hole / Retentive Hydraulic
A powerful recirculating current that can trap boats and paddlers; demands advanced escape techniques.
Tongue
A V-shaped smooth water path between obstacles—often the safest line through rapids.
🧗 Expedition & Wilderness Terms
Term
Definition
Advanced Portage
A complex portage requiring rope work, lining, or bushwhacking, sometimes with multiple trips.
Lining
Using ropes to guide a canoe through shallow or dangerous water while walking along the bank.
Tracking (Lining Upstream)
Using ropes to maneuver the canoe upstream through calm or slow-moving water.
Bushwhack Portage
An off-trail carry between water bodies in remote or unmarked terrain.
Leapfrogging
A portaging technique where gear is moved in stages to reduce fatigue over long distances.
Whitewater Rescue Techniques
Includes live bait rescues, mechanical advantage rope systems, or tension diagonals.
Canyon Run
A section of river enclosed by steep canyon walls—often committing and requires advanced planning.
Self-Rescue
The ability to recover from a capsize without outside help—essential for solo or remote paddling.
🏷️ Advanced Gear & Safety Equipment
Term
Definition
High-Float PFD
A buoyancy aid with extra lift, critical for whitewater and expedition paddling.
Helmet (Whitewater Rated)
Impact-resistant head protection, often with drainage holes and secure chin straps.
Throw Rope System
An advanced setup for swimmer rescues, including rope bags, carabiners, and webbing.
Breakdown Paddle
A paddle that separates into sections for compact storage; used as a backup.
Floatation Bags
Heavy-duty air bags placed in the bow and stern to increase buoyancy after capsizing.
Dry Suit
A waterproof suit with gaskets at neck, wrists, and ankles; used in cold or glacial waters.
Pin Kit
A set of tools (pulleys, carabiners, prusiks) used to unpin a canoe trapped against rocks.
VHF Radio / Satellite Communicator
Essential for expedition communication in remote regions without cell service.
Hypothermia Kit
Emergency gear (space blanket, dry clothes, fire starter) used for post-capsize recovery in cold climates.
📈 Technical Classifications & Ratings
Term
Definition
Class I–VI
International Scale of River Difficulty: Class I = easy; Class VI = extreme/unrunnable without significant risk.
Gradient
The rate at which a river descends, usually measured in feet per mile—steeper = faster and more technical.
CFS (Cubic Feet per Second)
A measure of river flow volume; critical for evaluating safe paddling conditions.
Gauge Height
Water level as measured at a hydrological station; used to assess river running conditions.
Discharge Curve
A graph that relates river flow (CFS) to gauge height, helping predict changing water conditions.
Line
The chosen path through a rapid or river feature—knowing “the line” is crucial in technical paddling.
Scout
The act of exiting the canoe to evaluate a rapid before paddling it.
Run (a Rapid)
To successfully paddle a rapid or river section.
Portage Grade
A rating system for portage difficulty, usually based on length, terrain, and elevation change.
🧠 Specialized Concepts & Jargon
Term
Definition
Boofing
A whitewater technique used to launch the canoe over drops or holes to avoid being submerged.
Surfing (Standing Wave)
Holding position in a wave using boat control and paddle power; a form of playboating.
Dry Line
An ideal line through rapids that avoids taking on water or hitting major features.
Wet Exit
Controlled exit from a swamped or capsized canoe in moving water, maintaining control of boat and paddle.
Pinned Boat
A canoe stuck against rocks by water pressure—requires special recovery techniques.
Ghost Boating
An uncontrolled, unmanned canoe in the current—potentially dangerous.
High-Siding
Emergency maneuver during a broach where paddlers shift weight to the upstream side to prevent flipping.
Paddler Communication
Hand signals or whistle codes used between team members in loud or rapid conditions.
Group Dynamics
Awareness of team decision-making, leadership, and safety responsibilities in remote or technical settings.
