A PADDLER'S GLOSSARY
The area roughly in the center of the canoe lengthwise.
To scout a rapid from the banks of the river. Requires getting out of your craft.
To scout a rapid from your boat. Does not equires getting out of your craft.
The width of a canoe or kayak measured at the widest point.
A canoe paddle with a bend in the shaft, usually at its throat. Increases efficiency (power), with varying compromise in control.
The wide, flat area of a paddle, used for propulsion.
Swirly or unpredictable currents pushing (boiling) to the surface. Usually caused by currents rebounding off the river bed, pushing the water to the surface.
A shallow rapid requiring a lot of maneuvering because of numerous obstacles, usually rocks.
A technique used to drive your kayak for a mini-launch over a shallow ledge or rock. This move can help propel your kayak over the hole formed at the bottom of the drop. (Oddly enough, it is also the name of Michael J. Fox's girlfriend in the 80s movie "Teen Wolf".)
Often used in whitewater kayaking or canoeing. Forward, Back, Draw, Cross-bow draw.
Front of the canoe or kayak.
A paddling technique used to stabilize a tipping kayak by using downward and sweeping strokes while incorporating the hip-snap.
A large wave, usually at the bottom of a drop, with a crest that builds up enough to break back on its upstream slope. This can create a surfing wave.
Occurs when a boat becomes caught sideways in the current against an obstruction. A broach can result in severe damage as the current's force warps the boat around the obstruction. Rescue may be necessary; common site at Six Mile Falls.
Sealed compartment fore or aft in a decked canoe or kayak. Primarily required for flotation but also used as storage area.
An open craft with pointed ends that is propelled with a single-bladed paddle. Also called an "open boat."
This is a general term for accidents on the river, among other places!
A decked canoe. A C-1 is a one person canoe and a C-2 is a two person canoe.
Cubic Feet Per Second. A standard measurement of velocity of water flow at a given point in a river. A gauge measures the number of cubic feet of water passing a specific point over a one second period. The CFS will vary according to water levels and the gradient of the riverbed.
The edge of the kayak; the transition area between the hull and the deck.
International standard classification system for rating the difficulty of fast-moving water:
Class I: Easy. Waves small, passages clear; no serious obstacles.
Class II: Moderate. Rapids of moderate difficulty with passages clear.
Class III: Difficult. Waves numerous, high, irregular. Rocks, eddies, rapids with passages clear (though narrow), requiring expertise in maneuvering.
Class IV: Very Difficult. Long rapids, waves powerful, irregular; dangerous rocks, boiling eddies, powerful and precise maneuvering required.
Class V: Extremely Difficult. Long and violent rapids, following each other almost without interruption; riverbed extremely obstructed, big drops, violent currents, very steep gradient.
Class VI: Unrunnable. Portage the area altogether and live to paddle another day.
The opening in the deck of a kayak or closed canoe where the paddler sits. The curved lip around its edge, used to secure a spray skirt, is the coaming.
Where two or more forks of a river, (or two separate rivers) flow into each other.
This is your "fixed" hand, left or right, depending on personal preference and paddle type. “Lefty” paddles are scarce. Your control hand will stay in the same position on the paddle at all times. See Swivel-Hand.
A type of wave that curls at the top, creating a "tube".
Water that piles up on the upstream side of an obstruction in current.
Closed-in area over the bow and/or stern of a canoe or kayak. Sheds water and, on a canoe, adds strength to the gunwales.
Vertical measurement from the hull's lowest point to its highest, usually from the top of the gunwale amidships to the floor of the canoe.
Waves that are angled diagonally in the river. Usually happen at high water. If not run correctly, these types of waves will flip rafts.
Used to describe tendency of a boat to hold its course.
Used to move the boat sideways. Performed by placing the paddle into the water parallel to the boat at an arm's reach away, then pulling boat over to it.
A short, steep rapid or section of a rapid. Named for the abrupt increase in gradient between the top and bottom of the rapid.
An eddy is a place in a river where the water is moving in a different direction or different speed than the main current. Eddies are formed by rocks in the river, outcroppings along the side, behind logs, bridge pilings, and also on the inside of bends. Eddies are places where kayakers can sit and stay relatively still instead of floating downstream. Eddies come in handy for scouting, resting, etc.
Also known as an "Eddy Wall". It usually develops at high water. The eddies become elevated or depressed relative to the main current. The result is a turbulent wall that divides the eddy current from the main current. The eddies themselves sometimes become boiling whirlpools.
To run a rapid incrementally, in stages, by catching the eddies as you go down. For some rapids, it is a good way to scout.
Term used to describe entering an eddy from the main current.
An eddy line is the part of the river that separates an eddy from the main current. Eddy lines can range from gentle changes of current, to violent, whirlpool-forming obstacles. The speed, volume, and gradient of the current influence the type of eddy line that is formed.
Usually a maneuver performed by burying a boat's bow down and deep under water while the stern pops up. This results in a vertical position (sometimes over-vertical).
A kayak paddle in which the blades are set at an angle to each other in order to present the edge rather than the surface to the wind.
A maneuver used to cross a current with little or no downstream travel. Utilizes the current to move boat laterally.
Also called "secondary stability." Describes a boat's resistance to tipping once the boat has been leaned to a point beyond its "initial stability."
Term used to describe a hull cross section that grows wider as it rises from the waterline toward the gunwales.
Typically located in the stern of the kayak, float bags are simply bags filled with air to help increase buoyancy.
Feet Per Mile – the measurement of a river gradient determined by how many feet the river drops in one mile.
The vertical distance measured from a boat's waterline to the lowest part of its gunwale.
Short rope or grab-handle threaded through bow/stern stems of a kayak or canoe.
Refers to the steepness of a riverbed over a specified distance, usually per mile.
See Class I - VI.

The back end of a boat.
Includes forward, back, sweep, reverse sweep, draw and J strokes.
A hole or breaking wave that stops your downstream momentum.
Extremely dangerous obstacles that clog the current with tree branches or other debris, but still allow the water to flow through. This can trap paddlers and gear and make rescue very difficult.
To fill the boat with water. Usually makes the boat difficult or even impossible to maneuver. The use of air bags to displace water can reduce or prevent swamping.
The last boat down a stretch of the river. Safety measures to make sure no boats are left behind. Sweep boats should be outfitted with a rescue kit.
Used to turn the boat to the off-side by reaching out and ahead, then "sweeping" in a wide arc fore to aft.
The ending point of a paddling trip; where the boats are finally taken from the water. See Put-In.
