Aerobic exercise:
Muscular activity which requires oxygen to fully metabolise glucose for energy.
aft
The rear part of a canoe or kayak.
Anaerobic exercise:
Intense muscular activity using energy generated by conversion of glucose to lactic acid, which does not require oxygen. It can be maintained for only a short period of time. Oxygen is required for recovery and further metabolism of the glucose supplying more energy.
Asymmetric blades:
A blade with an unequal curved end. Shaped to give a smooth and efficient entry to the water.
Approach angle:
The angle at which you set the boat when about to enter the current. For example when ferry gliding and breaking in and out of the current.
Back paddle: (Should always be refered to as Reverse Paddling!)
Paddling backwards will move the boat in a reverse direction. It will also stop or slow the boat when in a forward motion.
Bailer:
Anything used to bail water out of a boat.
Bank support (team):

Rotating the upper body whilst paddling. Using body rotation ensures that the powerful back muscles are used and strain is reduced on the arm muscles.
Boof
Boofing is a whitewater paddling maneuver for going over drops whereby the paddler jumps over water hazards known as holes at the bottom. When you do this properly, there is a distinct "boof "sound. See "Boof"
Booties:
Footwear made of neoprene. Usually used by snorkel/scuba divers and commonly used by canoeists.

A paddle stroke applied towards the front of a canoe or kayak. By using a combination of a bow rudder and draw stroke, the bow of the boat is turned very effectively sideways and around the blade performing the stroke.
Bow rudder:
A paddle stroke applied towards the front of a canoe or kayak. By holding the blade still in one position the momentum of the boat will assist the bow to veer sideways around the blade performing the stroke. It is a very effective way of turning the boat.
Bow seat:

Buoyancy:
Flotation materials fitted inside a craft or onto a person to keep the craft or person afloat. What, in a sea kayak, there is never enough of. (When the compartments of a sea kayak are not filled with gear they should be filled with buoyancy material.)

Compartment
The space separated from the rest of a boat by a bulkhead (e.g. in a sea kayak) for the stowage of gear and preservation of buoyancy. cotton A useful natural fibre.

The section of river that is between you and the start of the river. The side of the boat facing the oncoming current. 
Upstream V:
A V shaped wave pattern formed by water moving past a rock which is just below the water surface.
Wake:
The temporary trail in the water behind the canoe; also called the wash. If another boat rides on the wash, the paddler can go the same speed but with less effort exerted.
Wave:
A rise in flowing water in the shape of a pinnacle or hump, caused by the power and varying forces of the river as it accelerates or changes direction.
"Weather Cock"
A boats tendancy to turn into the wind
Weils Disease r Leptospirosis is a bacterial infection carried in rat’s urine which may contaminate water in lakes, rivers, etc
Weir A wall across a river to control its flow, such as the ‘locks’ on the Murray. They are dangerous, because the flow at the surface immediately downstream of the weir will be upstream — objects (i.e. boats and people) can be trapped in the circulating flow. Keep well away from weirs, both upstream and downstream.
Wetsuit:
A garment made of neoprene foam which insulates against the chill of cold water; essential for cold water canoeing to avoid hypothermia.
White water (wild water):
Fast moving turbulent water.
Wild water race:
A race held on white water, with rapids being grade 3 or over. Wild water races are usually 3 8km long. 
Wing paddle
 A type of racing paddle with an aerofoil like cross section.
X rescue:
A deep water rescue which is performed by one paddler. The rescuer drags the victim's upturned boat across his/her own boat and empties it by see sawing it and then places it on the opposite side. Very similar to a T Rescue where the boat is brought up onto the rescuers cockpit and emptied and then returned to the SAME side.
