A wood-and-canvas canoe evokes the heritage of canoeing in North America.

A canoe is a small narrow boat, typically human-powered, though it may also be powered by sails or small electric or gas motors. A boat is a Watercraft of modest size designed to float or plane on water and provide transport over it Canoes usually are pointed at both bow and stern and are normally open on top, but can be covered.

In its human-powered form, the canoe is ordinarily propelled by the use of paddles, with the number of paddlers (most commonly two) dependent on the size of the canoe. A paddle is a tool used for pushing against Liquids either as a form of propulsion in a Boat or as an implement for mixing Paddlers face in the direction of travel, either seated on supports in the hull, or kneeling directly upon the hull. A hull is the body of a Ship or Boat. It is a central concept in floating vessels as it provides the Buoyancy that keeps the vessel from sinking Paddling can be contrasted with rowing, where the rowers face away from the direction of travel (though a wide canoe can be fitted with oarlocks and rowed). With regard to Watercraft, rowing is the act of propelling a boat using the motion of Oars in the water A rowlock (British or oarlock (US is a Brace that attaches an Oar to a boat. Paddles may be single-bladed or double-bladed. A paddle is a tool used for pushing against Liquids either as a form of propulsion in a Boat or as an implement for mixing

The oldest recovered canoe in the world is the canoe of Pesse. According to C14 dating analysis it has been constructed somewhere between 8200 and 7600 B. C. This canoe is exhibited in the Drents Museum in Assen, Netherlands. Assen ( is a Municipality and a City in the north eastern Netherlands, capital of the Province of Drenthe.

Sailing canoes (see Canoe Sailing) are propelled by means of a variety of sailing rigs. Canoe sailing refers to the practice of fitting a Polynesian Outrigger or a Western Canoe with Sails See also Log canoe, a type Common classes of modern sailing canoes include the 5 m² and the International 10 m² Sailing canoes. The latter is otherwise known as the International Canoe, and is one of the fastest and oldest competitively sailed boat classes in the western world. The log canoe of the Chesapeake Bay is in the modern sense not a canoe at all, though it evolved through the enlargement of dugout canoes. The log canoe is a type of Sailboat developed in the Chesapeake Bay region The Chesapeake Bay is the largest Estuary in the United States. A dugout is a Boat which is basically a hollowed tree trunk Other names for this type of boat are logboat and monoxylon.

  1. Bow
  2. Stern
  3. Hull
  4. Seat (whitewater canoes may have a foam 'saddle' in place of a seat)
  5. Thwart - a horizontal crossbeam near the top of the hull
  6. Gunwale (pronounced gunnel) - the top edge of the hull
  7. Deck (under which a flotation compartment or foam block may be located which prevent the canoe from sinking if capsized or swamped)

Optional features in modern canoes (not shown in diagram):

  1. Yoke - a thwart across the center of the boat to allow one person to carry the canoe, sometimes molded to the shape of the shoulders. The bow (pronounced &mdashrhymes with how) is a nautical term that refers to the forward part of the hull of a Ship or Boat, The stern is the rear or aft part of a Ship or Boat, technically defined as the area built up over the Sternpost, extending upwards from the Counter A hull is the body of a Ship or Boat. It is a central concept in floating vessels as it provides the Buoyancy that keeps the vessel from sinking The gunwale (ˈɡʌnəl "gunnel" to rhyme with "tunnel" is a nautical term describing the top edge of the side of a Boat. The most general definition of foam is a substance that is formed by trapping many gas Bubbles in a Liquid or Solid. A yoke is a wooden beam which is used between a pair of Oxen to allow them to pull a load (oxen almost always work in pairs
  2. Keel - a structural element that runs along the bottom of the canoe's hull, from the bow to the stern, serving as the foundation or spine of its structure and, depending on its depth, providing some directional control and stability. In boats and ships keel can refer to either of two parts a structural element or a hydrodynamic element
  3. Flotation bags - inflatable air bags to prevent swamping the canoe in rapids
  4. Spraydeck - a cover to prevent water entering the canoe

The portion of the hull between the waterline and the top of the gunwale is called the freeboard. A spraydeck (or spraycover or sprayskirt) is a flexible cover for a Boat, in particular for a Kayak or a Canoe.

The earliest canoes were made from natural materials:

Modern technology has expanded the range of materials available for canoe construction.

Depending on the intended use of a canoe, the various kinds have different advantages. For example, a wood-and-canvas canoe is more fragile than an aluminum canoe, and thus less suitable for use in rough water; but it is much quieter — thus better for observing wildlife. However, canoes made of natural materials require regular maintenance without which they lack durability. A Kevlar canoe is tough and also light, good for wilderness tripping. Modern hybrids can combine the elegance and style of traditional wooden canoes with such benefits as modern materials can provide.

Shape

Many canoes are symmetrical about the centerline, meaning their shape can be mirrored along the center. When trimmed level (rarely the case) they should handle the same whether paddling forward or backward. Many modern designs are asymmetrical, usually having the widest beam slightly farther aft which improves efficiency and promotes more level fore and aft trim. A further improvement may be found in canoes with a straighter hull profile aft and rocker forward which improves tracking.

A traditionally shaped canoe, like a voyageur canoe, will have a tall rounded bow and stern. A coureur des bois (runner of the woods was an individual who engaged in the Fur trade without permission from the French authorities Although tall ends tend to catch the wind, they serve the purpose of shedding waves in rough whitewater or ocean travel.

Some canoes are made with squared sterns — "Y", "V", or "U" shaped — in order to permit the mounting of outboard motors. Very large freighter canoes can be powered with powerful motors, but canoes that are 18 feet (5. 5 m) or less in length would normally be propelled by motors of 3 horsepower (2. 2 kW) or less. Side brackets can be mounted on canoes with pointed sterns to mount small outboard motors of about 1½ to 2 horsepower (1. 1–1. 5 kW), which propel such canoes with surprising speed.

Cross section

The shape of the hull's cross section significantly influences the canoe's stability under differing conditions. Flat-bottomed canoes generally have excellent initial stability, which diminishes rapidly with increased heel. Initial stability is the resistance of a Boat to a small amount of lateral tilting from its equilibrium position. Their high initial stability causes them to have a more abrupt motion in waves from the side.

For a given beam, a rounded-bottom canoe will have less initial stability than its flatter bottomed cousin. Round sections have lower surface area for a given volume and have less resistance through the water. They are most often associated with racing canoes.

In between the flat and rounded bottom are the more common shallow-arc and "V" bottom canoes which provide a compromise between performance and stability. The shallow-vee bottom, where the hull centerline forms a ridge like a shallow "V", will behave similar to a shallow-arc bottom but its volume to surface ratio is worse.

Similar is the tumblehome hull which has the top portion of the hull curving back in slightly.

Many modern canoes combine a variety of cross sections to suit the canoe's purpose.

Keels

Keels on canoes improve directional stability (the ability to 'track' in a straight line) but decrease the ability to turn quickly. Consequently, they are better suited for lake travel, especially when traveling on open water with crosswinds. Conversely, keels and "Vee"-bottoms are undesirable for whitewater because often quick turns are required. Whitewater is formed in a Rapid, when a River 's gradient drops enough to disturb its Laminar flow and create Turbulence, i

In aluminum canoes, small keels occur as manufacturing artifacts when the two halves of the hull are joined. In wood-and-canvas canoes, keels are rub-strips to protect the boat from rocks and as they are pulled up on shore. Plastic canoes feature keels to stiffen the hull and allow internal tubular framing to lie flush with the sole of the canoe.

Rocker

Curvature of the hull profile that rises up at the bow and stern is called "rocker". Increasing the rocker improves maneuverability at the expense of tracking. Specialized canoes for whitewater play have an extreme rocker and therefore allow quick turns and tricks. Rocker also has an immense effect on the stability of a Canadian canoe. By lifting the ends of the craft out of the water, rocker puts more of the wider center section of the boat into the water, contributing significantly to the overall stability of the craft. 35 mm rocker at each end makes all the difference to how safe a novice will feel in a canoe.

Gunwales

Modern cedar-strip canoes have gunwales which consist of an inner and outer parts called "inwales" and "outwales". These two parts of the gunwale give rigidity and strength to the hull. The inwale will often have "scuppers" or slots cut into the inwale to allow water to drain when the canoe hull is turned upside down for storing.

Types of canoes

In the past, people around the world have built very different kinds of canoes, ranging from simple dugouts to large outrigger varieties. A dugout is a Boat which is basically a hollowed tree trunk Other names for this type of boat are logboat and monoxylon. The outrigger canoe ( Tagalog and Indonesian: bangka; Maori: waka ama; Hawaiian: waʻa; Tahitian: More recently, technologically advanced designs have emerged for particular sports.

Traditional designs

Early canoes have always incorporated the natural materials available to the local people. The different canoes (or canoe like) in many parts of the world were:


Dugout
Formed of hollowed logs; may have outriggers in some cultures. A dugout is a Boat which is basically a hollowed tree trunk Other names for this type of boat are logboat and monoxylon. On the west coast of North America, large dugout canoes were used in the Pacific Ocean, even for whaling.

Birch-bark canoe
In the temperate regions of eastern North America, canoes were traditionally made of a wooden frame covered with bark of a birch tree, pitched to make it waterproof. Birch bark or birchbark is generally understood to be the Bark of the Paper Birch tree ( Betula papyrifera) or sometimes of related species such Pitch is the name for any of a number of highly viscous Liquids which appear Solid.

Voyageur canoe
Traditional voyageur canoes were similar to birch-bark canoes but larger and purpose built for the fur trade business, capable of carrying 12 to 20 passengers and 1,400 kilograms (3,100 lb) of cargo. The fur trade is a worldwide industry dealing in the acquisition and sale of animal Fur.

Wood-and-canvas canoe
The wood-and-canvas canoe evolved in Maine in the late 19th century from the birchbark canoe when canvas became much easier to acquire than the bark of the white birch tree. The canoe shown here was built by the late well-known craftsman, Joe Seliga, of Ely, Minnesota. Joe Seliga ( 11 April 1911 &ndash 18 December 2005) was a master builder of wood-and-canvas Canoes in Ely Minnesota.

Modern designs

Modern canoe types are usually categorized by the intended use. Many modern canoe designs are hybrids (a combination of two or more designs, meant for multiple uses). The purpose of the canoe will also often determine the materials used. Most canoes are designed for either one person (solo) or two persons (tandem), but some are designed for more than two persons.


Touring canoe
Also known as tripping canoe. In North America, a "touring canoe" is a straight tracking boat good for wind blown lakes etc. A "tripping canoe" has a larger capacity for wilderness travel and is designed with more rocker for better maneuverability on whitewater rivers but requiring some skill on the part of the canoeist in open windy waters, when lightly loaded. Often made of lighter materials and built for comfort and cargo space; usually a more traditional design.

Prospector canoe
A generic name for copies of the famed Chestnut model, a popular type of tripping canoe marked by a symmetrical hull and a relatively large amount of rocker; giving a nice balance for wilderness tripping, of the ability to carry large amounts of gear whilst being maneuverable enough for whitewater. This makes it a superb large capacity wilderness boat, but requires skill on windy, broad waters when lightly loaded. Made in a variety of materials. For home construction, 4mm plywood is commonly used, mainly marine ply, using the "stitch and glue" technique. Commercially built canoes are commonly built of fibreglass, HDPE, Kevlar, Carbon Fiber, and Royalex which is although relatively heavy, very durable.
Long Distance Touring canoe A cockpit has many advantages: the gunwale can be made lower and narrower so the paddler can reach the water more easily, and the rim of the boat can be higher keeping the boat dryer. With a rounded hull shape and full ends there is less for turbulent water to work on.

Whitewater canoe
Also known as river canoe - typically made of tough man-made materials, such as ABS or Kevlar, for strength; no keel and increased rocker for maneuverability; often extra internal lashing points are present to secure flotation bags, harness, and spraydeck. Some canoes are decked and look very much like a kayak, but are still paddled with the paddler in a kneeling position and with a single bladed paddle.
Playboating open canoe A subgroup of whitewater canoes specialized for whitewater play and tricks or for competitive whitewater slalom. Playboating is a discipline of whitewater Kayaking or Canoeing where the paddler performs various technical moves in one place (a playspot as opposed to downriver Whitewater Slalom is a competitive sport where the aim is to navigate a decked Canoe or Kayak through a course of hanging gates on river rapids Some of these canoes are short in length and have such extreme rocker that they are also known as banana boats.
Square stern canoe An asymmetrical canoe with a squared off stern for the mounting of an outboard motor; meant for lake travel or fishing. An outboard motor is a propulsion system for smaller Boats General uses Outboard motors for a Boat are developed as a self-contained

Racing canoe
Also known as sprint canoe - purpose-built racing canoe for use in racing on flat water. A sprint canoe is a special type of Canoe used in the sport of flatwater canoe racing. This article discusses flatwater racing (sprint and marathon racing, competitive forms of Canoeing and Kayaking on more or less flat water To reduce drag, they are built long and with a narrow beam, which makes them very unstable. In Fluid dynamics, drag (sometimes called fluid resistance) is the force that resists the movement of a Solid object through a Fluid (a The beam of a ship is its width at the widest point or at the mid-point of its length A one-person sprint canoe is 5. 2 meters or 17 feet long. Sprint canoes are paddled kneeling on one knee, and only paddled on one side; in a C-1, the canoeist will have to j-stroke constantly to maintain a straight course. Marathon canoe races use a similar narrow boat.

Inflatable canoe
Similar in construction and materials to other inflatable boats but shaped like a canoe. An inflatable boat is a lightweight boat constructed with its sides and bow made of flexible tubes containing pressurised gas It is meant for serious whitewater and is usually difficult to use for flat water travel.

Outrigger canoe
A canoe with an attached float, called an outrigger (or ama), to provide stability. The outrigger canoe ( Tagalog and Indonesian: bangka; Maori: waka ama; Hawaiian: waʻa; Tahitian: An outrigger is a part of a boat's Rigging which is rigid and extends beyond the side or Gunwale of a boat Commonly used for racing.

Differences from other paddled boats

Use

Canoes have a reputation for instability, but this is not true if they are handled properly. For example, the occupants need to keep their center of gravity as low as possible. Canoes can navigate swift-moving water with careful scouting of rapids and good communication between the paddlers.

When two people occupy a canoe, they paddle on opposite sides. For example, the person in the bow (the bowman) might hold the paddle on the port side, with the left hand just above the blade and the right hand at the top end of the paddle. Port is the nautical term (used on Boats and Ships) that refers to the left side of a ship as perceived by a person on board the ship and The left hand acts mostly as a pivot and the right arm supplies most of the power. The sternman would paddle to starboard, with the right hand just above the blade and the left hand at the top. Starboard is the nautical term that refers to the right side of a vessel as perceived by a person on board a vessel and facing the bow (front For travel straight ahead, they draw the paddle from bow to stern, in a straight line parallel to the gunwale.

Tandem Canoe Steering

The paddling action of two paddlers will tend to turn the canoe toward the side opposite that on which the stern paddler is paddling. Thus, steering is very important, particularly because canoes have flat-bottomed hulls and are very responsive to turning actions. Steering techniques vary widely, even as to the basic question of which paddler should be responsible for steering.

Among experienced white water canoeists, the stern paddler is primarily responsible for steering the canoe, with the exception of two cases: The bow paddler will steer when avoiding rocks and other obstacles that the stern paddler cannot see. Also, in the case of back ferrying, the bow paddler is responsible for steering the canoe using small correctional strokes while back paddling with the stern paddler.

Among less-experienced canoeists, the canoe is typically steered from the bow. The advantage of steering in the bow is that the bow paddler can change sides more easily than the stern paddler. Steering in the bow is initially more intuitive than steering in the stern, because to steer to starboard, the stern must actually move to port. On the other hand, the paddler who does not steer usually produces the most forward power or thrust, and the greater source of thrust should be placed in the bow for greater steering stability. Thrust is a reaction force described quantitatively by Newton 's Second and Third Laws.

Paddle strokes

Paddle strokes are important to learn if the canoe is to move through the water in a safe and effective manner. Categorizing strokes makes learning them easier. After the strokes are mastered, they can be combined or modified so that maneuvers are accomplished in an efficient, effective, and skillful manner. Here are the primary strokes:

In tandem canoes, complementary strokes are selected by the bow and stern paddlers in order to safely and quickly steer the canoe. It is important that the paddlers remain in unison, particularly in white water, in order to keep the boat stable and to maximize efficiency.

There are some differences in techniques in how the above strokes are utilized.

Setting poles

On swift rivers, the stern man may use a setting pole. "Riverine" redirects here For the use of that term in Maritime geography, see there A setting pole is a pole, handled by a single individual made to move Watercraft by pushing the craft in the desired direction It allows the canoe to move through water too shallow for a paddle to create thrust, or against a current too quick for the paddlers to make headway. With skillful use of eddies, a setting pole can propel a canoe even against moderate (class III) rapids. In Fluid dynamics, an eddy is the swirling of a Fluid and the reverse current created when the fluid flows past an obstacle

Gunwale bobbing

A trick called "gunwale bobbing" or "gunwaling" allows a canoe to be propelled without a paddle. The canoeist stands on the gunwales, near the bow or the stern, and squats up and down to make the canoe rock backward and forward. This propulsion method is inefficient and unstable; additionally, standing on the gunwales can be dangerous. However, this can be turned into a game where two people stand one on each end, and attempt to cause the other to lose balance and fall into the water, while remaining standing themselves.
