Canoe

A B. N. Morris wood-and-canvas canoe built in 1910

A canoe (North American English) or Canadian canoe (British English) is a small narrow boat, typically human-powered, though it may also be powered by sails or small electric or gas motors. Canoes usually are pointed at both bow and stern and are normally open on top, but can be decked over (i.e. covered, similar to a kayak).

In its human-powered form, the canoe is propelled by the use of paddles, usually by two people. Paddlers face in the direction of travel, either seated on supports in the hull, or kneeling directly upon the hull. Paddling can be contrasted with rowing, where the rowers usually face away from the direction of travel and use mounted oars (though a wide canoe can be fitted with oarlocks and rowed). Paddles may be single-bladed or double-bladed.

The oldest recovered canoe in the world is the canoe of Pesse[1] (the Netherlands).[2] According to C14 dating analysis it was constructed somewhere between 8200 and 7600 BC.[2] This canoe is exhibited in the Drents Museum in Assen, Netherlands.

Sailing canoes (see Canoe sailing) are propelled by means of a variety of sailing rigs. 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.

  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 used to increase hull strength. Often serves the secondary purpose of providing a lashing point to secure dry bags and other gear.
  6. Gunwale (pronounced gunnel) - the reinforcing strip running along the top edge of the hull to which the thwart(s) are attached, usually made of wood, aluminum, or polyester.
  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):

The portion of the hull between the waterline and the top of the gunwale is called the freeboard.

Stretching canvas on a canoe
Nameplate on a Gerrish — the earliest wood-and-canvas canoe
The earliest commercial builder of wood-and-canvas canoes appears to be Evan H. Gerrish of Bangor, Maine. Gerrish, a hunting and fishing guide from Brownwille, Maine, who came to Bangor in 1875 ... started experiments with a wood-and-canvas building system. ... by 1878 Gerrish was regularly producing about 18 canoes a year at his shop at 18 Broad Street. By 1882 he had hired his first employee and was building about 25 canoes a year at the average price of $25 each. The reputation of the canvas canoe was spreading to the recreational market. Gerrish already had customers far from Maine, and in 1884 he was producing over 50 canoes annually and had sent several canoes to an exhibit at the New Orleans Exposition.

Soon other companies up river from Bangor were developing their own canvas canoes and improving the manufacturing process. B.N. Morris started the Veazie Boat and Canoe Company on the second floor of his home in Veazie in 1887. It soon became the B.N. Morris Canoe Company, and for a long time it was one of the largest and best known canoe companies in the world until a fire destroyed the factory in 1920.

Up river from Veazie, at Gilman Falls, E.M. White started producing canoes in 1888. In an interview in 1901 in the Old Town Enterprise, Mr. White told how he became interested in building canvas canoes. "I saw a man by the name of Evan Gerrish of Bangor riding in the Penobscot River in a canvas-covered canoe. I quickly saw the advantages of that kind over my birchbark, which moreover leaked. I examined the canvas canoe closely, and in a short time was able to produce one which was so good someone wanted to buy it." White started building canoes at his Gilman Falls family home by boiling ribs in his mother's washtub and using a horse on a treadmill for power. White's brother-in-law, E.L. Hinckley, became a working partner and provided the capital to open a large shop in nearby Old Town. The Carleton Boat and Canoe Company of Old Town built batteaux and bark canoes in the 1870s. Carleton appears to be the only one of the batteaux and/or bark builders who switched to building canvas canoes and as such was the only one who brought any previous boat building experience to the industry. Carleton was later bought by the Old Town Canoe Company in the early 1920s.[4]

In the adjoining Canadian province of New Brunswick, from the late 1800s until being disbanded in 1979, the Chestnut Canoe Company, along with the Old Town Canoe Company in Maine, became the pre-eminent producers of wood-and-canvas canoes. American President Teddy Roosevelt purchased Chestnut canoes for a South American expedition. Wood-and-canvas canoes have undergone a resurgence in recent years, spurred in part by the Wooden Canoe Heritage Association.[5] Builders abound, including Jerry Stelmok,[6] Rollin Thurlow,[7] Ken Solway,[8] Joe Seliga, and many others.[9]

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. 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 (5.49 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 1+12 to 2 horsepower (1.1 to 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. 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.

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. Primitive replica canoes fabricated from animal pelt and other natural materials often utilize green branches and other flexible, organic material to retain a buoyant form while resisting risk of puncture or abrasion.

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 (the hull's tendency to travel a straight line without the need for constant course correction). Specialized canoes for whitewater play have an extreme rocker and therefore allow quick turns and tricks. Increased rocker also tends to increase the stability of a 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. A 35 millimeters (1.4 in) rocker at each end suffices to make a substantial 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

In the past, people around the world have built very different kinds of canoes, ranging from simple dugouts to large outrigger varieties. 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:

Dcp 5863.jpg
Dugout
Formed of hollowed logs; may have outriggers in some cultures. On the west coast of North America, large dugout canoes were used in the Pacific Ocean, from fishing to whaling.

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.

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.

War canoe
War canoes have been extensively used in Africa to transport troops and supplies, and engage targets onshore. While documentation of canoe versus canoe battles in on the open ocean is rare, records from the 14th century mention various tribal peoples of West Africa using huge fighting canoes in inland waters, some up to 80 feet (24 m) and carrying over 100 men.[12] Construction of the war canoe was typically from one massive tree trunk, with the silk cotton tree being particularly useful. The inside was dug out and carved using fire and hand tools. Braces and stays were used to prevent excessive expansion while the fire treatment was underway. Fire also served to release sap as a preservative against insect pests. Some canoes had 7 to 8 feet (2.4 m) of width inside, accommodating benches for rowers, and facilities such as fireplaces and sleeping berths.

Warriors onboard were typically armed with shield, spear and bow. In the gunpowder era, small iron or brass cannon were sometimes mounted on the bow or stern, although the firepower delivered from these areas and weapons was relatively ineffective. Musketeers delivering fire to cover raiding missions generally had better luck. The typical tactic was to maneuver close to shore, discharge weapons, then quickly pull out to open water to reload, before dashing in again to repeat the cycle. Troop and supply transport were the primary missions, but canoe versus canoe engagements in the lagoons, creeks and lakes of West Africa were also significant.[13]

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 and Tripping canoes.
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. Touring canoes are often made of lighter materials and built for comfort and cargo space; whereas Tripping canoes (such as the Chestnut Prospector derivates, and the Old Town trippers), are typically made of heavier and tougher materials, and are of course usually a more traditional design.
Keji canoe.jpg
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, 4 mm 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 long-distance touring canoe is mostly covered with a greatly extended deck, forming a "cockpit" for the paddlers. 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.
C1 Playboat.jpg
Playboating decked canoe
A subgroup of whitewater canoes specialized for whitewater play and tricks. Most are identical to short, flat-bottomed kayak playboats except for internal outfitting. The paddler kneels and uses a single-blade canoe paddle.
Dickerson-C1a.jpg
Whitewater slalom canoe
Decked canoes which look very much like a kayak, but are still paddled with the paddler in a kneeling position and with a single bladed paddle.
Square stern canoe An asymmetrical canoe with a squared off stern for the mounting of an outboard motor; meant for lake travel or fishing.
Women C-2.jpg
Racing canoe
Also known as sprint canoe - purpose-built racing canoe for use in racing on flat water. To reduce drag, they are built long and with a narrow beam, which makes them very unstable. A one-person sprint canoe is 5.2 meters or 17 feet (5.2 m) 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.
Aa inflatable canoes.jpg
Inflatable canoe
Similar in construction and materials to other inflatable boats but shaped like a canoe. It is meant for serious whitewater and is usually difficult to use for flat water travel.
Outriggercanoe.jpg
Outrigger canoe
A canoe with an attached float, called an outrigger (or ama), to provide stability. 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. 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. For travel straight ahead, they draw the paddle from bow to stern, in a straight line parallel to the gunwale.

Tandem 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 paddler must actually switch 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.

On flat water, a turn can also be made by simply leaning the canoe towards the outside of the turn while paddling normally with a forward stroke.

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.[14] Here are the primary strokes:

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

Setting poles

On swift rivers, the stern canoeist may use a setting pole. 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.

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.
