A kayak is a small, narrow boat that is propelled with paddles that have double blades. The Greenlandic language is the origin of the term. The term canoe is used instead of kayak in the United Kingdom. The vessel is made so that the deck is covered and it may incorporate a single or multiple cockpits. Only one paddler can sit in the cockpit. To prevent water from entering the cockpit, the cockpit may be covered with spray decks. When one needs a good kayak Nashville is home to some of the best designers.
The name kayak is still claimed by modern boats that are designed differently from the traditional ones. For example, they have flat tops where paddlers sit instead of cockpits. The boats are also surrounded by air inflated chambers on the sides. Propulsion is done using mechanical means instead of manual propulsion and they incorporate two hulls. Outboard gas engines and electric motors are some of the means of propulsion used.
The way kayaks are designed is a matter of trade-offs. The designers have to pick between stability and maneuverability, stability and speed, and primary stability and secondary stability. Generally, kayaks with longer hulls travel faster than those with short ones. Thus, vessels that are meant for covering long distances such as in sea kayaks and touring have longer hulls. Generally, they are 16 to 19 feet in length.
Kayaks used in rivers are made shorter in order to maximize maneuverability. In white waters, forward motion happens as a result of the force of the water. The normal length for whitewater kayaks is 8 feet while play boats may be as short as 5 to 6 feet in length. In recreational kayaks, stability is valued more than speed and a compromise is made between tracking and maneuverability in the design.
Unlike before when designers and producers made kayaks for personal use, modern-day producers produce for sale. Production is done using various materials such as wood, plastic, skin, polyethylene, fiberglass. Fiberglass-made hulls exhibit more stiffness that those constructed from polyethylene. However, hulls constructed from fiberglass are prone to getting damaged by impact. They are more costly because the process through which they are produced is also more complicated.
There are many differences between modern and traditional kayaks in various respects. The differences are in conception, initial form, usage, design, and construction. There is a lot of sophistication and efficiency incorporated in modern vessels. They are customized for naval design and CAD and other computer-aided tools are used to make the designs.
Modern kayaks are used for various applications. The uses range from complex maneuvering and racing to placid-water touring. They can also be used for fishing and excursions in the deep parts of the ocean. The modern forms, construction techniques, and materials make the boats suitable for various applications but still maintain insights from original Arctic inventors.
Kayaks found use in the military during the Second World War. Several units in the British navy used these vessels widely to conduct a number of sea operations including reconnaissance. The US military also has a history of using the vessels. The modern models can be launched from surfaced or submerged submarines or from military aircrafts.
