A kayak is a little human-powered boat. It classically has a covered deck, and a cockpit covered by a spray deck. It is propelled by a double-bladed paddle by sitting paddlers. The kayak was used by the inhabitant Ainu, Aleut and Eskimo hunters in sub-arctic regions of northeastern Asia, North America and Greenland. Modern kayaks come in a wide diversity of designs and materials for particular purposes. Kayaks are frequently referred to as canoes in Great Britain and Ireland.
Traditional kayaks typically accommodate one, two or infrequently three paddlers who sit facing ahead in one or more cockpits below the deck of the boat. If used the spray deck or comparable waterproof garment attach securely to the edges of the cockpit, prevent the entry of water from waves or spray, and making it possible in some styles of boat, to roll the kayak upright again without it filling with water or eject the paddler.
Kayaks differ definitely in design and history from canoes, which are more flat-bottomed boats propel by single-bladed paddles by a kneeling paddler, even though some modern canoes may be difficult for a non-expert to distinguish from a kayak. One benefit to a kayak is that with a canoe's high bow, it is harder to paddle against the wind. As Kayaks do not have such high sides, it is easier to paddle on a breezy day.

A hovercraft, or air-cushion vehicle (ACV), is a vehicle or craft that can be hold up by a cushion of air dispossessed downwards against a surface close below it, and can in principle travel over any relatively smooth surface, such as gently sloping land, water, or marshland, while having no substantial contact with it.
Hovercraft has one or more parts of engines (some craft, such as the SR-N6, have one engine with a drive split through a gearbox). One engine drives the fan (the impeller) which is in charge for exciting the vehicle by forcing air under the craft. The air therefore must exit throughout the "skirt", lifting the craft above the area which the craft resides. One or more additional engines are used to offer thrust in order to propel the craft in the favorite direction. Some hovercraft utilized ducting to allow one engine to perform both tasks by directing some of the air to the skirt, the rest of the air passing out of the back to push the craft forward.

Folding boat

A Folding boat is frequently a smaller boat, typically ranging between 8 to 12 feet. This style of boat must also allow for easy lifting which require a glow weight. Folding boats are made from light weight resources such as marine plywood, aluminum or more exotic man-made materials lighter and tougher than aluminum. Folding boats fill a need for people who do not have storage gap for a full-size boat or cannot transport a full-size boat.
There are more than a few folding boat makers and folding kayak makers in the world from the USA, England and Australia with several variations and models. The handyman can also produce their own unit at home with plans or buy designing their own version.
Although there is much to be thought by the advantages of a folding boat, they are not common place in boating and aluminum and inflatable alternatives are far more common despite some folding boats having been sold for several decades.
