A Sea kayak or touring kayak is a kayak developed for the sport of paddling on open waters of lakes, bays, and the ocean. Sea kayaks are seaworthy small boats with a covered deck and the ability to incorporate a spraydeck. They trade off the extreme maneuverability of whitewater kayaks for cargo capacity, ease of straight-line paddling, and comfort for long journeys.
Sea kayaks are now used around the world for marine journeys from a few hours to many weeks, as they can accommodate one or two (occasionally three) paddlers together with room for camping gear, food, water, and other supplies. The sport of sea kayaking (sometimes called ocean kayaking) combines much of the appeal of hill-walking with a maritime aspect, few access issues and a seemingly unlimited area to enjoy.
Origins
Contemporary sea kayaks trace their origin to the native boats of Alaska, northern Canada, and Southwest Greenland. Eskimo hunters developed a fast sea going craft to hunt seals and walrus.The ancient Aleut name for a sea kayak is Iqyak, and earliest models were constructed from a light wooden frame (tied together with sinew or baleen) and covered with sea mammal hides. Archaeologists have found evidence indicating that kayaks are at least 4000 years old. Wooden kayaks and fabric kayaks on wooden frames (such as the Klepper) were dominating the market up until 1950s, when fiberglass boats were first introduced. Rotomolded plastic kayaks first appeared in 1984.
Design
Modern sea kayaks come in a wide array of materials, designs, and sizes to suit a variety of intended uses. The primary distinction is between rigid kayaks and folding kayaks. While many modern kayaks carry the design features of traditional craft, recent design innovation includes:
- shorter sea kayaks with wide beams and large cockpits;
- rotomolded boats without an enclosed cockpit, but with some other sea kayak features;
- sometimes employing a rigid frame with inflatable sponsons; and
- long, narrow boats intended for open ocean racing.
SizeMost production sea kayaks are between and in length, the larger kayaks often built for two (or in rare cases, three) paddlers. The width|beam]]) of typical kayaks varies from to , though specialized boats such as surf skis may be narrower. The length of a kayak affects not only its cargo capacity (for both gear and paddlers) but may also affect its "tracking" ability -- the ease with which the boat travels in a straight line. While other design features also impact tracking, very long kayaks are easier to paddle straight (and harder to turn). The width of a kayak affects the cargo capacity, the maximum size of the cockpit (and thus the size of the paddler in that cockpit), and (to a degree that depends on the design of the hull) the stability.
MaterialMost rigid production kayaks are now made out of fiberglass, rotomolded polyethylene, or carbon-kevlar. More exotic materials include carbon fiber and foam core. Some kayaks are hand-built from plywood or wood strips covered with fiberglass. Skin-on-frame kayaks are built on wood or aluminum frames covered in canvas, dacron, or other fabrics, and may include inflatable tubes called sponsons.
Bow, stern, and deckThere are many design approaches for the bow, stern, and deck of kayaks. Some kayaks have upturned bows, which are meant to provide better performance when paddling into waves, as well as better wave-shedding ability. Other kayaks achieve this through increased buoyancy in the bow. Kayaks with unobstructed stern decks may ease certain types of self-rescue. Waterproof bulkheads in modern kayaks provide flotation in the event of capsize.
Sea kayak decks typically include one or more hatches for easy access to the interior storage space inside. Kayak decks often include attachment points for deck lines of various kinds, which are aids in self-rescue and attachment points for above-deck equipment.
Equipment
Sea Kayaks are designed to go fast in a straight line, so many have steering gear or tracking aids in the form of rudders or skegs. In most cases rudders are attached at the stern and operated by wires from foot pedals in the cockpit. Rudders are typically retractable for beach landings. Skegs are straight blades that drop from a well in the stern of the boat. Both devices assist in paddling when a strong wind is coming from a direction other than directly in front.
PaddlesSea-kayak paddles, and the associated paddling styles, fall into three basic classifications:
- two roughly spoon-shaped blades at either end of a cylindrical shaft. This paddle style was developed for fast acceleration and sudden maneuvering in Whitewater kayaking, and then back-ported to sea-kayaking. Euro paddles can be made of aluminum, plastic or even wood, but the best are usually formed of more expensive materials like carbon-fiber for lightness. Often the two blades are feathered, or set at an angle relative to each other (both for ergonomic efficiency, and so that as one blade moves backwards through the water, the opposite blade moving forward through the air presents its edge, rather than its face).
- Relatively narrow blades which are rounded and full near the loom and blade roots, and becoming oval near the blade tips. Some paddles feature a "shoulder", or abrupt transition between the loom and blade roots. Greenland paddle blades are most often not feathered. Short Greenland paddles (generally one arm-span in length), called storm paddles, are used with a sliding stroke, where the hands are shifted along the blades for each stroke. Storm paddles are often used as spares and in very windy locations, as there is very little outboard blade to catch the wind.
- The blade of the paddle is shaped with a profile like a wing. When used with a special stroke, the blade actually produces lift as it moves through the water, enabling the kayaker to produce more forward motion than with any other kind of paddle. The paddling technique is different from both European style paddles and Greenland style. It is most often used in racing, but also sees some limited use in recreational paddling such as touring.
DimensionsSea kayaks come in many different designs. The length of a typical solo sea kayak can range anywhere from 12 to 18 feet (3.7m-5.5m) long, and tandem kayaks can range from to 20 feet(4.6m-6.1m) long. Sea kayaks can range in width from to 30 inches (57cm-76cm). Wider touring kayaks of to 30 inches (66-76cm) are better for bigger paddlers, or small/average sized paddlers looking for more initial stability and manouevrability. Narrower beams of to 25 inches (56cm-63.5cm) are good for small-medium sized paddlers who want more speed and less manoeuvrability. And lastly, kayak depth (or the height from the hull to the highest area of the deck) can range from to 15.8 inches (33cm-40cm) high.
This design is typical of modern sea kayaks and has a low rear deck for easy rolling, a white water cockpit, compartments that allow the kayaker to reach into the compartment while at sea and a sloping rear bulkhead that enables the kayak to be emptied by lifting the bow.
Forms of sea kayaking
Kayak Sailing
Developed by kayak enthusiasts, kayak sails enhance the paddling experience. Kayak sails such as the WindPaddle either augment the effort of paddling or effectively eliminate the need for paddling. They are great for touring, and have established a strong following with recreational sea kayakers, expedition paddlers and adventure racers.
Expedition Trips
Weekend trips with overnight camping are popular amongst recreational kayakers, and many people combine kayaking with watching wildlife. Modern sea kayaks are designed to carry large amounts of equipment, and unsupported expeditions of two weeks or more are conducted in environments from the tropics to the Arctic. Expedition kayaks are designed to handle best when loaded, so it may be necessary to ballast them on shorter trips.
Surf KayakingClosely related to surf boards and requiring a mix of surfing and kayaking skills, a wide range of sea kayaks are specifically designed for the sport of wave surfing.
Sea Fishing
The sea kayak has long been a means of transportation and a means of accessing fishing grounds and kayak fishing has gained popularity due to the availability of purpose built stable designs. This technological development also solves some ergonomic problems that are associated with sitting for long hours without being able to change positions and special kayaks for fishing are accessorized for this sport, including specially-designed hatches, built-in rod holders, catch bags and equipment mounts.
Many of the techniques used in kayak fishing are the same as those used on other fishing boats. The difference is in the set-up, how each piece of equipment is fitted to the kayak, and how each activity is carried out on such a small craft. Contemporary kayaks can be equipped with fishing aids such as rod holders, electronic fish-finders and live-bait containers. Kayak anglers target highly-prized bottom feeders like halibut and cod and also pelagics like amberjacks, tuna, sailfish, wahoo, and even marlin.

SafetyA sea kayak's primary safety device is its paddler. Some kayakers consider a well-practiced self-righting move such as an Eskimo roll to be essential to safe open-water kayaking, though this can be difficult in a heavily-laden boat. While there are a number of techniques for unassisted righting and re-entry of a kayak after a capsize, most paddlers consider it safest to paddle with one or more others, as assistance is useful if attempting to roll up solo fails. Even if the assistance fails to get you righted, it's a lot easier to climb back into a boat in the open sea if you've got another boat and paddler to help and your boat's been emptied of water first. Nonetheless, experienced paddlers do attempt open water crossings unaccompanied, and several major long-distance kayak expeditions have been carried out solo.
There is a strong culture of self-sufficiency amongst sea kayakers and extensive safety equipment such as compass, towing lines, manual pumps, repair kits including wet application repair tape, flares, spare paddles, and survival gear are routinely carried; along with supplies of food and a flask of hot coffee for non-emergency use. GPS, charts, lights, radios and cell phones, and radar reflectors are also sometimes carried.
