A jetboard is a motorized surfboard, where the rider controls the speed using a handheld remote control (wireless or tethered) and uses the bodyweight transfer to maneuver the board. The driveline typically consists of a water jet module (similar to what is found in a PWC), and either a combustion engine or a battery powered electrical motor.
Jetboards remove the difficulties of conventional surfboards as they can be ridden without wind or waves. There is also no need for paddling, as the boards can be ridden at the touch of a button. Compared to traditional surfing, jetboarding can be easily learned and allows the user to become proficient in a short time. This makes this water sport suitable for a large audience of different physical conditions, ages, experience levels and riding styles. In addition, jetboarding can take place on lakes, rivers, canals, seas and oceans alike, making it further accessible to larger groups of people. In addition to private ownership, rental operations are becoming available at places resorts and boating hotspots. In addition, jetboards are also becoming a popular choice as toys for yachts, sailing boats and catamarans.
Alongside other electrically powered board embodiments, such as efoils, jetboards are gaining in popularity worldwide and are poised to become a permanent addition to traditional water sports.
Motorized surfboards have existed as hobbyist projects in various designs since at least the 1930’s, originally in the shape of regular wooden surfboards with small engines attached. [1] [2] [3] [4] In the 1960’s, the first commercially marketed jetboards were launched. The Jet Board, developed by Alfred Bloomingdale, is perhaps the most well-known. While it contains several features prominent in today’s keyboards (such as a magnet leash kill-switch [5] ), it can be discussed whether the product was in fact a jetboard, seeing as its main purpose was to relieve a surfer of the paddling part of wave surfing. Another inventor, George Carter, introduced his product Surfjet in the same year. Development of various motorized surfboards continued throughout the twentieth century, [6] [7] [8] but it wasn’t until electrification was introduced in the 2010’s, that jetboards started to become relatively widespread. By means of electrical DC motors and rechargeable lithium-ion batteries, companies like Radinn, Lampuga, Jetsurf and Onean have been developing jetboards that are much easier to maintain and use, compared to their combustion engine ancestors, in addition to becoming very powerful and fast [9]
Since 2012, jetboarding races has been organized by the MotoSurf World Cup, [10] based in Czechia. In the competitions, petrol powered and electric jetboards compete in separate classes.
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy.
Surfing is a surface water sport in which an individual, a surfer, uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suitable for surfing are primarily found on ocean shores, but can also be found in standing waves in the open ocean, in lakes, in rivers in the form of a tidal bore, or in wave pools.
A surfboard is a narrow plank used in surfing. Surfboards are relatively light, but are strong enough to support an individual standing on them while riding an ocean wave. They were invented in ancient Hawaii, where they were known as papa he'e nalu in the Hawaiian language, and were usually made of wood from local trees, such as koa. They were often over 460 cm (15 ft) in length and extremely heavy. Major advances over the years include the addition of one or more fins (skegs) on the bottom rear of the board to improve directional stability, and numerous improvements in materials and shape.
Mavericks is a surfing location in northern California outside Pillar Point Harbor, just north of the town of Half Moon Bay at the village of Princeton-by-the-Sea. After a strong winter storm in the northern Pacific Ocean, waves can routinely crest at over 25 ft (8 m) and top out at over 60 ft (18 m). Routinely, waves that break can be recorded on seismometers. The break is caused by an unusually shaped underwater rock formation.
Laird John Hamilton, né Zerfas, is an American big-wave surfer, co-inventor of tow-in surfing, and an occasional fashion and action-sports model and actor. He is married to Gabrielle Reece, a former professional volleyball player, television personality, and model.
A foilboard, also known as a hydrofoil board or foil surfboard, is a type of board used in water sports; it is distinct from surfboards in that it has a hydrofoil rather than fins mounted underneath. This hydrofoil design allows the surfboard and its rider to rise above the water’s surface, allowing for fast speeds and increased maneuverability in a wide range of surf conditions. Foilboards are becoming increasingly popular across many water sports, including surfing, kiteboarding, and wakeboarding. Foilboards have also been used in competitions, with riders reaching speeds of up to 30 km/h while performing acrobatic maneuvers such as flips, twists, and more.
The Waveski, previously known as the "Paddle Ski” is a surfboard where the rider 'sits' on top of the surfboard. Waveski surfing is a dynamic sport combining paddle power with the manoeuvrability and performance of a surfboard. A Waveski resembles a larger volume surfboard, with the addition of a hollowed out seat with seat belt, foot straps and double ended paddle enabling the rider to remain attached to the board for maneuvers and to 'Eskimo roll' if overturned. The waveski rider or surfer uses a double-ended paddle while seated. To turn the rider uses his weight to lean on the side rails and paddle to pivot or propel the board up the wave. The sport is categorized under the International Canoe Federation. The discipline holds biennial World championship events, the next of which will be held at the Nahoon Reef, outside the town of East London, South Africa.
A motorized bicycle is a bicycle with an attached motor or engine and transmission used either to power the vehicle unassisted, or to assist with pedalling. Since it sometimes retains both pedals and a discrete connected drive for rider-powered propulsion, the motorized bicycle is in technical terms a true bicycle, albeit a power-assisted one. Typically they are incapable of speeds above 52 km/h (32 mph), however in recent years larger motors have been built, allowing bikes to reach speeds of upwards of 72 km/h.
This timeline of motorized bicycle history is a summary of the major events in the development and use of motorized bicycles and tricycles, which are defined as pedal cycles with motor assistance but which can be powered by pedals alone.
The riding of waves has likely existed since humans began swimming in the ocean. In this sense, bodysurfing is the oldest type of wave-catching. Undoubtedly ancient sailors learned how to ride wave energy on many styles of early boats. Archaeological evidence even suggests that ancient cultures of Peru surfed on reed watercraft for fishing and recreation up to five thousand years ago. However, standing up on what is now called a surfboard is a relatively recent innovation developed by the Polynesians. The influences for modern surfing can be directly traced to the surfers of pre-contact Hawaii.
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems.
Lake surfing is surfing on any lake with sufficient surface area for wind to produce waves. As with ocean surfing, ideal wave conditions are when the wind switches offshore. However, when this occurs over a lake the waves generated by previous onshore wind subside relatively quickly. This means lake surfers have a shorter window of opportunity to surf ideal waves. Lake surfers are often out during and experiencing the same storm that creates the waves whereas ocean surfers are more often surfing on swell produced by storms hundreds of miles away and that may have taken days to reach shore. In addition to making it more difficult to manage surfboards, high winds can make the face of a wave and water surface rough. Increased wave frequency due to shorter fetch results in less rest between waves and sets of waves. This can make it necessary to paddle out through waves because there may not be a long enough pause between sets to paddle out between them.
Paddleboarding is a water sport in which participants are propelled by a swimming motion using their arms while lying or kneeling on a paddleboard or surfboard in the ocean or other body of water. Paddleboarding is usually performed in the open ocean, with the participant paddling and surfing unbroken swells to cross between islands or journey from one coastal area to another.
The Noosa Festival of Surfing was established in 1992 at Noosa, Queensland by members of the Noosa Malibu Club, as an amateur surfing competition called the Noosa Malibu Classic. It allowed club members to invite friends to surf Noosa's right-hand point breaks and the event's popularity among competitive longboarders gave the club a chance to take the event to a higher level. In 1996 a professional division was introduced and prompted the name change to The Noosa Festival of Surfing (NFoS) in 1998. The World Tandem Surfing Championships were brought to Noosa in 1999 and Stand up paddle surfing was incorporated into the festival in 2007 with live entertainment and fundraising auctions also being held. In 2008, the festival, sponsored by Global Surf Industries and maintained and managed by USM Events, commenced with the traditional Mixing of the Waters ceremony led by Hawaiian waterman Brian Keaulana. The Noosa Festival of Surfing is an official Association of Surfing Professionals (ASP) Longboard rated event.
Standup paddleboarding (SUP) is a water sport born from surfing with modern roots in Hawaii. Standup paddleboarders stand on boards that are floating on the water and use a paddle to propel themselves through the water. The sport was documented in a 2013 report that identified it as the outdoor sporting activity with the most first-time participants in the United States that year. Variations include flat water paddling, racing, surfing, whitewater SUP, yoga, and fishing.
This glossary of surfing includes some of the extensive vocabulary used to describe various aspects of the sport of surfing as described in literature on the subject.[a][b] In some cases terms have spread to a wider cultural use. These terms were originally coined by people who were directly involved in the sport of surfing.
Mark Robert Visser is an Australian professional big wave surfer, author, keynote speaker and ocean adventurer. Visser is best known for being the first person to surf Hawaii's most dangerous wave Jaws, Maui, at night in 2011. It was documented in a film called 'Night Rider'.
Surfing in the United States is a popular hobby in coastal areas, and more recently due to the invention of wave pools, inland regions of the country. It contributes to a lifestyle and culture in which millions participate and which millions more have an interest. USA surfing is the governing body for the sport of surfing in the United States, with surf leagues such as the World Surf League available in the country. Surfing can be traced back to 17th Century Hawaii and has evolved over time into the professional sport it is today, with surfing being included for the first time in the 2020 Summer Olympics in Tokyo.
Electric motorsport is a category of motor sport that consists of the racing of electric powered vehicles for competition, either in all-electric series, or in open-series against vehicles with different powertrains. Very early in the history of automobiles, electric cars held several performance records over internal combustion engine cars, such as land speed records, but fell behind in performance during the first decade of the 20th century.
