Blokarts are highly maneuverable and able to be used in small spaces

The Blokart is a popular one-design class of small compact land yacht, manufactured by the New Zealand-based company Blokart International Ltd.[1]

They can be quickly disassembled and packed into a carry-bag giving them a high degree of portability and are designed to be particularly easy to learn to sail. They are used for leisure sailing on beaches in many parts of the world - but Blokart racing is also developing as a competitive international sport, with organised racing including national championships in several countries and a biennial world championship.

History

The Blokart design was developed in 1998 as a joint venture with Paul Beckett and Ross Dickey, Tauranga NZ.[2][3] The first commercial models made in a purpose built factory were produced in Papamoa, NZ in 2000 and since then the fundamental blokart design has remained virtually unchanged. By 2017, the total number of karts produced exceeded 14,000 with almost half of these sold in Europe.

The basic model, including wheels, mast and sail, weighs only 29 kg and can be dismantled in a few minutes without tools, and all parts packed into a carry-case. The high degree of portability allows them to be transported by car, or carried as luggage on a plane.

Blokarts can be assembled in minutes without tools

Unlike many other land yachts, the Blokart is steered using the hands via a centrally mounted bar directly coupled to the front wheel. This, along with its compact size, makes it highly maneuverable, and able to be used in small urban areas such as carparks or tennis courts.

Wheels can be replaced with ice blades to allow the Blokart to sail on ice - with the first Blokart Ice World Championships staged in Lithuania in 2010.

A side-car accessory or "Shadow" can be added to carry a passenger, and Blokarts can be joined head-to-tail together using a "Deuce" bar. Multiple can be joined in this way to create long trains.

Blokarts have four standard sail sizes, 2.0m, 3.0m, 4.0m and 5.5m, with sail size choice being dependent on wind strength and weight of the sailor. Heavier sailors require larger sails, and smaller sails are more efficient in stronger winds.

Speeds of more than 100 km/hr have been attained on land and up to 130 km/hr on ice. The current Blokart land speed record of 125 km/hr (77.7 mph) was set by Scott Young and Dave Lussier at Lake Ivanpah in Eastern California on Wednesday, 11 April 2018.[4] The record was set on the 2nd lap of the final race of the 2018 North Americans when a Haboob (desert wind storm) came across the racing area.

Adventure

In 2007 a group of 11 international adventurers crossed the Gobi Desert on Blokarts in a journey planned by French enthusiast Chrisophe Gombert of France, and Mongol guide and friend Batzorig.

Racing

Race Start at Ivanpah Dry Lake Bed, USA

Although Blokarts meet the qualification standard for mini-yachts under the FISLY regulations, they are generally sailed in separate regattas organised under the IBRA rules. The "one design" standard has helped Blokart racing spread rapidly throughout the world - with national and regional championships now being contested annually in numerous countries including: USA, Australia, NZ, Britain, Spain, Belgium, France, Denmark, Sweden, Germany, Lithuania and the Netherlands.

Blokart World Championships have been held biennially since 2008 as follows;

Year Location Country
2008 Papamoa New Zealand
2010 Ostend Belgium
2012 Ivanpah USA
2014 Perth Australia
2016 Ivanpah USA
2018 Majorca Spain
2020 Manawatu New Zealand†

† The 2020 Blokart World Championships scheduled for Manawatu, New Zealand were postponed due to the covid-19 pandemic. They are currently rescheduled for October 2022, subject to the lifting of travel restriction.

Blokart Racing is administered by the International Blokart Racing Association (IBRA) who sanction events and set the international racing rules.[5]

Setup

Racing differs to other land yacht racing - which typically has stationary starts and race across the wind on beaches. It actually has more in common with water based sailing, with 2-3 minute dial-up starts and windward/leeward courses. Racing is held on purpose built tracks, airport runways, parking areas as well as beaches and dry lake beds. Races are between 5 minutes and 8 minutes in duration.

The hand steering allows people with lower-limb disabilities to compete with able-bodied pilots.

Sail selection for racing is dependent on pilot weight and the sailing course. Heavier pilots require larger sails; tighter courses generally require a larger sail - and for straighter and more open courses a smaller sail provides less drag and therefore greater maximum speed.

Classifications

Blokarts are raced in two classes – production and performance. The production class is based on the basic design; while in the performance class additional parts from the manufacturer are allowed such as carbon fibre mast sections and an aerodynamic shell, adjustable downhaul and modification of the sail battens to alter the shape of the sail. New components must sanctioned by IBRA before they can be used in racing.

Depending on number of entries at events, Blokart classes are further broken down into weight divisions determined by the body-weight of the racer. For the Blokart world championships the 4 following divisions have been defined:

  • Lightweight Division: Less than 70 kg
  • Middleweight: From 70 kg to less than 82.5 kg
  • Heavyweight: From 82.5 kg to less than 95 kg
  • Super Heavyweight: 95 kg and greater

There is generally no differentiation of racers on the basis of age or gender.

Locations

Blokarting can be done on virtually any open area larger than the size of a tennis court. Beaches provide an ideal venue subject to tides, wind direction and density of people.
