The conquest of

the Atlantic Ocean

Because the oceans are contribute to the Atlantica project

the great crossing

Through her mission to become the first woman to cross the Atlantic from one continent to another, Heidi and her team are devoting this extreme swimming to one of the most current and imperative environmental concerns: water, oceans and their ecosystems.

The project

The mission

Project Atlantica’s mission is to propel the achievement of a world first in swimming: the Atlantic Crossing. Heidi Levasseur, a French Canadian, has the ambition to sign this feat and moreover, to dedicate this expedition to the protection of oceans at risk by plastic pollution.

A record

On each of the swimming days, the GPS coordinates will be recorded at the beginning and end of the session, to ensure that in the end, each km has been swum. Evidence of the feat will be forwarded to WOWSA for approval. It should be noted that no woman has achieved such a feat and that a man has made a crossing of the Atlantic, without otherwise providing evidence of the distance actually traveled to swim between two continents.

A superhuman challenge?

With more than 3000 km between the city of Dakar in Senegal and the city of Recife in Brazil, the athlete will have to push back his physical and psychological limits and believe in his abilities. Possessing a very rich open water swimming experience and surrounded by a competent team, the winning bet plays in his favor. Heidi will be surrounded by a safety boat (Catamaran 56 ‘) with a crew of seven. She will swim between 7 and 8 hours a day and will be assisted by a kayaker during her swimming sessions. Heidi and his team estimate between 4 and 6 months the duration of this epic expedition, in an environment where the weather and the vagaries of nature can be unpredictable.

An environmental echo

To raise awareness and promote the protection of oceans, the marine environment and renewable energies.

A humanitarian message to the peoples

This epic expedition rises above the sporting feat and joins many spheres of the human dimension, while recalling universal values of unity, peace and human rights freedoms. Taking the road between Africa and Brazil, which reminds us of the sad story of the slave trade, the young woman, originally from America, reaches out to all nations, to bring people together and to awaken the consciences to this approximation that offers us the sea.

The course

The crossing

The route

  • Departure: Dakar, Senegal (december 2020)
  • Arrival : Brasil (spring 2021)
  • Estimated time : 120 to 180 days
  • Stop : None
  • Refueling or partial relief of crew: two contacts planned
  • Total distance : ≈3000 kms

The vocation

Through her mission to become the first woman to cross the Atlantic from one continent to another, Heidi and her team are devoting this extreme swimming to one of the most current and imperative environmental concerns: water, oceans and their ecosystems. Indeed, water and marine ecosystems are issues that affect us at every level of our food chain.

Affected by the pollution of our industrial and economic activities, the situation becomes dramatic in many places in the world and very quickly, our survival will depend on it …


An accompanying ship and a crew will follow the swimmer. This vessel will comply with international regulations (IMO), ensure the safety of the swimmer and provide adequate rest and recovery space for both her and the expedition crew.

Members of the expedition

  • Master of Shipping and Captain, Professional Sailor
  • Deputy Master of Shipping (Second), Professional Marine
  • Mechanic
  • Cook (optional) Professionnal marine
  • Sea Kayaker (Rescuer) Swimmer Safety
  • Cameraman, Documentary, videos, photos
  • Paramedical: massage and recovery, Daily Swim Care
  • Doctor, Health / Safety swimmer and crew

Swimming sessions

The swimmer will be at sea by day only and will do two sessions of four hours of swimming and this, 5 to 6 days per week, thus providing a distance of 20 to 25 km daily.

Supervision and safety of the athlete

The supervision of the swimmer will be provided by two crew members at all times:

  • the sea kayaker will supervise and guide the swimmer at a distance of a few meters during swimming sessions;
  • the captain will monitor the swimmer’s position using his control instruments and will be able to observe the imminent threats with sonar.

Ground crew

This team ensures and coordinates the work to be done in a terrestrial and virtual environment, so that the goals of the expedition are achieved. The news, the swimmer’s GPS position and the external communications will be managed by a team working on three continents.

GPS tracking

So that you can follow me daily in this odyssey, an Atlantic map will be visible at any time on my website, allowing you to regularly know my position in the Atlantic during each day.


The planned diet plan consists of a balanced menu checked by a nutritionist.

Since we will be at sea for several months, the possibility of getting fresh food is very limited. That’s why most of our staple foods will be dry and need to be rehydrated so that they can be cooked.

Since we value and promote eco-responsible behavior, we have chosen to feed ourselves with vegetarian dishes.


At the end of each swimming session, I will return aboard the catamaran, to give an account of my session, rest and receive therapeutic care.


The most favorable time of year, chosen according to the data recorded on the Pilots Charts, corresponding to the risks of tropical storms, is from November to April. The boat, dedicated to expedition, will be able to withstand the ocean conditions and will offer all the space required for the needs of the crew, as well as a certain comfort and stability.

Marine animals

Various safety mechanisms will be used to supervise the swimmer and offer maximum safety;

  • shark repellent liquid (Shark repellant) and shark ultrasonic (Shark shield)
  • sonar, multibeam echosounder that will be used to recognize the movements of marine animals;
  • striped jumpsuit creating confusion for some predators and a
    tactile protection against jellyfish stings;
  • time limit for swimming on sunny periods: entry to the water one hour after sunrise, exit one hour before bedtime;
  • drones-camera to identify some OFNI out of sight of the crew.


A doctor will be on board. He must have experience at sea and be able to assist the athlete regularly, as well as any crew member requiring care.

There will also be at least one other crew member holding the STCW2010 Medical Professional Certificate.

Confinement at sea

A psychological resource that can be reached and reached ashore when needed.

Previous attempts

Here is a summary of the tests done in the past


Guy Delage undertakes a swim from Cape Verde to Barbados (2,100 nautical miles) in 55 days, using an autonomous raft that sails adrift while he sleeps. According to the records, it will take 55 days to reach the Caribbean, however the distance traveled during the drift was not recorded and no witness authenticated the feat.


Benoit Lecomte, swam from Hyannis, (USA) to Quiberon, (France) in 73 days (3,716 nautical miles). During this expedition, he swam 8 hours a day and two security ships assisted him. He made a 6-day stopover in the Azores. In addition, taking into account the duration and distance traveled, the speed of swimming recorded by a simple calculation, corresponds to a swimming speed of about 8 miles per hour. It would be impossible to achieve or maintain. Assuming that a portion of the trip was made by drifting his accompanying ship during his daily rest periods, it is not known exactly how many kilometers he swam.


Jennifer Figge, swam from the Cape Verde Islands to Chacachacare Island, Trinidad. It swam only part of the distance out of a total of 2,160 nautical miles. She uses a shark cage during her swimming sessions (up to 8 hours a day) fighting against strong winds and waves up to 30 feet. Originally she had planned to swim in the Bahamas, but she had exceeded 1,000 miles (1,600 km).


Jennifer Figge, swam from Cape Verde to Trinidad for a period of 31 days. Swimming six hours a day, 17 miles a day, she swam 139 hours and 25 minutes and totaled 300.86 miles on a course of 2.186 miles.


Figge undertook another expedition. This time, she swam a total distance of 257.5 nautical miles (477 km) over a 32-day period. She left Cape Verde on April 8 and landed on the shores of Antigua in the Caribbean Sea on May 9, 2013.


Ben Hooper, a British, started swimming from Dakar (Senegal) to Natal (Brazil). He wanted to become the first man to swim the full distance between two continents due to 8 hours of swimming a day, promising a return to his GPS position every morning. Mechanical breakdown and health problem (multiple jellyfish burns) forced him to give up after a little more than a month at sea and less than 200 kms of swimming.



Dynamic and interactive conferences.

The objectives of the conferences are: motivation, surpassing oneself, the environment and the protection of water in particular.

Conferences adapted to primary or secondary schools, early childhood centers, companies, organizations, associations, special activities or training … Many concrete examples on different topics for the mobilization of all towards a better future.
