Antoine Marquais was born in Paris in June 1979 by a German mother and a French father. 
After living 22 years in Paris and having obtained an Art History degree in Paris X Nanterre, he started his schooling in graphic design in Brussels (CAD). After a year in CAD, he was hired by one of his teachers to work with her in website design.
He worked for a few years in graphic and web design while practicing intensively in wakeboarding.
This led him to slowly leave the world of graphic design to focus on his passion for wakeboarding.
In 2007 he started to work during the summer seasons in cable parks in Germany and France to live his passion. He became the wakeboard vice-champion of France in 2010. After that, his new project was to create his own cable park. Which he did in 2012 by starting the company Belgium Cable Park. At the beginning of this adventure he only built a waterski lift on the 25-hectares field he had acquired.
Gradually realizing the potential that the site offered in terms of leisure activities, he teamed up with his partner Alice to create a tree climbing and a foodtruck.
Since 2015 the Dock79 has only grown with the addition of an Aquapark in 2017 and the construction of an indoor trampoline park in 2020.
