Sailing from the Netherlands to the Caribbean
In 2027, the Mariflex Challenge sets sail for an extraordinary expedition to the Caribbean. The goal is to bring together a group of motivated sailors who want to develop from coastal sailors into offshore and ocean sailors.
Ocean Challenge 2027 is an initiative by Demarage Zeil Centrum and Swelb. It is not a commercial charter trip, but a joint expedition project where adventure, training, teamwork and ocean sailing come together in a programme spanning over a year.
Taking part in Ocean Challenge 2027 involves costs. To join the ocean expedition, you are also required to complete a number of training days beforehand and reach the required sailing level. These training days come with costs as well.
The exact content of the programme and the associated costs are explained in more detail during the introduction process.
