These credits have been offered to you with pleasure, spend them with pleasure!
It's your "starting bonus"
Before you set sail, you'll have to prepare your boat. These credits will allow you to choose the equipment you'll need to sail on the race or leg in which you'll take part.
They will also be used to obtain maps that enable you to use the various navigation tools available in the game.
Spend them without counting! If you have any credits left when you cross the finish line, they will disappear!
