Why doese the ferry from dover to Dunkirk hug the french coast?

By staying close to the coast, the ferry avoids deeper, potentially hazardous waters and can better respond to any emergencies. Additionally, this route allows for easier access to ports and reduces travel time by taking advantage of the continental shelf. Finally, hugging the coast also provides more sheltered waters, making the crossing smoother for passengers.
