Official data from the Government have indicated a skyrocketing number of small-boat arrivals.
In 2018, just 299 individuals made the dangerous journey.
Since then, when tracking began, the total number of small-boat crossings reached a historic high of 200,000 migrants.
People smugglers have also begun deploying new tactics to evade the wrath of border officials.
Hundreds of small boat migrants set sail for Britain over a massive stretch of French and Belgian coastline to avoid police beach patrols

At the start of May, the People's Channel revealed hundreds of small boat migrants set sail for Britain over a massive stretch of French and Belgian coastline to avoid police beach patrols.
A senior maritime source told the People's Channel: "People smugglers pushed off boats from well into Belgium, all the way down to a beach at Treport, south of the Somme.
"That's almost 100 miles of coastline the criminal gangs are using for launches on the same day.
"It's an obvious effort to avoid the beach patrols, which are normally concentrated around the Dunkirk and Calais areas."
