People smuggling gangs are resorting to "mega-dinghies" to transport migrants across the English Channel as a crackdown by UK and French authorities limits the supply of smaller vessels. This new tactic, involving larger inflatable boats capable of carrying hundreds of people, has emerged as gangs face increasing frustration and reduced opportunities for crossing.

The shift to larger, potentially more dangerous vessels comes amid increased police presence on French coasts and claims that French officers are intercepting two-thirds of small boats before they can depart. This has made it harder for smuggling operations to acquire smaller boats, forcing criminal groups to collaborate and use fewer, larger vessels.

A BBC investigation observed groups of migrants boarding an inflatable dinghy on a beach in northern France. Gang members have indicated to sources that more "mega-dinghies" are being prepared, raising concerns among emergency services on both sides of the Channel due to the heightened risk to human life. The image of a 15-metre boat carrying 230 migrants towards the UK recently drew widespread condemnation.

This change in strategy also reflects a significant price increase for migrants. Smugglers are now quoting up to €2,000 (£1,700) per person, a substantial rise from around €1,300 a year ago. Payments are also increasingly demanded in cash to ensure migrant commitment.

On August 4, 170 people had to be rescued after their vessel caught fire mid-Channel, highlighting the perils associated with these crossings. The limited availability of small boats means fewer crossing opportunities, driving up costs and pushing smugglers towards riskier methods.

French police have reportedly intercepted a greater proportion of boats, prompting smugglers to adapt. The BBC witnessed a departure where migrants, equipped with orange life jackets, boarded a boat that had set off from Belgium, indicating a need to travel greater distances to evade detection.

UK and French ministers are reportedly discussing measures to bolster police numbers on the French coast. This initiative comes as French President Emmanuel Macron is expected to visit Downing Street.

The increased reliance on "mega-dinghies" poses significant challenges for rescue services, as these larger vessels carry more people, potentially leading to more severe incidents if they encounter difficulties at sea.
