Some 30 people were rescued yesterday after a blaze tore through an amphibious tourist boat opposite the Houses of Parliament.

Flames ripped through the London Duck Tours vessel on a stretch of the River Thames close to Lambeth Bridge.

Many of those on board leapt into the water as flames took hold and thick black smoke billowed from the burning boat.

Passengers were later hauled to safety by rescue workers and crews on passing tour barges. A woman and a child were taken to hospital with suspected smoke inhalation while further tourists were treated at the riverside. A police source said the nature of the injuries “could have been a lot worse”.

Some 28 tourists and two members of crew were on yesterday’s stricken tour.

London Duck Tours promise to offer an adventure on both road and river

London Fire Brigade (LFB) said the beleaguered craft was 33 per cent damaged by the fire which broke out shortly before midday.

LFB said it pulled 30 people from the water and had the blaze under control by 12.10pm. Group manager Neil Withers said: “A number of people jumped into the water but they were soon rescued, and fortunately at this stage it doesn’t look like anyone’s been seriously injured. People are clearly cold, wet and in shock but they were pulled from the water really quickly and that’s testament to the work of our firefighters, other emergency rescue teams and others who rushed to the scene to help.”

The casualties – all tourists – were warmed with cups of tea on the banks of the Thames.

London Duck Tours touts itself as the “antidote to the usual bus tours” and promises to offer families an “adventure on both road and river”.

The yellow boats – known as ducks – are said to offer a “much more exciting way to see the capital’s landmarks when compared to a London sightseeing bus or cruise”.

The firm’s website states: “No river cruise in London gives you the excitement of leaving the road and entering the Thames in such dramatic fashion and no river Thames boat cruise is as quirky as a London Duck Tour.”

Tours last around an hour and a quarter, with around 30 minutes spent on the river. They are advertised as the “perfect activity for couples, families, friends or if you’re looking for things to do in London for kids”.

According to the company, each boat is modified to meet “stringent” safety regulations set by road and river authorities. Each vehicle seats 30 passengers, has a public address system and is said to be fitted with full safety equipment.

Trips depart from Chicheley Street, near the London Eye, before the amphibious vehicles launch from a slipway by the MI6 headquarters.

According to London Duck Tours, the craft used for the “splashdown” were originally used for the D-Day landings in 1944.

LFB said six fire engines battled yesterday’s blaze, alongside two fire rescue units and its fire boat. Children as young as six were scooped from the water following the blaze.

LFB station manager Simon Tuhill said a third person was taken to hospital following the rescue operation. The man was said to have suffered a minor head injury.
