For those holidaymakers who think they've seen it all, here is a coach trip with a difference.
A company AmphiCoach have built a 50-seat aqua-bus in Malta that can drive from the road into the ocean with barely a gear-change.
The brainchild of Scotsman George Smith, the aluminum vehicle can glide on fresh or seawater. The metal has a corrosion barrier and the company said the bus could withstand 3,500 hours of constant use without any adverse effects.
Clients can choose between a two or four-wheel drive on land and the specially developed engine can achieve 8 knots on water. The coach was recently put through its paces in Maraxlokk Bay, Malta.
The brightly coloured vehicles are already attracting interest, with 10 orders for the new vehicle-vessels from countries including Germany and Hungary.
Each of the vehicles costs £280,000 and Amphicoach say they can build 12 ship-shape roadsters every year.
As the pictures show, the bus is sea-worthy and customers have already paid their fare or swiped their Oyster cards for a trip into the deep blue.
The Amphicoach company claim this is the first true amphibious passenger coach, which is built under strict supervision by Lloyd's Register.
The founders, who've spent six years bringing their fishy dream to life, see a big market for tourists wanting to take the usual city bus-tour and then sail into the nearest Thames, Seine or Hudson for a riverside view.
A spokesman said: 'We have reworked and reinvented the amphibious tourist vehicle as everyone knows it. By creating a unique and exciting vehicle that is going to transform the world of city and harbour tours.
'Soon people will no longer be satisfied with just a city coach tour, they will want the complete package, a city coach tour with a water cruise built in.'
The coach has been designed to pass all E.U. legislation and is likely to become a fixture in cities over the next few years.
Just don't forget to pay your fare, as this is one bus you don't want to get chucked off.
