The brainchild of German designer Daniel Straub is designed for those who like living life in the slow lane, with the 380kg vehicle cruising at speeds of up to 5.6mph on water.
The 33-year-old start-up entrepreneur had relaxation in mind when he created the Sealander, which can be towed along by a car to an ideal spot for boating.
With its fitted benches and tabletop, the electric-motor powered vehicle allows caravaners to enjoy a picnic on the water.
The seating area can be converted into a bed, and the removable roof allows users to soak up the sun.
Daniel, from Kiel in Germany, dreamed-up the idea while studying industrial design.
He began building the vehicles in 2010 and sold his first one just a year later.
Since then he has made around 30 of the caravans.
Daniel said: "The Sealander gives you the option to push boundaries. Its flexibility makes it possible for you to do whatever you want to do, whenever you want to. A kind of freedom."
His creation is handmade out of a single piece of glass-fibre-reinforced plastic, and the basic model costs roughly £12,700.
Additional costs are incurred when customers choose from different packages.
The 'Elektronic' option costs roughly £890 and comes with additional lighting and a charger for the on-board battery.
The more luxurious ‘Living’ package costs roughly £826 and gives the vehicle a more homely feel - with curtains for the front and side windows, along with a complete cushion-set.
