Spot Cool Stuff has it on their list of 5 cool camping caravan trailers. It’s the Sealander Aquatic, the trailer that can be used as a camper on land and a boat on a lake. That thanks to it’s 5hp outboard motor and the amphibious frame and chassis. The interior is large enough for two beds, a kitchenette and a cooling & heating system, all of which are removable if you want to make room for more passengers. €15,000
It’s perfect for reenacting scenes from The Abyss, and also for getting some of the thrill of scuba diving without the safety risk or need for lessons. After 10 minutes of simple instruction you can be bobbing around beneath the waves in a HydroBOB, a device that’s like an underwater scooter with a viewing bubble attached to it.
It’s like a cross between Wonder Woman’s invisible jet and Inspector Gadget’s foldable car. The Transparent Kayak is made of a clear military grade urethane that makes the entire hull see-through—very cool for both navigating shallow waters and spotting fish. The Transparent Kayak also weighs a mere 26 pounds (12kg) and folds up to a size small enough to fit into a large hiking backpack, allowing you to carry your cool watercraft to rivers and lakes that aren’t directly accessible by car.
The same company also makes a transparent canoe.
