German company Sealander has introduced a trailer that can be used both on the road and on the water. The trailer, measuring 469 cm in length, 166 cm in width, and 193 cm in height, has a gross weight of 750 kg and is certified CE category D, allowing it to navigate lakes and calm rivers in winds up to 4 Beaufort and waves up to 0.3 meters. The hull is made of fiberglass-reinforced plastic with a double floor and gelcoat, and the chassis is galvanized. On water, the Sealander is powered by an outboard motor of 5–10 hp, reaching speeds up to 10 km/h. Inside, there are two benches that convert into a bed measuring 205×151 cm, with options including a kitchen, sink, refrigerator, audio system, solar panels, grill, toilet, and shower. The base price in Germany is 39,750 euros, with options potentially adding 12,000 euros.
