The Sealander caravan, according to the manufacturer, functions as a caravan on land and as a motorboat on water. On land it is towed by a passenger car, while on water it is controlled by an outboard motor. To launch, the caravan is reversed to a slipway and rolled into the water. The hull is made of glassfibre-reinforced plastic, and the interior has two benches and an adjustable table. On land it seats up to six people and converts into a sleeping area for two; as a category D boat it is intended for lakes, narrow rivers and canals.
