Sealander – Caravan and boat in one vehicle concept

The Sealander combines mobile leisure activities with an approach that usually encompasses two separate vehicle worlds. The model is aimed at people who want to be flexible on the road and are looking for a system that can be used on land and water without additional effort. The compact design, maritime materials, and self-sufficient equipment result in a vehicle that forms its own segment apart from conventional caravan solutions.

Hybrid caravan with road and water approval

The Sealander is considered the first mass-produced model that is approved both as an unbraked caravan and as a category D motorboat. This means that the vehicle can be transferred directly from road traffic to water without any modifications. Depending on the equipment, the weight is between 550 and 600 kilograms. This means that even a small towing vehicle can move the trailer, which significantly expands its range of use. With a length of about four and a half meters and a height of around one meter ninety, the structure remains in the range of current teardrop and small caravans.

Equipment for self-sufficient use on land and water

The interior is designed so that short stays as well as tours lasting several days can be managed without external supplies. A sixty-amp battery provides power for the cool box, sink, on-board toilet, outdoor shower, and grill. Depending on temperature and usage, the supply lasts for about a week. The space follows a functional concept of compact caravan construction, but deliberately avoids overloading to allow for unrestricted switching between water and land operation.

Panoramic windows and folding top for an open-space effect

The design of the superstructure is based on principles from boat building. The folding top can be opened over two-thirds of the roof area, creating a large, open viewing area. When the sun is shining, it creates a convertible-like feeling of space, and at night, a clear view of the sky. Rain and wind can be kept out by quickly closing the soft top. In addition, panoramic windows extend across both sides for approximately one meter seventy, creating an unusually wide view that is foreign to typical caravan structures.

Boatbuilding techniques and durable materials in a compact format

The entire manufacturing process follows classic maritime techniques. The monocoque shell is constructed using a hand-layup process, a technique that few boatbuilders still use because it is time-consuming but extremely robust. Materials such as V4A stainless steel, waterproof woods, and real wood veneers characterize the structure. Teak and other woods used in the construction come from sustainable sources wherever possible. This combination ensures a long service life for the vehicle—after decades, the structure should remain stable and withstand changing humidity and temperature fluctuations without any problems.

Drive systems for different areas

On the road, the car provides all the power. On the water, the vehicle can be equipped with various outboard motors, depending on the desired range and local conditions. Combustion and electric motors can be mounted on the transom. The user decides which variant makes sense, depending on the route, frequency of use, and regional regulations. The motor can be changed without much effort, allowing the Sealander to be flexibly adapted to different types of waterways.

Target groups between caravan, boat, and compact travel format

The vehicle is primarily aimed at people who value the ability to switch easily between land and water use. Many traditional boat owners opt for the system if they want to avoid seasonal work or want to get out on the water without lengthy preparation.

Sealander compared to alternative recreational vehicles

The model differs in that it legally combines two vehicle classes. The panoramic view, the convertible-style soft top, and the high-quality materials result in a recreational vehicle that is more technologically akin to a maritime vessel. The main advantage is its ease of use without seasonal preparation.
