Caterpillar Track Craft Concept

The final concept consists of a caterpillar track craft, with a maximum speed of approximately 5-6 knots in water, equivalent to a speed of 9-11 kilometers per hour. The speed on ice will be significantly higher. The concept also includes an accompanying raft, which results in a crew of two members, one that drives while the other sits in the raft and has overall responsibility for the distressed. The raft is large and has buoyancy enough for two lying persons or four seated. The craft is powered by two electric motors which drive the tracks, located along the long sides of the hull.

The concept is more of a futuristic concept, since it is based on batteries with an energy density with at least 500 Wh/kg, which according to Ny Teknik are under development. Furthermore, it is possible to use replaceable batteries, which means that existing batteries can be utilized. With replaced caterpillar tracks it is conceivable to use the craft for other purposes and terrains, such as on dirt roads. However, the concept is only at an early conceptual stage and is therefore in need of more tests and calculations to get fully operational and suitable for production.
