In German, a “Jolltau” is a simple tackle used on board. It stands for a centuries-old principle of seafaring: make clever use of the means at hand, redirect their force and make them even more useful. That is exactly what we do with your boat's data.
Jolltau is made by working professionals from the boating industry on the Bay of Lübeck. We develop Jolltau from everyday practice on the water.
