The hose is really extremely massive. On the outside it is not wavy but smooth with textile structure. I ordered it as a tank filler hose for the sailboat tank. In the place he will probably do the next hundred years. A lighter version would have done it for me as well. In any case, use the heavy hose clamps.
Certainly useful for commercial ships and large sports boats, but much too stiff for smaller sports boats and therefore very difficult to work with. If you're unlucky, processing isn't possible at all, but you only notice something like that when it's too late.
