2,5 mtrs draft
will be a real challenge. It is on the edge of what' s possible and practical.
In spite of what people think, the inland waterways are quite shallow, at least in Holland
It means that you have to follow the mid-riverbed and the pro-skippers with their 1200+ gross tons barges will definitely blow you out of the water
. Their draft
is same and they like to maintain their speed at a level of 10 knots +. In theory everything is possible but with a draft of 2.50 mtr you are looking for the extreme.
Experience in this case is wisdom that comes too late.
Concerning the inland waterways of Holland
I can help you out. I can even help you planning a route
. Regarding Main-Donau and Donau river you should confer with the pro-skippers traveling that route. The maximal draft for Rhine and Donau is about 3.00 mtrs, depending on waterlevel. This year, waterlevel is below normal.
The boat of Jack van Ommen did not have the draft of your vessel and according to my knowledge the Main-Donau connection is the bottleneck in your scheme.
