DOCAT 3500AR  

The DOCAT 3500AR is our first total solution and was made on demand of Dolderman. Dolderman has exclusivity on the DOCAT 3500AR package in the area of inland waterway shipping in Europe. ArenaRed is looking for dealers who are interested to sell the DOCAT 3500AR package in other markets or other countries outside Europe.
