Canal des Pangalanes

Hi travelers

I plan a trip by boat Mananjari to Ambohitsara and back (Pangalanes Canal). Has anyone done this? I need a tour operator to organise the boat-trip, stay in Ambohitsara 2 nights. I would prefer a motorised pirogue boot and not a speed boat which cost me approx. € 300.- Who has advice or address? Thanks for your help.
