- The sun deck, that is partly covered and has plenty of deckchairs and hammocks for relaxing on.
- The upper deck is the Bridge Deck as well as 4 passenger cabins, the restaurant, bar and library.
- The main deck has 8 passenger cabins, galley and crew quarters.
There is also a swimming platform off the stern, perfect for those refreshing jumps into the river. The vessel is equipped with 3 motorised canoes for daily excursions.
