We rented one of the boats for a day at the weekend. The ship was very new and the day unforgettable! Right from the start we received very good advice and were supported in planning the route. The landlords were incredibly nice, helpful and always there for us. The "Invictus" was super motorized and yet economical. With the music system on board, we were able to accompany the journey via Bluetooth. Definitely the most likeable and best charter company on Lake Constance and highly recommended!
