San Zulian is one of the bigger grand touring motorboats of the Ducale fleet and, like its brothers, it is built entirely with wood. With almost 23 meters in length and more than 4 meters in width it can accommodate 100 passengers, all with their own seating, in a wide and covered cabin divided between two sections at the prow and bow.
Just like the Sior Enrico, also the San Zulian offers seating for people with disabilities. The safety equipment maintains the highest standards in accordance with regulation.
