Just like its twin Sior Todaro, the grand touring motorboat Sior Marco is one of the most important vessels of the Ducale fleet. Measuring more than 21 meters in length, with an elegant and tapered shape, it can comfortably accommodate 100 people, all with reserved and covered seating. Made entirely of wood, it has been navigating the lagoon’s waterways for over 25 years, always maintained perfectly efficient and reliable by the men working in our shipyard.
