SACS X80 ChaseBoat Design A full-size chase boat design surfaces from the Milan-based studio Federico Fiorentino. It is the SACS X80 and is designed to fulfill the role of a chaseboat. Perhaps if built it will be more than just a chaseboat because it can definitely perform multiple roles. Let's take a look at the design a bit closer. One of the first things that strike you is the sleek design profile, it looks fast even static in the renderings. In the elevated render, two distinct relaxing zones are apparent. One on the bow and the other on the aft...are sure to keep the guests onboard in a relaxed mood.
