Itinerary advice for a luxury catamaran Croatia trip (Split to Dubrovnik)?

[GreatB]

Greetings! A group of us (my wife and I, plus three other couples) are currently in the early stages of planning a big group trip to the Dalmatian Coast for next September. We usually just rent a large villa somewhere and do daily excursions, but this time we want to try something completely different and spend the week on the water. Because a few people in our group get a bit motion sick, we want maximum stability and comfort. I was doing some research and we are heavily leaning towards booking a luxury catamaran Croatia through a specialized boutique agency I found online. The idea of having a massive floating lounge area and a dedicated local crew handling all the navigation and cooking sounds like the perfect stress-free vacation. Before we lock down the dates and the specific boat, I have a quick question about the route. If we do a standard 7-day charter starting in Split and ending in Dubrovnik, is that enough time to comfortably see Hvar, Vis, and Korcula? We really don't want to feel rushed or spend 6 hours a day motoring. Would love to hear from anyone who has done this specific route on a multihull!
