I’d look at the group size first, then decide how much time you actually want on the water. Once those two things are clear, the boat type becomes easier to compare. A sailing catamaran can make sense if you want a more relaxed day, while a motor yacht might suit a tighter route with several stops. I’d also check whether a skipper is available before getting too attached to a particular boat, especially if nobody in the group wants to deal with navigation.
