But I can understand your point. Timo could you please list some (let's say 3-4) examples where you think they ought to have mentioned/used the yacht?
Tangental, but related: there's a blanket category of evidence against Voyager's aeroshuttle in the case of the Delta Flyer; this is a craft built from scratch to accomplish what the aeroshuttle should have been designed to do from the get go; indeed, the mission into that gas giant is the ONLY kind of mission you would ever need an aeroshuttle for, and if it was so ill-suited to the task they could have easily modified and enhanced it for that task instead of building a whole new ship from scratch. Conversely, if the shuttle was so badly damaged that they couldn't even use it (nothing on the USS Voyager was ever THAT badly damaged) they could have simply ejected and scrapped it and put the Delta Flyer into that saucer slot.
Two series' in a row where every single time a "captain's yacht" or similar craft ought to be used, they pick something else instead.
