I take your point, TB, but the problem is, it seems to me, that liners are large. Yoiu've only got to look at the RoG 1/400 Queen Mary 2 to see that, and there are now sevral cruise ships of similar size, either in service or projected.
Tooling up for such a kit requires considerable outlay, to be repaid over a number of decades. Hence, large-scale ship kits tend to be of iconic vessels, often national symbols of the country in which they were built. Hence Airfix producing the Queen Elizabeth, QE2, Mauretania and Canberra in the 1960s. All iconic ships and national symbols. One thing about modern cruise ships is that few of them have any history to them, another thing that attracts modellers, and which is more often associated with warships.
That said, it does seem odd that Heller never did a kit of the France or the Normandie in 1/400 (or any other scale, for that matter). Maybe it was because the size of the hull halves would have been towards the limit of what was achievable in injection-moulded plastic, back when they weere expanding their ship range in the 1960s and 70s.
One possibility - maybe the more family-friendly cruise lines, such as NCL and Royal Carribean - could commission kits of some of their ships to be sold in their gift shops, like Shaw Saville did of Airfix all those years ago. There again, they'd probably be more likely to be small-scale efforts, partly because of kids' short cocnetration spans, and partly because of the practicalities of getting, say, a 1/350 Ventura back home on the plane at the end of the cruise.
Maybe we should campaign for RoG to do a 1/350 Bremen or Europa, complete with nude sunbathing decks and then get White Ensign or GMM to do an etched set for it, complete, of course, with passenger figures!
Cheers,
Chris.
