This probably just seems like a trivial little thing, but I'd just like to bring up the awkwardness I sometimes feel with using the "Museum Ships" category, as there are numerous vessels I've encountered that are vintage, and a no longer in active service, yet would not be considered to be a museum vessel by any means. I really feel that instead a more appropriate category might be for "Preserved Vessels" that would encompass conversions of classic vessels to yachts, charters, or liveaboards, where they are still kept intact, but are generally not publicly accessible.
Does anyone else have any thoughts?
