This pleasure boat, which had a fully licensed saloon bar, used to do return trips from the Ferry to Invergowrie Bay.
In addition, there were cruises to Perth on certain days of the month.
The timetable leaflets, from 1983, give you the lowdown on where to book and so on. You could even have your own private function on it, which sounds like fun!
However, the fun didn't last too long as somewhere between 83 & 85, the Tay Queen stopped it's cruises, and was replaced for a short while in 1985 by the Coral Star, details of which can be found in my March 2009 archive.
