I went to the Dortmund show just before the pandemic and I didn't find a show in decline at all , quite the reverse in fact , it was awesome. I even rode on the 7¼" live steam loco running freely around one of the exhibition halls which included a stretch through the large r/c vehicle display . From memory there were 8 off large halls , showing all different disciplines , all of which were to incredibly high standards . A stand out feature for me was their pro-active encouragement of youngsters , both boys and girls . In fact it was a girl who won one of the tug control contests on the boat pool ( approx 12 times the size of Blackpool Show pool ) A better idea of size may be gained from watching an 8 foot model of Bismark sailing around it on You Tube. They even had 2 large man-cooling fans for the large yacht events. The 2 full days I was in the exhibition was not enough to see everything in full detail . The trade stands included both Deans Marine and RDG amongst the large number of traders. Should anyone be interested enough I can supply information from the show guide I got whilst there . I could also forward the e-mail I've recently received for the 2024 show. As an aside , rail fare from Doncaster-Stanstead was £79 advance booking and flight Stanstead-Dortmund £53.
