I was excited to grab a ticket for this one as I missed out in 2025. Ultimately I really did enjoy my 40ish minutes on the ferry tour, however it was not what I expected at all in terms of the content and style of the storytelling. I think the poster is quite misleading... truly there was nothing to do with monsters or beasts on the tour.
The actor/storyteller/Captain of our ferry did a wonderful job, however it helped a lot to have an engaged group of audience members. I think if you end up with a quiet/shy group then this tour wouldn't work very well.
It's also a weather-dependent experience; fortunately I had my ticket for a beautiful sunny day, but I don't think it would be very fun to do this one on a cold grey day. Props for originality in using a moving vessel and I'll certainly remember this one for a while.
