Posting on Facebook that my tugboat Mohan is very loosely based on the BRatttug, I was surprised my comment was followed Ron Burchatt who designed the prototype!
This was then followed by a post with a link to this video showing the vessel in action at the Vancouver boat show.
OK, it's not very exciting after a while, but we can see just how manoeuvrable this boat is. We can also see it's shorter and wider than my model, but that's OK. However, if Ron produces an accurate kit, I could see it being very popular in model form.
