I have heard of very few people in the UK building one of these paul, as the length to beam ratio is very great, and to build in any detail your model becomes very long to transport.........
However, if you visit the site link here and put in a request, I have seen a number of guys on the other side of the pond building them......some build in small scale, others build larger but split the hulls for transport.
I wish you good luck and would like to encourage you in your build, as I think they are great looking ships, especially the older lakers. and if you do start a build then help on what ever you require is always just a post away. neil.
