Sorry to have started a small whirlpool by my earlier posting.
Jack is spot on to remind us about this issue. Putting on my 'paper pusher' hat, I would argue that buying building plans is not quite the same thing as buying a book. When you buy something like Ray Hasbrouck or SBAS plans you are getting two things. Firstly, you are buying a licence to build a single instance of the particular object. This is the normal way that the licence holder will earn his/her keep. At the same time you will also get a set of plans which may or may not be sufficient to enable you to build the object. These will be copyrighted which means that the author is asserting his/her ownership of the drawing. However, s/he may or may not allow the drawing to be freely circulated. There are various options open to an author, with which those of you who make use of open source software will probably be familiar. Within the steam boating fraternity my (limited) experience suggests that design owners tend to be relaxed about their drawings being copied and examined widely, but expect any builder deciding to use them to cough up the licence fee to build.
Hope that all makes sense!
In that context, can I ask if anybody knows the source of the following photos which have ended up in my 'Useful boat pictures' folder. I don't recall how I got hold of them or who owns the copyright. However, I would possibly like to use them in an article so would like permission to use them.



My guess is that it must be a steam boating colleague from South Africa, Australia or New Zealand. The garden grass is dryer than one might see in the UK and the caravan registration plate, presumably rear, is white reflective. The UK would be yellow reflective and the font is also narrower than permitted UK fonts. Any thoughts?
