Jezza, have you considered contacting Dumas for a set of plans? Just don't tell them that their wood is "garbage". It is, but you really want to be polite. Another option would be to get a set of Roger Newton's plans for the boat you are building. Roger's plans are quite complete and include the scale color scheme as well.

Sure is nice to converse with builders for a change. ARF airplanes and ready to run boats turn me off!
