There were a couple of articles in Classic Boat a few years ago about building one of these fine tenders - I have got them somewhere, will try and find them, and if I do, I'll scan them and email them to you, if you would like copies.
Charlie, I found the articles about Jim Hazel's dinghy - I had torn them out of the magazine, and filed them away safely.... hence why they were so difficult to find...... there are 6 pages, probably about 150 kbs each when scanned, hence a total of about 900 kb.
If you PM me your email address, I will send them to you no worries.
And if anybody else would like a copy, please do scribble me a note. She is a very fine little tender indeed.
