James,
would you “Adam and Eve” the boss just went to the shops for milk; I nipped up to look; you are in luck I have the very set of plans (1 sheet, two sides) as mentioned by Dave M above (581). If you want them sending, contact me by e. with your address – no charge – I’ll send them in a tube acceptable to your PO as well.
I’m an AMBO member and am building my second barge, Lady Daphne, from scratch from plans supplied by Brown, Ferguson and ? of Glasgow, drawn up by H Underhill.
My first barge was “Celia Jane” by Metcalf.
Kimosubby Shipyards.
The atavar is the “Theresa Mary” (the Celia Jane renamed after the Boss!)
