I have my Dad's 1941 copy of the Popular Mechanics book Build a Boat for Fun or Profit
. It describes installing canvas on a Sailing Dinghy
of that period'
"After the plywood
has been given two or three coats of paint, and this has dried thoroughly you cover the entire deck
, including the cockpit
with a piece of No. 10 duck canvas. Stretch the canvas over the deck. copper tacking it along the gunwales and transom, afterwhich the edge of the canvas is covered by a rub rail. Next, walk on the canvas over the cockpit
which removes the slack before tacking the edge of the cockpit.
It says the canvas is then painted but doesn't mention any details on that.
There are a couple of sketches on the process if you like a scan of them let me know and I'll email
them to you
