Sorry, sheets. My guestimation is that you need to cut strips of my plywood sheets that are as wide as one rib + the space between ribs and glue the sheet to the keel and rails. Once you get two sheets next to each other, then you glue them to the rib with the thin CA?
I personally had great difficulty with this method so I scrapped it then went to planking then decided I liked the balsa blocks best. One thing the guys here will tell you is try to get a few rib sections with each sheet not just one.
Here's how I do it: First cut a rough plywood shape that will cover 2-3 rib bays. On the Bogue the center section is pretty flat and you can do more at a time, but it is better to get some experience before attempting big sections. Next, draw a line down the center of the piece, right where it will line up with the center keel. Using the line to align the piece on the hull, bend down each side and mark the plywood where it crosses the center of the edge ribs (the 1/4" edge). Cut to the line and check to see if it fits. I find ordinary scissors work great to trim the plywood. You want the seams between each adjacent piece to meet in the center of a rib. Don't spend too much time getting it perfect, rather leave a small gap and fill it later. Once you are satisfied that the piece fits, glue down the center to the center keel, using your line to get it straight. Once that joint is cured, bend each side down and glue it to the ribs. I tend to use medium CA for the whole job -- I hit the ribs with glue, bend the piece down and then hit the piece with CA accelerator. I just hold it in place until it cures, usually just a few seconds. You can also clamp the piece down and wick thin CA between the pieces and follow it up with some medium CA for reinforcement. All the methods I've seen to make the bottom of the hull tend to be tedious - pick your poison and get it done. You can always try a different method next time.
