The Hull 1 Rib Plans as only one half (right hand side only) that will print on an A4 printer
Including a segmented keel so that it will also print on an A4 printer
All the ribs are symmetrical so you can use these drawings for both sides.

Don't forget the holes for the prop shafts, I would suggest making the prop shafts first or at least getting the outer tube so you know what size it is, to get the hole size right, even though I drilled the right size holes I ended up cutting some teeth in the end of an extra piece of prop shaft tube with a file and using it as a long "drill" to get rid of some glue in the holes and to cut through the hull skin from the inside. Because the construction stringers bent slightly, so did the path of the prop shaft holes!
