you will need to get the stringers done as the stringers and bulkheads all fit into each other!!they all have slots that correspond to one another .cant you just use your a4 printer? i did i just used printer settings to get the size i needed but mines smaller at 36" so its not like i can measure them ,in any case you need to get the shape right or they wont fit the hull shape .i think w3bby has the tiled plans for this boat and they print out the correct size without messing about with settings.if you ask him im sure he will send you them.
