Finally, in marking out the sides, it's particularly useful to draw a line showing where the bulkheads (of frames) are meant to go on the sides. These are the vertical lines that about a quarter of the way aft from the bows and a quarter of the way forward from the stern – that is, 'b' to 'i' and 'd' to 'g'.
Finally, even with a tiny boat like this, before cutting out it's a really good idea to label each plywood part to be cut out – 'bows transom', 'stern transom', 'side', 'bottom', 'fore-deck' and 'aft-deck'.

For most of us, the big issue in cutting panels drawn on a four by eight foot sheet of plywood is how to hold such a big piece of thin material steady so that it can be cut smoothly and pleasantly without wobbling and binding in every direction. The ideal thing would be to have two workbenches placed close together so that you could cut your material in the space between them, but few of us have one workbench, let alone two.
Instead, try to find a collection of objects of the same height - about a foot can be enough, even if you're using a jacksaw – but don't choose a workspace where damage to the floor could be a problem. The props should preferably made of plastic or wood so that your saw won't be ruined when you inevitably hit them one or other of them - and for the same reason they should not be too precious.
When you're sure everything's ready and steady, start cutting... Start with the long cuts, and always work along the waste-wood side of the line, taking care to leaving a minimum of space between the line and the saw, but always without cutting into the precious work side – for you can always cut a bit more off.
Even working with a handsaw, there's no need to hurry, for you do not want to make a mistake that could lead to having to buy another piece of timber.
