Be aware that the diagram provided by Escapade is very basic indeed, and that there are other measurements needed which will more comprehensively determine the shape of your sails.
When I had a new main sail a few years ago, I approached Kemp Sails in the UK and downloaded one of their sets of diagram and measurement instructions. Amongst other details not shown in the diagram above, it also also took into account mast bend with tension on the back stay. There were several other points too, so you need to ensure that the instructions and diagrams you download from the sailmaker of your choice are specific for your boat rig.
