The measuring is done from existing boats that are traditionally built. Some are still in use, some are stored in different museums and some are left as wrecks in different places. Some of these wrecks have more or less fallen to pieces, but are reconstructed at the plan. Several boats are gone and does not exist any more.

For most of the plans a complementary sheet with information about material and dimensions are enclosed. On the plan the boat is drawn in external profile and cross-section profile at CL. In plan, each half with interior and the other half without. All ribs are drawn.

The plans are printed on coated standard paper 90g, mostly in size A1, but can be bigger (e.g. vrakeka 28 feet) or smaller. The plans are sent rolled in a paper cylinder.
