I think Greg Rossel demystifies the process best in his book, Building Small Boats.

Vaitses' book demystifies and allows for lofting anything, not just certain boats.

Did you take Algebra in High School? If so, then you learned about plotting data on an X/Y chart - that's lofting!

To be clear, there is plotting the points and then there is fairing the lines.

When the designer creates the table of offsets he may induce errors, either by a typo (2 ' instead of 2") or by an inaccurate measurement. You then plot these numbers and will (not just you, everyone does) introduce more errors in the putting the dots on the plywood.

Fairing comprises 80% of the lofting effort. It involves finding and correcting those errors. The lofting references will explain how.

^ and then, when the errors are sorted and the lines are fair, you can use the lofting to pick up the bevels for sawn frames and transom, and to create templates for the rebate, and apron /stem bevelling, and so on.
