I in no way intended to imply that the design is no longer yours, or that I would xerox the tables from another's book to build from. Only that, by purchasing the book which is much cheaper than drawings, I would not owe further royalties. The tradeoff is that I have to draw my own forms. It shouldn't be a problem and I intend to do so next year (next boat...). I would never even consider going into production of a design without explicit permission from the designer. I think you are reasonable to request royalties for every boat built period, whether from your drawings or mine.
