You don't need a paper chart.
A blank sheet of paper is quick and easy to do the vector sums.
Electronic plotters like OpenCPN will also do the calculations and will do them more accurately without some of the approximations and incorrect assumptions that are inherent in the simplified RYA method which can in certain (fortunately rare) cases can give answers that are significantly incorrect.
Its true you can do it on blank paper. But its easier to do it on a chart so why would you.
Show me how OPen CPN can do it over multiple hours. Maybe you are right and it has come on, but i've never seen it.
And no plotters can.
