>Obviously, slapping a sail on a diesel powered ship straight up doesn't work. They would have done it. You need something more.
Who is they? The early days of steamships indeed had both sails and engines on the same ship.
Mostly shipmakers haven't put sails on oil-powered cargo ships because there hasn't been a strong need for it. Fuel isn't expensive enough to warrant the extra effort. But the desire to reduce CO2 emissions starts to tip the scales.
