Just did some napkin math on this, just the carbon footprint of the crew for this ship nets out to almost the total carbon footprint of 16.14g-co2/ton/km for container shipping..

Take the average person's footprint of 7co2-ton/yr, math that out with the 80 ton cargo capacity, the short daily distances ~250km/day, 14 crew, and you come out with about 12g-co2/ton/km just for crew for these schooners. easy to see another 4g-co2/ton/km being in just upkeep for a vessel of wood and canvass. So yeah if someone wants to virtue-signal, then go for it ship your stuff this way but don't think you are actually netting out a smaller carbon footprint then a container ship here.

You can probably add some extra also from it not being standard container ship so loading and unloading it is likely to be less efficient than containers.
