Could you elaborate on why this is not a method by which carbon emissions can be significantly reduced ?

This is only the second boat of a small company, they most likely don't have the ressources to get a bigger one. At this scale, the only way to make money is to move luxury products.

IMO it's a good start.

The problem is that carbon emissions come from more than just fuel. You also have to take into account the construction of the ship, the crew, loading/unloading, and pre/post-transport.

Best-case scenario, you're looking at a crew of 4 who can transport 6x350T in a year, or 525T / person-year. Meanwhile a container ship has a crew of 20, but it can carry 240.000T, and do in the ballpark of 50 transatlantic crossings a year - so 600.000T / person-year. That discrepancy is large enough that even things like per-crew-member CO2 contributions starts to become relevant.

I'm all for decarbonizing shipping, but this boat is nothing more than a rich person's plaything. It'll contribute absolutely nothing in the grand scheme of things. Maybe sail is viable, but at least put it on realistically-sized vessel like [0].

I don't really understand how the yearly tonnage per person is relevant here
