Airships and hydroponic farms...
you know they used to have these things called sail boats
If you look at the list of large sail boats, you'll notice they are smaller than the Pyxis Ocean, and even most of those are "sail assist". ie: They're steam or motor boats with sails as an extra thing. The aim of modern "sail" and "wind powered" boats is to go much larger than sailboats.
my opinion is those boats are too damn big
For ocean shipping, the bigger the better in terms of fuel economy and thus cost.
