It doesn't really make sense to compare a 350T sail boat with a super tanker, a comparable diesel boat produce 36g per ton per km(according to the same report), the "grain de sail II" aims to replace those, and the gains are huge.

Well that comparision is what we were doing here.

There are market niches for many things that target things that are impractical for various reasons. There is nothing wrong with that.
