That's a stupid argument, sail boats are not practical in the world we live in today. Their use in the past doesn't matter, because that world no longer exists.

Absurd amounts of material and food are moved quickly and safely by modern shipping , sail boats are not capable of this.

If sail boats were practical then somebody would be using them already.

Yes I have been, they are wildly impractical for real international travel

Sail boats are a bag of shit

What have you done that's actual made a difference?
