It is worth noting that rigging and sails for lightweight racing hulls has evolved way beyond anything that has ever been used commercially -- And would look quite weird (though still recognizable) to a 19th C sailor [0]. Also, the material science involved in creating laminated sailcloth is very close to state-of-the-art. Of course, racing yachts go fast because they weigh very little. Also, Kitesails [1] have been proposed many times over the last few decades, but I've not heard of anyone using one commercially.
