I wouldn’t say easier, just different. The main reason we have soft sails is because they are much, much easier to handle, get up and down, reef, and store, but it is a considerable compromise from the pure foil shape, like a rudder, keel, or airplane wing. The efficiency is as much as 80 percent better, but you’re still faced with determining the right amount of area. In theory, you need less area for a specific wind speed with a hard wing, compared to a conventional setup. But on the other hand, you want to have more area in light air, and for downwind sailing, which means you’re overpowered when the wind increases. So, you still have the same old problem of controlling the shapes. With soft sails, this comes with mast bend and sail shape, which is a bit more complicated to model properly than the twisting flap elements on a hard wing.
