"I found that you don't need a full gale to sail under bare poles. You can do it, even in moderate winds. Also, under favorable circumstances (especially in smooth water), you can even tack to windward to a certain extent, although it obviously takes patience"
Sailormon, you've piqued my interest with this one. How do I tack to windward with bare poles? I'm a *"Motor? We don't need no stinkin' motor!"* kind of guy, but even so hadn't considered the above possible. From what do you get the kind of lift to take you upwind? The mast? the hull shape?
