there are a number of tactics you can use beyond those above.
for long trips, going slightly in the wrong direction to catch just the tip of the wind and correcting the heading later when it shifts works wonders; its like tacking only across the longer haul and a bit more lazy.
for short trips, moder power.
as often as not, actually more often, just paddling the karve straight line is not too shabby assuming the wind will change eventually.
you can also explore... head whatever direction the wind sends you and head back home the long way.
