Unless you have biceps and traps like Lou Ferrigno, you're going to have to cleat, and play the tiller, as Doug said... of course to a lesser extent you can use your legs to increase/decrease the extent of your hiking.
In a serious puff you can quickly snap the mainsheet out of the cleat and sheet-out to save yourself. "Don't worry about me, save yourself..." LOL...
Yep, there's somethin' fine about flying a hull uninterrupted for 2 or 3 miles...
