What kind of boat are we talking about here? Most beach cat masts can be raised by hand. All you need to do is tie a line to the forestay, run it through the bridle, and bring it to the tramp. Raise the mast, hold it uprght against the shrouds with one hand, reach down and grab the line with the other. Tie it tight on a mast cleat. Go to the bridle, connect your forestay to the bridle, and remove the line.

Just make sure you use a strong enough line...
