On my islander 26 I pulled my main up by hand and would use approx. 1 - 2 twist on the winch to bring it taught. I always keep my mainsheet tight while hoisting the main. With that said even centered and tight the boom will still sway about 1 1/2 feet.
I started this process because before I ran the lines aft I was making my way back to the cockpit after raising the main one day and a power boat came out of port causing a wake that hit the boat at the same time I stepped down of the cabin top. Boat heeled, boom swung and I almost went over. From that day on my mainsheet was always tight.
