The eye will do the centering for you. Line up the visual center of the bubble with the visual center of the Sun side by side. This should provide results of between +/- 2' to 4' on an Hs observation. Determining index error will be a trick. Using Polaris as per LaPook method works very well for index error determination (explanation is somewhere in the archives).
P.S. I like practicing just sitting in the passenger seat of a parked car. If your sailboat is moored in a slip then practicing from the cockpit will work pretty good.
