Ok- just kidding. Lots of ways to do it, but I believe the preferred method (for me and most of my rafting crew) for a fully load raft, at flows below 10K or so, is to start center right as you exit the slack water and start to get carried by the current. The reason why you start center is due to either a fence of rocks on the left, or a lateral wave caused by it that will carry you into the main current and right into Skull.
I like to have my angle at about 45 degrees from center, bow forward. Then I start pulling towards the left shore at a 45+ degree ferry angle until I'm sure I have enough speed to get around Skull Rock.
So then you're in the left side current, still facing downstream, and you can negotiate the boulders in the left channel & can shuttle your oars if you get too far left. Of course, if you go too far left you can bounce off the left rocks and spin into Skull, or not pull hard enough and go into Skull.
Full disclosure: I have missed my timing and flipped a loaded cat using this method. I've also inadvertently gutted it and been fine. But given the estimate # of times I've rowed WW, I'd say this method has been 97% effective for me.
But others will of course have their methods too. I've also run the far right line, and that's easier to make but there are holes to punch leading into them, especially in bigger boats. If the flows are still above 10K in late June (probable), you can line up center-left and push (forward) a left angle - the left lateral wave is mostly washed and the left channel is cleaner.
