So in motor boats everyone huddles back around the stern whenever they get on a plane? I can see moving weight aft to lift the bow and get the boat moving, but for the crew to have to huddle that way on a boat as expensive as this one in conditions that aren’t overly boisterous (they’re not reefed) speaks to a design problem. Maybe they should rig racks off the transom to hike from? Could use them for dinghy davits when they’re not racing.
To balance upwind and downwind performance, the CS has a rather fine entry. If you want a downwind only boat, you build a scow-bow. In the opening shot they are on a seriously tight spin reach are are WAY loaded up. That's where I'd have my crew weight in that situation.
