Good execution of the 1-3 Passback around the first two legs of the box drill. On the upwind passback, Max (crewing in boat 2) does a number of things well, from hiking to keep the boat dead flat while pining boat 8 (its always critical to be dead flat in windward leward situations so you don't slide sideways) to "slithering" in through the lulls. When Boat 2 tacks, Max leaves the jib eased on the flatten, showing great Course Awareness that they are past lay-line for Mark 1, and giving Connor the acceleration to break overlap and get Mark Room on the Toppas (boat 8).
On the reach leg, we see the 3rd boat do a good job of pushing high - the one leg where we do this! This created separation with the 2nd boat, and allows you to either roll them (this is what happens in the video), or "whip and dip" where the crew hikes out, turns the boat aggressively down to a broad reach, and ducks to leeward of the 2.
Study Question: What can the 2nd boat (who is facing a 2 vs 1) do differently to slow down the passback?
