Hey! Just somethings I've learned from sailing the J70 and from watching the video. You guys need more rig tension your forestay is sagging which is a indicator to put on more backstay or turns onto the rig. Try to pinch up into the wind more what will make the main trimmers job a lot easier. In breeze like this I have the first 3 inches or more backwinded in my jib. Snug up your vang going upwind so you boom doesn't lift and powers up the main and then it will spill the air. We normally don't ease our mainsail that much going upwind we would have ours, traveler middle and mainsheet mostly in this helps reduce flogging the main and make you go into the higher mode. The helm should drive down almost dead downwind as the kite is going up what will make getting the pole out and spinnaker up so much easier since it is hidden behind the main. (Be careful of waves if you go dead down wind) On the gybes it is very important to keep the apparent wind up or you will wipe out you gybed at less then 6 knots when your main switches sides the wind will catch up and you will wipe out. A big part of losing speed on that gybe was getting stuck in a wave what slowed you down. I'm no pro but these are just things I've been told by pros so hope this helps!
was thinking all of these as I watched. sailed the SB20 for a couple of years and the 70 is very similar to it. Now mostly race the J80s which feel like a comfort boat in comparison to the 70 and the SB
