Things to work on again this year

  • Tuning the rig is important. Lowers must be even so that the mast is straight going upwind and not sagging in the middle under load. We spent a lot of time tuning before the race. 
  • Rig must rock forward to make sure we get as much projection forward with the spinnaker.The tuning guides say that there should be 18” of mast tip travel fore and aft. However, there should be no inversion of the mast in the puffs. We adjusted the backstay a lot to accommodate that forward movement. Downwind backstay should be all the way to the bridle block.
  • Upwind we should have a snug boom vang. Often our vang is not even on upwind. Wrong. The tuning guides also talk of using the vang in bigger breeze to control shape rather than the mainsheet. Since we didn’t see big air on Thursday, we didn’t have the opportunity to test out that approach.
  • Kerry re-rounted the sheet leads to get us even more inboard. He thought the shape of our jib was too flat in the lower third and needed the inboard and lower attachment to give it a bit more fullness. I’ll take a look at alternate rigging solutions. If we use his approach, we may end up going to a single sheet lead block.
  • Mainsail foot shelf in that breeze (8-ish kts.) was about half max. Tuning guides talk about 1-2 inch travel between max and min on outhaul. I think we should mark the boom and keep some records.
  • On gybes he throws off the twings first (both sides) and throws the boom over first. Then he moves the pole. He throws the twings off to get the spinnaker out in front of the boat. He thinks it’s faster than our method. I tend to agree. We should practice and see.
  • On the downwind, he tended to stay up on the deck rather than get back in the cockpit. It helped him look for breeze and tactical position. Also, on the set, he reached down from the mast and undid the jib halyard and pulled on the fraculator while staying on the deck by the mast. This leads me to believe that we should re-route the fraculator so that it is next to the jib halyard so that John can stay on the port side deck and just reach down after the hoist and pull the jib down. His approach was only a bit faster than the way we do it, but it kept him on the deck so that we could gybe at any moment when we got a lane. I know that sometimes we want to gybe quickly, but we’re still bringing the jib down from in the cockpit. Again, we should do some experimenting here. A couple of boat lengths can pay big dividends here. Oh, and I happened to be in Water Avenue Coffee on Friday where Matt (Coho) works and mentioned the gybing to him. He said that on the Merit that he races on they throw the boom over first also. Just one more data point. 
  • He was not afraid to gybe. I think we had 5 gybes downwind. He didn’t want to stay close to anyone and kept looking more for breeze and lanes than making the inside so important to protect. I was fascinated by the willingness to both tack and gybe to take advantage of the breeze rather than tactically play with other folks. At one point, we were on a port-starboard with Rander and instead of waiting to lee-bow him, Kerry just said tack and stay in clear air. 
  • Our start was our problem Thursday. We had good boat speed and tactical position otherwise. The Fred approach of tacking away as soon as possible if we are in the second row is exactly what Kerry called. From this point forward, I will never again suggest sitting behind folks even for a bit. Lesson learned. Cullison has done well taking over early if they are late to the start. Oh, and BTW, I have a new piece of software I want to show you guys. I tracked that race and the software shows wind shadow. It is a big deal more than I ever thought. Again, lesson learned.
  • On the douse (windward side), Kerry didn’t care that the chute was all the way in boat. It was more important to him to get the jib sheeted in and be ready for the tack to the finish. As a sidebar, he also wasn’t crazy excited about getting the twing hardened up right away after a gybe. Sure it needed to be put on, but trimming the chute and keeping it full was more important to him. 
  • I had my weight on the cabin top upwind and Kerry went back and forth between me and Fred. We might try it with John. Having my extra 60 lbs or so forward like that may help speed. Plus, it was easier for Kerry to go back and forth and help Fred with the main. 
  • On the finish leg, Kerry kept urging Fred to scallop up to both make the mark and to give bad air to Don Hamann. That’s not new, but he was willing to tack early on what seemed to be before the starboard tack layline to gain position. As it turned out, we had to shoot the line to finish, but we did push Don to tack away and we gained a position because Don had been ahead of us at the mark rounding. Had we waited to tack, we wouldn’t have gotten Don. In other words, he was willing to take the risk of not making the finish line leeward mark (which would have required a tack at the end) just so that we could get position on Don. It’s an interesting tactical choice.
  • Also BTW, my tracking software showed that upwind we were inside the starboard tack layline the whole way up until the last tack, where we overstood the mark. If memory serves me, we had to go a little farther than we wanted because there were starboard tack boats coming down on us and we had to overstand because it was the only safe position to be in. My software also shows that we are generally pretty good on our tacks. We keep our speed up and don’t over-rotate. They take between 8 and 10 seconds to complete. Our gybes were also generally pretty good and we didn’t lose much speed. As I recall, they take about 20 seconds on average to complete. 
One other item to add to your summary is that while sheeting the jib we should try to keep the batten parallel.  This will keep it powered  up but not to tight to back wind the main and not to loose and lose some of our point.  It gives us a real starting point when trying to figure out proper trim. As you said Kerry spent some time working on the height of the fairlead and how far out on the car to achieve power in the jib.
