  1. S9 Turbo test - round two (5 hours!). Wind 4mph-14mph, gusty, shifty - South to ESE, nasty boat chop. Light shifty air, light boat, bad chop - not ideal. Moved the jib down, directly shackled to the pole. Improved jib sheeting system - 4:1, small line, low drag. Opened up jib traveler - normal position now about two inches from max travel. No more choking. New systems eliminated jib luff slatting - adequate tension now easy to achieve. Our local Yacht Club RC graciously allowed me to race with the Board Boats as long as I didn't interfere with the racers - thank you Fred! First two races were low wind, shifty, bad boat chop. I kept the foils in foiling mode - max drag. Mistake. Like sailing with the brakes on. Embarrassing. Third race I disconnected the flaps, released tension on the wands and sailed it like a floater. Quite a difference - much better result. Looks like determining when to go to floating vs foiling mode will be important in light air races. We'll see. My 2 cents: in light air - floating mode only. In medium and heavy air: floating mode upwind, foiling down. Blowing like stink: skimming upwind, foiling down. Upwind foiling just does not work for me - a heavier skipper may have a different result. I give up too much angle to get it foiling. Ok, play time after the races - wind now abut 14 mph, a lot steadier. Jib offers a lot more power. When it grabs there is quite an acceleration. Have to run less rotation on the main to keep spreaders out of the jib. Upwind foiling easier - but without a rabbit boat hard to tell if that is good. Downwind: ok, jib now great. Jib sheet and traveler limits can be adjusted, At my max release on both, jib draws great, gives proper indications and works well with the main. No jib adjustments required downwind. Easier work load - sail to the jib telltales. Downwind foiling only requires gentle steering, not fighting it like in first video. In the lulls the jib seems to pull through a little longer than with main alone. More power through the gybes, tacking much easier. Helm: heavier at speed than with main alone. Slight and unpredictable tendency for fully neutral helm upwind. Don't let go the stick! Overall the jib adds complexity and power. Beginners should stick to main only - pretty sweet ride in good wind. Would be interested if there is anything here to compare with your experience. Speak up, please. No video today. Will try again on Tuesday - my 64th birthday! Fair winds, Charlie
  2. ACS: Thank you for your comments. It's nice to know somebody watches with a critical eye. That's what I hope for. It looks to me like you aren't doing anything with mast rotation. Downwind, i understand it being fully off but it seems to me that upwind, it is also fully off and I suspect you will get higher speeds with less rotation. Yes, the crew did not pull the rotation back for the upwind leg. Hard to find good crew. I guess the sitting in vs trapezing and going for it are personal choices. I would imagine that sitting in is significantly slower but less likely to end in a mess, although if you did stuff the nose in, there would be so much more to hurt yourself on as you pitch forward. It looks like the jib isn't doing anything worthwhile. If i understand you correctly, going for it leads to not only faster speeds but because the apparent goes forward, you end up sailing lower as well. This is what I would expect. Using the trap downwind is not difficult - it's the re-boarding that is tricky. Downwind, at speed, the helm is very sensitive. My number one goal when sailing alone is to stay on the boat. In the last video I was out there alone - no chase boat. If the helm wiggles while I am coming in off the trap I'll be off in a flash. Don't ask me how I know this. Yes, sailing too low negates the jib, as you noticed. Might as well not have it when sailing that low. Sitting while foiling downwind was a bit unnerving at first. Every time those short little bows started down I thought I was gone. After the first couple of runs I learned to trust the boat - as the bows dip, the wand commands more "up" on the main foils, and all ends well. I don't think would happen without the wands. I'll get more practice downwind on the wire - but only with backup of some sort, for now anyway. I am slightly puzzled about the balance of the boat, particularly upwind. It would seem strange fo the boat to feel good either with or without jib, so are you changing anything, such as mast rake, to balance the boat for the different rigs. Boat feels pretty conventional upwind with the unirig, especially in high mode. This was my first time out with the jib. Really different. Need more time on the water to figure it out. Need to tension jib halyard more - sail would flop if I went high at speed. Seems to me the jib pulled the boat down, especially in the gusts. Slot too tight? Don't know yet. Only change I made so far was on the rudder rake, and that may have been the wrong thing to do. It would be good if we get by with no rig changes. The big question is whether the improvements are due to the extra area or the aero advantages of a jib. This might become clearer as you compare performance in different wind conditions. Agree completely. ACS, again, thank you for your observations, please continue. Charlie
  3. ACS, good feedback, thank you, let me sleep on it. Charlie
  4. Thank you Doug - comments please?
  5. Thank you Waynemarlow. Grin factor intact - never bored. Challenged, perplexed, surprised, even scared, but never bored.
  6. https://www.youtube.com/watch?v=QrHXOul-YnQ I think the link above will take you to the S9Turbo test from Friday. Please let me know if the link works - or not. Extra power upwind was impressive. Still difficult to make good vmg while foiling upwind. Tried sitting downwind and going as low as I could and still foil - probably much too low for the jib to make much difference. Did have to change rudder rake. John prefers trapping downwind - lower and faster. Still some rigging and fine tuning to do - will have pics soon. Thank you, Charlie
  7. W: Max lift on the flap can be locked in by leaving the Teleflex hooked up and the wands stowed - easy to do but max drag also. Will try that just to see what happens - but not in a big blow. I'll try to find a way to freeze the bellcrank at the top of the board. Charlie
  8. Hey Martin: next time you take out your Whisper would you disconnect the mechanism? It would be interesting to see if my results could be verified or invalidated. Thank you!
  9. "free" T foil test on S9T: Wind 10-14 mph, gusty, shifty, very light chop. Did a routine foil upwind and down, then disabled the Teleflex connection to the main foils and lifted the wands to "stow" position. Main foils were left in foiling aoa position for these conditions, which is max lift. Flap was free to find its own happiness - which is neutral when not moving. It does have a fairly substantial tendency to remain in that neutral position. Mechanism didn't move much while under way - an indication the flap wasn't moving much. Upwind the boat changed from a lively, dynamic ride to a standard beach-cat feel. Speed and angle were better than I expected -- there is a large area of rudder + board in the water - especially for a boat less than 14 feet long. No tendency to fly, even when weight was fully back. Best feel and speed was with weight centered around main foil - just behind the shroud. Boat speed 10-12 mph - would be "skimming" upwind with foils down. Well behaved boat - no surprises. Downwind again felt like a standard beach cat - no thrills here. Test foil showed 18-21 mph boat speed downwind with a quite lively ride, best on free foils was only about about 13. T rudders seemed to do their job - no tendency to dive - was grateful for that - not much boat in front of you. No tendency to fly. My conclusions below, might be different with more wind. 1) In these conditions, the active controls make the boat fly - not the foils themselves. Don't know why - flap is only about 30% of the foil area, seems like there would have been some lift from the foil - but I didn't feel or see it. 2) T rudders kept the boat level downwind (no surprise). 3) "free foiling" would be useful only for beginners to learn the boat and while racing in drifting conditions.
  10. Ok, one more thing before I get on the water this morning - I was concerned about beach launching my S9s before i bought them. In practice, after 14 months, beach launching at Canyon Lake and at TFW Newport, I am still using the undamaged original rudders, foils, and boards. We launched at the same beach with the same technique as everybody else at TFW Newport. 16-18 sailors (maybe more, don't remember the true number), most of them S9 newbies, beach launching and retrieving, and no damage - none. If you prefer some other design, that's great, but practical experience has shown that beach launching the S9 T foils has the same hassle and pitfalls as beach launching anything else. Time for some testing now............
  11. Thank you Steve! Well put. I agree. I think I'll buy one of your desi........oh wait, I already did.
  12. No slide-down rudders - regular pivot-type. Much less expensive I think.
  13. Tuning guide is available if anybody wants it. PM me. Anybody else have feedback on the Turbo kit?
  14. ACS: well, I hope we can agree to disagree. I can handle that. Pretty sure you can, too. I don't have valid standing on A cat issues anyway, since I don't have one. But I do enjoy the discussion on the foils. Who knows what we'll see a decade from now. Setup: we struggled until Michele sent Federico to TFW Newport - he was a terrific resource for us. It was like a different boat when properly set up. We generated an illustrated tuning guide - great help.
