Posts: 66 Durban, KwaZulu-Natal, South A... | This weekends forecast is predicting a solid 25Knots wind. This is on my limit but I'm racing and would appreciate any advice from those who've tamed such winds  I'm looking to go for max rake, lots of downhaul and outhaul with the travellors on both the jib and main out enough to keep the boat flat. If I've missed something, or you have any additional advice which might help, please chuck it in. I'm expecting large swell, but smooth sea's with respect to small chop. Just a little nervous...  Thanks Clint

Posts: 72 Montreal , QC | Good luck. Agree with your comments and H77's. Foot straps/holders are a MUST. Your most aft is about 6" from the stern, the other as aft as possible on the sidebar. They are essential on a reach and keep you in place when in waves or stops 'n starts. When tacking in big winds I'm usually on the trap, close hauled, hulls level. As the cat comes into the wind, I head aft to help "pull" it through the wind. Timing is critical - as you feel in coming through and you get that "I'm gonna make it" feeling, pull yourself up quick, let out the main a little as you transfer to the new windward side. Once there, (I'm usually solo), I uncleat the jib and sheet in quickly to the new heading, trap out and sheet in the main. I'm sure you'll get lots of other helpful ideas. Hope you do well. Ron

Posts: 124 offshore | OK, so someone tell me what is the best way to sail downwind in a 16 when it is blowing the dogs off the chains. I am still trying to unlock this one!
In Delaware at the NAs in 2003 we had one day of BIG wind on Thursday. (Race committee reported sustained 30s and a puff to 44!!)
It seemed the preferred approach was to let the jib flog (so as to not push the bows down), travel the main out (so as to not gybe!), sheet on hard and be ready to do the big ease in a puff, and drive as low as you dare go without gybing.
All of that makes sense to me. But looking at the South Africa Worlds photos, i am seeing these guys sheeted off big time. It seems to me if you sheet off you present more of the sail perpendicular to the wind. Yes, it opens the leech, but you still have that big rag 90 deg. to the wind.
Thoughts?

The one and only time I reefed the main was for the afternoon races at regatta with reported gusts up to 50mph, and it worked very well. You know it's some serious wind if some people actually race with reefed mains or furled jibs. I was trapped and steering only, power was controlled by my wife with the jib sheet, sawing in and out with the gusts. Never capsized...after we reefed the main

Posts: 465 FL | Here is some stuff I wrote here a while back. If you use the 'search feature" you will find more. Bon Chance. Chris
Have you ever seen a plane fly backwards? or stalled? Sailing stalled out (falling in an airplane) with managed projected area (twist or travel) is the key to reducing the excess of wind power you are experiencing. Every notice how slow it is when the crew oversheets the jib, he is depowering/STALLING the sails. Have you ever seen a plane fly backwards? Sailing stalled out with managed projected area is the key to reducing the excess of wind power you are experiencing.
I addition to getting your weight back, pull your main traveller (& jib) near the center of the boat with minimal twist(sheet in tight), steering ALMOST Dead Down Wind. The closer the mainsail is to the centerline the smaller the projected sail area to the wind reducing wind force and pitchpoling. This sail configuration puts the sail in a STALL, like an airplane falling through the air NEGATING lift.
************************************** So downwind try sheeting in the jib in the puffs to stall out. To depower more travel in the main to reduce projected sail. To depower more and stall out reduce twist(sheet in) and enter the 'Stalled Out Zone'. (CAUTION sailing stalled in winds under 20nt is SLOW) **************************************
For steering DDW try using the following (3)three indicators, that kind of 'check and balance' each other. First, the bow wind indicator. Second, pay attention to the feel on helm. You can maintain a very slight weather to neutral helm with the sails stalled out. If the helm goes a lee you WILL eventually jibe, so push the helm away from you to get back to neutral helm. If the weather helm helm increases pull the stick to get back/close to neutral helm. Finally, with the jib strapped in (stalled) watch which side the jib FAVORS, as it oscillates back and forth (how it behaves) out of the corner of your eye, and react accordingly. This is useful when it is raining so hard you can not see the bridal fly.
Looking behind you, often helps, as you can sheet in before the puff (dark water) hits you. Its FUN watching the other boats go over next to you, as they let OUT their sails.
when the sail stalls and the effective shape looks like a big fat wedge whose lee side isn't bending the wind near as much as you'd like, so the lift (component of the force at right angles to the apparent wind) is much less and the drag (component of the force parallel to the apparent wind) is excessive. The combination of the two is smaller and points aft, robbing the boat of the drive.

Posts: 124 offshore | Yes, Matt, it is interesting to see the 16 reefed!
As for stalling out the boat by sheeting in, I think that may take bigger kahunas than I got! At the 1992 (?) Hobie 17 NAs in the Gorge, I pitchpoled every which way, including "stalled". I tried traveling in, sheeting out; traveling in, sheeting in; traveling out, sheeting out; and traveling out, sheeting in. None of those combinations worked. Of course, I have 13 years more experience now than the 7-8 that I had then. But still....
In Delaware it was 35-45k. The technique that Paul Hess told me to use was to travel out, sheet on hard, sail deep, deep, deep, and be ready to release the main sheet as soon as a puff hits.
After the puff passes is when the fun begins. Now you are trying to cheat that sheet in and get it in far enough so you have something to let out when the next puff hits!!
The first time around A-mark (before our 1st pitchpole), we were a couple boat lengths behind Wally and it looked like he had his main traveled out.
One thing we should've done in Delaware was let our jib flog. We were (trying to) sail with it.
We eventually did finish the race -- after flipping 6 times! But hey, we got 29th! That's because the other 42 boats had the good sense to get out of that crap!!! We even beat one poor sucker.
If anyone has any other techniques -- other than the 'stalled' technique -- I'd be interested in hearing them. It isn't that I don't believe the stalled technique will work, it's just that I don't think I have kahunas big enough to go down that path!!

Posts: 1,187 38.912, -95.37 | Reefed the main for the second time in my life last Saturday. Wind 20 gusting to 30, three to four foot capping like crazy, only windsurfers and kiteboarders on the lake and no crew. At 162 pounds, even reefed, was grossly overpowered so I traveled the jib all the way out. This was sort of like flogging in that when the main was trimmed, the jib was luffing severely. It did allow me to "survive" the upwind tacks by starting the backwinding earlier and help whip the nose on around through the big chop. I tried to leave myself plenty of room from shore and not tack in the gusts to avoid "climbing the tramp" while backwinding. Just did my best to make a normal roll tack.
It was rather harrowing on the reaches (I really need footstraps...ever notice you're curling your toes to grip the rail?) almost blew over twice from the jib only. After about 40 minutes, thanked my lucky stars for quite a ride and halled her out.
I don't have a good answer for running downwind.

Posts: 393 Syracuse,N.Y | Peter: My opinion; Sailing and Racing in the Rehobeth style conditions in both 98 & 03 are two differant things. You are a racer and not only want to go down wind, but do it with speed. I have never seen a top sailor try to sheet the traveler in downwind. Having the main in some, so you have something to dump, and not being dead downwind, so you have somewhere to go, are both key. Both are very difficult. When going downwind stalling the sail slows the boat down and increases the wind over the boat and makes it easier to pitchpole and harder to jibe. Knowing and doing are very differant. I drove both bows into the mud in 98 in the race you mentioned. I remember the hurricane at A mark(measured real 38knots) and then trying to turn down wind. I stayed out and started the next race when 11 of the 22 boats that stayed out went over within a minute of the start. Soon after they abandoned. As mentioned above, I watched the Brazil and PUR boats flying. We just don't get the practice in those conditions. The link shows Wally at this years Madcatter showing his downwind form in 30ish. He's pretty good. Practice, Practice, Practice. We all need to hold one of your programs for racing in PUR this winter. http://portcredit.net/gallery/displayimage.php?album=1&pos=56

Posts: 124 offshore | That is a pretty funny picture -- reefed main, no jib, and 4k!! I know, I know -- it blew itself out!!
Thanks, Pat, for confirming the technique. I picked up one more idea from your post -- don't head DDW -- cheat up when you can so you have somewhere to go!
I think in DE my white knucles were pulling on that tiller to get low, low, low! That meant my only 'escape hatch' was dumping the sheet. Adding steering to that equation gives me one more option.
I remember seeing and studying that photo of Wally after the Madcatter. (See, I do spy on you guys!!) I thought "Gee, he sure does have that boom out pretty far." But then, the pic may have been snapped right after he dumped a bunch of sheet. I know in DE I was sheeting that main on every chance I got so I would have something to release (and to reduce net sail area perpendicular to the wind).
You're right -- practice, practice, practice. Puget Sound doesn't get a whole lot of that. But we do have Gorge 3 hours away! I like the PUR idea. Laura Sullivan & I were talking about taking a trip down there and trying to hook up with Enrique. He probably doesn't have the time with the Tornado Olympic campaign, but we thoguht it would be worth a try (esp. since we have a few connections!).
