Preventer

Not sure what the problem is here with preventers, but using one is sometimes definitely important. Last years Marion-Bermuda race had us going downwind in 35kts with occasional wavetops breaking. Quartering was not an option. We furled the mizzen, reefed the main and reduced the jib to avoid surfing problems, but in strong following seas and wind it gets intense at the helm. With a preventer, the Mason43 was very forgiving about yaw and roll, but then she is a heavy full-keel boat; the last thing we needed was accidental gybing. Our steering suffered from some bolts backing off, one boat retired with broken steering, and several took long detours to avoid the area altogether. Later on the skippers watch he sailed parallel to get back to the rhumbline but we got boarded a few times and did some uncomfortable heeling. They say any boat gets rolled when the wave is 40% of the boatlength. Recently read Motissiers book on his trip around the Horn. There is some food for thought on downwind work in life or death conditions. He and Coles might differ in details, but they are pretty close in survival tactics. I would not sail without one, whether its to keep the boom from bouncing and swinging in light air and waves, or to prevent injury and damage running under a double reef. A preventer is as simple as taking the vang off the mast and clipping it to the deck. Have also sailed 40+ years, but that doesn't seem very relevant to me in this matter.

Just my way

Sailing downwind. If the wind speed allows me to reach hull speed (or close to it) wing & wing, then that’s what I do if it points me towards my next mark. If the wind is lighter, I’ll make a judgement call. If the seas are rough and the boat is rolling a lot, I will broad reach. I’ve never used a preventer in 20 years. Never broken anything either. Of course, I’ve never sailed in the open ocean either. :)

I have

"Try as I might, I just cannot recall ever needing or wanting a preventer. " At a 175 AWA with winds at 25 knots true and me sailing along the ship channel. I wasn't going to change my angle and have to keep gybing back and forth or having to cross the ship channel constantly. There are times you want to head DDW or very close to it.

Narrow Channels

We have many narrow channels with islands and mountains on both sides (Moody you know this, right?) The winds have a tendency to blow up or down these channels but not consistently due to the mountains and gaps in them. To sail downwind in these channels, you are either jibing every few minutes or sailing dead down wind or pretty close to it. Given the back winds off the hills and other flukey conditions, an accidental jibe is a good possibility unless a preventer is rigged. We run ours forward to a couple of snatch blocks and then aft to the stern cleats. They are easy to rig and easy to release. Given that sailors every year are killed by booms swinging in accidental jibes, it seems foolish not to take this precaution in my opinion. Gary Wyngarden S/V Wanderlust h37.5

Neckhairs are your early gybe warning system...

Unless winds and seas are very light we will set a preventer -- plus a running backstay -- in order to help protect the rig, particularly on overnight passages. Besides the surprise effects of maverik waves, windholes or temporary windvane malfunctions, we not infrequently experience windshifts due to tropical squalls sneaking up on us or catabatic winds funneling down the mountains. Any and all of these surprise events could cost us our rig, especially if the boom were allowed to slam into the running backstay during an uncontrolled gybe. As mentioned by several other posters, it is sometimes unavoidable to sail close to the gybe for extended periods of time, e.g. when following a natural channel between islands or reefs. Especially at night and in poor visibility this can easily turn an enjoyable night watch into a very tiring trick at the helm, especially when trying to maintain the same apparent wind angle on a small digital display. If you find yourself at the helm in poor visibility while having to steer close to the gybe, my advice is to start paying very close attention to the feel of the wind on your neck and cheek. By slowly rotating your head away from the wind till you feel the wind shift over to the opposite cheek you can get an amazingly precise measure of how close to the gybe you are and thus make small corrections, if needed. It will not only help you stay awake better than "sailing by the numbers" but also keeps you in touch with the elements and your vessel. Flying Dutchman

I have always

heard that the boom is the second most deadly piece of equipment on a boat. The liquor locker being No. one!

I must be lucky

My boom clears my head even when I'm standing. No, I am not a midget!

Tight spots

Wow, y'all sail in some tight spots if there is no room to gybe. :D That would mean that there is no room to tack when going the other way ... How do you get home?

Moody Buc, when I get

into such a tight spot I hoist an iron jib and furl all that floppy stuff.;)

Accidental Gybes

The 2 main deadly dangers of an accidental Gybe is getting your head cracked and thrown overboard by the boom or being dismasted by a violent accidental gybe in high winds. On the brighter side, a preventer can prevent this. A preventer can be as simple as running a line forward from the end of the boom and leading it back to the cockpit or using your boom vang if you have the kind that is simply 2 blocks and line. Just unhook the boom vang on the mast base and clip it onto the toe rail or jib/genoa track dircctly under the boom when the boom is out. You can buy an eye of sorts that will go onto your jib/genoa track for clipping the boom vang onto. Why would you want to use a preventer?.. An inexperienced or distracted helmsman could easily accidentally gybe when going DDW or close to it. Why would you want to go DDW or close to it? Because that is the direction you wish to travel. Also, I enjoy Wing and Wing..its a weird sensation when traveling and not feeling any wind, you feel like you are standing still and also a plus on a cold day. Boats accidentally Gybe on light air days all the time. Especially when they are wallowing. Most people either dont pay attention to it or dont realize it, because it is not a problem at the time. Sooooooooo............what happens if you have a preventer and the wind gets on the wrong side of your sails and your boom cant swing over? You make an accidental "u" turn. No big deal. How long does it take to hook up a preventer? under 60 seconds.

And I've heard rumor of sailors going slow wing

on wing so as to enjoy a cold BEER. I have no idea who might have such depraved desires while on a sailboat! And I normally don't pass on rumors except it's the thread subject. ;)

To drink and sail?

To drink and sail is irresponsible, but then again, if we were responsible people, we wouldnt be sailing. After all, racers are nothing but drinkers with a sailing problem. Whew!!!, now i need another beer.

Gybing

As the stern comes into the wind, the leech that is closest to the wind will gybe first. This is usually, but not always, the top of the jib. If you sheet in the jib first, it will give you a warning by luffing first. Next comes the rest of the jib, then the top of the main, etc. Many ketch sailors rarely trim the mizzen regardless of sail point, in which case it will flop over first. A gaff main will gybe bottom first, and if not smartly sheeted in, will result in a "goosewing" gybe (gaff to the new windward, boom to new leeward), both canted steeply upward - enough to make strong men weep.

Ed, Where did you learn that one? Or

more accurately, when? Out of a book right? :) Gaff rigged. I see one on the water about once every couple of years. That's the rig that mothered the invention of the sloop, as I recall.

Gaff rigs

I do read books. I ate up Callahan's "Learning to Sail", "Learning to Cruise", and "Learning to Race" about 65 years ago when I got hooked on this sport on the coast of Maine. There were a lot of gaffers, commercial and private, there then. They used to carry granite and lumber up to Boston and NY. Now it's tourists.

Fred wins!

:) Fred has the right answer. The only reason to sail DDW wing on wing is to enjoy your drink (and to keep the scantily clad wenches in the sun). Gybing is way too much work and might spill the beer, so we should prevent it! Good job Fred *5
