Richard, Crashing webs!

Hey Richard, Apparently, it's not only waves that crash. The link on my previous post was to an excerpt from the book "Surviving the Storm" which I highly recommend. The link was to a page on the setsail.com website. I guess so many people rushed to read the article that it caused their site to crash ;) Hopefully it will be back up soon. Meanwhile, here's something else to ponder. Many decades ago I was reading one of Howard I. Chapelle’s books and he mentioned using oil to reduce the force of waves (works by reducing wind friction I guess). The last news note on the related link has some information on that subject. While some environmentalist may cringe at the suggestion of intentionally discharging oil, I would tell them that it's better to dump a little than having the boat break up and all the oil and fuel and everything (and body) else on board released into the ocean. Happy sails _/), MArk

More oil on water

I found this letter (related link) from Ben Franklin (although it is on an engineering site so I can't vouch for it). Ben relates his own observations of oil calming waves. (Or is it just slicking down the manes on those white horses!) Slick! (sorry) Happy sails _/), MArk P.S.: How do I find this crap? Yahoo, 1MB ADSL link and too much spare time!

Old Mariners Knew About Oil and Water

The old mariners used oil to calm the waves. Pardy I think used oil too. Typically they put oil in a canvas water bag and hung it over the side. A small amount of oil would leak out and calm the white water. Who thinks of preparing a blue water voyage now with a water bag?

R.W.L.: why go look for a 12-hour storm??

If you sail between the Tropics of Cancer and Capricorn, i.e. between 23.5 degrees North and South while carefully avoiding the cyclone ("hurricane", "typhoon") season, practically your only chance of encountering gale force winds or worse (i.e. Force 8 and higher) is in a thunderstorm or by being "williwawed" downwind of high mountains. In both situations this would rarely last more than 1 hour. (If anyone does not believe this, just read the pilot chart descriptions for the Pacific or Atlantic. As an example I have posted the NIMA pilot chart wind description for the South Pacific in August under the photo link). So, why do we see lots of cruisers get time and again in heavy gales or worse, e.g. the hapless Queen's Birthday fleet? Simply because they sail into higher latitudes; more often than not because their traditionally built heavy vessel cannot sail to windward in the Tradewind belts. Of course, once you have taken your full-keeled crab crusher to a high enough latitude to finally find the gale/storm you were afraid off all those years you can go below and close the companion hatch after employing the passive tactics that these vessels are especially built for.....

Henk, That might be true for the Pacific

But the North Atlantic might be a little different (yes below 23.5 N). I know sustained high winds and seas (Force 8 and higher) outside cyclone ("hurricane", "typhoon") season is very common up here. And you can try as hard as you'd like to avoid it. But it is *very* common to have bad weather and seas for more than a few hours sailing from New England to the British Isles. Pick any weather window or time of year you'd like and you cannot lower the odds as low as one would like. If you are not prepared for some extended heavy weather sailing this route than you are just playing a game of odds as good as anyone in Las Vegas.

Tom, are we on the same planet?

For the life of me, I cannot figure out how you can sail from New England to the British Isles below 23.5 N..... Just so we are on the same sheet of music (and perhaps even on the same planet) please consult the pilot charts, check the hurricane season boundaries there and then tell me which North Atlantic areas below 23.5 N do not have Force 9 (and above) winds listed as very rare (when excluding thunderstorms and katabatic winds, as mentioned before). Naturally, even very rare events DO occur, of course. So, I am writing this to you in the assumption that Stamford has NOT just been hit by a tsunami, earthquake or tornado and you are able to retrieve and read your e-mail. Fair winds, Flying Dutchman

Sorry Henk I read you wrong....my mistake.

When you said 23.5 degree's I was thinking (and stupidily assuming everything) "above" 23.5 degrees , not what you meant as that narrow equatorial band very far away from me...........Because, Hell.... EVERYTHING in THE CONTINENTAL UNITED STATES is outside your 23.5 degrees . So if you want to keep the discussion outside of the mainland US then OK. So I say "sure" if I stay inside that band AND stay outside of the hurricane season. But lets bring this discussion back to ALL OF THE EAST COAST. I know scores of North Atlantic Sailors that say you can't reliably expect nice weather like you are saying...Because it is VERY common to find long periods of time with wind speeds between 34 to 40 kts .......... I notice you are now saying Force 9...what is it Force 9 or Force 8 !?!....And ok tell me the EXACT odds of having a 14-20 day window where the winds will be mild like you are suggesting.....yea sure they happen!....But should we be encouraging sailors to take steps out into the the North Atlantic expecting only benign conditions !?! THAT IS RIDICULOUS !! When I am in Central America (or inside your nice latitude of 23N and 23S) and then I will follow your advice.... But there is alot more ocean out there. The odds are AGAINST you to find a 2 week window WITHOUT extended 34-40kts winds sailing to England.....it can happen BUT... And sending out people with a false sense of security is irresponsible.

Tom

And just to reinforce the point that extended

winds and seas can occur on the East coast often, just look at the original post talking about the Carib1500. Even though the organizers of this trip do *everything* possible to find the best weather/wind possible they STILL are forced to run into rough weather. As the original poster said " in the Caribbean 1500. Winds were in the 30-40 knot range for several days with gusts over 45 knots. ".....its not just a fluke.....

Was the weather that bad?

When you look at the carib1500.com race web site at the official weather report, the weather didn't appear to be that bad. Most of the high winds encountered during the race were found near squall lines moving through the area. It seems that the only day with really bad weather was on November 6 when winds near a passing cold front had winds at 50 kts. Several of the boats were reporting being heave-to because of the high seas and wind conditions, but it cleared up when the front passed quickly through the area. On the rest of the race days, the winds were moderate to light for a race. Fair Winds. Clyde

Seaworthy doesn't mean slow

Henk seems to think that a boat designed for offshore sailing, with good stability, and comfort characteristics will also be slow. The link below takes you to a description of the Cal 40, a beautiful ocean cruiser-racer that was designed in the '60's. It has a capsize screen of 1.77. Her estimated AVS is 150 degrees. This is a boat that would take care of you in a storm. But it is renowned as fast. And "Glider", a reconditioned Cal 40 won her PHRF class, and finished 10th overall in the 2001 Mackinac race against modern Hunters, Catalinas, Beneteaus, and other modern, beamy designs! There _are_ designs that are fast, light, and go well to weather while still having a high AVS, and other storm safety characteristics. But wide, flat boats with the wide beam carried aft are easier to roll over in breaking waves in the 20 to 30 foot range. And they are likely to stay over once inverted, as has been proven again and again. A word about weather risk. 3 of the storms analyzed in Adlards Heavy Weather Sailing occurred closer to the equator than 23 degrees, and outside of cyclone/typhoon/hurricane season. A key point of the book is that unexpected weather does come, even where the pilot charts say it is rare! The Fastnet race was run in August, which has a deserved reputation as a relatively calm month in those waters. Waves were over twice the typical maximum height for August, and 40 percent higher than any season in 20 years. The unique risk of blue water sailing is that when the unexpected happens, we and our boats have to ride it out. And the excitement of the sea is that over the years, the unexpected _will_ happen.

Fast is Kinda Relative

The Cal 40 is a really nice sailing boat and I have a lot of respect, and "fond memories" for the way it handles. In the late '60s I crewed on a Cal 40 out of Saint Francis on San Francisco Bay where afternoon winds are standardly in the low 20s. "Driving" her to weather up Raccoon Strait was a pleasure and she'd take those rolling whitecaps gracefully and without slamming. Trips out the gate and down to Monterey were fun and I always felt secure no matter what the weather was and we had our share. Our boat finished 1st in the fleet of about 40 Cal 40's. Fast? The '40 sailed really well but some of today’s designs will give her a run for the money. It was a Pacific Cup race, San Francisco to Hawaii, over 2000 nm, where a Cal 40 with the acknowledged top tactician in the entire fleet raced against a new Hunter 35.5 with a no-name crew and the Hunter won. And the guy on the '40 bought the boat and tweaked it out just for that one race! I remember one comment the '40 skipper said, at one point they had the spinnaker up but it was so rough they couldn't take it down. This was around '90 or '91 and there were some really rough conditions they had to sail through - not your everyday sleigh ride. If I race my H-35 ('88), and I haven't much, it's put in the same group with the Cal 40's for PHRF purposes, an indicator we're about even for speed and this is supported by the races I've been in. If I went to sea which would I prefer for safety? the '40 for sure, and they have a good sea motion. Stack the Cal 40 up against a H-43 and it's no contest, the 43 will literally run away from it. Any builder that shortens insulation around the icebox or won't seal a through-deck penetration to prevent water intrusion into the balsa core deck you have to wonder about where else they short-changed the design. Rudder shaft? I wonder about these things. Some people worry about shaft seals, I worry about things like rudders and lightning; to each his own. Especially with answers like "yea, so it [leaks][doesn't keep stuff cold][enter your problem], it's a PRODUCTION boat". Implying one needs to expect a few "flaws", I guess. I wonder what else is flawed? As you can tell I have a fairly low level of "trust" in today’s "production" boats. With regard to unexpected weather, it does happen. For example, it's been told the best sailing in the Northwest is in August. Blue skies and kinder winds. Well, we were sailing around Vancouver Island in '91 and for several days the weather people were saying there is a strong system approaching but it never came. The skies were blue and day after day of good weather and finally we decided to leave anyway; the forecasters don't have a really good reputation for this area. A couple days later the storm hit and it was a whopper. After a brief lull of a few hours the real storm hit. Solandar Island weather station blew away at 103 knots! This wasn't a summer squall, this was a couple day storm! Actually, a hurricane and this was around August 6th to the 8th. Fortunately we were able to tuck into a good harbor about 30 miles away but others were less fortunate. A trimaran was lost for a couple weeks and found upside down. The crew survived on canned cat food! This is one of the scary parts about cruising, that conditions can become significantly worse than forecasted.

Safety Is my point

I think there has been some good discussion here. My point was that there needs to be an alternate plan. The question I ask to all the captains here: How will you prevent harm to your crew and boat? What is your plan? For instance two people on the boat and one gets hurt just as a storm is approaching. What then? You are demasted and turned sideways to the waves. What then? You lose your rudder. What then? I like a plan. I know my plan. That way I can work it, should something happen. I have been in enough situations that things were going well then one thing happened and we had big trouble. I have spoken of the below experience before. I was racing in lake Erie at night with a guy I had met the day before who was short handed. I decided to go with him. He had abuddy that came for the race also. His buddy had sailed 4 times. There was some pretty good waves (4-6) but things were going well...(we were second to last)We had to tack toward shore into the waves. The going got rough pretty quick. The owners buddy turned green on the spot. Heaving over the side and worthless as crew. The pin came out of the main tackle and the main sheet had to be wrapped on the high side winch. The owner went below to find another pin which he could not find. When he came up, he was green. There was no tiller tamer and I could not get the main down by myself in those conditions.I had to keep my eye on both of the other guys. The buddy was in the cockpit and the owner went to the bow with no safety harness. WE DID NOT HAVE LIFE JACKETS ON! I could not have gotten one on myself no less on either of the other guys. NOTE TO SELF: PLAN AHEAD! I made many mistakes that day. I thought that if things got bad we would have time to put on our PFD's. Not knowing the captain and his sailing ability, not having a PFD on, the owner would not turn on his vhf, I had no idea what the interior of the boat was like nor where the tools were kept. One man on one of the other boats was knocked overboard and lost. He had no PFD on either. He was found 4 days later. I bet that captain and crew (totaling about 8 men)still have nightmares. r.w.landau

David, more details about the 3 storms, please

I have been out of state for a few days and already wanted to ask you to provide some more details about the time, place, severity and duration of the "tropical" storms described in the new edition of Heavy Weather Sailing. I would like to buy it myself one day but have already spent my Xmas budget for books, and then some :0( Fair winds, Henk Meuzelaar "Rivendel II" PS Are you a scuba diver? If so, have you already been diving on the "David Foster"? If she lies not too deep it should be a great thrill to dive on a vessel bearing your name! HM

Tom, agree with your rant against N Atlantic Xing

While one can certainly cross the N Atlantic with Benehuntelina-like vessels, as countless examples show, one can alas never exclude severe weather in the Variables (as the name indicates). One more example of that is the bad West coast weather situation cited by John Nantz. In principle, however, even the North Atlantic can be crossed within the Tradewind belt (e.g. via de Cape Verde islands and the Caribbeans, though. Almost nobody will consider that route because (a) to and from higher latitude ports it is quite a detour; (b) the hurricane season tends to be long and fierce; and (c) the US to Africa leg would have to be sailed AGAINST the Trades (which is unconceivable to nearly all traditional-thinking sailors). Now get out the globe and look how one can get from a US coastal location on the East or West coast to the tropical bluewater cruising grounds below 23.5 degrees North. Right! Just follow the coast until you get far enough South. Between Florida and Cuba you have to cross a bit of open water, etc. However, that can always be done in an overnighter and within the weather forecast windows (OUTSIDE the hurricane season, of course). Now, it so happens that I have personally found coastal sailing along the US coasts to be more risky and demanding than a longer passage within the tropics (i.e. between 23.5 N and 23.5 S). Some people on this board appear to feel safe along the coast because there is usually a harbor not too far away if the s@@t hits the fan. However, the frequent strong NW and NE winds (on the West and East coasts, respectively) can rapidly turn either one of these coasts into a dangerous lee shore. Yes, you can try to head for the harbor, but you may get only one shot at it. If your navigation is off by a bit there may be no way back! Over the years I have learned that there is no substitute for maximum searoom near lee shores. Moreoever, on the West coast many harbors have sand bars that become nearly impassable in strong NW winds. Finally, there are the feared Points and Capes. It may do you little good if the nearest harbor happens to lie just around the next Point or Cape..... At any rate, let me repeat, if you already feel comfortable sailing coastal routes in the higher latitudes, doing an offshore passage in the tropical latitudes is likely to be a walk in the park by comparison. Have fun! Flying Dutchman

Rudder Question for Henk

How about some insight from someone who is out there and doing it? After reading your list of improvements and added gear to make your vessel stand up to the blue water environment it's obvious you've given "everything" a great deal of thought. A 43 is a pretty good-sized boat and caries a large rig capable of generating some pretty good-sized forces. If you plan to continue your South Pacific sojourn and make the crossing to New Zealand, in light of the recent H-45 rudder problem in the ARC, I was wondering if you have any thoughts or concerns about your rudder system? You know, like little voices in the night before departure? Any plans for a backup system or improvements to same? Additions to a contingency plan? If the original rudder failed due to rough sea conditions a backup system on a boat the size of a 43 would need to be pretty darn stout. So much so that if the original rudder ever did fail due to rough conditions I don't see how a short-handed crew could put a backup one into place given the weight and conditions. The 43 isn't billed as a "coastal cruiser", that I'm aware of, so hopefully the builder has a good factor of safety built in. By the way, several years ago I talked to someone with a 43 from Port Ludlow WA that sailed from near Fiji to New Zealand and they narrowly escaped a major system thanks to his boat speed. It's a long distance and systems can brew up fast. The other blue-water boats making the same trip got caught because they were too slow and consequently got clobbered.

Rudder system redundancy on Rivendel II

Yes, John, I would indeed have some concerns about the rudder. But before elaborating, let me repeat again that I feel that the Legend 43, and vessels of similar ilk, can be made into nearly-perfect Tradewind cruisers but should think twice before undertaking offshore passages in the Variables and higher latitudes. Every year, about one in three of our cruising friends making the passage between New Zealand and New Caledonia, Vanuatu or Fiji runs into a strong gale or storm in the 50-60+ knot category. At the moment, however, we have no immediate plans to sail to New Zealand since Project MARC, our medical and educational assistance project for the remote island communities in Vanuatu (see website link below), not only keeps us here but brought us back from Queensland, Australia in June/July 2000. As the number and size of international cruising vessels helping Project MARC increases steadily each year, however, we may well find that "Rivendel II" is no longer an essential link in the project and either decide to sell her here in Vanuatu (i.e. at the end of the 2003 season) or sail her to New Zealand (in spite of my earlier avowed reservations) to use her as a coastal cruiser there. With regard to the rudder; here is the deal: (1) due to the use of our AutoHelm windvane with large (nearly 6 ft high!), transom-mounted accessory rudder, Rivendel's main rudder tends to see light use only. Most of the time it stays locked near-center while the accessory rudder steers. Nonetheless, we are keeping a close eye on condition of the aluminum pedestal base (corrosion!), cables and quadrant. Also, the rudder itself is carefully inspected each year and to make sure it has no water inside and there are no signs of ablation between the 1 3/4" stainless steel shaft and the FRG rudder body. Nonetheless, I think that the amount of play between the shaft and the shaft tube has slowly increased a little bit over the years (thereby increasing the potential amount of shosk-loading) and I have often thought about having a modern rudder shaft bearing assembly installed. Needless to say, of course, that would be a major operation. So, what is the plan if we would loose the rudder. Well, first of all, I want to reduce the chance that the same mishap (e.g. u/w collision with tree trunk) would take out both the main rudder and the transom-mounted accessory rudder. Therefore, I have made a stainless steel, spring-loaded clamp that is designed to break loose in case of a major frontal or sideways blow, thereby letting the rudder rotate upwards till it passes over the obstacle. It's basic design is similar to a transom mounting plate for a large outboard (and can in fact be used to mount an outboard after removing the accessory rudder). Unfortunately, since the springs need to be very strong and tightened down to avoid the clamp coming loose in heavy seas, there is no real way to test the system (e.g. with a sledge hammer) without potentially damaging the rudder or it's brackets. I just hope I will never find out whether it really works or not..... Hope this answers most of your questions. Flying Dutchman "Legend 43"

Twin Rudders?

Hitting a floating solid object with a rudder would be a real concern. In the Northwest and Southeast Alaska it's a constant battle to dodge deadheads and logs. One summer at Port Hardy there was on average about one boat per day pulled out from hitting floating debris, mostly powerboats. The H-43 goes pretty fast and I've heard that 9 knots is not uncommon. Hitting a log or large fish/whale at this speed is likely to make a good noise or worse. A lot of the round-the-world racers now sport dual rudders. These work better when the boat is heeled and also provide a redundancy. However, two rudders are more expensive (2x - except there would be some reduction in cost due to quantity), and the steering mechanism would be more complicated. Of course these boats are going even faster than we are. Was it last year a H-34 from Alaska was having rudder problems? In Latitude 38 there was a letter where the guy wound up having two rudders sent to him in the South Pacific. If a manufacturer is going to build boats for over the horizon cruising then they should provide a reliable and robust steering system that will hold up for regular steering and even hitting some floating things. We aren't expecting a rudder to stand up to hitting a reef. Mounting a rudder on a spring-up system sounds interesting. The stern on our 35 is really light-weight fiberglass and I wouldn't trust mounting anything to it unless it is really beefed up which would be really hard to do upside down in the inside. Then after the rudder there's the question about protection from getting holed. A watertight forward bulkhead would also be a nice addition. Glass in the bow water tank area. The Bavaria uses carbon fiber material in the bow which would really help and you'd think wouldn't cost all that much. Well, sounds like you really have it pretty well thought out. I enjoy reading your postings - you keep us thinking. -= John =-

Don't our modern fin keel/spade rudder boats

come with a "breakaway" rudder? I have heard, in more than one place, that the rudder of most of our boats are designed to have the bottom half of our rudders "breakaway" in case it hits something hard. This way it takes the brunt of the impact and doesn't allow the the forces to go up the rudder shaft into the hull. (It would be alot worse if the rudder didn't break and forced the hole in the boat where the rudder shaft goes in bigger!). You would lose about half the surface area for the rudder and I'm sure steering would be sluggish especially in heavy sea's. But I'd rather have 1/2 a rudder than none at all. This is one case where a full or modified full keel would excel. The chance of losing a skeg hung rudder from impact is less and keeping directional stability on a full keel is better. I agree with John about the watertight forward bulkhead and a high tech material in the "impact" zones like the bow (But I would think Kevlar is better than carbon fiber material). If I was trully going world cruising, I think this would be one of my "really want to have" items.

Kevlar Reinforcement and Rudders

See these links. Hunter does reinforce the bow with Kevlar (and elsewhere). Also, see the note on rudder construction, on the other link. RD http://www.huntermarine.com/about/innovate/kevlar.htm http://www.huntermarine.com/about/innovate/rudder.htm

Rick good info, does anyone know of anyone hitting

a hard sharp object in these areas at speed? And what the result was. Just curious, I'm sure with kevlar reinforced its much better than nothing. I think, more likely you'll hit with the keel (lower in the water and more area to hit) and then the biggest concern is the keel to hull connection and Keel Bolts, but hopefully, if anything it'll just be a slow (manageable) leak and a huge dent in the keel. I read about the composite rudder posts, but it doesn't say anything about a breakaway rudder on the lower part. I am less concerned about a stout stainless steel post and what happens when the composite shaft gets hit hard, does it just shear away (Like a carbon fiber might -- higher strength for weight/but more "brittle" and more likely to either be whole and straight or snapped off.... ) So does it bend like stainless steel. I think I'd rather have a rudder shaft be really bent and hard to turn then one that completely shears off. Does anyone know specifically what happened to the Hunter Legend 450 that was participating in the Atlantic Rally for Cruisers this year? They had loss their rudder in big seas earlier this month and had to abandon their boat. I know we can all speculate on what "might" have happened but does anyone have any web links into the details?
