The most wonderful mystery

0

A READER in Newport Beach, California, says she would like to know what the Bible means when it says:

 "There be three things which are too wonderful for me, yea, four which I know not:
"The way of an eagle in the air; the way of a serpent upon a rock; the way of a ship in the midst of the sea; and the way of a man with a maid."

Specifically, “Nautigal” wants to know about the way of a ship in the midst of the sea.

Well, ma’am, science has made great progress since those words were written. We can explain an eagle’s flight with aerodynamics. Herpetologists now know how a snake slithers across a rock. Dr. Phil understands all too well the wicked way of a man with a maid (and spares us no details). And that leaves the ship in the midst of the sea, the most wonderful of all the mysteries.

Little ships, and especially little sailing ships, conduct themselves in many different ways in the waves of the sea. You may have experienced them all without giving any particular motion a name or a definition. But one man made a list for us to wonder at.

He is the well-known American naval architect and author, Francis S. Kinney. He held that there were eight motions of a sailboat at sea:

Broaching: Accidentally swinging broadside on to the wind and sea when running free.

Heaving: Rising and falling as a whole with the seas.

Pitching: Plunging and scending, so that the bow and stern rise and fall alternately.

Pitchpoling: Accidentally tumbling stern-over-bow in a half-forward somersault.

Rolling: Inclining rhythmically from side to side.

Surging: Being accelerated and decelerated by overtaking swells.

Swaying: Moving bodily sideways.

Yawing: Lurching and changing direction to either side of a proper course.

I note that the discreet Mr. Kinney refrained from mentioning wallowing and foundering, which has happened in boats I’ve sailed. The foundering was in a small sailing dinghy, luckily, and there was a sandbank nearby. Perhaps Mr. Kinney’s designs never did those things. But he might well have included heeling, which is simply deliberately arrested rolling.

So next time you’re out there, “Nautigal,” take note of what your boat is doing, and at all costs avoid pitchpoling. That’s the most dangerous motion of all.

Finding the right balance

0


A READER in Anchorage, Alaska, who calls himself or herself “Iceberg” asks if I could repeat a column I recently wrote about balance in sailboats. Well, I don’t remember writing about that subject recently, but I did write about it many years ago. So here’s hoping that this is what you’re after, Iceberg:

 

THERE ARE MANY DESIGN FAULTS that sailboat owners will admit to, but unseaworthiness is not one of them. A skipper might well shrug off a lack of accommodation. He or she might well agree the boat is slow, or hard on the helm. But nobody wants to own an unseaworthy boat.

Seaworthiness is the happy result of a lot of factors but there is one that is often overlooked. It’s called balance.

According to Tony Marchaj, a sailor, pilot, naval architect, and research scientist, “Almost by definition, seaworthiness cannot be achieved if the boat is badly balanced.”

So what do we mean by balance? That question was answered by a famous British designer, J. Laurent Giles. He said good balance is “freedom from objectionable tendencies to gripe or fall off the wind, regardless of angle of heel, speed or direction of wind.”

He added that a well balanced boat had an easy motion in a seaway, that is, she passed easily over the waves, neither tending to plunge the bow deeply into the next wave ahead, nor throwing her nose high in the air as a wave passed the fore body. She would also unfailingly lift her stern to a following sea.

“One requires of the balanced yacht that she should retain the utmost docility and sureness of movement in manoeuvering at sea, in good or bad weather,” he added. “She must maintain a steady course when left to herself, but must be instantly responsive to her helm so that the heavier seas may be dodged if circumstances permit. She must be capable of being left to her own devices, sailing, hove-to, or under bare poles.”

That sounds like a very tall order to me. What sort of hull has this wondrous quality of balance? Here’s Marchaj again:

“In a narrower sense, this means that the inherently balanced hull does not substantially alter its longitudinal trim, and does not alter its course during the process of heeling and rolling.” In other words, to be well balanced, a hull, when heeled, should immerse about the same volume of topsides forward and aft.

Marchaj points out that many of the good old boats still sailing now were either designed for, or affected by, the old International Offshore Rule, which produced shallow, beamy hulls with pinched bows. “Usually, when they heel, the stern is lifted and the bow falls. Consequently, these boats are difficult to control by rudder and are unseaworthy.”

If the bow digs in as the boat heels, a boat will try to round up into the wind, of course, not only because of the wedge effect of the forward sections but also because the center of lateral resistance has moved forward while, at the same time, the center of effort of the sails has moved outward and gains more leverage. This is when the person at the helm suddenly finds the tiller up under his chin. Not that it does much good if the boat heels too far and the rudder comes out of the water.

Luckily, most of us don’t often sail in sea conditions that challenge the full seaworthiness of our boats. But if you should be of a mind to cross an ocean or sail around Cape Horn, balance might be a good thing to keep in mind as you search for the right boat.

A better way to start the engine

0

I’VE SAID IT several times before, but nobody seems to take any notice, so I’ll say it again:  It’s high time all inboard engines for pleasure boats were fitted with starters that don’t rely on electricity. There are other ways. There are hydraulic starters, compressed-air starters, and even a wind-up spring starter — but have you ever seen one fitted in a yacht?

It’s quite wrong that we’re so dependent on electrical batteries for starting our motors. I guess it’s a hang-over from the automobile industry, where there is usually no safety concern if a battery goes flat.

But things are different on the water. A fully discharged battery can be a much more serious matter, particularly on a single-engined boat. A flat battery can involve discomfort, embarrassment, expense, and even danger.

Hydraulic starters are used on some commercial craft. Hand-pumping an accumulator tank for five to ten minutes will spin a big diesel for two minutes or so. Some fishing boats used similar compressed-air starters.  There used to be a British company that made a spring starter, maybe still does. It fit on your engine like a regular starter, only it had a crank like a winch handle sticking out. Twelve turns of the handle would give you enough spring power to start a six-cylinder diesel.

Haven’t there been times when you’d have given a back tooth for a system like that?

I once owned a single-lung, 12 h.p. BMW diesel which had a valve lifter that automatically snapped shut after you had spun the engine with a crank handle about four times. Without compression it was quite easy, using both hands, to crank the engine up to a fair speed in four revolutions. It is a great emergency back-up system for engines up to about 15 horsepower. Won’t someone please whisper this fact in the shell-like ear of a marine engine manufacturer?

Learning to trust your crew

0

A sailor I know told me the other day that he is hesitating about buying a bigger sailboat because he’s afraid his usual crew — his two teenage daughters — won’t be able, physically, to handle the bigger craft.

Now I am too streetwise to get into an argument about the capabilities of women, but I was reminded that several years ago I wrote a column on this very subject. I dug it out and gave it to the worried sailor; but it struck me that the advice I handed out then is still valid today. Here it is:  

A FRIEND OF A FRIEND is dreaming of crossing the Pacific under sail. He normally holds down a highly technical and well-paid job, but he’s out of work right now and not likely to be hired again until the economy improves.

However, he is a frugal man and has husbanded his resources. So now he’s thinking that this might not a bad time to turn his dream into reality.

His loyal wife, who crews for him on their 32-foot cruising sloop, is happy to go along with him, but he is worried about his two daughters, aged 16 and 14.

“If they were boys I wouldn’t have a moment’s hesitation,” he says, “but I’m not sure girls will be able to handle the hardships.”

Well, I don’t know these daughters of his, of course, but I can’t help thinking it’s a bit old-fashioned to regard girls as lacking in the ability to handle crew duties aboard yachts. What they might lack in brute strength they surely make up for in ingenuity. You only have to be able to read to know that girls of 15 and 16 are sailing bigger yachts than his around the world on their own these days.

Besides, boys don’t always make idea crews anyway. The last time I crossed an ocean with a son, who was then 17 years old, I lost a lot of sleep worrying about him.

As we were the only two watchkeepers, he had specific orders to call me if he spotted another vessel at night. He had specific orders to call me if he thought a sail change was necessary. He had specific orders to wear a harness and tether when he was alone in the cockpit at night.

But he was 17. He was becoming a man. He couldn’t help himself. Nature was pumping testosterone through his tissues. He didn’t obey any of those orders. Although he was color blind, he guided us through a fleet of fishing boats one dark night way out in the South Atlantic while my wife and I slept below. I nearly had a fit when I found out.

And when we were running fast in the southeast trades I was woken up one night by the thud of footsteps running forward along the cabintop. My untethered son was jibing the foresail singlehanded, shifting the pole from one side to the other. I lay awake, staring into the darkness, listening to the noises, waiting for the thuds that would indicate he was returning to the safety of the cockpit. But they never came. Had he gone overboard? I reasoned — I hoped — that he had returned along the side deck. I wanted to get up and peek out of the companionway hatch, but I didn’t want him to know that I had caught him in an act of disobedience because that would have forced me to impose disciplinary punishment or else lose my power of authority over him, such as it was. So I lay there fretting for another half hour until it was time to go on watch and I could decently make an appearance. And there he was, sitting in the cockpit, neatly buckled up and looking the picture of innocence in the moonlight. I could have bitten him. But I didn’t ask him why the jib pole was suddenly on the other side.

I don’t think a girl would have disobeyed her father/skipper like that. Girls don’t have the same impulse to prove they’re macho.

Or do they? Maybe now I’m the one who’s acting old-fashioned. Well, if I am, I can’t help it. Old-fashioned is what I am. Like it or lump it. But my advice to the friend of a friend is simple: Go for it. Invest some trust in those daughters of yours. I’m sure it will be amply repaid.

These old boats deserve better

0

I’M ALWAYS AMAZED when people selling boats won’t take the time and effort to clean them up a bit before inviting buyers to look at them. I’ve inspected two boats in the past few months, and quite frankly I was disgusted at the state they were in, despite the glowing descriptions in the advertisements.

Admittedly, I’m searching the cheap and nasty end of the boating spectrum. What I want is an inexpensive daysailer/weekender on which I can teach my grandkids to sail. They know the rudiments already, of course, and they’ve taken a few lessons, but I would like to teach them the real stuff that will keep them interested in sailing for the rest of their lives.

In particular, I’m looking for an old Santana 22, simply because I once restored one from a 28-year-old wreck. I discovered all her weak spots and now know where to look for trouble. Over a period of years, June and I sailed her from one and of the Salish Sea to the other, and we were delighted with her performance as a “sport cruiser,” as I called her.

But the two Santana 22s I found for sale on Craigslist last year were simply not worth looking at. One, described as “awesome” and well maintained had a keel that was a mass of rust. There were bits and pieces of mysterious boat stuff strewn all over the main cabin and the forepeak, rust streaks on the paint, ripped and deflated upholstery, aluminum chainplates bubbling with a white encrustation, and a mast support beam that was bowed downward. The other boat was much the same, but it had also suffered the “improvements” of a series of owners with their own lubberly ideas of what a small sloop should look and behave like.

I don’t know how many prospective buyers must have been put off by the state of these boats, but I would have been ashamed to put them on the market in that condition. I know we’re talking about boats that are nearly 50 years old, but I can’t understand why they can’t at least have been kept clean and tidy and smelling sweet. Nobody expects an old boat to be perfect, but to present a boat for sale in such a slatternly run-down condition is an affront to the person expecting the “awesome” boat of the advertisement. It actually hurts me to see good, well-designed boats so badly neglected. There are years of life left in them yet. They surely deserve better.
