HOW THEY ARE BUILT, RIGGED AND HANDLED.
BY CHARLES LEDYARD NORTON.
ONa rocky promontory of the Hudson River, a few miles above Poughkeepsie, there stands, half hidden by the foliage in the summer, a long, low, neatly painted structure instantly suggestive to the nautically inclined of boats and their belongings.
But there is an unaccountable lack of the familiar characteristics of such localities. Even in midsummer there are few, if any, boats anchored in the cove, or hauled up on the shelving rock that serves in lieu of a beach. Through the open doors of the boat-house one may, perhaps, see certain varnishing and rigging operations under way. There are bundles of sails, coils of rope, rows of blocks, and long, curiously curved spars resting upon racks—long enough they are to serve as topgallant-yards for an old-fashioned man-of-war, but no ordinary sailorman would see any use for them with their nautically impossible curves and angles, and their unfamiliar and unshipshape attachments of galvanized iron.
This boat-house, however, is the headquarters of a yacht club that stands easily at the head of its class in all the world; but its fleet of racers is dismantled and laid aside in summers when other yachts are in the height of their glory. This fleet goes into commission only when the floating fields of new ice are fast welded together, and the river surface is solid from the Highlands to the Mohawk.
The Hudson River is by no means the only club, though it may not unfairly be designated as the leading one. At the neighboring towns of Poughkeepsie, New Hamburg and Newburg, and up stream at Hudson, Athens, Saugerties, Albany, and elsewhere, are other associations, with fleets of yachts always eager to try conclusions with their down-stream rivals. Poughkeepsie, and its immediate vicinity, however, has always been, and is likely to remain, the headquarters for ice-yachting.
This is due to several favorable conditions, natural as well as artificial. The river narrows and becomes tortuous at the Highlands—about forty miles from the sea—and this natural obstacle largely determines the permanency of ice in the river above. In a large stream the ice rarely forms across from shore to shore in a single night. It freezes in bands and patches, which become detached from the shore and float up and down with the tide until they become jammed and frozen together. North of the Highlands, too, the average winter temperature is considerably lower than it is to the southward, and sharp frosts come earlier and stay later. The beautiful and picturesque banks, moreover, have since early colonial times proved attractive to lovers of the country, and the riverside is for many miles almost continuously occupied by residents who have abundant means and leisure for such recreations as suit them best. Again, the great harvest field of the Hudson River ice-crop finds here its southernmost limit. At this point in the stream the admixture of sea-water renders the ice more or less unmarketable, and the ice-yachtsmen are therefore not so likely to be interfered with by the armies of men who are set to work by the great companies as soon as the ice is thick enough to pay for cutting and storage.
It is proverbial that no sooner is a good surface formed for ice-yachting than it is hopelessly buried under a shroud of snow; but here again nature comes to the rescue, for the latitude is far enough south to render alternations of frost and thaw probable all through the winter. Accordingly the white surface soon becomes streaked with gray, and ere long the yachtsman looks out of a morning and sees his highway once more practicable for steel runners.
This year engineering science has arrayed itself on the side of the yachtsman, and has built two huge piers in the river at Poughkeepsie. Primarily these are intended for the new cantilever railroad bridge, but incidentally they are welcomed by the winter-sailing clubs, because they will undoubtedly keep the ice in the river longer than it has heretofore been in the habit of staying. This is highly important in their eyes, for not infrequently there are cold “spells” in March which render the ice available for good sport, provided it could be held in position long enough tobe temporarily re-frozen and prevented from floating away down stream on the ebb tide.
Despite all these favorable conditions, however, the goddess who presides over the destinies of ice-yachting is but a coy and fickle divinity. Sometimes she vouchsafes to her devotees not more than a day or two of sailing in an entire winter. Often she limits her favors to ten or fifteen days, and only at rare intervals does she smile upon them for thirty days, all told. The ice-yachtsman may, therefore, plume himself upon being the most select and exclusive of all sportsmen. He cannot, if he would, spend very much timeen voyage, so he makes up for it as well as he may by contriving and perfecting all the details of his craft during her hours of enforced idleness. The result is that he has evolved a fabric that is a marvel of construction, adapted for lightness and strength in a wonderful degree.
Many of our readers have never seen an ice-yacht, but probably most of them have seen and made a common diamond-shaped kite—the simplest and easiest form of kite known to ingenious boyhood. This frame is in its general principles of construction identical with that of the modern ice-yacht, as shown in the working plans published herewith. The cross-piece corresponds with the runner-plank, the upright represents the center-timber, and the cord that passes around the whole is identical with the side-stays. (See Fig. 1.)
It is only necessary to set up a mast at or near the intersection, rig sails upon it, attach some kind of runners to the ends of the runner-plank and to the long or aftermost end of the center-timber, and you will have a very passable model, constructionally speaking, of the modern ice-yacht. Magnify it a hundred-fold, substitute wire-rope with turn-buckles for the side-stays, fit the timber ends with cast-metal caps, bolt everything together with cunningly contrived fittings, mount her upon a set of hardened iron runners, equip her with a “tailor-made” suit of sails, launch her on reasonably smooth ice, and, given a twenty-mile breeze, she will carry you forty miles, or maybe sixty miles, an hour, if you know how to make her do her best.
It may be remarked in passing that very pretty sport may be had with model ice-yachts, constructed somewhat after the manner indicated. Pieces of tin or sheet-iron will do for runners and steering-gear at a pinch, and if the sails are moderate in area and the center-timber tolerably long, so that ballast can be suitably adjusted, she will go like a witch and skim over a mere veneering of ice to the admiration of all beholders. There are always several days at the beginning of winter before the ice is available for skating, when model ice-yachts might be made to do duty instead of the sticks and stones with which impatient boyhood usually disports itself, thereby ruining the ice for the legitimate pastimes of colder weather.
In the regions where the ice rarely becomes thick enough for satisfactory skating, these little ice-yachts may easily afford a deal of not altogether unprofitable amusement. Model yachts have not as yet gained much of a foothold in the nonfreezing United States, but in England, where there are prosperous clubs almost everywhere, even in Hyde Park, in the heart of London, the conditions are very favorable. Sails and rigging are all ready and need only to be mounted upon a suitable frame with runners, steering gear and adjustable ballast. The average Englishman may probably regard this suggestion as unwarrantable, because ice-yachting is wholly beyond his range of experience, but if once he tries it he will find that it opens up possibilities of seamanship not dreamed of heretofore, and he will cover the frozen Serpentine with miniature fleets that will rival in beauty and vastly excel in speed those that dance over its ripples during the summer months.

FIG. 1.—A KITE-FRAME FOR AN ICE-YACHT.
In its main features the Hudson River ice-yacht now closely approaches perfection. Improvements will, of course, be made from time to time in the minor details of rig, and occasionally some phenomenally fast boat will be built, the secret of her speed remaining perhaps, in some degree, unexplained.
A few years ago the lateen rig was simultaneously adopted by the Hudson River and Shrewsbury (N. J.) clubs, and for a time it bade fair to supersede the jib and mainsail boats that had long held the championship pennant. Several very large lateen-rigged yachts were constructed, notably theScudof the Shrewsbury, and theAvalancheof the Hudson River Club. Experience has shown, however, that craft of that size and rig are phenomenally fast only when the wind rises to No. 70 of Beaufort’s scale, that is to say, something nearly approaching a full-grown hurricane. With such a wind the big lateens are undoubtedly very fast, but the rarity of such conditions leaves them in the lurch on ordinary racing days, and it is by no means certain that even in a hurricane they are sure to win when pitted against a jib and mainsail. At all events, some of the large lateens have been altered to the sloop rig, and their owners are not disposed to try back.
On small or moderate sized yachts, however, the lateen is an admirable rig, and in average racing weather such boats not infrequently distance their larger competitors. In this connection it may be well to compare the respective weights of the two rigs as taken by Mr. John A. Roosevelt, Commodore of the Hudson River Club.

It is seen, therefore, that the lateen outscales her rival by about 575 lbs., the two boats being nearly the same size. Theoretically, theAvalanchehaving only a single sail—and that capable of being set almost as tight and flat as a drumhead—should out-point and out-foot anything of her size, but practically the extra weight hinders more than the better fitting canvas helps her.
The “cat-rig,” too, has been tried, but without the good results anticipated, and a sharpie rig has, it is said, done fairly well with a small boat on the Shrewsbury.
It may be confidently stated that the sloop rig is the safest to count upon for allround work, particularly in the largest-sized boats. In boats of the second and third class the lateen may be used with a chance, not altogether assured, of superlatively good results.
It is not likely that ice-yachts will ever be built larger than the present, theAvalanche,Icicle,Northern Light,Scud, and their class,i. e., about fifty feet long, and spreading something like 600 square feet of canvas. To sustain such a boat requires comparatively heavy ice; to drive her at a high rate of speed calls for a living gale of wind, and to tow her home when becalmed, or collect her scattered fragments should she chance to be shipwrecked, is a work demanding a large store of patience and endurance. In average blustering wintry weather, with a wind not to exceed, say, twenty-five miles an hour, boats of the second class stand a very fair chance of beating those of a larger spread and heavier weight.
The art of sailing an ice-yacht issui generis. It is, indeed, of comparatively modern origin. A generation ago sheets were started on an ice-yacht when running free, much as they are in an ordinary sailing-boat, and the singular properties of the close-hauled sail were not understood. The modern ice-yachtsman never slacks away his sheet except, perhaps, when he wants to turn a stake with certainty, or when the ice softens. Given a hard surface and a stiff breeze, he will outrun the wind in any direction.
One who hears this paradox stated for the first time may be pardoned for incredulity, nor is it easy in all cases to make clear the possibility of such a feat. A very large majority of intelligent people when confronted with the proposition, simply say that it is impossible and absurd, and are hardly convinced when they actually see an ice-yacht running straight down the wind, with her pennant streaming out astern. To yachtsmen. it had been known for several years that a comparatively light wind would send ice-yachts ahead of the fast express trains on the Hudson River Railroad. After a time the mathematicalexperts heard of it, and they said it could not be so; they took their little slates and proved their position to the satisfaction of all properly constituted scientific minds. But this did not prevent the yachtsmen from sailing faster and faster, and presently other mathematicians rose up and demonstrated the contrary of the proposition, thereby showing, for the ten-thousandth time, that all save the truth can be proven by figures.
FIG. 2.—THE SAILING PARADOX.
FIG. 2.—THE SAILING PARADOX.
The fundamental principle of sailing an ice-yacht faster than the wind may be readily demonstrated by means of a very simple mechanical device.
Let A, E, B, F be an open frame, A-B a wire stretched diagonally from corner to corner, and G a ring running upon the wire. C-D, another wire, reaches from end to end of the frame, passing also through the ring G at the intersection of the wires. This second wire (C-D) is movable back and forth between A-F and E-B, and parallel to them. It is evident that when C-D is moved the ring G will slide along both wires, and that while C-D is passing from A-F to E-B, G will slide from A to B—twice as far, that is, as the distance traversed by C-D, the moving agent.

SAIL PLAN OF A MODERN ICE-YACHT.
Now, suppose G to be an ice-yacht; let the movement of C-D across the frame represent the direction and velocity of the wind and the diagonal A-B the distance to be traversed. The ice-yacht G moves twice as far, that is to say, twice as fast as does C-D (the wind) that drives it. Such is, perhaps, as plain a statement of the conditions as can be devised. In practice the elements become more complicated. Let Fig. 3 represent a section of frozen river, with the wind blowing across it in the direction indicated by the arrows. Applying the principle shown in Fig. 2, an ice-yacht may run from A to B while the wind is moving across the river from A-F to E-B. It is not the purpose of this paper to go into the logistics of sailing in general, but any one who can sail a boat will see at a glance, that with the wind as shown in Fig. 3, an ordinary boat would sail nearly or quite as fast from C to D, orfrom E to F, as she would from A to B. The same rules apply, of course, to an ice-yacht, but with this important difference, while an ordinary sailing-boat meets with increasing resistance from the water the faster she goes through it, an ice-yacht meets less and less frictional resistance from the ice the faster she goes over it. Again, if she is pointing more or less toward the wind (as on a line from E to F), she increases the apparent force of the wind by her own motion. The only considerable resistance is that offered by spars, rigging, etc., in passing through the air, and this is trifling when compared with her large sail area, and the propulsive energy of even a moderate breeze.
FIG. 3.—THE SAILING PARADOX IN PRACTICE.
FIG. 3.—THE SAILING PARADOX IN PRACTICE.
In sailing an ice-yacht there is none of the vexatious handling of ropes unavoidable in an ordinary sailing-boat. The sheets usually take care of themselves in going about, and the steersman has only to move his tiller a little to starboard or port to secure instant obedience and an eagle-like swoop of the yacht in the desired direction. In high winds, however, the yacht is apt to lift her weather runner clear of the ice, upon which she at once becomes unmanageable and must be brought down to her bearings as soon as possible. If properly balanced she should shortly do this of her own accord, but during the few seconds when she has the bit between her teeth she may do untold mischief.
The astonishing rapidity with which an ice-yacht under control may be handled was well instanced last winter in an encounter between thePolarisandArrow, as indicated in the diagram, Fig. 4. ThePolariswas running dead before the wind, heading to pass a space of open water where ice-cutters were at work, when her steersman became aware of theArrowapproaching on his starboard hand at a fearful rate of speed, but with her weather runner in the air, and evidently with the bit between her teeth. A collision was imminent, for thePolariscould not bear away in either direction; on one side was open water and on the other was theArrow, too near to be passed astern. Under the circumstances it was instinct rather than a process of reasoning that led Commodore Roosevelt to jam his helm hard a-starboard and send thePolarisspinning on her center, making a complete revolution almost within her own length (see Fig. 4). She did it, and was on her former course again almost before any one knew what had happened, her jib-boom barely clearing the after leach of theArrow’smainsail as she passed astern of her. Such a gyration as this is justifiable only in extreme cases, for of course everything is subjected to a sudden and tremendous strain, and if nothing gives way it speaks well for the perfection of equipment.
Sometimes an ice-yacht will perform this maneuver on her own responsibility and without an instant’s warning, and this is especially true of the smaller class of lateen-rigged boats. With them, however, damage is less likely to result, as the strains are proportionately less severe.
Sailing on the wind is a comparatively simple matter, though, of course, where a number of boats are breaking tacks, as in a thrash to windward on a regatta day, a quick eye and a steady hand are indispensable if collisions are to be avoided and the most made of every turn.
Running down the wind, however, calls for the more skillful seamanship, and involves a closer calculation of chances.Not many years ago, when a fleet of ice-yachts sailed down the wind, it was a straight run with lifted sheets, but after a while some bright fellow discovered that by putting his boat on the wind at her very best point for speed, she would in a few seconds attain a maximum velocity. Then, bearing away, she would run sometimes for several minutesthroughthe wind, her pennant flying out astern, and she sliding past her free-sailing competitors at an astonishing rate.
FIG. 4.—A CLOSE CALL.
FIG. 4.—A CLOSE CALL.
Fig. 5 roughly shows the comparative courses of two ice-yachts, A running dead to leeward and B tacking after the method described. The proportions between the tacks across the wind and the runs through it cannot be preserved on so small a map; but it is evident that B traverses a far longer course. That she invariably beats A, other things being equal, is the unanimous testimony of all practical ice sailors. In other words, if a balloon could be persuaded to drift down the wind at a convenient height above the ice, B could let it have a fair start, and could, if properly handled, sail completely around it in a run of two or three miles.
This “proper handling,” however, is not so simple as it seems. It involves an intimate knowledge of and sympathy with one’s boat. Her best point of sailing varies with every variation in the force of the wind, and her skipper should know by instinct exactly when she is doing her very best under existing conditions. She must not be forced so that she will lift her weather runner clear of the ice, for the moment that runner lifts the grip of the lee runner weakens, and the yacht is in danger of making leeway. She must not be turned too sharply, for the rudder checks her headway, and so does the lateral resistance that she encounters while changing directions. A knowledge of the course is of vital importance. Instead of the currents and tide-rips of summer, the winter yachtsman must be familiar with the “windrows,” air-holes, cracks, ice-imbedded drift-wood, and the like, that beset his course. After every storm these are liable to change and new obstructions from similar causes likely to appear. Hence every tack must be calculated to a nicety, so that the next change of direction can be made to the best advantage.
When running for the stake it is important to gauge headway so that the turn can be made without being carried too far beyond the mark; and here again a personal knowledge of the boat and her whims is indispensable for nice seamanship. In the excitement of the moment one may readily lose control, and it is said to be a good plan to slack away the peak halyards a trifle just before rounding. This enables the rudder to act with certainty, and as soon as the turn has been made the halyards can be again hauled taut. This operation necessitates the best modern appliances in the way of hoisting-tackle, for the halyards all lead aft to the “box,” and one man should be able to slack away or haul taut with one hand. Then, of course, there are all the devices known to sailing experts intensified a hundred-fold by the altered conditions.
Courses down the WindFIG. 5.
FIG. 5.
An absolutely even start can always be had since the contestants can be held at anchor till the signal is given, though, of course, the windward position gives an advantage. Once under way seamanship and knowledge of the course begin to tell, and bold maneuvering may quite as often win a race as in the slower evolutions of regular sailing craft. The swiftness with which any plan can be executed renders the game extremely exciting. One sees an opponent making a short and seemingly unnecessary tack. The natural results must be comprehended instantly or, peradventure, one may find one’s self presently forced to yield the right of way when every second is of the last importance. It is jockeying, perhaps, but when one knows that by crowding adangerous rival a trifle he will be forced to tack a mile farther on by an insurmountable windrow, one were more than mortal to resist the temptation. It calls for quick thinking and equally quick action to sail an ice-yacht successfully and well in a modern regatta; but the excitement is of the wildest description, and all the accessories are fascinating in the extreme to one who has robust health and does not care a rap for exposure in a northern midwinter.
Our frontispiece is from an instantaneous photograph which caught theNorthern Light(holder at the time of the Challenge Pennant) just as she was rounding the home stake, off Poughkeepsie, on Valentine’s Day, 1887. She was probably moving at the rate of twenty miles an hour when the picture was taken. The sleet thrown up by her lee runner can be seen flying off astern. Her weather runner was, in fact, just clear of the ice at the moment, though so slightly as to be imperceptible in the picture. This is probably the best photograph of a moving ice-yacht that has ever been taken.
Every year sees improvements in fittings and rig. The “Haggarty hoist” is now used on the mainsails of the best boats instead of the ordinary mast-hoops. This hoist consists of a series of metal clamps attached to the luff of the sail and engaging a wooden cleat shaped like a T-rail and fastened vertically to the after-side of the mast.
To secure a better “set” the luff of the sail is no longer doubled over on itself, but instead, a canvas binding is sewed on. This gives three thicknesses of canvas instead of five thicknesses, as was often the case under the old system, and, consequently, the sail stretches along the mast, where the greatest hoisting strain falls, and where any inequality is most readily taken up without causing wrinkles elsewhere. The elliptical box, with its comfortable cushions and its central hand-rail for the passengers to grasp in case of need, is suggestive of luxury but in itself it is largely delusive, for no position is less endurable than a half-reclining one with the head raised, as was formerly unavoidable. To render the sitting position possible the iron tiller is now given an upward curve, so that the steersman can sit with his legs across the center-timber, the tiller swinging freely above his knees. This posture, however, necessitates some sort of a backboard, and the best appears to be an upholstered iron frame, as shown in Fig. 6.
FIG 6.—A BACK-REST.
FIG 6.—A BACK-REST.
The flat extensions, A A, pass under the cushion, and a firm back and brace is thus supplied. Another device is to make the central portion of the side of the box higher than the rest, with a narrow cushion to fit, effecting the same end. This matter of cushions is not mere luxury. The rapid passage of the runners over any save the very smoothest of ice produces a jarring motion that speedily becomes unendurable wherever the person rests against a hard or angular surface. In previous articles it has been suggested that stout chair-seats, with arms and back, might be adjusted to the center-timber in connection with a foot steering-gear, similar to those used in canoes. Such seats could be fastened anywhere on the center-timber by means of thumb-screws, thus moving the weight forward or aft according to the special conditions of wind or weather.
The season for ice-yachting in the latitude of New York rarely begins before January and often holds off until February. The daily morning papers always mention the condition of the ice on the preceding day, and by taking an early morning train one may easily reach the sailing-ground by noon or shortly after. The weather, in New York is no criterion of that north of the Highlands. It is often raining on the coast when the sky is clear and the weather fine in the interior. When, therefore, good ice is announced by the papers, the correct thing to do is to take the next train to Poughkeepsie, irrespective of weather. You may be disappointed, for wind and temperature are proverbially fickle; but if you have reasonably good luck you may see the finest ice-yachts in the world, and learn by personal observation how they are managed.
