The idea prevails among those unacquainted with the sport that, because ice-boats skim along so rapidly over the frozen river, it is therefore particularly dangerous. This, however, is an incorrect conclusion to draw, for ice-boats are so easily controlled that they can be brought to a stop almost instantly, and they answer their helms so rapidly that they can be most easily steered and turned out of danger. As in everything else of this nature, however, the sportsman, whether he be young or old, must use judgment and care in the handling of his machine, otherwise he is bound to come to grief. But such an individual would undoubtedly come to grief on a bicycle or on skates, or even in walking through the crowded streets of a busy city.

PLAN FOR HOME MADE ICE BOAT.

The construction of an ice-boat is the point I want to touch on here, rather than upon the improbability of suffering bodily harm from taking part in the sport. Of course it is always possible to buy an ice-boat, new or second-hand; but it is much cheaper and certainly more pleasing and profitable to build your own craft, and it is by no means a difficult task. The boat proper is a triangular wooden frame, partly covered at the apex or stern. This covering, or deck, is necessary for the accommodation of the crew. The frame is built to rest on three skatelike runners, two of which are at the front—at either end of the base-line of the triangle—and one at the stern, the latter being the rudder. This rudder is controlled by a tiller, similar to the tiller of a sail-boat, and it is with this that all the handling of the machine is done, for the sails are seldom touched after they have once been set.

Many rigs have been tried on ice-boats, but experience has shown that the simple balanced jib-and-mainsail rig is the best. As a rule the jib sheet is set on a traveller, so that no trimming down is required for going about. If it is possible to avoid it, an ice-boat should never be made to run before the wind, because the craft cannot be made to behave well under such conditions. There being no resistance to speak of, such as a cat-boat meets in the water, the ice-boat behaves badly when sailing free, runs up against the wind, and falls back continually. The best plan when sailing one of these machines off the wind is to take a zigzag course back and forth in the general direction of the wind, instead of running directly before it.

The best material for the construction of an ice-boat is oak, but good yellow pine will do for the frame if oak is found to be too expensive. The platform should be built of light pine, with a low railing around the edge. It is well to screw a few cleats and eye-bolts to this deck, to which it may be found convenient to fasten straps and ropes to hold on by when running fast or making turns. I give no proportions for construction, because it is best for amateur carpenters to adapt these to their resources. The general proportionate relation of the various parts of the machine can be easily seen from the diagrams.

The frame of an ice-boat is subject to severe strain, and ought, therefore, to be made as strong as possible. It should be put together with bolts and screws. Nails may be used for the platform, but screws are preferable. The mast should be of pine, and must be rigged with strong stays—of wire, if possible. The bowsprit in the same way. When it comes to the making of the rudder a blacksmith will have to be called in. The tiller and rudder-post will have to be forged of iron, as shown in the diagram, and should be carefully made, because much depends upon their strength and durability. The head of the rudder-post must be squared off, and the tiller fixed firmly upon it. The steering runner, or rudder proper, underneath, is secured to the iron rudder-post by a bolt, and it is advisable to slip a large iron washer over the post to give it a smooth bearing.

RUNNER AND BLOCKS.

For the runner shoes I should recommend soft iron. This becomes very much heated, to be sure, when the boat is running, but the soft metal chills rapidly as soon as the machine comes to a stop. This alternate heating and chilling soon give the runner's edge a degree of hardness fully equal to that of steel. (Let me caution novices at ice-boating against touching their runners, for the metal becomes so heated that it can inflict painful burns.) The runners proper—that is, the wooden part before the metal shoe is put on—should be cut of stiff, heavy oak. They should be carefully bored, and attached to the frame with bolts. The blocks that hold the two forward runners should be firmly bolted to the forward plank of the frame—the one that forms the base of the triangle—and set so as to hold the runners firmly. The iron shoes are screwed to the runners. The metal must previously be drilled, and the screws which hold the shoes to the wood must be counter-sunk so that their heads may not touch the ice.
