A MODEL BOAT.

We need scarcely say that it is not expedient for a boy to attempt to

build a model boat in the same manner as a regular boat-builder

constructs one for actual service. It would be undertaking an

unnecessary amount of labour to lay a keel and form ribs and nail on

planks in the orthodox fashion, because, for all practical purposes, a

boat cut out of a solid block of wood is quite as useful, and much more

easily made.

The first thing you have to do, my young boat-builder, then, is to go

and visit a harbour or beach where varieties of boats are to be found,

and, having settled in your mind which of them you intend to copy, make

a careful drawing, in outline, of its form in four different positions.

First, a side view, as in Figure 1. Then the stern, with the swelling

sides of the boat visible, as in Figure 2. The bow, as in Figure 3; and

a bird's-eye view, as in Figure 4. The last drawing can be made by

mounting on some neighbouring eminence, such as a bank or a larger boat,

or, if that is impossible, by getting upon the stern of the boat itself,

and thus looking down on it. These four drawings will be of great

service in enabling you to shape your model correctly; for as you

proceed with the carving you can, by holding the model up in the same

position with any of the drawings, ascertain whether you are progressing

properly; and if you get the correct form of your boat in these four

positions, you will be almost certain to make a good boat. If, on the

other hand, you go to work without drawings, the probability is that

your boat will be lopsided, which will prevent it from floating evenly;

or crooked, which will tend to check its speed in sailing, besides being

clumsy and not "ship-shape," as the sailors have it.

Figure 1 will keep you right in regard to relative length and depth;

Figure 2 in regard to shape of stern and bulge of the sides; Figure 3

secures correct form of the bow; and Figure 4 enables you to proportion

the breadth to the length.

The next thing to be done is to procure a block of fir-wood, with as few

knots in it as possible, and straight in the grain. The size is a

matter of choice--any size from a foot to eighteen inches will do very

well for a model boat. Before beginning to carve this, it should be

planed quite smooth and even on all sides, and the ends cut perfectly

square, to permit of the requisite pencil-drawings being made on it.

The tools required are a small tenon-saw, a chisel, two or three gouges

of different sizes, a spoke-shave, and a file with one side flat and the

other round. A rough rasp-file and a pair of compasses will also be

found useful. All of these ought to be exceedingly sharp. The gouges

and the spoke-shave will be found the most useful of these implements.

Begin by drawing a straight line with pencil down the exact centre of

what will be the deck; continue it down the part that will be the stern;

then carry it along the bottom of the block, where the keel will be, and

up the front part, or bow. If this line has been correctly drawn, the

end of it will exactly meet the place where you began to draw it. On

the correctness of this line much will depend; therefore it is necessary

to be careful and precise in finding out the centre of each surface of

the block with the compasses. Next, draw a line on each side of this

centre line (as in the accompanying diagram), which will give the

thickness of the keel and stern-post. Then on the upper surface of the

block draw the form of the boat to correspond with the bird's-eye view

(Figure 4, on page 82) already referred to. Then draw _one-half_ of the

stern on a piece of thin card-board, and when satisfied that it is

correct cut it out with scissors; apply it to the model, first on one

side, and then on the other side of the stern-post. By thus using a

pattern of only one-half of the stern, exact uniformity of the two sides

is secured. Treat the bow in the same way. Of course the pattern of

the bow will at first be drawn on the _flat_ surface of the block, and

it will represent not the actual bow, but the thickest part of the hull,

as seen in the position of Figure 3, on page 82. After this, turn the

side of the block, and draw the form represented in Figure 1, page 82,

thereon, and mark _on the keel_ the point where the stem and keel join,

and also where the stern and keel join. This is necessary, because in

carving the sides of the boat these lines will be among the first to be

cut away. The next proceeding is to cut away at the sides and bottom of

the block until, looking at it in the proper positions, the bow

resembles Figure 3, and the stern Figure 2, above referred to. This

will be done chiefly with the gouge, the chisel and spoke-shave being

reserved for finishing. Then saw off the parts of the bow and stern

that will give the requisite slope to these parts, being guided by the

marks made on the keel. In cutting away the upper parts of the bow and

stern, be guided by the curved lines on the deck; and in forming the

lower parts of the same portions, keep your eye on your drawing, which

is represented by Figure 1.

It is advisable to finish one side of the boat first, so that, by

measurement and comparison, the other side may be made exactly similar.

Those who wish to be very particular on this point may secure almost

exact uniformity of the two sides by cutting out several moulds (three

will be sufficient) in card-board. These moulds must be cut so as to

fit three marked points on the _finished_ side, as represented by three

dotted lines on Figure 1; and then the unfinished side must be cut so as

to fit the moulds at the corresponding points. If the two sides are

quite equal at these three points, it is almost impossible to go far

wrong in cutting away the wood between them--the eye will be a

sufficient guide for the rest.

The accompanying diagram shows the three moulds referred to, one of them

being _nearly_ applied to the finished part of the hull to which it

belongs. Thus--(a) represents the unfinished side of the boat; (b) the

finished side; (c) is the mould or card cut to correspond with the

widest part of the finished side, near the centre of the boat; (d) is

the mould for the part near the bow; (e) for that near the stern. These

drawings are roughly given, to indicate the plan on which you should

proceed. The exact forms will depend on your own taste or fancy, as

formed by the variously-shaped boats you have studied. And it may be

remarked here, that all we have said in regard to the cutting out of

model boats applies equally to model ships.

The outside of your boat having been finished, the bow having been

fashioned somewhat like that represented in the accompanying cut, and

the stern having been shaped like that shown in the illustration given

below, the next thing to be done is to hollow out the hull. Care must

be taken in doing this not to cut away too much wood from one part, or

to leave too much at another; a little more than half an inch of

thickness may be left everywhere. Next, fix in the thwarts, or seats,

as in the foregoing cut, attach a leaden keel, and the boat is

completed.

The keel may be formed by running melted lead into a groove cut in a

piece of wood, or, better still, into a groove made in nearly dry clay.

By driving four or five nails (well greased) into the groove before

pouring in the melted lead, holes may be formed in the keel by simply

withdrawing the nails after it is cold.

A mast and sail, however, are still wanted. The best kind of sail is

the lug, which is an elongated square sail--shown in the accompanying

illustration.

Most of our fishing-boats are provided with lug-sails, and on this

account are styled luggers. These boats are of all sizes, some of them

being fifty tons burden, and carrying crews of seven or ten men each. A

picture of a lugger is given on the next page.

Great numbers of fishing-boats may be seen at Great Yarmouth, and all

along the coasts of Norfolk and Suffolk. They are employed in the

herring-fishery, and use nets, which are let down in deep water, corks

floating the upper edges of the nets, and the lower edges being sunk by

leads, so that they remain in the water perpendicularly like walls, and

intercept the shoals of herring when they chance to pass. Thousands of

these glittering silvery fish get entangled in the meshes during night.

Then the nets are drawn up, and the fish taken out and thrown into a

"well," whence they are removed as quickly as possible, and salted and

packed in lockers; while the nets are let down again into the sea.

These boats remain out usually a week at a time. Most of them return to

port on Saturday, in order to spend Sunday as a day of rest. Some,

however--regardless of the fact that He who gives them the fish with

such liberal hand, also gave them the command, "Remember the sabbath

day"--continue to prosecute the fishing on that day. But many a good

man among the fishermen has borne testimony to the fact that these do

not gain additional wealth by their act of disobedience; while they lose

in the matter of nets (which suffer from want of frequent drying) and in

the matter of health (which cannot be maintained so well without a

weekly day of rest), while there can be no doubt that they lose the

inestimable blessing of a good conscience. So true is it that godliness

is profitable for the life which now is as well as for that which is to

come.

A model boat should be rigged with only one mast and lug-sail, or with

two masts and sails at the most. Three are unnecessary and cumbrous.

Each sail should be fixed to a yard, which should be hoisted or hauled

down by means of a block or pulley fastened near the top of the mast.

The positions of these yards and the form of the sails may be more

easily understood by a glance at our woodcut than by reading many pages

of description.

Sprit-sails are sometimes used in boats. These are fore-and-aft sails,

which are kept distended by a sprit instead of a yard. The sprit is a

long pole, one end of which is fixed to the lowest _innermost_ corner,

near the mast, and the other end extending to the highest _outermost_

corner; thus it lies diagonally across the sail. It is convenient when

a boat "tacks," or "goes about"--in other words, when it goes round

frequently, and sails, now leaning on one side, and, at the next tack,

on the other side. In this case the sprit requires little shifting or

attention. But it is dangerous in squally weather, because, although

the sheet or line which holds the lower and _outer_ end of a sail may be

let go for the sake of safety, the upper part remains spread to the wind

because of the sprit.

The best rig of all for a model boat, and indeed for a pleasure-boat, is

that which comprises a main-sail, in form like that of a sloop or a

cutter, omitting the boom, or lower yard, and a triangular fore-sail

extending from near the mast to the bow of the boat or to the end of the

bowsprit--somewhat like a sloop's jib. Both of the sails referred to

may be seen at the part of this book which treats of sloops and cutters;

and they are the same in form, with but slight modification, when

applied to boats.

Racing-boats are long, low, narrow, and light. Some are so narrow as to

require iron rowlocks extending a considerable distance beyond the sides

of the boat for the oars to rest in. Many of these light craft may be

seen on the Thames and Clyde, and other rivers throughout the kingdom.

The larger sort do not require what we may call the outrigger rowlocks.

The "Rob Roy" canoe has, of late years, come much into fashion as a

racing and pleasure boat. Whatever the advantages of this craft may be,

it has this disadvantage, that it can hold only one person; so that it

may be styled an unsocial craft, the company of one or more friends

being impossible, unless, indeed, one or more canoes travel in company.

This species of canoe became celebrated some years ago, in consequence

of an interesting and adventurous voyage of a thousand miles through

Germany, Switzerland, and France, and, subsequently, through part of

Norway and Sweden, made by Mr Macgregor in a craft of this kind, to

which he gave the name of "Rob Roy." Since the craft became popular,

numerous and important improvements have been made in the construction

of its hull and several parts, but its distinctive features remain

unaltered. The "Rob Roy" canoe is, in fact, almost identical with the

Eskimo kayak, except in regard to the material of which it is made--the

former being composed wholly of wood, the latter of a framework of wood

covered with skin. There is the same long, low, fish-like form, the

same deck, almost on a level with the water, the same hole in the centre

for the admission of the man, the same apron to keep out water, and the

same long, double-bladed paddle, which is dipped on each side

alternately. The "Rob Roy" has, however, the addition of a small mast,

a lug-sail, and a jib. It has also a back-board, to support the back of

the canoeman; the paddle, too, is somewhat shorter than that of the

Eskimo canoe; and the whole affair is smarter, and more in accordance

with the tastes and habits of the civilised men who use it.

In his various voyages, which we might almost style journeys, the

originator of the "Rob Roy" canoe proved conclusively that there were

few earthly objects which could form a barrier to his progress. When

his canoe could not carry him, he carried it! Waterfalls could not stop

him, because he landed below them, and carried his canoe and small

amount of baggage to the smooth water above the falls. In this he

followed the example of the fur-traders and Indians of North America,

who travel over any number of miles of wilderness in this manner.

Shallows could not stop him, because his little bark drew only a few

inches of water. Turbulent water could not swamp him, because the waves

washed harmlessly over his smooth deck, and circled innocently round his

protective apron. Even long stretches of dry land could not stop him,

because barrows, or carts, or railways could transport his canoe hither

and thither with perfect ease to any distance; so that when the waters

of one river failed him, those of the next nearest were easily made

available. In conclusion, it may be said that the "Rob Roy" canoe is a

most useful and pleasant craft for boys and young men, especially at

those watering-places which have no harbour or pier, and where, in

consequence of the flatness of the beach, boats cannot easily be used.

It would be an almost endless as well as unprofitable task to go over

the names and characteristics of all our various kinds of boats in

detail.

Of heavy-sterned and clumsy river craft, we have an innumerable fleet.

There are also _Torbay Trawlers_, which are cutters of from twenty to

fifty tons; and the herring-boats of Scotland; and cobbles, which are

broad, bluff, little boats; and barges, which are broad, bluff, large

ones; and skiffs, and scows, and many others.

In foreign lands many curious boats are to be met with. The most

graceful of them, perhaps, are those which carry lateen sails--enormous

triangular sails, of which kind each boat usually carries only one.

_India-rubber boats_ there are, which can be inflated with a pair of

bellows, and, when full, can support half-a-dozen men or more, while,

when empty, they can be rolled up and carried on the back of one man, or

in a barrow. One boat of this kind we once saw and paddled in. It was

made in the form of a cloak, and could be carried quite easily on one's

shoulders. When inflated, it formed a sort of oval canoe, which was

quite capable of supporting one person. We speak from experience,

having tried it some years ago on the Serpentine, and found it to be

extremely buoyant, but a little given to spin round at each stroke of

the paddle, owing to its circular shape and want of cut-water or keel.

Of all the boats that swim, the lifeboat is certainly one of the most

interesting; perhaps it is not too much to add that it is also one of

the most useful. But this boat deserves a chapter to itself.
