clincher construction, but with the development of fishing grounds farther
from the coast came the need of better seagoing qualities. The model shows
a partially- decked carvel-built boat with large central opening, and covered
lockers placed aft below the deck level. The single mast, carried well
forward, is fitted with a large dipping lug- sail ; a mizen-mast is used with
larger boats.

Length, over all, 25 ft. ; breadth, 8-25 ft.

Exhibition, 1883. N. 1611.

This is a carvel-built boat, with a sharp stern and two drop keels ; she
also has a central well in which to store live fish. One mast is provided,
carrying a foresail and a sprit mainsail ; the boat pulls four oars and is used
for seine fishing.

Length, 35 ft. ; breadth, 8' 75 ft. ; depth, 4 ft.

475. Rigged model of felucca. (Scale 1 : 16.) Lent by H. C.
BucknaU, Esq., 1904. N. 2351.

This type of vessel, distinguished by its rig of single lateen sails on two
or more masts and the addition of poles and oars for use in calms, appears
to have been developed on the Mediterranean coasts.

The particular example represented, known as a falua the Portuguese
form of the word felucca was very general on the Tagus before the intro-
duction of steamers, but is now disappearing ; such boats were, however, the
only means of transport for passengers and goods between Lisbon and ports
on the south bank of the river. The vessels are constructed locally, of pine ;
the majority are half-decked to the mainmast, and have the after part decked
over for about 12 ft., but the larger ones are, as shown by the model, whole-
decked. The sails are furled by means of a rope manipulated by a man at
the masthead, assisted by another below. The crew consists of five men.

Carrying capacity, 12 tons ; length over all, 49 '4 ft. ; breadth, 13' 75 ft. j-
depth, 6 16 ft. ; length of mainmast, 31 6 ft. ; length of foremast, 27 8 ft. j
area of mainsail, 580 sq. ft. ; area of foresail, 476 sq. ft.

476. Rigged model of Spanish felucca. (Scale 1 : 32.) Re-
ceived 1910. N. 2548.

This represents a two-masted Spanish coasting vessel of the felucca type.
It has an elliptical stern and a high, ornamented stem-piece. The two
lateen-rigged masts are placed well aft in the vessel, and a bowsprit is used
for the head sails.

Length, 40 ft. ; breadth, 11 ft.

Three views of feluccas on the Lake of Geneva are also shown.

477. Built model of " Rob Roy " canoe. (Scale 1 : 2.) Lent
by Messrs. R. J. Turk and Sons, 1908. N. 2494.

This represents, in its principal features, a form of decked canoe which
came into general use in 1865, largely as the result of a remarkable journey
of about 1,000 miles, chiefly on the lakes and rivers of Central Europe, made
by Mr. J. Macgregor, M.A., in a vessel of this type designed by himself.
Published narratives of this, and subsequent journeys of a similar character,
led to the formation of canoe clubs all over the world and the construction
of large numbers of these craft.

As the original " Rob Roy " canoe was intended for easy transport on
land as well as for use indifferently on sea, lake, and river, it embodied many
of the characteristics of the Eskimo " kayak " (see Nos. 528 and 529).
Wood, however, was used in its construction : English oak for the keel and
sides, with cedar for the deck ; an oscillating backboard was added to the
deck aperture with an easily detachable waterproof cloth around the occupant
when seated : a single mast, stepped on the fore side of the aperture, with a
dipping-lug sail and jib, was also used ; the canoe was propelled and steered
by a double-bladed paddle. Modifications for racing and ordinary river work
were subsequently made in the original design.



142

The example here shown was made by Messrs. Turk and Sons and is fitted
-with two masts and dipping-lug sails ; it has also a rudder with double yoke
and lines, by means of which the steering may be effected by the occupant's
feet.

Ordinary travelling canoes of this type have the following principal
particulars : Length, 12 to 15ft.; breadth, 2" 5 ft.; draught (with 10 Ib.
of luggage), 5 in. ; total weight, 70 to 80 Ib. Double-ended paddle, 7 ft.
long.

478. Rigged model of S.S. " Rob Roy." (Scale 1 : 24.) Lent
by Messrs. A. G. Gifford & Co., 1882. N. 1569.

This ketch-rigged steamer was built at Leith, for line and net fishing.

She is constructed of wood, but has an iron bulkhead covered with non-
conducting cement, dividing the hold from the engine and boiler space,
which is placed as far aft as possible. The hold is fitted up with fish boxes ;
the crew are accommodated forward. The mainmast is fitted in a tabernacle,
to enable it to be lowered ; the sails set are jigger, mainsail, foresail, and
jib.

The engines are of the two-stage expansion, inverted type, and drive
a single screw which gives a speed of 8 knots. Steam at 90 Ib. pressure is
supplied by a vertical tubular boiler.

483. Whole model of transport boat. (Scale 1 : 12.) Be-
queathed by Miss. M. A. Peek, 1906. N. 1030.

This was designed by Mr. Wm. Ladd, of Deptford Dockyard, for the
disembarkation of troops, horses, and field guns in the Crimea, 1854-6.

It consists of a platform supported on two flat-bottomed floats, and
provided with stanchions carrying protecting ropes. A projecting extension
of the platform is hinged, so that it can be lowered for use as an incline in
disembarking. The floats are special boats, but can be used for other
purposes ; their dimensions are : length, 40 ft. ; breadth, 12 '5 ft. ; and
depth, 4 5 ft.

484. Whole model of the obelisk ship "Cleopatra." (Scale
1 : 24.) Presented by John Dixon, Esq., 1879. Plate VI.,
No. 4. N. 1520.

This vessel was built at Millwall in 1877, from the designs of Mr. Dixon
and Sir B. Baker, for the conveyance to England of the obelisk known as
" Cleopatra's needle," presented to the British nation by the Viceroy of
Egypt, Mehemet Ali, in 1820. The cost of the vessel and its transport
were defrayed by Sir Erasmus Wilson.

The " Cleopatra " was a wrought-iron cylindrical pontoon, tapered at
each end to a vertical edge, and furnished with diaphragms 10 ft. apart,
which with suitable elastic packing supported the obelisk. The plates
comprising the pontoon were 375 in. and 4375 in. thick, and its weight
was 60 tons. The obelisk is 66 ft. long, and 8 5 ft. square at the base,
tapering towards the top ; it was placed with the base about 20 ft. from
the bow and the apex close to the stern, which was fitted with a rudder.
On the top and near the centre was a deck-house with accommodation for
three men with a wheel in the fore part. There was a long hurricane
deck above the house and a short mast with two sails surmounted the
whole. The vessel was perfectly watertight, and sealed, the only means
of access being a man-hole door in the floor of the deck-house.

In removing the monolith, a short length of it was first cleared, by
excavation of the sand (in which it had lain for over 20 centuries), and
the corresponding part of the pontoon built around it, and a bearing



144

diaphram fitted, then another length, and so on until the whole was
enclosed. "When completed the cylinder was lagged with 6-in. planks for
a length of 12 ft. at either end, to protect the iron skin from injury, and
then rolled down a slope into the water, and towed to a dry dock, where the
deck-house and bilge keels were added. She was then towed by the S.S.
" Olga " with a wire cable, a quarter of a mile long, at the rate of 7 knots
an hour. Owing, however, to heavy weather in the Bay of Biscay, she was
abandoned, but was afterwards picked up by the S.S. " Fitzmaurice," and
taken into Ferrol, from whence she was towed to England.

The obelisk was placed 4 5 in. below the centre, which gave a meta-
centric height of 10 in. and a period, allowing for the bilge keels, of 6 seconds,
or 10 double rolls per min.

Actual displacement, 270 tons ; possible displacement, 405 tons ; length,
92 ft. ; diameter, 15 ft. ; draught of water, 9 ft. ; weight of obelisk,
160 tons ; ballast, 30 tons.



LIFE-BOATS.

485. Whole model of life-boat (1804). (Scale 1:12.) Lent
by James Young, Esq., 1883. N. 1589.

This represents a non-capsizable life-boat, probably built in 1804, by
Messrs. H. S. Edwards and Sons, of Howden-on-Tyne. Air cases on the sides
and at bow and stern are indicated, otherwise there is no detail.

486. Photographs of model of Brighton life-boat. 1841.
Received 1896. N. 2098.

This life-boat was built at Hove in 1840 for the beach at Brighton by
Mr. Golding. The form is that usually given to whale boats sharp at both
ends to row in either direction ; she was built of elm plank and copper-
fastened, the gunwales rise in a hollow curve giving a sheer of 2 ft. above
the centre at either extremity. The sides were fitted with lockers, 14 in.
wide at the top and sloping upwards from the thwarts to nearly the gun-
wales edge ; these were filled with 3 to 4 cwt. of Farostone cork. The cork
sides extended to within 3 5 ft. of either end ; the ends were decked and
fitted with bulkheads enclosing air-tight copper canisters. The boat pulled
four oars, each 16 ft. long, single banked, and six, four of which were 13 ft.
long, double banked, with the addition of one 17 ft. long, for steering.
Thole pins and grummets were found preferable to rowlocks, as securing the
oars in case of accident. An iron crutch was fitted to either end for steering,
while the other side had a cleat and rollers for kedging the boat through
surf. Two life-buoys, consisting of two cork globes 11 in. diameter, with
20 in. between them, were slung under the centre thwarts.

Her leading dimensions were : Length, 22 5 ft. ; breadth, 6 5 ft. ; depth,
2-6 ft.

487. Whole models of life-boats. (Scale 1 : 8.) Lent by G.
Turner, Esq., 1864. N. 1037.

These were designed by Mr. Turner, of "Woolwich Dockyard, to compete
for the premium of 100 guineas offered by the Duke of Northumberland in
1851 for the best type of life-boat.

They are constructed of wood and have flat bottoms with fine bows and
sharp sterns. Both bow and stern are fitted with removable air chambers,
recessed in the middle ; air chambers are also formed under the thwarts.
Apertures are provided to discharge any water shipped. The larger boat is
fitted to pull 16 oars double banked, and has two masts on which she would
probably carry two lug sails ; the smaller boat pulls five oars.

488. Whole model of life-boat "Excelsior." (Scale 1 : 9'6.)
Lent by J. E. Teasdel, Esq., 1896. N. 2077.

This form of life-boat, which has been adopted at Yarmouth and several
other stations on the Norfolk and Suffolk coasts, was introduced about
1840 by "William Teasdel. It differs from the more generally adopted
construction in that it is not self-righting if capsized ; but it is claimed
that, as none of these boats have ever upset, the elevated air chambers that
are necessary with a self-righting boat are an unnecessary obstruction ; also,
that when suitable air chambers and metal ballast are provided a wide boat
cannot capsize.

In the boat represented the stability is assisted by an iron keel weighing
one ton, together with a ballast tank capable of holding four tons of water.
The air chambers, which extend along the side of the boat and to the bow
and stem under the level of the thwarts, have a capacity of 320 cub. ft., and
a buoyancy of 9 tons ; an outside strake of watertight compartments, in
lengths of 3 ft., built of light wood and covered with cork and canvas, gives
an additional floating power of 3 tons in a position in which it greatly
assists the stability. The floor is fitted with 12 delivery valves, 4 in. diam.,
for discharging any water shipped.

The boat carries two masts, and is fitted for 10 oars, double banked ;
above the gunwale is a rope rail carried in iron stanchions.

Length, 43-2 ft. ; breadth, 12 ft. ; depth, 5 -6 ft.

489. Whole model of life-boat. (Scale 1 : 12.) Received
1896. N. 2075.

This design by Mr. William Teasdel, which represents a boat built for
the heavy surf at Palling, Norfolk, was awarded a prize at the 1851
Exhibition.

The boat is clincher-built, and has considerable sheer ; there are large
air chambers at the bow and stern and along the sides, in addition to an
outside strake of cork. The keel is of iron, and there is a central ballast
well 7 ft. long, 2*5 ft. wide, and 1*5 ft. deep, with perforated iron sides.
She is fitted for 12 oars and two masts.

Length, 36 ft. ; breadth, 10 '5 ft. ; depth, 3'3 ft,



490. Whole model of life-boat. (Scale 1 : 9 '6.) Lent by
J. E. Teasdel, Esq., 1896. N. 2074.

This represents a boat built in 1851 by Mr. William Teasdel, for the
Duke of Northumberland, who stationed it near Hauxley and Warkworth.

She is clincher-built of oak, with low air chambers along the sides and in
the bow and stern, while there is also a high chamber at the bow and stern,
extending, however, only part of the width, so as to leave both ends of the
boat accessible. There is also an external cork strake, and stability is given
by a heavy iron keel. She is fitted for 10 oars, and has two masts.

Length, 32 ft, ; breadth, 10 ft. ; depth, 4-5 ft.

491. Whole model of "Nautilus" life-boat. (Scale 1 : 9 '6.)
Lent by J. E. Teasdel, Esq., 1896. N. 2078.

This represents a design by Mr. William Teasdel, for a life-boat or surf-
raft. The sides are planked, the floor is formed of open gratings, while
buoyancy is given by air chambers in the bow, stern, and between the
thwarts ; in addition there is a large outside strake composed of cork. The
air cases are of 84 cub. ft. capacity, and there are 20 cub. ft. of cork, giving
a combined supporting power of 3 tons.

Length, 24 ft. ; breadth, 9 ft. ; depth, 2-5 ft.

492. Whole model of surf boat. (Scale 1 : 12.) Lent by
J. E. Teasdel, Esq., 1896. N. 2076.

This boat is clincher-built, has an iron keel, and a cork outside strake.
Low air chambers are provided throughout the length under the thwarts
with others at each end above the thwarts. There would be 12 oars and two
masts.

Length, 32 ft. ; breadth, 11 ft. ; depth, 3 5 ft.

493. Whole model of life-boat. (Scale 1 : 16.) Received
1896. N. 2073.

This represents the Lowestoft boat and its carriage, designed by Mr.
William Teasdel.

The model is clincher-built, with a heavy iron keel ; it is fitted with
low air chambers extending from the bow to the stem along the sides
under the thwarts, and there is a cork strake all round on the outside.
She is fitted with 10 valves for discharging any water shipped ; she carries
14 oars double banked, and three masts with dipping lug sails.

She is mounted on a two-wheel transporting carriage, which may also
serve as a launching way.

Length, 34 ft. ; breadth, 9 3 ft. ; depth, 4 3 ft.

494. Life-boat carriage and limber. (Scale 1 : 19 '2.) Lent
by J. E. Teasdel, Esq., 1896. N. 2081.

These were constructed by Mr. William Teasdel for carrying to the
neighbourhood of a wreck the life-boat and Manby's life-line mortar,
together with various stores. The boat is earned on a slip way that is
suspended from the axle of a pair of road wheels 15 ft. diam.

495. Whole model of life-boat. (Scale 1 : 18.) Lent by
John Coryton, Esq., 1858. N. 200.

The features of this design were patented by Mr. Coryton in 1851 and
subsequently somewhat further developed.

At one end the boat is wedge-shaped, with the edge vertical, while at the
other end the shape resembles a shallow and flat stern. When ordinarily
sailing the wedge or " vertical wave line " end was in front, while when
running before the wind the positions are reversed, a principle that is
embodied in some of the Burmese and Chinese boats.

The lower part of the boat was to have been of iron, with a metal
keel, while the upper parts were to have been of wood ; the seats were to
have been fitted with cork, with air compartments at the narrow end. Pro-
pulsion and steering were to have been performed by two jets supplied by
hand- worked pumps.

496. Rigged model of life-boat and carriage. (Scale 1 : 10.)
Lent by the Royal National Life-Boat Institution, 1865.

N. 1070.

This represents a fully equipped life-boat on its transporting carriage, as
designed by Mr. John Prowse in 1861 and adopted by the Royal National
Life-boat Institution.

The boat in general form resembles a whale boat, and is diagonally
built of two thicknesses of mahogany. She has five thwarts 2 6 ft. apart,
and pulls ten oars, double banked, in crutches formed on the thole pins.
Extra buoyancy is obtained by compartments under the deck filled with
watertight cases packed with cork, by detached air cases under the head
and stern sheets and along the sides under the thwarts, and by raised air
cases in the ends. This boat could hardly be capsized, but should such an
accident occur, the sheer of the gunwale, the raised end cases, and an iron
keel, would cause her to right herself. Large delivery valves enable the
boat to free herself of all water above the deck in 20 seconds, even with
47 persons on board.



147

The transporting carriage consists of a fore and a main body. The latter
is formed of a keelway, together with side or bilgeways resting on the main
axle, the boat's weight, however, being entirely on the rollers of the keelway.
On the withdrawal of a locking pin the fore and main bodies can be detached
from each other, so that when the boat is launched from the rear end the
keelway and main body form an inclined plane. To replace her on the
carriage, she can be hauled bow foremost up the fore end or longer incline
by disconnecting the fore carriage and letting the end of the keelway rest
on the ground. The bilgeways are needed at the rear end in order that the
boat may be launched in an upright position with her crew on board, but are
not required at the fore end of the carriage.

A life-boat provided with a carnage on which she is kept, ready for
transportation to the most favourable position for launching to a wreck, is
available for a much greater extent of coast than would otherwise be
possible, while a carriage is also of immense value in launching a boat from
a beach through a high surf.

497. Built model and drawing of life-boat "Lady Daly."
(Scale 1 : 16.) Lent by H.R.H. the Duke of Saxe-Coburg-
Gotha, KG., 1869. N. 1314.

This is equipped with masts, sails, oars, crutches, anchors, throwing
lines, etc., and is in a cradle on a permanent launching slip. It represents
a life-boat constructed at Adelaide, Australia, in 1867, from designs by
Mr. W. Taylor, Government shipwright at that port. She was fitted with
two standing lugs and a foresail.

The model was presented in 1868 by the Marine Board of South
Australia to H.R.H. the Duke of Saxe-Coburg-Gotha when in command
of H.M.S. " Galatea."
