CHAPTER XI. BOAT-BUILDING AND DIMENSIONS.

Previous

The ‘trim built wherry’ of song has been improved off the face of the Thames. Originally it was purely a passenger craft: it contained space for two or more sitters in the stern, and was fitted for two pair of sculls or a pair of oars at option. Larger wherries were also built, ‘randan’ rig (for a pair of oars with a sculler amidships, or three pairs of sculls at option). Such boats were the passenger craft of the silent highway before steamers destroyed the watermen’s trade. When match racing came into vogue, wherries began to be constructed for purely racing purposes; they had but one seat, for the sculler, and were carried as fine as they could be, at either end, with regard to the surf which they often had to encounter. Their beam on the waterline was reduced to a minimum; but at the same time it was necessary, for mechanical purposes, that the gunwale, at the points where the rowlocks were placed, should be of sufficient width to enable the sculler to obtain the necessary leverage and elevation of his sculls. The gunwale was accordingly flared out wide at these points, above the waterline. This flared gunwale had nothing to do with the flotation of the boat; it was in effect nothing more than a wooden outrigger, and it was this which eventually suggested to the brain of old Harry Clasper the idea of constructing an iron outrigger, thereby enabling the beam to be reduced, and at the same time the sculling leverage to be preserved without the encumbrance of the top hamper of these flared gunwales. Such was the old wager wherry, and its later development of the wager outrigger.

We have said that the wherry is obsolete. Modern watermen use, for passenger purposes, a craft called a ‘skiff.’ She is an improvement on the ‘gig,’ a vessel which came into vogue on the Thames for amateur pleasure purposes about the year 1830. The ‘gig’ was originally adopted from naval ideas. She had a flush gunwale, and the rowlocks were placed on the top of it. So soon as the outrigger came in, oarsmen realised the advantage to be gained by applying it to the gig, in a modified form. Half-outrigged gigs became common; they had a reduced beam, and commanded more speed; they were used for cruising purposes as well as for racing. Many regattas offered prizes for pair oars with coxswains in outrigged gigs. Theoretically a gig was supposed to be ‘clinker’ built, i.e. each of her timbers were so attached to each other that the lower edge of each upper timber overlapped the upper edge of the timber below it, the timbers being ‘clincked,’ hence the name. ‘Carvel’ (or caravel) build is that in which the timbers lie flush to each other, presenting a smooth surface. This offers less resistance, and before long builders constructed so-called ‘gigs’ for racing purposes, which were carvel built. From this it was but a step to build racing gigs with but two or even one ‘streak’ only, i.e. the side of the hull, instead of being constructed of several planks fastened together, was made of one, or at most two planks. The ends of the vessel were open—uncanvassed, and in this respect only was there anything in common with a ‘gig’ proper. This system of stealing advantages by tricks of build caused gig races to be fruitful sources of squabbles, until regatta committees recognised the importance of laying down conditions as to build when advertising their races.

To return to gigs proper. This craft did not find the same favour fifty years ago with the professional classes that it did with amateurs. The wherry was still adhered to for traffic; but meantime Thames fishermen, especially those who plied flounder fishery on the upper tideway, used what is called a skiff; a shorter boat, with as much beam as the largest wherry, a bluff bow, and flared rowlocks. She was strongly built, adapted to carry heavy burdens, and, by reason of being shorter, was easier to turn, and handier for short cruises. A similar class of boat, but often rougher and more provincial in construction, was to be found in use at some of the up-river ferries. The wherry, when once under way, had more speed than the skiff, but when long row-boat voyages ceased in consequence of the introduction of steamers, the advantage of the skiff over the wherry was recognised by watermen. Their jobs came down to ferrying, to taking passengers on board vessels lying in the stream, and such like work; and for these services speed was not so important as handiness in turning.

During the last fifteen years the skiff build has found more favour for pleasure purposes than the gig. The outrigged gig is liable to entanglement of rowlock in locks, and where craft are crowded, as at regattas. (It would be a salutary matter if the Thames Conservancy would peremptorily forbid the presence of any such craft at Henley Regatta.) Inrigged craft glide off each other when gunwales collide, whereas outriggers foul rowlocks of other boats, and cause delay and even accidents. An outrigged gig has two alternative disadvantages, compared to the skiff build; if she is as narrow at the waterline as the skiff, her flush gunwale reduces the leverage for oar or scull. If, on the other hand, she is built to afford full leverage, this entails more beam on the waterline than in a skiff, the rowlocks of which are raised and flared above the gunwale. Hence it is that the skiff build is gradually superseding the once universally popular gig.

A dingey is a short craft, originally designed as a sort of tender to a yacht, but adopted for pleasure purposes on the Thames for nearly half a century. It is sometimes built with a flush gunwale like a gig, but more commonly with flared rowlocks like a skiff, thereby affording the required leverage for swells, while at the same time reducing the beam on the waterline.

Besides the above mentioned craft, which are designed to carry at least two oarsmen (or scullers) and a coxswain, modern boat-builders construct what are called sculling dingies and gigs, which are fitted with only one pair of rowlocks, and are intended mainly for occupation by a single sculler, though they will at a pinch carry sitters both in the stern sheets and in the bows. They also build sailing gigs and dingies, which are usually fitted with a ‘centreboard,’ and are of greater beam than those specially designed for rowing or sculling; though they can be also propelled by oars or sculls when required, they are less handy for the latter purposes, in consequence of their construction for the double duties of both sailing and oarsmanship. The following are dimensions commonly adopted by builders, such as Messrs. Salter of Oxford, for various classes of gigs, dingies, and pleasure skiffs:—

Length. Beam.
Gig, pair-oared, inrigged 22 ft. 3 ft. 9 in.
ditto randan 25 ft. 3 ft. 9 in.
Skiffs, pair-oared 25 ft. 4 ft. 0 in.
ditto 23 ft. 4 ft. 6 in.
ditto 20 ft. 5 ft. 0 in.

The variations in beam being in such vessels designed conversely as regards the lengths, in order to obtain approximate equivalent of displacement—

Length. Beam.
Skiffs, randan 26 ft. to 27 ft. 4 ft. 0 in.
ditto 25 ft. 4 ft. 6 in. to 5 ft

Where the beam ranges as high as 5 feet the vessel will carry about four sitters in the stern. The narrower craft carry about two, sitting abreast in the stern.

Dingies (inrigged) range from about 12 feet in length with 4 feet beam to 16 feet in length with about 3 ft. 6 in. beam.

Some dingies are built as short as 9 feet, but they command but little speed, and are useful only as tenders to larger vessels for the purpose of going ashore, &c. Their shortness makes them handy to turn, and compensates in short journeys for their want of speed.

The prices of the various builds enumerated above depend much upon the materials used, whether oak, mahogany, cedar, or pine; and also upon length of keel, and upon fittings, such as oars, sculls, cushions, stern-rails, &c., masts and sails. Figures vary from about 40l. for a best quality randan skiff, all found, to as low as 20l. for a gig, and 12l. for a dingey, turned out new from the builder’s yard.

It is customary to fit all rowing boats such as above described with a hole in the bow seat, and also in the flooring below, in order to carry a lug or sprit sail when required; but the shallow draught of such vessels as are not fitted with centreboards causes them to make a good deal of leeway and so disables them from sailing near the wind.

Racing boats are generally built of cedar, sometimes of white pine. The history of the introduction of the various improvements of outriggers, keelless boats, and sliding seats, has been given in other chapters. We propose here simply to give a few samples of dimensions of racing boats.

Various builders have various lines, and no exact fixed scale can be laid down as correct more than another.

These boats are selected because each in its turn won some reputation, and also because they exemplify the builds of different constructors.

No. 1 was always highly esteemed by those who rowed in her.

No. 2 carried Eton at Henley Regatta from 1863 to 1870 or 1871.

No 3 was eulogised by Mr. T. Egan in ‘Bell’s Life,’ on the occasion of her dÉbut in the above-mentioned school match v. Eton. She retained a high reputation for several seasons, was once specially borrowed by Corpus (Oxon) during the summer eights, and was said by that crew to be a vast improvement on their own ship.

No 4 carried Oxford from 1878 to 1882 inclusive, losing only the match in 1879, in which year the crew and not the boat were to blame.

No. 5, after one or two trials, was in 1883 found to be faster than No. 4 (which was then getting old!), and in her the Oxonians won a rather unexpected victory; odds of 3 to 1 being laid against them.

In addition to these builds, the dimensions recorded by the well-known authority ‘Argonaut,’ in his standard work on ‘Boat Racing,’ are here given. That writer does not commit himself to saying that they are the best, but simply states that they are the ‘average dimensions’ of modern racing boats. Unfortunately, the writer cannot trace the dimensions of the celebrated ‘Chester’ boat, Mat Taylor’s first keelless chef-d’oeuvre, but he recollects that her length was only 54 feet; and her stretchers were built into her and were fixed.

The cost of a racing eight, with all fittings, is about 55l. Some builders will build at as low a price as 50l., especially for a crack crew, or for an important race, because the notoriety of the vessel, if successful, naturally acts as an advertisement. A four-oar costs 35l. to 40l.; a pair-oar 20l. to 25l.; and a sculling boat 12l. We have known some builders ask 15l. for a sculling boat. On the whole, racing boats are from eight to ten per cent. cheaper nowadays than they were a quarter of a century ago. Although the introduction of sliding seats necessarily adds to the expense of making them, competition seems to have brought down the prices somewhat.

[11] Measured from front edge of slide to plane of thowl.

The writer thinks, and believes that ‘Argonaut’ would agree with him, that these recorded average dimensions could be improved upon in divers respects, e.g. as to oars, for sliding seats the length ‘inboard’ should not be less than 3 ft. 71/2 in. to 3 ft. 8 in.; otherwise, when the oarsman swings back there is not sufficient length of handle to enable his outside hand to finish square to his chest, and with the elbow well past the side. The sliding-seat oar requires to be at least 10 inches longer inboard than the fixed-seat oar, for the above reason; and in order to counterpoise this extra leverage, it is customary to use blades an inch wider for slides than for fixed seats, viz. 6 inches wide at the greatest breadth, instead of 5 inches as of old.

Again, as to distance of the plane of the thowl perpendicularly from that of the front of the slide when full forward. This should not be less than 61/2 inches, in the writer’s opinion, even with a 16-inch slide. If the oarsman slides nearer than the above to his work, he does not gain; for much of his force is thus expended in jamming the oar back against the rowlock, rather than in propelling the boat. He ‘feels’ extra resistance, and may accordingly delude himself that he is doing more work, if the slides close up; but in reality he is wasting his powers.

In modern racing boats, the men slide too close to their work; and if any builder will have the courage to set his men further aft than is the custom (say about 61/2 to 7 inches), he will find his ship travel all the faster.

As to shapes of hull: the earliest Mat Taylor boats have never been surpassed, in the writer’s opinion, and were much faster than the modern builds. The peculiarity of Mat Taylor’s build was that he put his greatest beam well forward, about No. 3’s middle or seat. Such boats held more ‘way’ than more modern craft, which are fullest amidships.

Builders of the present day construct as if the only problem which they had to solve was to force a hole through the water in front of the boat. This is not all that is necessary in order to get a boat to travel well. A racing boat leaves a vacuum behind her, and until that is filled she is sucked back into that vacuum.A boat built like the half of a split porcupine’s quill could enter the water with the least resistance, but would leave it with the greatest; in fact, she would not travel at all, because her bluff stern would create a sudden vacuum behind her, which would retard her progress. This is a reductio ad absurdum, but it shows the effect of having the greatest beam too far aft. The problem to be solved in designing the lines of a boat is so to arrange her entry into the water, that what she displaces in front may with greatest ease flow aft to fill the vacuum aft which she leaves as she progresses. Otherwise she pushes a heavy wave in front of her, and drags another behind her. If anyone will watch the bank as a racing eight passes, noting the level of the water at a rathole, he will see the level of the stream first rise as the boat comes nearly abreast of his point of observation. Then, as she passes, the water will sink, and after she has passed it will rise again higher than before she neared the spot.

The first rise is caused by the boat pushing a wave in front of her: the following depression is caused by the vacuum which she is leaving behind her, and the final rise by the wave which runs behind her to fill her vacuum. Obviously, the less water the vessel moves the easier she travels. If by any designing the wave pushed in front could be induced to run more or less back to the stern, then the second (following) wave would be more or less reduced in bulk, and the labour would be proportionately lighter.

The finer the lines taper aft, the easier the front wave displaced finds its way to the vacuum aft. Per contra, the more bluff the midship and stern sections, the greater the difficulty in filling the vacuum aft.

Builders hamper themselves by adhering to a red-tape idea that all oarsmen in a boat should be seated at equal distances from each other. So long as designers adhere to this, they require a good deal of beam aft, if Nos. 6, 7 and stroke are of anything like average size. Of course, there must be a minimum of space for each man to reach out in; but there is no reason why in some of the seats the space should not exceed this minimum, e.g. to set the first four men at the minimum, and then to place No. 5 and extra inch past No. 4 and so on, with perhaps stroke and 7 11/2 inches further apart than the forward men, would enable the builder to attain a greater longitudinal displacement at the sternmost part of the boat than he would otherwise require to carry his men. In lieu of this gain, he can then reduce his beam and depth aft, and so make his lines taper more to the stern.

Mat Taylor built on this principle. Detractors used to laugh sometimes to see him chalk off his seats, and say, ‘A rowlock here—a seat there.’ The fact was, Mat Taylor placed his men, man for man, over the section of vessel built to carry them, allowing the minimum distance for reach in all cases, but by no means tying himself down to that distance where in his opinion the boat required elongating aft. They said he built by rule of thumb; so, perhaps, he did, but his builds have never been surpassed. Modern eights travel faster than of old, thanks to sliding seats and good oarsmanship, but if some of the old lost lines could be now reproduced, the speedy crews of modern days would be speedier still.

We offer one more illustration to show the effect of having too sudden a termination to a boat aft of her greatest beam, or of a certain amount of beam. Let anyone construct two models of racing boat hulls; probably he will not succeed in making two of equal speed, but such as they are he can handicap the speedier in his experiment. Let him place the two models to race, each towed by a line carried over a pulley, with a weight at the end of the line. The weights which tow the two models can be adjusted till the two run dead heats.

Then cut off the stern of one of the models, and bulkhead her, say about coxswain’s seat, and let them race once more with the forces which previously produced a dead heat. The model with a docked stern will have become the smaller vessel, and will now weigh less. Nevertheless, she will become decidedly slower than she was before, and will be beaten by her late duplicate.In order to do justice to this experiment, the weights should tow at a pace equivalent to about four miles or more an hour. It will then be seen that this docked model leaves a whirlpool behind her stern, which is retarding her. This experiment of course exaggerates the principle of full afterlines, and their evil, but it may none the less serve to illustrate the importance of a finer run aft from a point further forward than amidships. En passant, the boat built by Salter of Oxford for the O.U.B.C. in 1865 may be mentioned; her dimensions are not to be traced, but she was specially designed to carry the heaviest man (E. F. Henley) at bow. She was certainly never surpassed by any other boat which Salter built. She won in 1865. In 1866 a heavier crew were in training, and the 1865 boat was supposed to be too small. She was not tried at all at Oxford with the crew. A new boat was built, this time to carry E. F. Henley at 5. When the crew reached Putney the writer felt dissatisfied with the movement of the new boat, and persuaded the crew to try the old one, even though she would be rather too small for them. They sent for her, and launched for a trial paddle the Monday before the race; so soon as they had rowed a dozen strokes in her they stopped, and declared she was the only light boat they had felt that season. They rowed the race in her, and won, and never took the trouble to set foot again in the new and rejected boat.

This victorious boat was then bought by the Oxford Etonians. They won the Grand Challenge of 1866 and 1867 in her, took her to Paris, and there won the eight-oared race at the International Regatta. She was sold and left behind in Paris. The writer suspects that her undeniable speed was mainly owing to the fact that Salter designed some extra displacement at No. 3, in order to carry E. F. Henley at that seat.
