'LETHE'
163 tons, showing lead keel and construction. Designed by G. L. Watson. Built by Fay & Co., 1889.
A considerable factor in modifying form was the gradual abolition of shifting ballast; this, though not yet actually illegal, was being more and more looked upon with disfavour, and as the use of outside lead increased, it was found that depth was a more than sufficient substitute for weather ballast, especially as beam was being squeezed down by the tonnage rule, and a long lever in this direction rendered impossible.
Timber was still the favourite material for building ('Mosquito,' 'Torpid,' and one or two others being the sole exceptions to this rule); but about 1860 a new system of construction was tried in which an iron framework was combined with a wooden skin or planking. This system came rapidly into vogue on the Clyde, and was adopted by several firms there in the building of those beautiful creations, the China clipper ships. The annual race home with the season's teas was the subject of discussion in the great Clyde shipyards, and I can well remember the highest ambition of every spirited lad in the drawing office was to live to design a China clipper. The Suez Canal closed for ever this avenue to fame.
Among the most successful builders of these ships were Messrs. Robert Steele & Co., of Greenock, who had, so early as 1807, built yachts for the Excise and for various Scotch owners. Mr. William Steele of that firm being an able designer of yachts as well as of ships, it was natural that this method of construction should be adopted by him in the building of 'Nyanza,' 'Oimara,' 'Garrion,' and the majestic 'Selene,' to-day one of the handsomest schooners afloat; while many of that firm's large steam yachts, notably the 'Wanderer,' 850 tons, the finest auxiliary yacht of her day, were built on this plan.
Dan Hatcher of Southampton carried out this system in building several vessels, commencing with a schooner, the 'Bella Donna,' of 119 tons, in 1867; 'Seabird,' 126 tons, 1868; 'Lizzie,' of 20 tons, 1868; then, in one of his finest craft, 'Muriel,' which he built for Mr. Bridson in 1869; and in the famous 'Norman' he also adopted this construction. But, owing to the steel frame being considerably more expensive than timber, the composite build has never become popular until within the last few years, when the naturally weak shape of the modern yacht, the fact of all the lead being outside, and her enormous stability, have so increased the racking strains on the structure, that a merely wooden frame cannot be got to hold together without making the weight of the hull altogether prohibitive; and the composite racing yacht, for everything except very small vessels, seems likely to push all the others from the field. As illustrating this method of construction, a midship section is given of 'Lethe,' 163-ton yawl, and one of the finest of our cruising yachts. The photograph shows the lead keel, the heaviest ever cast, and also the method of securing the same to the bottom of the ship.
Since 'Mosquito' astonished the yachting world in 1848, until to-day when 'Navahoe' and other American racing yachts have been constructed of metal, iron and steel yachts have been more or less successful; but the difficulty of keeping a smooth and perfectly clean bottom is a considerable source of expense and worry, although the immense strength of the steel shell, and in a large yacht its lightness, will always be a set-off to the trouble of the uncoppered bottom.
'Lethe,' 163 tons. Built for S. C. Watson, Esq.—Midship section.
In a lecture on 'Progress in Yachting and Yacht-building,' which I delivered early in 1881, in a fanciful specification of the yacht for the season 2000, I required that the plating below water should be of manganese bronze. Curiously enough, a few years later saw an attempt to combine the strength of steel and the smoothness, anti-fouling, and non-corrosive properties of copper, in the building of a torpedo-boat of this material; while this year the chosen defender of the America Cup has been plated with a similar bronze on a steel frame, the builders claiming, and not without reason, that the additional smoothness of bottom gives her an advantage of five to seven minutes on a forty-mile course. But such a practice seems hardly likely to become general for ordinary racing yachts built for men with a normal depth of pocket, and whilst, as in the old Mississippi steamboat days, it sometimes paid to burn hams, most of us have to try and get along with good coal.
