Steam yachts having abnormally high speed are occasionally seen in a large yachting fleet. There are always a few men, who, from a love of seeing their names in print and their movements and those of their yacht recorded in the newspapers of the day, find that by tearing up the waters of our bays and harbours with yachts which show a speed of 25 miles an hour, their fondest hope is realised; for every eye follows them, and every reporter wastes his pencil in recording the performances of the speedy craft. It is their delight on regatta days to dart about amongst the fleet of yachts and craft of the lookers-on, and astonish everybody by some new flight of speed or some skilful evolution. I am happy to record, however, that the number of these flyers is small, and becoming less: such speeds are attained only by great danger to life and limb of those in charge of the machine, and an entire loss of comfort from the violent vibration of the vessel; for she must be built as light and carry as powerful machinery as possible, to give the results desired by these morbid lovers of notoriety, who are no more yachtsmen than is the man who takes a balloon trip so as to be seen by the crowd. It must be admitted that comfort and pleasure can be, and doubtless are, found on many steam yachts; for instance, a yacht of 125 ft. water-line, by 19 ft. beam, with a well-kept flush-deck, a comfortable deck-house forward, a large awning spread over all, the deck set out with Persian rugs, tables, and comfortable rattan chairs, and a number of congenial friends present, who are not tired of life and each other--I think no one will deny that pleasure in the highest degree could be realised with such surroundings. Our prevailing pleasant weather during the yachting season, and the uniformly sheltered character of our waters, have had their effect on the form and construction of steam yachts as well as those by sail. Nearly 95 per cent. of all steam yachts in America are built expressly for bay, harbour, and river work, and when it is necessary to make any extended trip, as for instance to the coast of Maine, they usually creep close along shore, moving cautiously from port to port. We can, however, boast of a few deep-sea craft, as fine and seaworthy as any pleasure vessels in the world, such as those owned by the late Jay Gould, Mr. W. W. Astor, the Vanderbilts, and few others. The general dimensions of many steam yachts are ruled by the probability of their taking the passage through the Erie Canal, the locks of which are 100 ft. long and 17 ft. wide, and admit a vessel drawing 6 ft. of water.
