The safety and comfort of one's ship's company, too, is a double source of anxiety when some or the whole are not seafaring by profession. For it must not be forgotten even in the finest weather that there is no such thing as 'playing at sailors' when at sea. The risk involved is not appreciably increased by manning the vessel with amateurs, if the officer in command will take certain precautions; and this view was endorsed by the insurance companies, who in no instance increased the premium on the 'Hornet.' The owner must insist on shipping a due proportion of old hands in each crew, and take care to train them as helmsmen and leadsmen. He should relieve the 'wheel' and 'look-out' as often as practicable. Above all, he should be careful to shorten sail in good time, and always at dusk, until he can depend upon his crew. Active and courageous as the amateur seaman invariably is, he has not the practice aloft of the professional, he cannot shorten sail so rapidly, nor does his knowledge of the lead of the ropes enable him to identify them so readily in the dark. The services of a good professional boatswain, with an enthusiastic love for his profession and a cheery sympathetic manner as an instructor, are absolutely essential for the proper working of a Corinthian ship. A minute and careful observation of the barometer, and constant verifying of position by reckoning and by observation, are the duties of the officer rather than the crew. Unless the yacht-owner be an enthusiastic navigator, delighting in his sextant and mathematical formulæ as well as a keen sailor-man, he had better not attempt this exacting if fascinating method of sailing his ship. On the other hand, the Corinthian crew is a cheery one, well mannered and enthusiastic, grateful for any instruction which is given them, and happy in an exceptional and delightful holiday. As a Corinthian crew is in general more numerous than one composed of professional sailors, when they have learnt their stations and become accustomed to the work, the vessel may be handled with that old-fashioned man-of-war smartness which is so attractive.
