This is a case of collision. It occurred on the East River, in the afternoon of the 5th of August, 1863, between the yacht Ariel and the schooner Grace Girdler. Both vessels were beating down the river to the bay. The yacht had made her long tack, and had gone about near the New York shore, and was standing upon her short tack across the river. The schooner had done the same things, and was standing in the same direction. In going about she had passed to the windward of the yacht, and held that position in her short tack. The yacht was to the leeward, and a very little way in advance. As she was beginning to make headway, the approach of a steam ferry-boat coming up the river compelled her suddenly to luff three or four points in order to get out of the way. This threw her unexpectedly in the way of the schooner, and was the proximate cause of the collision. The vessels came together, and the yacht was sunk and lost. The locality of the collision was opposite to the foot of Stanton or Grand Street, in the city of New York, and about one-third of the way across the river.

So far both sides agree as to the facts, but no further. Here begins the stress of the case, and the antagonisms in the testimony of the parties gather around it.

The Grace Girdler (74 U.S. 196)/Opinion of the Court

The libellants allege that the schooner was wholly in fault. They say that she ought not to have been so near the yacht; that she ought to have seen the danger to the yacht from the approach of the ferry-boat, and seeing it, ought immediately to have luffed, to get more to the windward; and that if she had done so, the accident would not have occurred. They insist that the schooner, being so nearly in the track of the yacht, and in such close proximity, it was her duty to exercise the greatest vigilance, and to omit no precaution against danger.

The Grace Girdler (74 U.S. 196)/Opinion of the Court

The respondents insist that there was no fault on the part of the schooner; that when the yacht suddenly came into her path to avoid the ferry-boat, the schooner, if not in stays, had so little headway on that she was powerless to change her course, or to do anything else to prevent the two vessels from coming in contact. In behalf of the schooner there is testimony to the effect that the yacht, having escaped the ferry-boat by luffing, should have luffed still more to avoid the schooner, and that if she had performed this simple and obvious duty, the collision could not have occurred.

The Grace Girdler (74 U.S. 196)/Opinion of the Court

The schooner was thoroughly manned. The captain was an experienced seaman. A regular Hurlgate pilot was at the helm.

A pleasure-party was on board the yacht. Lockwood, the captain, was the superintendent of an oil warehouse. He had served as a seaman during a voyage to California in 1849. He had no other nautical experience. Slavin was the sailing-master. He was twenty-two years of age, and had some experience as a sailor. He 'had been, off and on, five or six years, sailing-master of those small vessels about New York,' and 'had been on the Ariel six or seven weeks at that time.' Before he went upon the yacht he had been at work for Lockwood in an oil factory. Lockwood, in his deposition, says, 'All on board were gents but Slavin and an extra hand.' The testimony of the extra hand has not been taken, and it is not shown who he was, what were his qualifications, or in what capacity he served. It does not appear that any one was charged with the duty of a look-out. Lockwood, the captain, was at the helm. He says:
