But the evidence does not show with such certainty the precise place of the collision in reference to the turn of the Plymouth Bock to the eastward, as warrants me in holding that the attempt to pass in the narrow and tortuous channel at Hell Gate was immaterial. The large steamer Pilgrim was following up a little astern of the Plymouth Bock. Shortly before the collision she gave the Dentz a signal of one whistle, meaning that she would pass the Dentz on the latter’s starboard side, to which the Dentz also assented. This was an additional violation of the same rule of the supervising inspectors, that increased threefold the dangers of the passage. The Pilgrim had been in sight, and the Dentz may possibly have sup- posed she was bound to leave space for her; and if the Dentz intended to go iu mid-channel, so as to leave room for one steamer on each side of her, there was great liability to error of judgment in this at- tempt. The duties of these several steamers must, however. be considered in reference to the inspector’s rules, as much as to the st-ttutory rules. When the Dentz had agreed that the Plymouth Bock might pass upon her port hand, it became the duty of the Dentz to give ample space by going upon the starboard side of the channel, which was unob- structed, and by keeping on that side all the way around the bend to the right a little above Flood rock, under a port wheel, so as to give the Plymouth Bock, with her great length, room to swing without danger. Instead of doing so, the Dentz, even according to her own testimony, was no further to the right than mid-channel, and was kept heading directly towards the Hog’s Back on the northern shore. As she makes the place of collision one-third of the distance towards the Hog’s Back, it is not impossible that the collision arose after the Plymouth Bock commenced her swing to starboard. Considering the testimony of the libelant, who is mainly in the sit- uation of an impartial witness, it is probable that the collision was not as near to the Gridiron as the witnesses for the Plymouth Bock state. But in view of the narrow channel, the sharp turn of nearly · a right angle just beyond Flood rock, and the great length of such boats as the Plymouth Rock, Imust hold it a culpable fault in the _ Dentz-First, to have assented to any departure from the inspectors’ rule; and, second, having done so, not to have kept upon the star- board side of the channel-way, directly _around Hallett’s point, so as to give undoubted room for the Plymouth Rock to make her necessary turn. ‘ . 2. The Plymouth Rock is also in fault, both for deliberately vio- lating the inspectors’ rule, and also for not stopping and backing in
