In the case of the tug Quickstep, 9 Wall. 665, the owner of the canal boat Citizen filed a libel in rem against the tug, alleging that the tug attempted to tow too many loaded boats and in consequence of which one of the boats broke loose, and the tug while backing in an attempt to pick her up collided with and sank the Citizen.
The inquiry is: Who is to blame for this? Clearly not the Citizen, for it does not appear that her conduct in any way contributed to the accident. If the tug, in constructing the tow, used the lines furnished by the different boats, yet as each boat was independent of the other, no responsibility can attach to either for the breaking of the line, which she did not provide, and had nothing to do with making fast. In this case neither the bridle line nor the line that first parted were supplied by the Citizen, and she ought not to suffer for their insufficiency. It is well settled that canal-boats and barges in tow are considered as being under the control of the tug, and the latter is liable for this collision, unless she can show it was not occasioned by her fault.
It was the duty of the tug, as the captains of the canal-boats had no voice in making up the tow, to see that it was properly constructed, and that the lines were sufficient and securely fastened. This was an equal duty, whether she furnished the lines to the boats, or the boats to her. In the nature of the employment, her officers could tell better than the men on the boats what sort of a line was required to secure the boats together, and to keep them in their positions. If she failed in this duty she was guilty of a maritime fault. The parting of the line connecting the boat in the rear on the port side with the fleet, was the commencement of the difficulty that led to this accident. In the effort to recover this boat, the consequences followed which produced the collision. If it was good seamanship on the part of the captain of the tug to back in such an emergency, he was required, before undertaking it, at least to know that his bridle line would hold. And if the sea was in the condition the captain of the tug says it was, it was bad management to back at all. Whether this be so or not, he was bound, in executing a maneuver to recover the detached boat, to look to it that no other boat in the fleet suffered in consequence of it.
A tug is not required to subject herself to damage in order to protect her tow. An illustration of this is found in the case of the Mosher, 17 Fed. Cas. No. 9874, from which the following is quoted:
The schooner Nicaragua, owned by libellants, on the 6th of August having encountered a heavy wind and high sea, which continued during the day, came to anchor, and shortly after, the tug Mosher took her in tow. The schooner furnished the tow line. The first broke; a second bore the strain. The vessel in the act of being towed into the harbor was stranded and ultimately lost. Is the tug responsible for this loss?
It is charged that the accident happened through the negligence and want of care of the officers of the tug, and that, at any rate, the disaster would not have been so ruinous, if these officers had used proper efforts to relieve the Nicaragua. The first question is, what degree of diligence and skill was required of the tug? The rule is well settled that reasonable diligence and ordinary skill is the measure of the tug's duty. The tug did not engage to insure the safety of the tow, nor for the use of the highest nautical skill. I think Judge Drummond stated the rule fairly, that the tug is bound to know the ordinary and proper channel into the harbor and to exercise reasonable skill under the circumstances, in towing the vessel.

Like the district judge, I do not wish to relax the need of caution of tugs in towing vessels nor establish harsh rules to make them insurers of property.

In what respect did the Mosher show less diligence and skill than required? The schooner having taken the chances of entering the harbor in a storm, the tug is not to be held responsible, in the absence of proof of negligence, if the schooner touched some ridge of sand. It is urged that she went aground on the old sand-bar. Although satisfied that she was ultimately wrecked there, I am not satisfied she first struck there. The winds and waves drove her south, and the probability is that her first position was changed.
