ISSUE:
Can the Appellants be held partly liable for damage to the barge and for the lost cargo by not having an attendant aboard the barge when it broke free from the pier.
RULE:
There is no general rule to determine when the absence of an attendant will make the owner of the barge liable for injuries to other vessels if the barge breaks away from her moorings
If (Burden < Cost of Injury × Probability of occurrence), then the accused will not have met the standard of care required.
