A clause appearing in a contract of affreightment when disputes may be subject to US law. The clause obligates the owners of cargo to contribute to general average in cases of danger, damage or disaster resulting from faults or errors in navigation or in the management of a vessel or its machinery, provided that the owner shall have exercised due diligence to make the vessel in all respects seaworthy, and to have it properly manned, equipped and supplied. The clause avoids the consequences of a US court decision which held that a shipowner could not recover cargo’s proportion of general average arising out of a negligent navigation or error in management.
