Plaintiff has not argued that there is an unseaworthiness doctrine in Pennsylvania law which would be applied even though federal maritime law is not. Nor are we aware of any such doctrine. See Cooper v. Australian Coastal Shipping Comm'n, 338 F. Supp. 1056 (E.D.Pa. 1972), aff'd mem., 474 F.2d 1340 (3d Cir. 1973); McNeil v. A/S Havbor, 339 F. Supp. 1264 (E.D.Pa. 1972). We also believe, however, that even if the warranty of seaworthiness applies in this case, that the improper pierside method of operation by the stevedore did not render the ship unseaworthy.
This approach eliminates the need to consider the extent to which maritime law is applicable in a diversity action. See generally McNeil v. A/S Havbor, 339 F. Supp. 1264 (E.D.Pa. 1972). II
