I. History of the Case
The Petition of S. C. Loveland Co., Inc., in exoneration from, or limitation of, liability as late owner and operator of the barge Fell Loveland, was filed in this court on April 15, 1955. Subsequently, answers and claims were filed by three parties, who withdrew their claims prior to November 1958,1 at which time the petitioner asked the trial judge to proceed with decision in the case as to the remaining claimants because of inability to reach a settlement with them. In November and December 1958, Requests for Findings of Fact and Conclusions of Law were filed on behalf of the petitioner and the following claimants, who are the only three parties continuing as parties to this proceeding:
A. Florence Pipe Foundry and Machine Co. (hereinafter called “Florence”), the owner of the pig iron loaded aboard the barge Fell Loveland at the time she sank (see Answer of Florence filed 6/15/55 as Document No. 5 in Clerk’s file and Claim of Florence filed the same day as Document No. 6 in Clerk’s file).
B. Quaker City Navigation Co. (hereinafter called “Quaker”), claiming that it was unable to discharge its car*788goes of coke at the pier due to the obstruction of the sunken barge (see Answer of Quaker filed 6/17/55 as Document No. 12 in Clerk’s file and Claim of Quaker filed the same day as Document No. 11 in Clerk’s file).2
The trial of the case was held in February 1958. At the beginning of the trial, it was agreed that the issue of the amount of damages would be “reserved and passed on to a Commissioner” (N. T. 5 & 6). After the testimony was transcribed, counsel for Chester and counsel for petitioner asked the trial judge for more time to file their Requests for Findings of Fact and Conclusions of Law since “some headway was being made toward settlement of the issues.” 3 It proved impossible for petitioner to reach a settlement with Florence and Quaker and the above-mentioned Requests, together with supporting briefs, were filed in the last two months of 1958. Oral argument was heard on December 29, 1958.
The restraining order filed April 14, 1955, as amended May 14, 1956, will be further amended in accordance with the terms of Admiralty Rule 51 to make clear that it does not bar the institution of S. C. Loveland Co., Inc., etc., v. Florence Pipe Foundry & Machine Co., No. 59 of 1958 in Admiralty, as suggested at pages 8 and 9 of the brief filed by petitioner in that action on December 24, 1958.
II. ^Findings of Fact
1. All the requested Findings of Fact of petitioner, with the following four modifications, are adopted as Findings of Fact of the trial judge:
(a) There is added at the end of paragraph 3: “(This sentence is amplified and qualified by Finding of Fact 5 of the trial judge.)”
(b) Sub-paragraph 5(e) is reworded as follows: “All claims for loss and/or damage and/or expense against petitioner were waived by Florence ‘except for General Average, Sue and Labor and Collision Liability’ (see paragraph 10).” (See Exhibit L-3.)
(c) Paragraph 7 is modified by inserting at the beginning of the sentence “On the night of March 11, 1955” and by deleting the first word, “and,” in the second line.
(d) Paragraph 8 is modified by adding at its end the words “for carriage of 1000 tons of pig iron from Chester, Pa., to Florence, New Jersey.”
2. All the requested Findings of Fact of Florence Pipe Foundry and Machine Co. (hereinafter called “Florence”), except for paragraphs 5, 6, and 8, and with the following added at the end of paragraph 3, are adopted as Findings of Fact of the trial judge: “(This sentence is amplified and qualified by Finding of Fact 5 of the trial judge.)”
3. Subsequent to World War II, the barge Fell Loveland was converted4 for use solely on the inland waterways, since it became uneconomical to operate barges of her size in the coastwise trade.
4. The Fell Loveland carried the following loads in excess of 1000 tons between Chester, Pa., and Florence, N. J., *789prior to March 10, 1955, and .petitioner’s accountant had records showing that it was paid freight on the basis of these loads (Exhibits L-37 and L-32):
Weight In Date of Shipment Gross Tons (L-37) Date Bill Sent To Petitioner by Florence (L-32)
1012-1015 November 30, 1954 December 13, 1954
1016- 1020 December 29, 1954 January 7, 1955
1017- 1022 January 6, 1955 January 14, 1955
1022-1024 January 13, 1955 January 21, 1955
1079-1082 February 14, 1955 February 21, 1955
1066-1071 February 19, 1955 February 28, 1955
1061-1069 February 25, 1955 March 7, 1955
The president of petitioner did not know that the barge had carried in excess of 1000 tons on any of these loads prior to the sinking of the Fell Loveland (N.T. 41).
5. Barge Captain James’ duties included properly maintaining the barge (N.T. 34), checking the barge for water (N.T. 190), taking care that the barge was loaded in such a way that it would not be damaged or unnecessarily strained (N.T. 66, 189, and Answer to Interrogatory 18 in C.P. 3, Sept. Term 1955, No. 5003), but it was not his duty to determine the size of the load the barge was to carry (N.T. 192). Once, in February 1955, petitioner’s marine superintendent cautioned James about not putting too much weight in the barge (N.T. 195, 199, 267).5
6. James had the opportunity to call the marine superintendent or president of petitioner for instructions concerning the removal of the alleged extra carload of pig iron on the barge on the evening of March 11, 1958.
7. It was not possible to use the pier at which the Fell Loveland had been moored from March 12, 1955, when it sank, until the remains of the sunken barge were removed in June 1955.
8. Petitioner only decided to abandon the barge at the pier when they learned that the cost of salvaging it would be in excess of $25,000 and Chester would not “split * * * the expense with us of raising the barge” (N.T. 27-28).
9. There is no evidence that petitioner believed, or knew that Quaker was doing business regularly at the above-mentioned pier or that it had any contract with Chester or any other person involving the use of this pier.
III. Discussion
This is a petition of a barge owner in exoneration from, or limitation of, liability. Since the facts are set forth in the foregoing Findings, it is unnecessary to review here the circumstances surrounding the sinking of the barge Fell Loveland during the early morning of March 12, 1955, while tied to a pier in the Delaware River at Chester, Pa.6 There are attached to these History, Findings, Discussion and Conclusions *790the briefs of petitioner and of claimant Florence because of their helpful references to the testimony. Particular reference is made to the analysis of the testimony concerning repairs and maintenance and of certain expert witnesses at pages 11 to 17 of the petitioner’s brief with which the trial judge agrees.7
A. Petitioner is not entitled to exoneration because of the negligence of the barge captain.
The barge captain (James) was negligent in not requiring the employees of Chester to remove the excess pig iron from the barge on the night of March 11, 1955, as well as in not notifying one of the superior officials of his company of the situation to secure their advice.8 The trial judge finds that this overloading was the cause of the barge’s sinking.9 Even though James was only told that there was one extra carload of pig iron on the barge, whereas there were at least two such extra carloads on the barge,10 he had been cautioned by the marine superintendent the previous month that he should not put too much weight in the barge and, in the exercise of due care, he should have realized that the 1144-ton load was substantially (14%) heavier than the approved maximum load of approximately 1000 tons.11
B. Petitioner is entitled to limitation under 46 U.S.C.A. § 183(a).
The facts that petitioner’s marine superintendent had given petitioner a general warning about overloading the barge after the first February trip and that subsequently petitioner’s accounting department received a statement dated February 28, 1955, showing that about 1070 tons had been loaded on the barge for the second February 1955 trip,12 do not amount to knowledge that *7911144 tons were likely to be loaded on the barge. If petitioner is to be charged with the knowledge of the loads as shown on the statements in its accounting department, it knew that the Fell Loveland had successfully carried seven loads ranging from 1012 tons to 1082 tons each between November 30, 1955, and March 7, 1956, but there was no suggestion that an 1145-ton load would be carried.
After considering (1) the testimony of petitioner’s marine superintendent that a 12-inch freeboard was enough for this “run up the river,” in view of the 10-inch hatch combing on the barge (N. T. 196), and (2) the successful carriage of the seven previous loads varying from 1015 to 1082 tons on this “run,” 13 the trial judge does not believe the reasoning in In re Petition of American Dredging Co., D.C.E.D.Pa.1956, 141 F.Supp. 582, 586, affirmed, 3 Cir., 1956, 235 F.2d 618, reversed on other grounds Kernan v. American Dredging Co., 1958, 355 U.S. 426, 78 S.Ct. 394, 2 L.Ed.2d 382, relied on by Florence, is applicable to the facts of this case. On the present record, the trial judge (recognizing that petitioner has the burden of persuasion on its right to limitation, as well as the burden to come forward with evidence to explain the sinking) does not believe that a finding of continued dangerous overloading of the barge after the cautionary instruction, but prior to March 10, 1955, is justified. There is every reason to believe that the barge could carry 1070 tons safely, but that the extra 75 tons were enough to dangerously overload it.
The trial judge has found no evidence in the record supporting Florence’s claim (page 5 of its brief) that James “made no effort to pump the bilges.” James is entitled to the presumption of due care applicable to a decedent.
The trial judge concludes that the loss and damages to the cargo were “without the privity or knowledge of” petitioner, which is entitled to limitation of liability under the terms of 46 U.S.C.A. §§ 183 (a) and 188.
C. Florence is entitled to such damages as may be found to fall under the terms “General Average” and “Sue and Labor.”
In this suit, it is not necessary to decide what obligations Florence may have to petitioner arising out of Clauses 1 and 2 of the Contract.14 It is clear that petitioner is responsible for the negligence of James, and Florence expressly reserved in the contract claims “for General Average, Sue and Labor.”15
The trial judge finds that Florence was not contributorily negligent in receiving the two cargoes of over 1060 tons shipped on February 19 and February 25, 1955, without further complaint for the reasons stated above in the first paragraph under B. Any negligence of Ches*792ter in overloading the barge and telling James that one, rather than two, extra cars had been loaded cannot be imputed to Florence, which had advised Chester that the loads should not exceed approximately 1000 tons (N.T. 265-6).
D. The claim of Quaker must be dismissed on this record.
Quaker’s claim alleges a deprivation of “ * * * its contractual rights with Chester Blast Furnace, Inc. whereby claimant would have been netting each month $7,500 for the discharge of coke there (at the pier where the barge sank on March 12) * * *."16 No evidence was offered to show that Quaker had any contract for future deliveries but, even if this is assumed, there was no allegation or proof that petitioner knew of any such contract. Furthermore, there is no evidence that the sinking of the barge was intentional (see Findings of Fact 8 and 9). Under these circumstances, Quaker’s claim must be dismissed.
The law has consistently recognized that negligence (as opposed to intentional conduct) which results in interference with the contract right of another is no basis for a cause of action for damages where the negligent party has no belief or knowledge of the existence of such contract right. See Restatement of Torts, § 766, comment d,17 and § 870, comment e; Robins Dry Dock & Repair Co. v. Flint, 1927, 275 U.S. 303, 308-309, 48 S.Ct. 134, 72 L.Ed. 290; Borcich v. Ancich, 9 Cir., 1951, 191 F.2d 392, 397-398; cf. Sweeney v. Smith, C.C.E.D.Pa.1909, 167 F. 385, affirmed, 3 Cir., 1909, 171 F. 645; certiorari denied, 1909, 215 U.S. 600, 30 S.Ct. 400, 54 L.Ed. 343.
In Donovan Construction Co. v. General Electric Co., D.C.Minn.1955, 133 F.Supp. 870, 874, the court said:
“Mere negligence in interfering with another’s contract rights will not sustain the cause of action for damages * * *. There are a multitude of cases which sustain the principle that, as an indispensable condition precedent to liability for interference with the performance of one’s contract, there not only must be knowledge of the contract, but there must be an intentional interference therewith.”
