INTRODUCTION

Alyeska Pipeline Service Company (“Alyeska”) appeals the district court’s *383 grant of relief on The Vessel BAY RIDGE (“BAY RIDGE”) motion to vacate arrest and to dismiss complaint. ** The BAY RIDGE cross-appeals from the district court’s conclusion that Alyeska’s claim against the vessel gave rise to a valid maritime lien. The district court concluded the maritime lien was valid but the arrest of the BAY RIDGE pursuant to Fed.R.Civ.P. C (Supplemental Rules for Admiralty and Maritime Claims) (“Rule C”), violated the due process clause of the fifth amendment of the United States Constitution. The arrest was vacated, security held in place of the vessel was exonerated, and the case was dismissed.

FACTS

On May 19, 1980 Alyeska brought this action to recover costs it incurred cleaning up an oil spill near its tanker loading terminal in Valdez, Alaska. The action was brought in rem against the vessel BAY RIDGE. No in personam claims or actions were instituted.

Pursuant to Rule C, the vessel was arrested by the U.S. Marshal the day the complaint was filed. In accordance with Fed.R. Civ.P. E(8) (Supplemental Rules for Admiralty and Maritime Claims), the owners of the vessel filed a restricted appearance for the purpose of defending Alyeska’s claim against the vessel.

The vessel was released upon the issuance of a letter of undertaking. Shortly thereafter the letter of undertaking was replaced with another type of security, a stipulation for value in the amount of $450,000.

The vessel owners then moved to vacate the arrest and dismiss the complaint against the BAY RIDGE on the grounds that (1) Alyeska had no valid maritime lien, and (2) Rule C, the authority by which the vessel was arrested, violated claimants’ fifth amendment due process rights. On March 16, 1981 the district court issued an opinion which concluded that an enforceable lien existed but that Rule C violated the fifth amendment. Alyeska Pipeline Service Co. v. The Vessel BAY RIDGE, 509 F.Supp. 1115 (D.Alaska 1981). The court vacated the arrest of the vessel and dismissed the case. Id.

On March 18, 1981, pursuant to Fed.R. Civ.P. E(8) (Supplemental Rules for Admiralty and Maritime Claims), the vessel owners moved for an order exonerating and releasing the stipulation for value. Alyeska did not move to stay the exoneration or release of the stipulation for value and did not file a supersedeas bond. On March 23, 1981 the court exonerated and released to claimants the stipulation for value. Alyeska’s subsequent motions, including a motion to vacate the order of exoneration and to allow an in rem arrest of the exonerated stipulation for value were denied. Alyeska then filed a notice of appeal of the final judgment of dismissal and the post-judgment motions.

While the post-judgment proceedings in the first action were.taking place, Alyeska filed a second in rem action, Alyeska Pipeline Service Company v. BAY RIDGE, (No. A81-137, D.Alaska, filed March 24, 1981), alleging claims nearly identical to those raised in the first action. The vessel counterclaimed for damages it allegedly suffered as a result of the arrest under Rule C which it asserts is unconstitutional. After a hearing, the district court warned that the vessel would be arrested unless security was posted by the vessel owners. A letter of undertaking was subsequently filed. In November 1981 Alyeska amended its complaint to add in personam claims against the vessel owners. The second action is now pending.

ISSUES

1. Did the exoneration of the stipulation for value posted for the release of the BAY RIDGE deprive the court of jurisdiction?

2. Was the exoneration of the stipulation for value proper?

*384 DISCUSSION

A. Jurisdiction.

In an in rem admiralty action brought to enforce a maritime lien pursuant to Rule C, a vessel or other property against which the lien is asserted becomes the res or subject matter of the action. See The Brig ANN, 13 U.S. (9 Cranch) 289, 291 , 3 L.Ed. 734 (1815) (Story, J.); American Bank of Wage Claims v. Registry of Dist. Ct. of Guam, 431 F.2d 1215 (9th Cir.1970). Jurisdiction over the res is obtained by arrest under process of the court. In absence of an arrest, no decree in rem can be rendered against the res. Yokohama Specie Bank, Limited v. Chengting T. Wang, 113 F.2d 329 (9th Cir.), cert. denied, 311 U.S. 690 , 61 S.Ct. 71 , 85 L.Ed. 446 (1940).

Admiralty procedures allow an arrested vessel to be released from custody upon the posting of security. See Fed.R.Civ.P. E(5) (Supplemental Rules for Admiralty and Maritime Claims). The stipulation for value, bond or other security is substituted for the vessel as the res subject to the court’s jurisdiction. J.K. Welding Co. v. Gotham Marine Corp., 47 F.2d 332 (S.D.N.Y.1931). A plaintiff’s lien for the claims alleged against the vessel is transferred to the security posted. See generally, G. Gilmore and C. Black, The Law of Admiralty, §§ 9-89 at 796-801 (2d ed. 1975).

In the absence of fraud or misrepresentation, the release of a vessel upon the posting of security discharges the lien against the vessel. United States v. Ames, 99 U.S. 35 , 25 L.Ed. 295 (1879); Southern Oregon Production v. Oil Screw SWEET PEA, 435 F.Supp. 454, 459 (D.Or.1977).

The exoneration of security in this case deprived the court of jurisdiction. The stipulation for value, standing in place of the vessel as the res in this action, was released. There is nothing currently before the court on which to impose a decision. The Supreme Court has stated:

Mills v. Green, 159 U.S. 651, 653 , 16 S.Ct. 132, 133 , 40 L.Ed. 293 (1895).

In Canal Steel Works v. One Drag Line Dredge, 48 F.2d 212 (5th Cir.), cert. denied, 284 U.S. 647 , 52 S.Ct. 29 , 76 L.Ed. 550 (1931), an arrested vessel was released after the district court dismissed a claim against it on jurisdictional grounds. The plaintiff appealed but did not file a supersedeas bond. Granting a motion to dismiss the appeal the court stated: “By failure of appellant to obtain supersedeas, the seizure was released, and there is now no subject matter upon which the judgment of the court could operate and give relief to appellant. The case has become moot.” 48 F.2d at 213 . This court adopted the rule of Canal Steel Works in Martin v. The BUD, 172 F.2d 295 (9th Cir.1949). We applied the rule to the release of a jurisdictional substitute for a vessel in American Bank of Wage Claims v. Registry of Dist. Ct. of Guam, 431 F.2d 1215 , 1218 (9th Cir.1970). Accord, Bank of New Orleans and Trust v. Marine Credit Corp., 583 F.2d 1063, 1068 (8th Cir. 1978). In the case at bar both the vessel and its jurisdictional substitute have been released. Unless the release of the security was improper we are without jurisdiction.

B. Exoneration.

Alyeska argues that this case falls directly under the rule articulated in The RIO GRANDE, 90 U.S. (23 Wall.) 458 , 23 L.Ed. 158 (1874). The RIO GRANDE was arrested and placed in the custody of the U.S. Marshal. An appeal was taken from the district court’s dismissal of the plain *385 tiff s claims. On plaintiff’s motion, a stay of the proceedings in the district court was granted. While the stay was still in effect, the district court improperly allowed the RIO GRANDE to be released from the Marshal’s custody. Upon a claim that the release of the vessel destroyed in rem jurisdiction; the Supreme Court held that the improper release did not destroy jurisdiction. 1

Alyeska argues that the exoneration of the security was improper because the district court ignored the automatic stay provision of Fed.R.Civ.P. 62(a). 2 Fed.R.Civ.P. 62(a) imposes an automatic stay of enforcement for ten days after the entry of a judgment. 3 Alyeska argues that Rule 62(a) should have prevented the exoneration until at least March 27, ten days after entry of the court’s judgment. Alyeska contends that this would have given it sufficient time to move to block exoneration and thereby preserve the jurisdiction of the court on appeal.

Fed.R.Civ.P. A (Supplemental Rules for Admiralty and Maritime Claims) provides that “the general Rules of Civil Procedure for the United States District Courts are also applicable to the [admiralty] proceedings except to the extent that they are inconsistent with these Supplemental Rules.” If an admiralty rule permits the exoneration prior to the expiration of the ten day automatic stay then Alyeska’s arguments regarding application of Rule 62(a) must fail.

Fed.R.Civ.P. E(5)(c) (Supplemental Rules for Admiralty and Maritime Claims) governs the release of security from the hands of the court. It provides in relevant part that “no property in the custody of the marshal or other officer of the court shall be released without an order of the court; but such order may be entered as of course by the clerk ... upon the dismissal or discontinuance of the action... . ” Fed.R. Civ.P. E(5)(c) (emphasis added). Exoneration of security in the admiralty context is a ministerial act by the clerk of the court as a matter of course upon termination of the action. Since the Rule 62(a) automatic ten-day stay is inconsistent with Rule E(5)(c), Rule 62(a) must give way. Fed.R.Civ.P. A.

When plaintiffs choose to proceed in rem they must take the necessary precautions to ensure that jurisdiction of the court is preserved. Plaintiffs always have the option of bringing these actions in personam as well as in rem, which would foreclose the loss of jurisdiction. Plaintiffs can also ask the trial judge to stay imposition of the judgment until they can move to preserve the jurisdiction of the court. If plaintiffs fail to exercise either of these options, they still have a chance to preserve jurisdiction by posting their own security before the security of the defendant is released. Given these alternatives, plaintiffs are not denied the opportunity to the meaningful exercise of the right to appeal by permitting release of the res at any time following termination of the case.

CONCLUSION

Since exoneration was proper, The RIO GRANDE rule does not apply. Since the stipulation for value was the substituted res before the court, its exoneration deprives this court of jurisdiction. We therefore dismiss the appeal without considering the merits of the district court’s decision. Our decision in no way precludes the litigation of any issues pending before the district court in Alyeska Pipeline Service Co. v. The *386 Vessel BAY RIDGE, D.C.Civ. No. A81-137 (filed March 24, 1981).

The Maritime Law Association of the United States submitted a brief amicus curiae in support of Alyeska. We recognize the expertise of amicus and appreciate their participation.

. “We hold the rule to be that a valid seizure and actual control of the res by the marshal gives jurisdiction of the subject matter, and that an accidental or fraudulent or improper removal of it from his custody ... does not destroy jurisdiction. In the present case, the order for restoration was in direct violation of the statute regarding appeals, and did not operate to destroy the jurisdiction of the circuit court.” The RIO GRANDE v. Otis, 90 U.S. (23 Wall.) 458, 465 , 23 L.Ed. 158 (1874).

. Alyeska also argues that Local Rule 5 was ignored. The same arguments that justify not following Rule 62 also justify not following Rule 5. A separate discussion of Rule 5 has therefore been omitted.

. “Except as stated herein, no exception shall issue upon a judgment nor shall proceedings be taken for its enforcement until the expiration of ten days after its entry.” Fed.R.Civ.P. 62(a).
