This is an appeal and cross appeal of the district court’s resolution, on remand from this court, of competing claims to a 42-foot motorized yacht, known variously as the Lady B, the Lady B Gone, and the Cent’Anni (the vessel). The vessel’s owners, David and Joan Mullane, appeal the district court’s rejection of their claim to a lien on the vessel. Adele Chambers and Jean Farese, who seized the vessel to satisfy debts of the vessel’s previous owner, appeal the district court’s order that they reimburse the Mullanes for storing the vessel during the course of the litigation. We affirm.
I.
The facts have been recounted elsewhere. This case has been tried twice, by two different district court judges, each of whom published an opinion.
Mullane v. Chambers,
In July 1998, the Mullanes bought the vessel from a trust established by Dr. David Murphy and his wife. As consideration, the Mullanes paid $98,117 to Eastern Bank to discharge the preferred ship’s mortgage on the vessel in favor of the bank, 1 paid $2,000 cash to Murphy and assumed a $40,000 lien Murphy owed to his own company.
The vessel was federally documented and listed on the registry maintained by the United States Coast Guard. 2 In the normal course of maritime affairs, transfer of the vessel and discharge of the mortgage should have been recorded immediately with the Coast Guard, in which case the public record would have shown that the Mullanes, not the Murphys, owned the vessel. 46 U.S.C. §§ 12101-12124, 31321. For whatever reason, however, the sale and discharge were not recorded until September. In the interim — for all of August — the public record showed erroneously that the Murphys owned the vessel, subject to a mortgage in favor of Eastern Bank.
At the time he sold the vessel to the Mullanes, David Murphy was indebted to Chambers and Farese, both of whom had loaned him money. Chambers had obtained a $70,132 writ of execution against Murphy, and Farese a writ for $27,612. But neither Chambers nor Farese had attached any claim to the vessel until late August, when, acting on the information in the public record, they arranged for sheriffs deputies to seize the vessel.
*135 Chambers and Farese learned about the transfer from the Murphys to the Mul-lanes and the mortgage discharge hours after the seizure. Nonetheless, they elected to press their claim to the vessel rather than attempt to satisfy Murphy’s debt with property that actually belonged to him. Indeed — according to their own statements — upon learning that the Eastern Bank mortgage on the vessel had been discharged, Chambers and Farese abandoned their plans to seize Murphy’s condominium, which they also had arranged for the sheriffs deputies to levy. They believed that the additional equity in the vessel available after the mortgage discharge would make any seizure of Murphy’s own property unnecessary.
The Mullanes sued Farese, Chambers, and the Sheriffs Department that had seized the vessel. They claimed that the seizure had been illegal, that they were entitled to unencumbered ownership of the vessel, and that they were owed compensation for damage to the vessel that occurred during the seizure. The case landed on the admiralty docket of the district court.
See Mullane,
After the first trial in this case, the district court found that the Mullanes were bona-fide purchasers of the vessel who had no notice of Chambers and Farese’s claims. The court also concluded that the seizure of the vessel was improper under Massachusetts law. The district court restored the Mullanes’ ownership rights and ordered Chambers and Farese to pay $100,000 in punitive damages to the Mul-lanes, for what the district court termed their “wanton and reckless” disregard of the Mullanes’ rights. 3
We vacated and remanded, concluding that Chambers and Farese were entitled to rely on the public record unless they had actual notice of the transfer to the Mullanes, and that they had adhered to Massachusetts law in seizing the vessel.
See Mullane,
On remand, the district court found that Chambers and Farese had no actual or constructive notice of the Mullanes’ purchase at the time of the seizure (though they did within hours thereafter). 4 Conse *136 quently, the district court determined that Chambers and Farese had a valid claim on the vessel. The parties do not contest this determination on appeal. Because the district court found that Chambers and Farese had valid liens on the vessel, it did not need to reexamine the fraudulent transfer issue.
Recognizing that application of 46 U.S.C. § 31321, the vessel documentation statute, would yield a “harsh” penalty on the “innocent” Mullanes, the district court invited briefing on whether the Mullanes might be entitled to relief from that application, on admiralty or analogous state law grounds. The Mullanes suggested only that they were entitled to a maritime lien on the vessel, equal in value to the Eastern Bank mortgage that they had discharged. The district court determined that no such maritime lien existed.
■ Finally, the court ordered, “in the interest of equity,” that Chambers and Farese “reimburse the Mullanes for all reasonable storage and insurance costs of the vessel incurred since the levy.” The Mullanes had incurred such charges by storing the vessel at various marinas during the course of the litigation as they tried to clear title to the vessel.
II.
A. The Mullanes’ Appeal
At the conclusion of the second trial in this case, the district court opined that relief might be possible on grounds that, in light of Chambers and Farese’s seizure, the Mullanes’ discharge of the Eastern Bank mortgage had unjustly enriched Murphy. Seeking to resolve the issue, the district court gave very specific instructions:
I ... need to have briefed the issue of ... thfe role that Dr. Mullane’s discharge of the preferred ships mortgage plays here. I’m not here talking about simple appeals to equity.... 7 want to know everything there is to know about this type of circumstance either under the federal recording statute, and if we can’t find that let’s go to the common law of the several states which have recording . statutes. When a creditor seeks to levy on encumbered assets of the debtor, the creditor takes those assets encumbered. Here there appears no evidence but that Dr. Mullane was innocent.... Dr. Mullane may be entitled to ... the equivalent of a preferred ship’s mortgage....
Tr. Day 2, pp. 33-34 (emphasis added).
Whether or not an equitable subordination argument could have been made on these facts, it was not made before the district court or before us, and so is waived.
Cf. Maryland National Bank v. The Vessel Madam Chapel,
Under § 31342(a), a person provides a “necessary” by furnishing “goods or services ... necessary to the continued operation of the vessel,” in a manner that “facilitates the flow of commerce.”
Payne v. S.S. Tropic Breeze,
The rule of advances, like the doctrine of necessaries, facilitates reimbursements of those who allow a vessel to perform its functions. The difference is that the rule of advances provides protection not to the person furnishing “necessaries,” but rather to a third person who pays for the goods and services that would have given rise to a statutory maritime lien, on an assurance that the vessel will be responsible for the debt.
Wilkins,
On appeal, the Mullanes do not quibble with the district court’s conclusion that their discharge of the Eastern Bank mortgage did not constitute a “necessary” but seek relief only pursuant to the rule of advances. We see at least two basic barriers to the Mullanes’ rule of advances theory, both also fatal to the Mullanes’ § 31342(a) argument.
First, maritime liens, created pursuant to the rule of advances or any other theory, are intended to safeguard the interests of “strangers to the vessel,” not vessel owners or those who can control the vessel’s affairs.
Sasportes v. M/V Sol de
*138
Copacabana,
Second, even assuming that the Mullanes’ purchase of the vessel effected a maritime lien by “advance,” the Mullanes already have received the appropriate compensation for that advance: ownership of the vessel. The Mullanes entered into a contract whereby they agreed to supply the funds to extinguish the Eastern Bank mortgage in exchange for the vessel. Nothing else was promised. The Mullanes’ ownership rights were compromised not because the vessel’s operator or owner failed to repay them for an advance, but because, after they had been repaid in full- and after any maritime lien had been extinguished by satisfaction-they neglected to protect their rights by documenting their purchase.
B. Chambers and Farese’s Appeal
The district court granted the Mullanes’ motion for reimbursement for the cost of storing the vessel during litigation, an expense they documented to the district court. Chambers and Farese contend that the district court abused its discretion in so doing.
It is well established that admiralty courts may award storage charges on equitable grounds.
See The Poznan,
Essentially, Chambers and Farese argue that it was an abuse of discretion for the court to award storage charges because the Mullanes, having posted a bond, could have enjoyed the use of the vessel during *139 the litigation. However, there is no evidence that the Mullanes did employ the vessel while the case was pending. The record indicates that the vessel was damaged severely in the initial seizure, and that its usefulness since has been limited. In any case, we are not persuaded that the district court abused its discretion in allowing the motion for storage costs.
Storage costs were an inevitable consequence of the litigation that we have recounted. As we have discussed, vessels subject to ownership disputes ordinarily are held in the custody of the court during litigation.
See
Fed.R.Civ.P. E; 28 U.S.C. § 1921(a)(1)(E) (2000). If the Mullanes had not posted security and served as substitute custodians, the court would have been entitled to reimbursement for its storage costs.
Id.
And the court’s
custo-dia legis
expenses would have created a right superior to Chambers and Farese’s lien.
See
46 U.S.C. § 31326(b)(1); 2-IV Benedict on Admiralty § 51 (2005). There is no indication on the record that the storage costs incurred by the Mullanes were any greater than those that would have been incurred by the court. The Mullanes had an interest in maintaining the damaged vessel (which they intended to use personally). Their expenditures to insure and store the vessel during litigation benefitted all parties. These were good enough reasons for the district court to appoint them as the vessel’s custodians and to reimburse them for storage charges.
See Donald Forsht Assoc.,
Chambers and Farese also appear to argue that the Mullanes should not be entitled to storage charges because they initiated, but eventually lost, this lawsuit. Again, we are unpersuaded. This was not a frivolous suit. It was a close case that required two district court trials, the first of which the Mullanes won. The district court found that the Mullanes were “innocent” parties, who fought at length, if unsuccessfully, to prevent their own property from being seized by another person’s creditors. Their claim to the vessel was a plausible one. In light of these facts, we discern no abuse of discretion in reimbursing their storage charges.

The district court’s order is affirmed in all respects. The parties shall bear their own costs and fees.
So ordered.
Notes
. A preferred ship's mortgage is a statutorily-created lien that can be publicly registered, see infra note 2, and can be enforced in an admiralty court. See 46 U.S.C. § 31322 et seq.
. The Coast Guard maintains a "national form of registration” for vessels larger than five net tons. Vessels like the one involved in this case, larger than five net tons but not involved in any commercial enterprise, may be registered at the option of the owner. See 46 U.S.C. § 12101 et seq. See also National Vessel Documentation Center: Frequently Asked Questions, at http://www.uscg.mil/hq/g-m/vdoc/faq.htm (last visited Jan. 24, 2006).
. The district court found that no relief was warranted on the Mullanes' claims against the sheriff's department.
. After our remand, the case was assigned to a different district court judge than the one who presided at the first trial. Due to that judge’s busy schedule, the case was reassigned to the Chief Judge, who presided at the second trial and entered the judgment that we now review.
. Chambers and Farese also argue that Dr. Mullane forfeited the right to storage charges because, they contend, he documented the vessel’s home port as in New Hampshire, where he intended to move it, rather than in Massachusetts, where it was at the time of the seizure, to avoid paying state sales tax on it. We will not entertain this contention. Before it allowed the Mullanes' petition for storage charges, the district court gave Chambers and Farese an opportunity to submit written objections. Chambers and Farese submitted a post-trial memorandum that did not include any reference to the sales tax issue. Accordingly, they waived the opportunity to make the argument they now attempt.
