How Shipwreck Artefacts Are Documented

Shipwreck provenance is not established by marine growth, corrosion or a convincing story about a diver.

The documentary chain should begin at recovery.

For material recovered in UK territorial waters, or recovered elsewhere and brought into UK territorial waters, the Receiver of Wreck system provides an important part of that chain. Separate protections can also apply to designated historic wrecks and military remains.

A collector looking at recovered maritime material should therefore expect more than a certificate written at the point of sale.

Recovery should be identifiable

The most useful record states where and when the object was recovered and, where known, the wreck from which it came.

Precise coordinates may be withheld from a public sales catalogue for site protection reasons, but they should exist in the underlying recovery file where appropriate.

Photographs taken at recovery, dive logs, archaeological records and contemporaneous inventories are much stronger than a later statement that an object “came from a wreck off Cornwall”.

The object should also make sense in relation to the vessel. Cargo, fittings, navigational instruments and personal material all have different evidential possibilities.

In UK waters, the Receiver of Wreck is central

GOV.UK guidance states that recovered wreck material must be reported to the Receiver of Wreck within 28 days.

“Wreck material” can include parts of a vessel, cargo and equipment. The reporting process gives the legal owner an opportunity to establish title and may also allow a lawful salvor to receive a salvage award.

Owners normally have one year from the report to prove ownership. If wreck from UK waters remains unclaimed after the statutory period, it generally becomes property of the Crown or a Crown grantee. The Receiver can then deal with it under the statutory process.

For a later collector, Receiver correspondence and the associated droit or report reference can be some of the most useful documents in the file.

They show that the material passed through the process designed to resolve ownership rather than simply disappearing from the seabed into private hands.

Not every wreck can lawfully be disturbed

The law changes significantly when a protected site is involved.

Historic England explains that within the restricted area around a wreck designated under the Protection of Wrecks Act 1973, it is a criminal offence without the appropriate licence to tamper with, damage or remove part of the vessel or objects formerly contained in it. Diving or salvage operations directed at the wreck are also controlled.

Military wrecks require separate attention. The Protection of Military Remains Act 1986 protects crashed military aircraft and allows vessels and sites to receive statutory protection. GOV.UK guidance describes protected places as effectively “look but do not touch” unless the relevant authority permits activity.

An object can therefore be physically recoverable and still not be lawfully recoverable.

Title and recovery authority are different questions

A salvage operation can be properly authorised while the recovered object still belongs to somebody else.

Conversely, an owner may have title to wreck material while recovery from a protected location requires a licence.

Good documentation keeps those questions separate. We want to know who authorised the recovery, who owned the wreck or cargo, how any salvage claim was resolved and how the object subsequently transferred.

The phrase “legally salvaged” is too vague on its own.

Conservation records are part of provenance

Objects raised from salt water often need substantial conservation.

Metals can continue to deteriorate after recovery if chlorides remain. Organic materials can distort or collapse if they dry without appropriate treatment. Concretions may hide the original surface and sometimes preserve evidence that is lost through careless cleaning.

For collecting purposes, conservation history matters for two reasons.

First, it affects physical stability. Second, it explains why the object looks the way it does now.

A heavily conserved artefact can be entirely legitimate and historically important. The treatment should simply be recorded. Desalination, electrolytic reduction, consolidation, replacement material and coatings should not disappear from the catalogue history.

What we expect in a shipwreck dossier

The ideal file combines recovery records, Receiver of Wreck documentation where applicable, evidence of title, licences or permissions where required, photographs before and after conservation, conservation notes and the subsequent chain of ownership.

Older material will not always have a perfect archive. That does not justify replacing missing records with certainty.

If the wreck attribution is probable rather than proven, the catalogue should say so.

See the Shipwreck & Maritime collection for the standard we use when considering recovered maritime material.
