In U.S. waters, you may often dive, photograph, measure, or record a publicly owned historic wreck without a permit when you do not disturb it. Touching, moving, breaking, excavating, penetrating in a damaging way, or removing an artifact is a different activity: it normally requires written authorization from the agency or entity that owns or manages the site. National marine sanctuaries, sunken military craft, federal or Indian lands, state submerged lands, and specially protected wrecks such as RMS Titanic can impose additional or stricter requirements.
The legal dividing line is disturbance
The first question is not whether you hold a diver certification or own suitable equipment. It is what you intend to do to the wreck and its surrounding archaeological deposits.

Activities that may fit recreational access
The National Park Service’s Abandoned Shipwreck Act guidance describes a baseline for publicly owned shipwrecks: a person should generally be able to dive on, inspect, study, explore, photograph, measure, record, fish at, or otherwise enjoy the wreck when the activity does not disturb or remove any part of the wreck or its immediate environment. This is a general access principle, not a blanket permission for every site.
Even an apparently passive dive can be restricted by a sanctuary closure, a military-craft protection rule, a state underwater-park rule, a no-entry order, a mooring requirement, or another site-specific condition. Check the current rule for the exact wreck before entering the water.

Activities that normally need authorization
Recovery and archaeological work are regulated because a wreck is an archaeological site, not merely a collection of objects. Moving an artifact, lifting a cannon, digging in sediment, cutting a structure, breaking concretion, anchoring on the site, or otherwise altering the wreck or its immediate environment can require a permit, license, contract, or separate written approval. Penetrating a wreck is especially risky when it damages structure or disturbs associated objects; an agency may treat that as disturbance even if nothing is removed.
Identify who controls the site
Permit requirements follow ownership, jurisdiction, and the location of the wreck. A GPS position alone is not enough: boundaries for state submerged lands, federal property, sanctuaries, and protected wreck zones can overlap.
| Wreck setting | Typical controlling authority | What to expect |
|---|---|---|
| Qualifying abandoned wreck on state submerged lands | State historic-preservation and underwater-archaeology authorities | The Abandoned Shipwreck Act transfers title to qualifying categories of wrecks to the state. Recreational exploration is contemplated, while recovery must follow the state’s historical and environmental requirements. |
| Federal public or Indian lands | The federal land manager for that property | Excavation or removal of archaeological resources generally requires an Archaeological Resources Protection Act (ARPA) permit under 43 CFR Part 7 and any agency-specific rules. |
| National marine sanctuary | NOAA’s Office of National Marine Sanctuaries | Historical-resource activities can require a sanctuary permit. Sanctuary rules can prohibit disturbance or artifact recovery even where ordinary diving is open. |
| Sunken U.S. military craft | Department of the Navy, commonly through the Naval History and Heritage Command | The Navy generally leaves these wrecks in place. Archaeological investigations or other disturbance require the Navy’s authorization when the activity falls under its jurisdiction. |
| RMS Titanic wreck or wreck site | Secretary of Commerce under the U.S.–U.K. agreement and the federal statute implementing it | Section 113 of the Consolidated Appropriations Act of 2017 creates a special authorization regime for any activity that physically alters or disturbs the wreck or site. |
State-owned abandoned shipwrecks
The Abandoned Shipwreck Act (ASA) covers qualifying abandoned wrecks in rivers, lakes, and coastal waters. The federal government asserted title to three broad categories: wrecks embedded in state submerged lands; wrecks embedded in protected coralline formations; and wrecks on state submerged lands that are listed or eligible for the National Register of Historic Places. The statute transfers title to the state.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
States are expected to preserve recreational exploration while allowing appropriate public or private recovery that is consistent with historic values and environmental integrity. That means a diver cannot assume that finding an old object creates a right to keep it. The state’s underwater-archaeology or historic-preservation office determines whether a proposed project is acceptable and which instrument is used.

Where to start with a state wreck
Contact the state historic-preservation office and its underwater-archaeology office before planning recovery. If the state has no dedicated underwater office, ask the appropriate state archaeology office. Request the current application packet and written confirmation that the agency has jurisdiction over the coordinates you intend to work.
A state may issue a permit, license, or contract rather than a generic “salvage permit.” The document can define the precise area, methods, artifacts covered, reporting schedule, conservation standards, ownership of recovered material, and where objects must be curated. Do not mobilize a vessel or advertise a recovery project until those terms are clear.
Federal public and Indian lands
For wrecks located on covered federal public or Indian lands, the National Park Service directs managers to evaluate archaeological recovery under ARPA, its implementing regulations in 43 CFR Part 7, and the particular agency’s rules. Excavating or removing archaeological resources is the regulated threshold.

National marine sanctuaries
NOAA’s National Marine Sanctuaries Act framework adds a separate layer of protection. NOAA states that disturbing a sanctuary site or recovering artifacts without a permit is illegal. Historical-resource activities include work on maritime heritage and archaeological resources, even when a diver believes the object is loose or abandoned.
Sanctuary permits are considered for defined purposes such as research, protection, public education, or scientific understanding. A request should explain the research question or management need, the exact site, proposed equipment and methods, how disturbance will be minimized, and how recovered material will be conserved and reported. Ordinary recreational access does not convert into a recovery authorization simply because the wreck is visible or popular.
Florida Keys example
Sanctuary rules illustrate why a location check matters. NOAA’s Florida Keys guidance states that it is illegal to damage a historical resource, disturb a site, or recover artifacts without a permit. A wreck that can be visited by recreational divers may therefore remain closed to touching, collecting, or site-altering activity.

The Navy’s permitting program covers archaeological investigations and other activities directed at sunken military craft under Department of the Navy jurisdiction. The Navy says more than 20,000 ships and aircraft are sunk, so the fact that a craft is old, abandoned, or outside a naval base does not by itself remove protection.

The Navy generally leaves military wrecks in place and undisturbed. Its published examples distinguish non-disturbing recreation from research: diving on or photographing a sunken military craft does not require a Navy permit as long as the wrecksite and associated artifacts are not disturbed. A research permit can authorize disturbance, removal, or injury when necessary for cultural-resource protection, scientific research, or public education.
What to ask the Navy
Provide the wreck’s name, coordinates, date and purpose of the proposed activity, equipment, and whether any contact, sampling, mapping, recovery, or penetration is planned. Ask whether the craft falls under Department of the Navy jurisdiction and whether another agency also controls the surrounding seabed or sanctuary. Written confirmation is preferable to relying on a verbal interpretation from a dive operator.
RMS Titanic has its own federal authorization rule
Titanic is not handled like an ordinary abandoned wreck. Section 113 of the Consolidated Appropriations Act of 2017 provides that no person may conduct research, exploration, salvage, or other activity that would physically alter or disturb the wreck or wreck site unless authorized by the Secretary of Commerce under the U.S.–U.K. agreement.
This language reaches activities described as research or exploration, not just commercial salvage. Any plan involving remotely operated vehicles, sampling, attachment of equipment, entry, cutting, lifting, or contact that could alter the wreck or site should be treated as requiring the federal authorization process. A sightseeing dive, where legally available, is not permission to touch or collect.

What a professional recovery application must address
Exact requirements vary by jurisdiction and project, but National Park Service guidance identifies the elements a responsible state recovery permit, license, or contract should require:
- Qualified archaeological leadership: professional underwater-archaeology supervision appropriate to the site, methods, and period.
- Complete site documentation: a baseline survey, position data, measured drawings or photogrammetry where appropriate, condition assessment, and a record of the surrounding context before anything is moved.
- Artifact recording: unique identifiers, provenience, dimensions, materials, photographs, field notes, and a chain of custody for each recovered item.
- Conservation: a funded plan for desalination, stabilization, storage, and long-term care. Waterlogged wood, iron, ceramics, and composite objects can deteriorate rapidly after recovery.
- Reporting: progress reports, a final technical report, maps, databases, conservation records, and disclosure of methods and results on the schedule set by the authority.
- Curation and ownership: an approved repository and clear terms for title, loan, display, access, and future conservation of recovered material.
- Other permits: compliance with all additional state and federal requirements, including those for vessels, protected species, environmental review, human remains, tribal interests, or sanctuary operations when applicable.
An application that describes only the object you hope to retrieve is incomplete. Agencies evaluate the archaeological context, the likelihood of damage, the competence of the team, and what will happen to material for decades after the dive.
A practical permit process
- Define the activity in writing. Separate observation, photography, mapping, sampling, excavation, penetration, lifting, and permanent removal. State whether any tool will contact the wreck or seabed.
- Fix the site location. Record coordinates, depth, state or federal boundary, sanctuary status, and whether the wreck is a military craft or another specially protected site.
- Identify the owner and manager. Contact the state underwater-archaeology or historic-preservation office, federal land manager, NOAA sanctuary superintendent, or Navy/Naval History and Heritage Command as appropriate.
- Request the current rules and application packet. Ask which permit, license, contract, or authorization applies and whether separate agencies must approve the same work.
- Assemble the archaeological team and plan. Include qualifications, survey and recovery methods, risk controls, conservation facilities, curation arrangements, budget, schedule, and a public-reporting plan.
- Resolve vessel and environmental approvals. Confirm anchoring, mooring, protected-species, navigation, tribal, and other site conditions before submission.
- Wait for written authorization. Read the approved area, dates, methods, artifact list, monitoring terms, stop-work conditions, and reporting deadlines. A permit for survey does not automatically authorize excavation or recovery.
- Work exactly to the authorization. Record every action and stop if conditions change, an unexpected human remain is found, or the work would exceed the approved disturbance.
- Conserve, report, and curate. Deliver artifacts and documentation to the repository and agency specified in the authorization, and meet all post-fieldwork deadlines.
Common mistakes that turn a legal dive into unauthorized recovery
- “It was loose, so I could take it.” An unattached object can still be an archaeological resource or sanctuary historical resource.
- “The wreck is abandoned, so nobody owns it.” The ASA can transfer title to a state, and military or specially protected wrecks remain subject to separate authority.
- “I am only documenting it.” Drilling, scraping, attaching lights or scale bars, moving sediment, or entering a fragile structure can exceed non-disturbing documentation.
- “A state permit covers the whole site.” A sanctuary, federal land manager, Navy, or Titanic authorization may still be required.
- “A verbal okay is enough.” Carry the written permit or agency determination on the vessel and ensure the crew understands its limits.
- “We will figure out conservation later.” Recovery without a funded conservation and curation pathway can damage objects permanently and prevent an agency from approving the project.
Before entering the water
For a non-disturbing recreational dive, confirm that the wreck is open, that no sanctuary or state closure applies, and that your equipment and anchoring method will not damage the site. For any contact, movement, excavation, penetration that could harm the wreck, sampling, or removal, pause the dive plan and obtain the applicable written authorization from the managing authority. If the site’s ownership or status is uncertain, treat it as protected until the agency responsible for the coordinates confirms otherwise.
