Prepared for Vince Cate / seastead.ai — Anguilla, BWI
⚠️ Disclaimer: This document provides general informational guidance only and does not
constitute legal advice. Laws and regulations change. You should consult qualified maritime lawyers,
Anguillan solicitors, and relevant government departments before taking action.
Some information below reflects the state of affairs as of early 2025 and may need verification.
1. Pre-Launch Legal Steps in Anguilla
You are in a genuinely pioneering position — there is no standard checklist for launching
a seastead from a privately owned, officially zoned shipyard in a British Overseas Territory.
However, the following steps are strongly recommended before you put anything in the water.
1.1 Confirm Your Zoning & Permits
Get the zoning decision in writing — make sure the Planning Department's
"shipyard" designation is issued as a formal written decision or certificate, not just verbal
confirmation. This protects you if officials change.
Confirm whether shipyard zoning explicitly permits vessel assembly and launch,
not just storage or repair.
Ask if there are conditions attached to the zoning (noise, hours of operation,
environmental mitigation, etc.).
Check whether adjacent land or foreshore rights are under the Crown (common in British
Overseas Territories) and whether you need a foreshore licence or
seabed lease to extend any structure into the water during launch.
1.2 Environmental Compliance
Contact the Anguilla Department of Natural Resources and Environment (DNRE)
— launching a novel structure near the port may trigger an environmental review.
Anguilla has coral reef protections. If your site is near reef, you will need an
environmental impact assessment (EIA) or at least a letter of no-objection.
Confirm compliance with the Anguilla Environmental Management (Protection and
Pollution) Act regarding waste discharge during construction and after launch.
Ballast water management should be documented even for a non-self-propelled structure
if it will ever be towed to sea.
1.3 Port Authority Coordination
Contact Anguilla Port Authority early. You are next to the port — they
have authority over vessel movements in the harbour approaches.
You will likely need formal approval or at minimum a notification for the launch operation,
especially given crane use near the port.
If the seastead is to be moored offshore, you will need a mooring permit
or anchorage approval.
Discuss a marine traffic plan for launch day.
1.4 Construction Safety & Inspections
Even though Anguilla may not have specific regulations written for floating structures,
the Planning Department may apply the building code during construction on your land.
Document all fabrication quality (especially from China) — get mill certificates for steel,
weld inspection records, pressure test records for any watertight compartments, etc.
Consider hiring an independent marine surveyor during assembly to certify structural
integrity before launch. This protects you legally if anything goes wrong.
1.5 Insurance
Obtain marine construction insurance (also called builder's risk) before
you begin assembly.
Ensure the crane operator and any contractors carry adequate liability insurance.
After launch, you will need hull and machinery and
protection & indemnity (P&I) cover. This may be challenging for
a novel structure — speak to a specialist marine insurer or broker.
1.6 Labour & Immigration
If using Chinese technicians for assembly supervision, they will need work permits from
the Anguilla Labour Department.
If people will live aboard the seastead, particularly foreign nationals, check
with Immigration whether a residency or long-stay permit is required
(likely yes, especially if moored in Anguillan waters).
1.7 Utility Connections
If you plan to connect the seastead to shore power, water, or sewage during construction
or initial use, coordinate with Anglec (electricity) and
Anguilla Water Authority well in advance.
💡 Tip: It is worth engaging a local Anguillan solicitor with connections
to the government to serve as your liaison. Many of these approvals will move faster with
a trusted local professional making the calls.
Pre-Launch Legal Checklist
Written zoning confirmation from Planning Department
Foreshore/seabed licence if structure extends into water during assembly
Environmental clearance or EIA from DNRE
Port Authority approval for launch operation
Mooring permit for post-launch location
Marine construction insurance in place
Independent marine surveyor engaged
Work permits for foreign technicians
Local solicitor retained
Vessel registration (see Section 2) initiated
2. Registering the Vessel in Anguilla
Anguilla is a British Overseas Territory (BOT). As such, its shipping registry operates
under UK maritime law as adapted locally. The primary legislation is likely to follow
the Merchant Shipping Act (UK) 1995 as extended or the local
Anguilla Merchant Shipping Ordinance.
ℹ️ Key Contact: Start with the Anguilla Maritime Administration
or the relevant department within the Ministry of Infrastructure, Communications,
Utilities and Housing. Anguilla does maintain a ship registry, primarily used
for local fishing and commercial vessels.
2.1 Is It a "Ship" or a "Floating Structure"?
This is the central legal question for your registration. The distinction matters enormously:
Category
Definition (typical)
Registration Regime
Ship / Vessel
Any waterborne craft used in navigation
Ship registry (Merchant Shipping Act framework)
Floating Structure (non-navigating)
Permanently moored, no propulsion, not used in navigation
May not qualify for ship registration; may need a special licence
Mobile Offshore Unit (MOU)
Floating platform capable of moving between locations
IMO MODU Code / special classification
If your seastead is self-propelled or regularly towed between locations,
it is more likely to be treated as a vessel. If it is permanently moored in one spot
with no navigation intention, some registries will not register it as a ship at all.
You may need to argue for registration as a houseboat, floating platform,
or novel marine structure.
2.2 Typical Requirements for Ship Registration in a BOT
Ownership proof — bill of sale, builder's certificate, or similar
document proving you own the vessel.
Tonnage measurement — a licensed measurer must determine gross
and net tonnage (GT/NT) according to the 1969 Tonnage Convention. This affects
fees and classification requirements.
Safety certificates — for vessels over certain sizes (often 24m LOA
or 500 GT), SOLAS-compliant certificates are required for life-saving appliances,
fire safety, radio, etc. Smaller vessels have simpler requirements.
Survey & inspection — a flag state surveyor or recognized
organization (classification society) must inspect and certify the vessel as
seaworthy (or at minimum, safe for its intended use).
Owner eligibility — in British registries, the owner typically
must be a British national, BOT resident, or a company incorporated in a BOT or
UK. You may need to form an Anguillan company to hold the vessel.
Name reservation — the vessel name must be unique in the registry.
Registration fee — varies by tonnage.
Insurance certificate — proof of P&I or liability insurance
is increasingly required.
2.3 Practical Challenges for a Seastead
Anguilla's registry officials may simply never have processed an application
for a floating residential platform — expect questions and possible delays.
You may need to educate the registry on how similar structures have been
registered elsewhere (Panama is your best example — see Section 3).
The flag state administration must assign a flag state surveyor
or delegate the survey to a Recognized Organization (RO) such
as Lloyd's Register or Bureau Veritas. Anguilla may already have RO agreements
in place for its ship registry.
If Anguilla's registry cannot accommodate the structure, you could still
incorporate in Anguilla but register the vessel elsewhere.
💡 Strategy: Approach the Anguilla Maritime Administration
with a detailed technical description and reference the Panama SeaPod/Ocean
Builder registrations as precedent. Ask specifically what category they would
place your structure in and what survey/certification they would require.
Get that answer in writing before you invest in classification.
3. Panama as an Alternative Registration Jurisdiction
Panama operates one of the world's largest open registries (flag of convenience)
and has indeed registered Ocean Builder's SeaPods and at least
one other novel floating structure. This makes Panama the most proven option
for seastead registration as of 2024–2025.
3.1 Why Panama Works
Panama's Autoridad Marítima de Panamá (AMP) has a flexible,
commercially-oriented approach to novel vessel types.
Panama accepts registration of foreign-owned vessels with minimal national
connection — you do not need to be Panamanian.
They have registrar staff experienced with unusual structures.
Fees are competitive and the process is largely handled by local
representantes (Panamanian maritime lawyers/agents) who do this
routinely.
Panama is a full IMO member state and can issue SOLAS and other
international certificates.
Minimum safety equipment (depends on vessel category assigned)
Appointment of a Panamanian representante legal (mandatory)
Annual registration fee (based on GT)
Inspection by a surveyor approved by AMP
3.3 Practical Notes
Contact Ocean Builder directly — they have already navigated
this process and their Panamanian legal team may be able to assist you or
at least advise.
Panama registration does not prevent you from operating in Anguillan waters,
but you would still need to comply with Anguilla's local port and environmental
rules as a foreign-flagged vessel.
If permanently moored in Anguilla, Anguillan authorities may eventually
require local registration or at minimum a long-term mooring permit with
conditions.
4. IMO Guidelines for Non-Traditional Marine Structures
The International Maritime Organization (IMO) has developed several instruments
relevant to non-traditional or novel floating structures. No single comprehensive
"seastead code" exists yet, but the following are the most applicable:
4.1 MODU Code (Mobile Offshore Drilling Units)
The 2009 MODU Code (and its predecessors from 1979 and 1989)
governs mobile offshore units — floating platforms originally designed for
oil and gas drilling.
While your seastead is not a drilling unit, the MODU Code is the closest
existing IMO framework for semi-submersible or column-stabilized platforms.
Classification societies often use MODU Code structural standards as a
reference baseline for novel floating structures, even when the unit is
not strictly a MODU.
4.2 MSC-IMO Circular 1625 and the Goal-Based Standards
IMO's Goal-Based Ship Construction Standards (GBS)
(MSC.287(87)) establish high-level goals and functional requirements for
ship design rather than prescriptive rules. Classification societies must
demonstrate their rules meet GBS.
For truly novel structures, the goal-based approach is
the philosophically correct framework — what safety goals must be achieved,
and what technical means achieve them?
4.3 Large Yacht Code (LY3) — Possibly Relevant
If your seastead is under 500 GT and used for private residential purposes,
some flag states and classification societies may apply the
Large Yacht Code (LY3) as a useful, more accessible framework.
LY3 covers construction, stability, fire safety, and life-saving appliances
for large private yachts and may be more pragmatically applicable than
full SOLAS.
4.4 SOLAS (Safety of Life at Sea Convention)
SOLAS applies to vessels over 500 GT on international voyages. If your
structure is under 500 GT and/or does not go on international voyages,
SOLAS may not apply directly — but its standards are used as a reference.
Stability is perhaps the most critical safety requirement for any floating
structure. The 2008 IS Code (made mandatory under SOLAS)
provides criteria for intact stability that classification societies will
apply or adapt for novel structures.
4.6 IMO's Approach to Novel Structures
IMO has acknowledged that existing conventions do not neatly cover all novel
floating structures. The standard IMO pathway for a vessel/structure that
does not fit existing codes is:
Flag state responsibility — the flag state (e.g., Panama or Anguilla)
determines what standards apply, often in consultation with a Recognized Organization.
Equivalence principle — SOLAS allows flag states to accept
alternative arrangements that achieve an equivalent level of safety.
MSC approval for novel designs — for truly groundbreaking
designs, IMO's Maritime Safety Committee can be petitioned for guidance,
though this is slow and complex.

"MODU Code 2009", and "Goal-Based Standards."
Lloyd's Register (LR) is one of the world's oldest and most respected
classification societies. They have significant experience with offshore
floating structures, FPSOs (Floating Production, Storage and Offloading units),
semi-submersibles, and non-conventional vessels.
5.1 Lloyd's Register Rules Applicable to Floating Structures
LR Rule Set
Applicable To
Rules and Regulations for the Classification of Ships
Conventional ships; sections may apply to unusual vessels
Rules for Floating Offshore Installations at a Fixed Location
Rules for the Classification of Mobile Offshore Units
MODUs, semi-submersibles, jack-ups
Rules and Regulations for the Classification of Special Service Craft
Unusual vessels including novel designs; LR has used this for houseboats, barges, etc.
ShipRight Design Appraisal Procedures
Novel or first-of-class designs needing special review
5.2 The LR Classification Process for a Novel Floating Structure
Initial Enquiry / Feasibility Meeting
Contact LR's business development or technical department. Describe your
structure. They will advise which rule set they believe applies, or whether
a special novel design assessment is needed. LR has handled this many times
for FPSOs and offshore accommodation barges.
Plan Approval (Design Review)
Submit structural drawings, stability calculations, general arrangement,
construction specifications, materials certificates, machinery plans (if any),
fire safety plans, etc. LR surveyors review against applicable rules and
either approve, request modifications, or propose equivalences.
Construction Survey
An LR surveyor attends key stages of construction — steel cutting, welding,
compartment testing, machinery installation. If fabricated in China, LR has
offices there and can attend at the Chinese yard. This is actually an
advantage: LR has a large China presence.
Inclining Experiment / Stability Test
After assembly (or after significant changes), a stability test is performed
to verify calculated stability against actual floating behavior.
Launch Survey
LR surveyor attends the launch to verify the structure behaves as expected.
Classification Certificate Issued
Upon satisfactory completion of all surveys and plan approvals, LR issues
a Certificate of Classification. This is separate from
the flag state's registration but is often required by the flag state
as proof of safety.
Annual and Periodic Surveys
Classification is maintained through annual surveys and periodic
(5-year) drydocking/out-of-water inspections.
5.3 What LR Classification Achieves for You
Provides a credible, internationally recognized safety certificate that
Anguilla or Panama registrars will likely accept in lieu of their own survey.
Makes insurance far easier to obtain and likely cheaper.
Provides legal protection — if something goes wrong, you can demonstrate
you met the highest available safety standards.
Demonstrates good faith to Anguillan authorities who may be uncertain
how to handle your application.
5.4 Cost & Time Considerations
LR classification is not cheap — expect plan approval fees in the range of
several thousand to tens of thousands of USD depending on complexity,
plus survey attendance fees.
Starting the LR process before fabrication in China is
strongly recommended — getting design approval before you build is far
cheaper than retrofitting.
LR's China offices are in Shanghai, Guangzhou, Dalian, and other major
ports — attending the Chinese yard for construction surveys should be
logistically straightforward.
ℹ️ Contact Lloyd's Register:www.lr.org
Look for their "Offshore" or "Marine" business divisions. Ask specifically about
"novel floating structures" and mention you are seeking both design approval
and flag state support (Panama or UK BOT).
💡 Alternative Classification Societies to Consider:
Bureau Veritas (BV) — strong offshore experience,
very active in Caribbean region
DNV (Det Norske Veritas) — arguably the leader in
offshore floating structure rules; their "DNV-OS" offshore standards
are widely used
American Bureau of Shipping (ABS) — strong MODU and
offshore experience, US-based but global
All of these would be viable alternatives to LR. DNV in particular has
published specific guidance on novel offshore structures and floating cities.
6. The Seasteading Institute's Classification Society Efforts
⚠️ Important Caveat: The information below reflects publicly available
information as of early 2025. The Seasteading Institute's activities change over time
and some initiatives may have progressed, stalled, or pivoted. Direct contact with TSI
is essential to get current status.
6.1 Background
The Seasteading Institute (TSI), founded by Patri Friedman and Peter Thiel in 2008,
has long recognized that the lack of a classification society tailored to seasteads
is a major barrier. Existing classification societies' rules were written for
conventional ships and offshore oil platforms — not for permanently inhabited,
community-oriented floating settlements.
TSI has discussed creating or partnering with a classification body that would:
Write rules specifically for floating residential communities
Account for amenity, habitability, and community requirements beyond
pure safety/commercial ship standards
Be more accessible to small developers and self-builders
Work closely with sympathetic flag states
6.2 Status as of Early 2025
Based on publicly available information, TSI has not yet established
a fully operational, independent classification society for seasteads.
The initiative has been discussed in TSI publications and conference presentations,
but the concrete progress appears to be in early or conceptual stages. Specifically:
TSI has been in dialogue with existing classification societies about
how their rules could be adapted.
TSI worked with the government of French Polynesia
on a special economic zone concept (the Floating Island Project), though
this project fell apart around 2018 after political opposition.
TSI has published design guidelines and technical papers
on seastead design but these do not constitute a classification rule set.
The Ocean Builders team (SeaPod project in Panama) went
through Panama's registry directly and with private engineering certifiers
rather than through TSI.
As of 2024, TSI's primary focus appears to be on advocacy, research,
and community building rather than operating regulatory/certification bodies.
6.3 Could TSI Help You Within a Year?
Realistically: probably not for formal classification purposes.
Even if TSI were to announce a classification initiative tomorrow, getting an
entirely new classification society recognized by major flag states (like Panama
or even Anguilla/UK) typically takes many years of regulatory approval.
Flag states only accept surveys from their approved
Recognized Organizations (ROs), and getting RO status requires
a lengthy approval process with IMO member states.
However, TSI could potentially help you with:
Introductions to sympathetic officials in Panama and other jurisdictions
Connecting you with engineers who have designed seasteads before
Sharing design guidelines and lessons learned from previous projects
Advocacy support if you face regulatory pushback
Community and PR value for your project
6.4 Recommendation
For your timeline, use an existing, established classification society
(LR, DNV, BV, or ABS) for your formal certification needs.
Separately, engage with TSI for community support and advocacy.
Do not plan on TSI providing formal classification certification within
the next 1–2 years unless they announce a major breakthrough.

Their forums and annual conferences are good places to connect with others
who have navigated registration and certification for novel floating structures.
