Seastead Business Issues (China Fabrication → Caribbean Assembly → Caribbean Sales)

Disclaimer: This is general business planning information, not legal/tax/engineering advice. For decisions involving customs, flagging, classification, insurance, and environmental compliance, use qualified maritime counsel, a customs broker, and (ideally) a classification society or marine surveyor.

1) Define the “Product” in Commercial Terms

Decide what you are selling

Option A: “Vessel” (registered/flagged, treated as a boat/platform) — may simplify mobility but can trigger safety, equipment, crewing, and inspection requirements.
Option B: “Floating structure” (moored/anchored) — may shift compliance toward coastal/state permits and marina-style rules.
Option C: “Kit + Assembly service” — fabricate modules in China, final assembly in FTZ, then deliver as a finished unit or partially assembled.

Define standard SKUs early

Base platform + optional energy package (solar/batteries/inverters)
Propulsion package (your low-speed mixers/props), or “propulsion-ready”
Mooring package (anchors/catenary/elastic rodes) vs. customer-supplied mooring
Habitability modules (plumbing, septic/blackwater, HVAC, etc.)

2) Market & Customer Segments (Caribbean-first)

Likely early customers

Resorts (overwater suites, floating lounges, private dining, spa)
Dive / fishing operators (base station, overnight trips)
Research / environmental monitoring
High-net-worth private buyers (novelty + privacy)
Film/event rentals

What customers will ask first

Hurricane plan: relocate? sink-to-survive? tow to safe harbor? insurance?
Permits: where can it be placed and for how long?
Maintenance burden: corrosion, fouling, mooring wear, solar/battery life.
Safety: stability, egress, railings, fire suppression, electrical.
Total cost: delivery + setup + yearly operating costs.

3) Pricing & Unit Economics (Template)

Build a simple “landed cost → margin → support” model

Cost Bucket	Examples	Notes / Watchouts
China fabrication (EXW/FOB)	Steel/aluminum, floats, columns, welding, coatings, QA	Specify coating system and QA hold-points; corrosion failures kill reputations.
International logistics	Container/flat rack, breakbulk, port fees, marine cargo insurance	Oversize modules can change everything; design for containerization if possible.
FTZ/Freeport handling	Storage, cranage, yard fees, security	Long dwell time can erase duty savings.
Assembly & commissioning	Local labor, welding, electrical, solar install, testing	Define who signs off commissioning and what tests are mandatory.
Regulatory & professional	Surveyor, naval architect stamps, class guidance, legal	Budget this early; it’s often needed to obtain insurance and permits.
Delivery & installation	Towage, escort, mooring/anchors, diver time	Install is often the largest “surprise” expense.
Warranty reserve	2–5% of sales price (typical starting point)	Saltwater + novel hardware = plan for field fixes.

Practical approach: set a target gross margin that covers (1) sales + marketing, (2) support + warranty, (3) product improvements, and (4) hurricane/incident contingencies.

4) Manufacturing in China: Contracts, QA, and Risk Control

Contract structure essentials

Use clear Incoterms (e.g., FOB Chinese port vs CIF Caribbean port) and define who pays for what.
Drawings + revision control: “latest revision only” language, with sign-off.
QA hold points: material certs, weld procedures (WPS/PQR), NDT requirements, coating DFT checks, pressure/leak tests for sealed floats.
Acceptance criteria: flatness, alignment, tolerances at critical interfaces (cable lugs, column joints, prop mounts).
Remedies: rework at supplier cost, liquidated damages for schedule slips (careful), spare parts included.

Operational controls that matter

Third-party inspection in China before shipment (cheaper than fixing in the Caribbean).
Design for shipping: minimize oversize; create “shipping cradles” and lifting points.
Corrosion strategy: coatings + sacrificial anodes; define replacement intervals.

5) Shipping & Customs: Plan the Path for Each Module

Key questions for your freight forwarder / customs broker

Can the major components fit into standard containers or flat racks? If not, quote breakbulk and consider redesign for packability.
What HS codes are likely (fabricated metal structures, marine parts, solar equipment)? Classification affects duties and paperwork.
What documentation is required: commercial invoice, packing list, certificates of origin, material certificates, fumigation for wood packaging, etc.
What is the marine cargo insurance policy scope (damage, corrosion exclusions, water ingress)?

6) FTZ / Freeport / Free Trade Zone Assembly: How to Choose Locations

Selection criteria (use as a scoring checklist)

Criterion	Why it matters	How to verify
Yard capability	Need cranage, weld bays, paint/coating control, secure storage	Site visit; ask for lift plan examples and max crane capacity
Legal framework	FTZ rules, re-export rules, VAT/tax handling	Local counsel + FTZ authority guidance
Skilled labor	Marine welding, electrical, solar commissioning	Interview contractors; review past marine projects
Supply chain access	Fast access to fasteners, anodes, cables, paint, electronics	Check local suppliers; lead times; import ease
Launch & sea trials	Need protected water, towing access, safe test area	Map conditions; speak with harbor master / marina operators
Hurricane exposure & procedures	Storm risk affects schedules and insurance	Ask for yard hurricane plan; historical downtime
Reputation & compliance	Banking, payments, anti-corruption risk	Reference checks; avoid “cash-only” expectations

Candidate jurisdictions often discussed for maritime/FTZ activity in the region include places such as Panama, Freeport (Bahamas), Jamaica FTZs, Curaçao/Aruba, Dominican Republic FTZs, and Trinidad & Tobago—but the right answer depends on your specific module sizes, labor needs, and where your buyers will install.

7) Regulatory, Classification, and “Can I Put This There?”

Core business reality

Many sales will be won or lost based on whether a customer can legally install and insure the unit. Plan a compliance path that is repeatable across islands.

Topics to address up front

Vessel vs. structure determination (impacts registration, inspections, equipment requirements).
Flagging/registration strategy if treated as a vessel (who is the owner/operator, what documentation is needed).
Coastal/state permits for mooring, seabed impact, navigation markers/lights, marine protected areas.
Environmental compliance: sewage/blackwater handling, greywater, fuel storage (if any), antifouling coatings.
Safety baseline: railings, life-saving appliances, fire extinguishers, electrical standards, lightning protection.

Recommended approach (commercially)

Engage a marine surveyor early and document a standard “survey pack” for each build.
Consider designing to a recognized standard where feasible (e.g., guidance from a classification society such as ABS/DNV/LR), even if you do not fully class the unit initially.
Create a buyer-facing Permitting Kit: drawings, mooring loads, nav light plan, environmental statements, operating procedures.

8) Insurance and Liability (Often the Sales Gate)

Insurances you may need

Product liability (claims arising from design/manufacturing defects)
Marine general liability (during assembly/testing/launch)
Builder’s risk / cargo (in transit and during construction)
Professional liability if you provide design/engineering services

Customer insurance enablement

Provide stability data, operating limits (sea state/wind), maintenance schedules, and inspection records.
Offer an annual inspection program (paid) to keep units insurable.

9) Sales Model: How You Get Paid and Reduce Risk

Commercial terms that work for custom marine builds

Deposit + progress payments tied to milestones (e.g., fabrication complete, shipped, assembled, commissioned).
Change order policy: customer-requested changes affect price and schedule.
Clear delivery definition: “delivered ex-yard,” “delivered afloat at port,” or “installed at site.”
Warranty boundaries: corrosion, storm damage, misuse, lack of maintenance, third-party modifications.

Go-to-market tactics (Caribbean)

Anchor customers: resorts and dive operators (they buy outcomes, not engineering novelty).
Offer “proof packages”: 3–6 month pilot rental, then convert to sale.
Create a standard operating manual and maintenance plan (customers want predictability).

10) After-Sales Support: Make It a Profit Center (and Reputation Shield)

Support offerings to standardize

Annual service contract: anode replacement, cable inspection/tension checks, coating touch-ups, propulsor inspection.
Remote monitoring: solar/battery health, bilge alarms (if any), GPS drift alerts.
Spare parts kits: cables, shackles, turnbuckles, anodes, critical fasteners, seals.

Field service network

Partner with 1–2 marine service providers per key island cluster.
Train them and certify them for warranty work (reduces your travel costs).

11) Risk Register (Business-Focused)

Risk	Business Impact	Mitigation
Permitting delays / denials	Lost sales, stranded inventory	Permitting kit + pre-identified “friendly” sites; sell where rules are known first
Hurricane loss	Catastrophic financial + brand damage	Defined storm procedures, tow plan, insurance, conservative operating envelope
Corrosion / fatigue failures	Warranty claims, lawsuits	Coating spec, anode plan, inspections, conservative design margins, documented QA
Oversize shipping surprises	Cost spikes, missed delivery dates	Design-for-containerization; lock freight quotes early; prototype shipping trial
Supplier quality variation	Rework, delays	Approved vendor list, third-party inspection, staged payments tied to QA
Insurance unavailability	Customers cannot buy/operate	Surveyor documentation; standard compliance; insurer conversations before launch

12) What to Do Next (Concrete Checklist)

Choose your commercial classification (vessel vs floating structure) for the first product version.
Build a “compliance & insurance pack”: drawings, operating limits, maintenance, inspection checklist.
Run an FTZ location bake-off: score 2–3 candidate yards using the criteria in Section 6.
Lock supplier QA plan in China: inspection hold points + corrosion/coating requirements + shipping cradles.
Draft standard customer contract: milestones, delivery definition, warranty, storm responsibilities, change orders.
Pre-sell pilot units to 1–2 anchor customers with a rental-to-own or pilot discount in exchange for case studies.

Optional: Questions I Can Answer Next (If You Want)

Help you design a unit economics spreadsheet structure (columns/assumptions) for pricing.
Draft an outline for a Permitting & Insurance Package that sales can hand to resort developers.
FTZ site comparison: if you share 2–5 candidate ports, I can produce a scorecard you can use during calls/site visits.
Recommend a milestone-based payment schedule appropriate for custom marine fabrication.
