The table below gives rough fee estimates in USD for a small, non-commercial, family seastead with two adults, using temporary tension-leg anchoring with helical seabed screws or equivalent approved mooring anchors.
Assumptions: two adults; no marina berth; no import duty/VAT; no hardware, installation, diver, towage, or maintenance costs; no customs bond; no insurance; no paid local agent unless typically unavoidable; and no commercial passenger activity. “Anchoring/seabed” includes estimated cruising permit, harbor/port fees, mooring-field fees if likely, and a nominal temporary seabed-use authorization. “People” includes estimated visitor visa extensions, digital-nomad/remote-work fees where likely, and basic immigration/person fees.
| Country / Area | Likely Regulatory Posture | 1 Week Total | 1 Month Total | 3 Months Total | 6 Months Total | Permission Risk |
|---|---|---|---|---|---|---|
| Bahamas | Likely handled first as a visiting yacht/cruising permit, but helical seabed screws would probably need local anchoring or environmental approval, especially near reefs, marine parks, or settlements. | $350 Anchoring/seabed: $350; people: $0 | $600 Anchoring/seabed: $600; people: $0 | $1,250 Anchoring/seabed: $1,200; people: $50 | $3,800 Anchoring/seabed: $2,400; people/remote-work or extensions: $1,400 | Medium |
| Belize | Belize has many marine reserves and sensitive reef areas. A screw-anchor tension-leg setup would likely require Port Authority and/or protected-area permission. Easier outside reserves, harder near the barrier reef. | $530 Anchoring/seabed: $450; people: $80 | $1,000 Anchoring/seabed: $900; people: $100 | $2,500 Anchoring/seabed: $2,200; people/extensions: $300 | $4,800 Anchoring/seabed: $4,000; people/extensions or remote-worker fees: $800 | High |
| Panama, Caribbean Side | Panama is relatively yacht-friendly. A temporary seastead would still need maritime authority approval and possibly local anchorage authorization. Remote-work/long-stay options are comparatively favorable. | $350 Anchoring/seabed: $300; people: $50 | $550 Anchoring/seabed: $500; people: $50 | $1,000 Anchoring/seabed: $900; people: $100 | $2,100 Anchoring/seabed: $1,500; people/remote-worker fees: $600 | Medium |
| Grenada | Grenada is yacht-friendly, but fixed seabed tackle still needs approval. Long stays may be possible through visitor extensions or Grenada’s digital-nomad style program. | $330 Anchoring/seabed: $250; people: $80 | $600 Anchoring/seabed: $500; people: $100 | $1,450 Anchoring/seabed: $1,200; people/extensions: $250 | $4,400 Anchoring/seabed: $2,400; people/digital-nomad couple estimate: $2,000 | Medium |
| Turks and Caicos | More expensive and more restrictive than many Caribbean locations. Anchoring damage concerns are significant. A tension-leg seabed installation would likely need specific written permission. | $850 Anchoring/seabed: $700; people: $150 | $1,650 Anchoring/seabed: $1,400; people: $250 | $3,400 Anchoring/seabed: $2,800; people/extensions: $600 | $6,700 Anchoring/seabed: $5,500; people/extensions: $1,200 | High |
| Antigua and Barbuda | Yacht-friendly, especially around Antigua, but a semi-permanent tension-leg setup would probably need port, fisheries, and environmental approval. Digital-nomad residence has historically been available. | $400 Anchoring/seabed: $300; people: $100 | $800 Anchoring/seabed: $650; people: $150 | $1,800 Anchoring/seabed: $1,500; people/extensions: $300 | $5,000 Anchoring/seabed: $3,000; people/digital-nomad couple estimate: $2,000 | Medium |
| Anguilla | Smaller jurisdiction with stricter control of coastal waters. A fixed mooring/seabed system would likely need explicit approval. Digital-nomad/extended-stay fees can be relatively high. | $470 Anchoring/seabed: $350; people: $120 | $1,000 Anchoring/seabed: $800; people: $200 | $2,300 Anchoring/seabed: $1,800; people/extensions: $500 | $6,200 Anchoring/seabed: $3,200; people/digital-nomad family estimate: $3,000 | High |
| British Virgin Islands | BVI has extensive mooring fields and strong controls in popular anchorages. A private screw-anchor tension-leg system would likely be difficult unless placed in a specifically approved area. | $650 Anchoring/mooring: $450; people/cruising fees: $200 | $1,650 Anchoring/mooring: $1,300; people/cruising fees: $350 | $4,500 Anchoring/mooring: $3,600; people/extensions/cruising fees: $900 | $8,800 Anchoring/mooring: $7,000; people/extensions/cruising fees: $1,800 | High |
| French Polynesia | Many anchorages now have local limits, designated zones, or mooring rules. A fixed temporary mooring would likely require commune, port, or maritime authority approval. Human long-stay visa fees are often modest, but paperwork is significant. | $330 Anchoring/seabed: $250; people: $80 | $820 Anchoring/seabed: $700; people: $120 | $2,250 Anchoring/seabed: $2,000; people/visa fees: $250 | $4,300 Anchoring/seabed: $4,000; people/long-stay visa fees: $300 | High |
| Thailand, Andaman / Gulf | Thailand has many informal yacht anchorages, but fixed seabed tackle or a seastead-like structure would attract scrutiny. National parks and marine protected areas are especially sensitive. Long-stay visa options may be available. | $280 Anchoring/seabed: $200; people: $80 | $550 Anchoring/seabed: $450; people: $100 | $1,470 Anchoring/seabed: $1,200; people/visa fees: $270 | $3,040 Anchoring/seabed: $2,500; people/long-stay or DTV-style fees: $540 | High |
| Cayman Islands | Likely one of the most restrictive and expensive options. Coral and seabed protection are major concerns. A helical-screw tension-leg system could require formal seabed licensing and environmental review. | $1,100 Anchoring/seabed: $900; people: $200 | $2,400 Anchoring/seabed: $2,000; people: $400 | $6,000 Anchoring/seabed: $5,000; people/extensions: $1,000 | $11,500 Anchoring/seabed: $10,000; people/extended-stay estimate: $1,500 | Very High |
| Malaysia, Langkawi | Langkawi is comparatively yacht-friendly, with many anchorages and lower fees. A fixed seabed system would still need local marine/harbor approval, but this is one of the lower-cost candidates. | $150 Anchoring/seabed: $100; people: $50 | $320 Anchoring/seabed: $250; people: $70 | $850 Anchoring/seabed: $700; people/extensions: $150 | $2,000 Anchoring/seabed: $1,500; people/nomad-pass or extensions: $500 | Medium-Low |
Suggested next step: before choosing a country, ask a local maritime attorney or yacht agent for a written opinion on whether the seastead would be classified as a yacht, floating home, vessel at anchor, moored vessel, aquaculture-style floating structure, or fixed seabed installation. That classification will dominate the real permitting cost.
