Anguilla, Caribbean — Solar-Powered Trimaran Seastead
The combination of a solar-powered seastead with extended range, on-board freezing, and comfortable living quarters fundamentally changes the economics of fishing from Anguilla. Current local fishermen are limited by:
| Species | Typical Size | Method | Value (USD/lb) | Notes |
|---|---|---|---|---|
| Mahi Mahi (Dorado) | 15-40 lbs | Trolling, jigging | $6-12 | Very common at FADs, aggressive feeders |
| Yellowfin Tuna | 20-150 lbs | Trolling, chunking | $8-18 | School around FADs, strong fighters |
| Wahoo | 20-80 lbs | High-speed trolling | $8-14 | Fast movers, excellent eating |
| Blackfin Tuna | 10-30 lbs | Jigging, chunking | $6-10 | Smaller tuna, abundant at FADs |
| Marlin (Blue/White) | 100-500 lbs | Trolling | $5-10 | Trophy catch, near deeper FADs |
| Amberjack | 20-80 lbs | Bottom jigging near FADs | $6-10 | Hold deep around structure |
Q: Can the seastead itself work as a Fish Aggregating Device (FAD)?
Yes, absolutely. Any large structure in open ocean water attracts fish. The seastead has multiple features that make it an excellent FAD:
In the open Caribbean, fish actively seek any structure. The seastead would function as a premium drifting/anchored FAD.
Q: How long must the seastead stay in one spot to attract enough fish for a family?
Estimated timeline:
Practical answer: After 3-5 days of station-keeping, a family should be able to catch plenty of fish for meals. After 1-2 weeks, the fishing would be reliably excellent. With night lights and chum deployment, these timelines could be shortened significantly.
Note: These timelines assume open ocean location away from other FADs. Near an existing FAD, fish are already present and the seastead augments the existing aggregation immediately. At a freshly deployed FAD, the seastead accelerates the colonization process.
Q: If the seastead moves at 0.5 or 1 MPH, would fish follow or flee?
Likely outcome: Most associated fish would follow, especially at 0.5 MPH.
Real-world comparison: Ocean currents in the Caribbean regularly move at 1-2 knots, and drifting FADs move with these currents while maintaining their fish populations. Your seastead moving at 0.5-1 MPH would be well within the range that fish tolerate and follow.
💡 Strategy: Move between FADs at higher speed (seastead can do ~4-5 knots with RIM drives), then slow to 0.5-1 MPH while fishing, or go to full station-keeping at a productive FAD.
Q: Would night lights help?
Enormously yes. Night fishing lights are one of the most effective fish aggregation techniques:
Estimated power draw: Underwater LED arrays of 200-500 watts would be transformative and easily sustainable with the solar/battery system.
Q: Would a chum system help?
Yes, very effective. A systematic chumming program would:
Design recommendation: A dedicated chum cooler/grinder with a slow-release dispenser (timed drip or auger system) over the side, ideally near one of the fishing deck areas.
Yes, but with caveats. A partially-automated system is very feasible today. A fully-automated system (that handles everything from baiting hooks to storing fish in the freezer) is possible but will have edge cases requiring human intervention in early versions.

The commercial package is designed to pay for itself within one or two fishing seasons. At $8-15/lb for mahi mahi and tuna, catching 50-100 lbs per trip 2-3 times per week generates $4,000-$13,000/month in gross revenue with near-zero fuel costs.
Deploy 5-10 anchored FADs at strategic locations 30-200 miles from Anguilla, creating a "fishing highway" that the seastead can patrol over multi-day trips.
| FAD | Distance | Direction | Depth | Target Species | Notes |
|---|---|---|---|---|---|
| FAD-1 (Close) | 30 miles N | North | 500-800m | Mahi, Blackfin Tuna | Easy day trip, good for quick harvest |
| FAD-2 (Medium N) | 60 miles N | North | 1000-2000m | Yellowfin, Mahi, Wahoo | Deeper water = bigger fish |
| FAD-3 (NE Channel) | 80 miles NE | North-East | 1500-3000m | Large Yellowfin, Marlin | Near Anegada passage — migration route |
| FAD-4 (NE Deep) | 120 miles NE | North-East | 2000-4000m | Big eye tuna, Marlin, large Mahi | Open ocean — premium pelagic territory |
| FAD-5 (East) | 100 miles E | East | 2000-3000m | Wahoo, Yellowfin | Less fished — virgin territory |
| FAD-6 (Far East) | 150 miles E | East | 3000-4000m | Large pelagics | Remote — only seastead can practically reach |
| FAD-7 (SW edge) | 40 miles W-NW | West-Northwest | 600-1200m | Mahi, Blackfin | Alternative direction for variety |
Estimated catch: 300-800 lbs of mixed pelagics over 5 days.
Estimated revenue: $2,400 - $12,000 depending on species mix and market prices.
Fuel cost: $0 (solar).

| Monthly Operating Cost Savings | $2,150 - $4,900/month | ||
| Scenario | Trips/Month | Avg Catch/Trip | Avg Price/lb | Monthly Revenue |
|---|---|---|---|---|
| Conservative (private, supplemental income) | 8 (2/week) | 50 lbs | $8 | $3,200 |
| Moderate (part-time commercial) | 12 (3/week) | 100 lbs | $10 | $12,000 |
| Aggressive (full-time commercial) | 20 (5/week) | 150 lbs | $12 | $36,000 |
| Multi-day expeditions | 4 (1/week, 5-day trips) | 500 lbs | $12 | $24,000 |
Commercial Fishing Package Cost: ~$21,000 - $44,000
Monthly net profit improvement (vs traditional): $4,000 - $20,000+
Payback period: 2-11 months depending on intensity of fishing operation
Even at the conservative end, the fishing package pays for itself quickly. The zero-fuel-cost advantage is transformative in a region where diesel is expensive.
