This document discusses optional fishing packages for the solar seastead, addressing your questions about using it as a FAD, automatic fishing equipment, and lists of recommended gear with estimated China-sourced prices.
Yes, very likely. The seastead has many of the classic features that make FADs work:
How long to attract enough fish for a family? In the Caribbean, anchored FADs typically start showing baitfish within 24–72 hours and pelagics within 3–10 days. A floating, drifting seastead is similar to a drifting FAD — these are well known to attract mahi within hours to days because pelagics are actively cruising for floating objects. Realistically: 1–3 days of staying near the same area should give a family plenty of mahi/jacks/small tuna. If you stop near an existing anchored FAD, fishing should be excellent within minutes.
Mostly yes for mahi-mahi and small tuna, partly no for skittish reef fish. Mahi are famous for following slow-moving floating objects (including sargassum mats drifting at exactly those speeds). At 0.5–1 mph the seastead is essentially "drifting" from a fish's perspective and the shade/structure illusion is preserved. Above ~3 mph most pelagics drop off. So 0.5–1 mph is actually an ideal trolling speed and lets you cover ground while still being FAD-like.
Definitely helpful. Underwater green or blue LEDs (5,000–15,000 lumens) attract plankton → baitfish → squid → tuna/mahi. This is standard practice for night fishing in the Caribbean and Pacific. With abundant solar+battery power, running 50–200 W of underwater LEDs all night is trivial. Strong recommendation: include 3 underwater lights (one near each leg) as standard.
Moderately hard but very doable as a project. Realistic phases:
For v1, target Phase 2: let people fish while they sleep, and ring an alarm when help is needed. This is a great differentiator and probably saleable as an option within ~$8K–$15K of added hardware.
Yes — a small dedicated chum freezer (or insulated bin with a sealed lid) is a great idea. Keep scraps from yesterday, grind, freeze in blocks, and drop a block in a mesh bag overboard the next morning. Sized at maybe 50–80 liters separate from food/catch storage.
Aimed at a family living aboard who wants to catch enough fish for meals and recreation, with some surplus.

If the customer chooses a fishing package, several things become much easier (and cheaper) if they are designed into the seastead from the beginning rather than retrofitted. Please make sure the naval architect plans for the following:
| Package | Approx. China Cost | Suggested Retail (2× markup) |
|---|---|---|
| Private / Family Fishing | ~$3,840 | ~$7,500–$8,500 |
| Commercial Fishing | ~$27,880 | ~$50,000–$60,000 |
Both are very attractive option add-ons. The commercial package in particular pairs beautifully with the seastead's solar / freezer / long-endurance profile — an Anguillan fisherman who today goes 10–20 miles out for a single day could instead spend 5 days circulating between FADs 30–200 miles out, returning with several times more fish at zero fuel cost. That is a real economic story, and the fishing-package upsell makes it concrete.
