Option B - Project / refit or rebuild

Summary

Fastest path to "floating platform", but can be the slowest path to "reliable and finished".
Success depends on donor selection, survey quality, and controlling scope.

Donor selection filters (first pass)

Hard constraints: draft/beam/clearance/interior height feasibility.
Structural integrity and moisture history.
Engine hours and access for service.
Existing electrical condition (wiring quality, corrosion, panel standards).
Layout feasibility for king owner's suite + required heads/showers.

Refit scope buckets (to estimate later)

Structural repairs: hull/deck core, bulkheads, chainplates, bridge deck.
Propulsion: engines, saildrives/shafts, exhaust, cooling, fuel system.
Electrical: new generation/storage/distribution; safety and labeling.
Plumbing: watermaker, tanks, pumps, heads/holding.
Rigging and sails: standing and running rigging replacement cycles.
Safety and compliance: fire suppression, life raft, EPIRB, lighting.
