Pros and cons
Marshall Islands (RMI)
Pros
- Strong US regulatory alignment.
- First-class casualty investigation team.
- Offshore + LNG sector expertise.
Cons
- Slightly higher registration cost than LISCR.
- Fewer African-based crewing offices.
Liberia (LISCR)
Pros
- Longest FoC history — 1949.
- Deep tanker sector penetration.
- Broad African seafarer intake pipeline.
Cons
- Occasional political noise from Liberian domestic politics.

Common misunderstandings
- 'FoC = unsafe.' Both RMI and LISCR are Paris + Tokyo MoU white-listed with QUALSHIP 21 — better PSC records than many national flags.
- 'RMI is a US territory.' No — RMI is a sovereign nation in free association with the US. IRI is a private US corporation contracted to administer the registry.
