Bareboat charter registration allows a vessel to fly the flag of one state (the bareboat-in flag) while retaining its underlying registration in another (the parent flag). This creates distinct labour, tax, and regulatory outcomes than the parent flag would. This directory covers the 12 major bareboat-in registries + the parent flags each accepts.
Bareboat charter registration is often the mechanism behind unusual flag-owner combinations you see on ship records — a Cypriot owner flying Malta flag, a Danish owner on DIS, a Norwegian owner on NIS. Each generates distinct labour + tax outcomes.
Maltese bareboat-in is popular for Cypriot + Greek owners seeking EU-flag + tonnage-tax benefits. Duration typically 2 years renewable.
